How to properly set the ignition on a lawn mower

It doesn’t matter what kind of equipment, and especially garden, working in quite difficult any conditions, asks for maintenance. Even the usual and small service significantly increases the resource of the work of this technique, and does the work itself more ordinary and solid. And the motors are starting “from half a tyk”, and work massively and without a roar and rubbish.

Such a small service of its own technique is provided by its owner himself, without the need to carry it to the special service. On the example of this article, I will tell you about the necessary works that need to be carried out on a gasoline lawnical mower. Other benzocosyles in our client will be approximately the same.

After the last season and wintering in a cool barn, the lawn mower requires cleaning and lubrication. External cleaning was made in the fall, before storage, at the moment it is necessary to carry out it more painstakingly and prepare the lawn mower for the battle with the grass and weeds.

First of all, you need to remove protective covers from the engine of a gasoline lawn mower. This will provide easier access to the main nodes and facilitate the work. We will also be able to look around the starter device, remove dust from under the casing, particles of dry grass and the rest of the garbage, interfering with normal cooling of the motor. And it is no secret to anyone, the air on its quality is influenced by specifically the cleanliness of the motor.

The motor casing (in my MTD SP 48 model) is attached with 4 screws (poses. 1 in the photo). We pass the starter’s handle through the lumen and remove the casing.

Now our company can remove the starter device and gain access to the main motor nodes. For this purpose, we unscrew 3 screws, which strengthen both the starter launching and the fairing of the fan-butter.

The starting device is carefully cleaned from garbage and examine the starting cable. If it is damaged, you will have to change it to a new one, having dismantled it himself. There is an option to return an option to a light “disgusting” cable using a certain elastic glue (rubber, PVA). T.e. such, who would glue with each other villi, but the place of adhesives remained elastic.

How to set the ignition?

Having removed the fairing of the fan painstakingly clean the fairing itself and the fan blades using a stiff brush with a long pile. Now let’s move on to the motor nodes.

The ignition system of the lawn mower is arranged so. A constant magnet is built into the flywheel of the motor. When he “flies” past the poles of Magneto (pos. four.5 in the photo), the magnetic flux is closed and the electric motor is induced in the Magneto coil. Using an electrical circuit, the myth is shortened in time and a powerful pulse is formed, sufficient for the electronic breakdown of the gap of the spark plug (pos.one)

Specifically speaking the quality of the spark and ensures the ease of launching the gas mowing motor. Therefore, we do such operations.

At first we unwind the spark plug and examine it. If the lawn mower had to work perfectly last season, it is better to replace it to the latest, sell it if the ancient still looks decent. New and further will be better. Obviously, for earlier you need to check the gap between the electrodes of the candle. Normally set it by bending the Mr-shaped electrode up to 0.5-0.6 mm, already. Magneto may not be enough at different power, and the spark will be called weak or it will not be at all.

Now we’ll get Magneto. If earlier the lawn mower started up without much effort, then Mosno will be limited to cleaning and checking the wires. In that case, there were tasks earlier, we will check the gap between the magneto and the flywheel. The smaller it is, the better the spark. But you can not press Magneto to the flywheel in attraction. There is a common method of checking and installing such a gap. We take a duralumin beer jar and cut out a strip from it. Weakening the mount of the magneto and laying a strip of aluminum between his poles and the flywheel, we press the magneto and tighten the bolts. As a result, we pull the strip with pliers. I have repeatedly used this method and always gave a positive result.

Setting the ignition system.

In most modern models of chainsaws and trimmers, it is not required to set the angle of the ignition. This angle is determined by the position of a special groove on the flywheel for the binding attachment to the crankshaft and the magnets installed on the same flywheel.

It is only necessary to properly set the gap between the flywheel and the ignition coil. How the ignition system works on the chainsaw, what is the advance angle. How to set the ignition on a chainsaw: an algorithm for checking and adjusting. Depending on the model of the tool, the size of the gap can be of different. It usually is 0.2-0.4 mm.

Since the flywheel is round, the usual car probe for these purposes will not work. It would be technically competent to set a gap on a special template. How to set a ignition on a chainsaw? I ignition setting technique for setting up installation. But it is not always possible to purchase it. How to set a ignition on a stihl chainsaw.

Buying such an expensive template for one.time use is unreasonable. Instead of a company template, you can use a strip from a plastic bottle of water. How to adjust the tension of the chain on the chainsaw for elasticity the circuit, how to correctly. Cut a strip from a bottle in a place where there is no embossed embossing.

Further, the actions for the exhibition of Zazaor are approximately the same for both chainsaws and for trimmers:

  • Loosen the ignition fastening bolts.
  • Suppry the magnets on the flywheel to the ignition coil
  • Clutching between the flywheel and the coil of the plate from under the bottle, tighten the fasteners.
  • Remove the strip
  • Scroll the flywheel 360 degrees several times, monitoring that he does not cling to the coil anywhere.

All. The gap between the coil and the flywheel is exhibited.

The repair of the ignition coil is impossible and impractical. The following is a list of ignition coils that can be bought on our website

How to set a ignition on a trimmer

Often, owners of gasoline cos are faced with the fact that ignition does not work on their technique. In most cases, the problem is really in this node. To fix it, you need to adjust the ignition on the trimmer. But at the same time, there are frequent cases that the ignition coil is working and a breakdown should be sought elsewhere. The ignition system is arranged equally on four.stroke and two.stroke internal combustion engines, therefore, the correction of the malfunctions of this node is carried out in a similar way. In addition, the technique of different brands has an almost identical design of this most important component of the tool, which means that the process of adjustment will be identical for both the trimmers “Soyuz” or “Prostr”, and for Huter or samples of other brands.

The ignition system is arranged in a similar way on the technique of various brands, so the process of adjusting will look the same. The differences, if they are, are insignificant. They are mainly associated with the disassembly of technology. For example, removing the casing from the engine on different trimmers is performed with some differences. So, on the devices of Patriot, you must first twist the bolts and disconnect the air filter housing with a slotted screwdriver. After that, it will be very easy to remove the plastic casing. A detailed diagram and a trimmer for grass of a certain model are usually shown in the instrument operation instructions.

So, you can adjust the ignition for a gasoline trimmer for grass with your own hands. This process is simple if you know the correct procedure. But preliminarily it is necessary to exclude the likely malfunctions of other nodes and parts, for example, the spark plugs or magneto, which may cause the absorption of the motor motorcycles. However, analyzing the technique of different brands, it is necessary to take into account the likely differences in the design, which are described in detail in the user guide.

How to set the ignition on the trimmer Husqvarna 128r

On gasoline trimmers, both two.stroke internal combustion engines (ICE) and four.stroke. Alas, the ignition system is no different from them, because the repair and configuration of this complex of accounting programs of fuel ignition will be similar for various types of internal combustion centers.

The ignition system of a two-stroke ICE consists of 2 parts: flywheel and coils (magneto). The figure below shows how they look.

There is a impeller on the flywheel, which works like a fan for cooling a motor. Also on one side of the flywheel are unchanged magnets, in the figure are shown by the arrow.

When the flywheel rotates in the coil, an electronic current is produced, which serves for a spark on the spark plug. The spark occurs just when the magnets are specifically under the magneto.

Sometimes, when the engine does not start, you will need to adjust the ignition. Of course, at first it is necessary to check the serviceability of a candle and a high.voltage cable with a cap.

It is necessary to adjust the ignition on a two.stroke engine in order to ensure timely ignition of fuel in the combustion chamber of the motor. Below is a scheme from which, of course, the mechanism of operation of the internal combustion engine is engaged in the.

The spark in the candle should appear at the time of compression of the fuel piston, when it does not reach the top of the upper dead point (VMT). When the piston passes through the VMT, the fuel consistency is ignited, under the influence of which the piston goes down under the influence of energy of the explosion.

If for any reason (for the most part this happens due to the shift of the flywheel to the shaft relative to its initial position), the fire of the fuel occurs about 30 years, the piston passes, then it is fraught with back, and the crankshaft is scrolling in the revolutionary direction. Such a movement can destroy the starter node, cut off the launch cord, etc.D. In our version there is a premature ignition of fuel.

We select the correct gap on the ignition coil of the lawn mower Union

You will also like the ignition on the trimmer later: the piston after compression of the fuel, which did not burn out, goes down, and in such circumstances there is a spark. Under such circumstances, the engine will either not start or significantly lose power and will not gain momentum.

But such obstacles with the wounded as it is also called the late ignition on two.stroke ICE are quite occasionally found, since the flywheel with magnets is already established in the correct position, which is completely synchronized with the movement of the piston. Also, the flywheel is fixed on the shaft using a key and nut. Therefore, the incorrect installation of the part is excluded.

Mainly the ignition adjustment is to set the correct gap between the magneto and the flywheel.

Magneto is the main detail in the ignition system of the motor and this is a coil with primary and secondary windings located around the core. Often, on the basis of a Magneto malfunction, a spark is lost on the spark plug, and fuel ignition does not occur. To check the coil, you need to use the tester, and fulfill subsequent deeds.

  • On the tester, going into the resistance measurement mode, it is necessary to set 200 Ohms. This method will be checked by the primary winding.
  • Connect one tester electrode to the “mass” of the coil, and the 2nd-to the contact emerging from the magneto. Normally, resistance is from 0.4 to 3.5 Ohm.
  • To check the secondary winding, you need to install the device switch by 20 kOhm. Further, one probe of the device is inserted into the cap of the candle, and the 2nd-is connected to the “mass”. Normally, the characteristics of the resistance are required to be in the spectrum of 4-6 kOhm and higher (located depending on the model).

When a circuit is broken, the device will demonstrate infinity, and when close. 0 (zero).

When you do not have a tester, use the subsequent method, showing great accuracy so that the electrode does not touch the cylinder, the coil will burn out another way.

  • Remove the cap from the candle. You do not need to twist the candle in order to save compression.
  • In the cap, you need to stick a nail without a hat. The nail owes such a diameter to hold perfectly in the cap.
  • Tie a cap with a nail to the cylinder, using the dielectric, such a macar that the gap between the electrode and the cylinder body is from 5.5 to 7 mm (however does not touch the “mass”).
  • Using the starter, make a couple of times the imitation of the start of the motor. The ignition button is desirable.
  • Watch whether the spark arises, and what color it has.

Normally, a spark can be strong, snow.white or have a bluish colver. If the spark is weak, and its color is orange or yellowish. it says a faulty magneto.

How To Bypass Your Riding Mower Seat Switch

It should also be taken into account the fact that from time to time Magneto in a cool state can give a good spark. Alas, after heating due to internal defects, it ceases to create a current. As the coil cools, the trimmer for the grass starts again and a certain period works until Magneto heats up again. Such a reel needs to be replaced.

From time to time, a light of ignition can cause a similar case with heating if the coil is in good condition, therefore it is necessary to inspect both parts.

The ignition on the trimmer is adjusted quite easily.

    Remove the casing from the motor, unscrewing what remains to our client holding its bolts. For example, on the Patriot gas.cave (Patriot) PT 2540, to remove the casing, you need to unscrew the air filter housing, and remove it with a flat screwdriver from the latches. Then the plastic case will simply be removed.

Husqvarna adjustment

Husqvarna carburetor adjustment of the grass is identical to the Husqvarna chain carburetor adjustment.

We do the adjustment of the Husqvarna carburetor if:

  • The engine is ended with the engine (after using the first 4-5 liters. fuel);
  • the quality of fuel components has changed (octane number of gasoline and brand of oil);
  • The air temperature and its vacuum (height, heat, coolness, frost) have changed greatly;
  • The beginning of the operating season of a trimmer for Husqvarna grass (in early May, after winter storage);
  • The adjusting screws themselves checked from vibration;
  • The engine load has changed.

And also, to be sure that the Husqvarna engine works as expected and that the maximum efficiency of the trimmer for grass (lawn mowers, motorcycles) is ensured.

Husqvarna carburetor adjustment

Before adjusting Husqvarna, make maintenance of a trimmer for grass (wash the lawn mower and engine, replace the spark plug, eliminate minor defects).

Be sure to wash the foam element of the air filter. Wash the element in warm water with soap, then squeeze and dry (or replace it if it is old or damaged).

Note: If you adjust the Husqvarna carburetor with a dirty air filter, then after cleaning the air filter, the fuel mixture will become much poorer (which can lead to poor operation or even engine breakdown). Install a trimmer head with a cord of the maximum permissible diameter and standard length (to a cutting knife in additional protection) to create a load on the engine while adjusting the high speed of the Husqvarna carburetor. Get the lawn mower according to the leadership of Husqvarna and warm for 10 minutes (if at the same time the trimmer head rotates at idle speed, then the idle screw, t.e. Lower, it is necessary to turn counterclockwise until the rotation of the trimmer head stops). Carefully turn both needles (right and left) in the middle position between fully twisted and completely screwed (do not cure the stopper!, This can lead to breakdown of the Husqvarna engine).

Husqvarna carburetor adjusting screws for adjusting the carburetor: right, left and lower.

1) The right screw l. regulates the enrichment of a mixture of low revolutions (regulated first): Find the maximum idle speed, slowly turning the right screw to the right and left. Then turn this screw on ¼ turn counterclockwise. Note: from the Husqvarna plant, the right screw was completely unscrewed (at 0.5 turnover). Now he is looking at “11 hours”. 2.

The adjustment of the idle speed is considered to be correct when:

  • The cold engine is stable at idle.
  • The hot engine has not highly high speed speeds.
  • Before the rotation of the trimmer head, a sufficient supply of revolutions remains.
  • The engine works steadily in any position (for example, with a sharp lowering knife).

Note: from the manufacturer (Husqvarna), the idle screw from the fully twisted, was twisted at 8 full revolutions and “2 hours” (now it remains). Husqvarna.2.recommended idle gas mowing engine. 2.900 rpm. 3) Left screw h. regulates the enrichment of a mixture of high revolutions (is regulated last). It regulates maximum speed, engine power, temperature and fuel consumption.

Note: the Husqvarna engine should not operate at full speed for more than 10 seconds!

  • Open completely the throttle (give full gas) and slowly turn the left screw clockwise until the speed of the Husqvarna engine is reduced (by ear).
  • Then turn the left screw very slowly counterclockwise until the engine starts to work uneven.
  • After that, turn the screw slowly back to a slight distance clockwise until the Husqvarna engine starts to work smoothly.

This is where the HUSQVARNA adjustment is completed.

Note: recommended by the highest possible speed of the Husqvarna engine. 11.500 rpm. The maximum output capacity of the Husqvarna 333R lawners engine is 1.6 kW (2.1 l.With.) at 8.400 rpm.

Note: on the new trimmer Husqvarna from the manufacturer (Husqvarna), the left screw was completely unscrewed (by 0.5 turnover) and blocked (bay) with solid plastic, which I drilled after the guarantee period. Now the left screw (like the right one) looks at 11 hours approximately.

We check the correct settings of the Husqvarna carburetor

The engine is quickly, evenly and confidently gaining momentum, and a little four at maximum speed, the T-35 trimmer head should not rotate at idle.

Reference. Read to understand what you are doing!

The desired composition (quality) of the fuel mixture is adjusted (changed) by turning the screws for adjusting the supply of fuel into the flow of sucked air (right and left). The amount of the mixture of the throttle doses to the cylinder. If you turn them clockwise, then the mixture is impoverished in the cylinder (less fuel in the ratio of air/fuel) and engine speeds increase, while the Husqvarna engine is softer (it is slightly gaining speed) and the power drops strongly and the power drops strongly. In addition, having increased speeds, it enters the cylinder on the depleted mixture with gasoline less oil (worse lubricant) and so you can start the engine. Well, the trimmer for the grass will be bad to start. If the screws turn counterclockwise, then the mixture is sucked into the cylinder is enriched (more fuel in the ratio of air/fuel) and the engine speed decreases, while more gasoline and oil (preferably thrust, better lubrication), but the Husqvarna engine gets into the cylinder. “Spins” poorly (poorly gaining momentum) and more than a carriage is formed in the cylinder!

Setting up a carburetor of a lawn mower with three adjusting screws

Before starting work, you need to place the lawn mower on a flat stable surface. Remove the chain in the opposite direction. There are motorcycles with two and three adjusting screws. Two screws most often equip the tools produced in China. Consider the adjustment of the carburetor Motokos with three screws.

Setting up a carburetor of a lawn mower with three adjusting screws

ignition, husqvarna, mower, diagnose

Before proceeding with the adjustment of the carburetor of the lawn mower, you need to rinse the air filter. Cleaning is carried out with water with a detergent or soap, and if necessary, a new. Often in the poor work of the carburetor, scibberries are guilty. In order to prevent the filter, it is recommended to clean the filter after every 10 hours of operation of the tool. Do not forget to check the condition of the candle, if there is a dozen, you need to clean it. Candles are consumables and have their own resource. To ensure good operation of the engine of the lawn mower, candles periodically need to be changed. Next, we evaluate how well the carburetor is fixed to the cylinder-piston group. After the preparatory manipulations are completed, you need to start the motor. Let the engine work for 5-10 minutes. Then you need to identify how many adjusting screws on your tool.

There are the following adjusting screws on the gasoline trimmer:

Fuel supply adjustment

At first you need to slowly tighten the screw adjustment screw for the fuel mixture. You need to do this until the engine starts to stall or stalls. Following this, if the engine did not stop working, you need to turn the screw for a quarter of turnover, and if it stalled, then by half the turnover. Next, you should have a stalled engine. Then you need to open the throttle and see how the speed is gaining. Turn the screw for a quarter of turnover again. You need to scroll until the engine begins to confidently gain increased speeds during cuffing. This is the right time when the engine works most economically. There are times when adjusting this screw does not give anything. Often the reason is in the factory spring that is located on this screw. This does not happen to all the tools. And if the spring turned out to be defective, then replacing it will not be difficult. A suitable spring can be purchased at any construction store.

Cooper adjustment

Following the adjustment of the fuel supply, we are accepting for the adjustment of the idle. To do this, you need to adjust the corresponding screw so that the engine works slightly accelerated at small speeds. But it is necessary to trace, for the immobility of the reel with fishing line and knives. Before the start of their movement, several revolutions should remain in stock. The movement of the coil and knives can subsequently lead to the rapid wear of the clutch. Having noticed that the engine starts poorly, you need to increase the number of revolutions at idle. With an increase in revolutions, the fuel mixture is saturated with air, which leads to power loss.

The main signs of the proper idle work:

  • Revolutions for a trimmer head;
  • Uninterrupted operation of the engine even when the position changes (sharp rise or descent of the knife);
  • Calm operation of the engine at a cold move;
  • Lack of increased speed of hot engine.

Maximum speed adjustment

Further, for the full tuning of the carburetor of the lawn mower, it is necessary to adjust the maximum speed. It will not be superfluous to look into the instrument operating manual and see the maximum speed value. This amount will help to determine the tachometer most accurately. If such a device was not at hand, we set up by ear. Barely determining the maximum speed of revolutions by ear, we begin adjustment. A screw for limiting maximum revolutions will help in this matter. Control the engine operation at maximum speed. If necessary, reduce speed, weaken the fixing nut and unscrew the screw. If the turnover is too large, then you will need to screw the screw. These actions must be done in order to protect the engine from overheating. Scroll the screw until the clear even operation of the engine is established.

After the work done, if everything is done correctly, the stable work of the tool is provided.

Understand this by the following signs:

Description and characteristics of gas stations 128r

The gasoline trimmer for grass 128R from Husqvarna is designed to process small and medium areas and is suitable for cutting grass near hard.to.reach places (flower beds, borders). The tool is equipped with a two.stroke engine, the power of which is 0.8 kW or 1.1 liters.With. The speed of rotation of the gasoline pump Husqvarna 128R reaches 11,000 rpm. The engine is designed using E-Tech 2 technology, which significantly reduces the amount of exhaust gases produced by the trimmer. Its volume is 28 cm 3.

To quickly turn on the device even after a long period of inaction, a primer for pumping fuel and the Smart Start system are built into it. The maximum width of the possible processing is 45 cm. Husqvarna 128R. a gasoline trimmer for grass with a straight bar and professional handles made in the form of bicycles. This allows you to significantly control the workflow and direction of the tool. The design with a rectilinear rod is considered the most reliable than curved. To facilitate the transportation of gasoline pumps, bicycle handles can be folded.

The weight of the device without fuel, installed cutting parts and protective casing is 4.8 kg. Thanks to this, the Husqvarna gasoline pump 128R can be used for a long time without interruptions. The fuel tank of a gasoline trimmer for grass is made of white plastic so that it is easier to control the amount of fuel remaining in it. Basin for gasoline is 400 ml. To launch a fuel pump, it is enough to pull the cord smoothly, since the necessary starting force was reduced by 40%.

  • a knife with 4 blades for hard and high grass or shrubs;
  • Trimmer head for grass (semi.automatic);
  • mounting belts for 2 hands;
  • a set of keys;
  • bicycle pen;
  • Operating and maintenance manual;
  • protective covering;
  • not assembled rod.

The trimmer fishing line is used to remove only small grass.

The Husqvarna launch button automatically returns to the starting position, so it is more convenient and faster to turn on the trimmer for the grass. A special knife for cutting grass does not crush it, but puts it in rolls. The case for protecting the disk and a trimmer for grass with fishing lines is the same, but there is no need to remove it during the replacement of the rigging.

The main problems and malfunctions of the carburetor.

Mesh filter. There are only two tasks with this element more often:

In order to find out the cause of the breakdown, the fuel filter lid is unscrewed to extract the mesh filter. If the mud just accumulated on it, then flushing in gasoline or purge will help.

With visible damage on the mesh filter, it is necessary to put a new. There may also be damage to the fuel supply pipe (during the repair they practice checking this element).

The starting device of the carburetor almost always does not work due to blockages. Should be used for flushing acetone or the same gasoline.

Purging parts of a carburetor with click of compressed air. permissible and comfortable repair practice.

The hull of throttles, places of ligaments of the parts of the carburetor, intake or graduation pipeline. all of the listed parts are subject to depressurization. You can probably check the simple method. spread the problem area with soap foam.

Husqvarna 125R Setting a carburetor without a tachometer (temporary solution)

How to adjust the carburetor if you need to work, and the service with a tachometer is far.

A combustible pump (its membrane) is sucked into the carburetor system. Then passes through the fitting in the carburetor. Then the liquid moves through the intake and exhaust valve of the pump. Filtered with a net. Husqvarna 137, 14, 435 and other models adjusting the carburetor. DIY Carburetor Carburetor. On the needle valve moves into the membrane chamber.

We offer to familiarize yourself with a hibiscus of triple

  • Air supply to the tube with an air septum (damper). The partition regulates the intensity of the air flow.
  • The fuel supply system is certainly narrowed by the mixer to accelerate the flow.
  • Gasoline through the float chamber and nozzle with narrowing. The chamber with a float regulates the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the tube with narrowing is already small. Thanks to the pressure drop, fuel seeps through a jickler.
  • Acceleration of the air flow contributes to the transfer of fuel (gasoline) and its spray. Ultimately, a fuel mixture of the desired proportion or density appears.
  • The air-fuel mixture seeps into the cylinder of the motor through the fuel tube.

The level of air density in the system depends on the area of ​​the open air damper. Husqvarna carburetor adjustment of the grass is identical to the Husqvarna chain carburetor adjustment. The more extensive the damper is open, the greater the fuel consumption and power.

Simply put, adjusting the carburetor on a benzocos. creating a good fuel consistency due to the correct air supply.

Repair of the Makita chainsaw carburetor. Makita chainsaw carburetor adjustment

Makita chainsaw carburetor adjustment affects the productivity of the device, quality of operation

For the correct setup of the working unit of equipment, it is important: to understand the principle of its operation, to have the necessary tools, to carefully relate to fasteners, as well as closely located elements responsible for the functioning of the chainsaw

Features of the Makita carburetor setup

Makita chainsaw carburetor operates on the same principle as carburetors released by other manufacturers. This important detail is responsible for mixing fuel with air. In order for the operation of the Makita chainsaw to be adjusted with the operation of the device. This will help protect the equipment motor.

  • eliminate the risk of creating a “poor” mixture by a carburetor;
  • minimize the risks of creating a oversaturated mixture, which negatively affects the work of the motor, provoking quick wear.

If you need a new carburetor on the Makita chainsaw (you will configure, focusing on standard instructions), choose the one that is identical to the original.

  • The basis of the basics is a tube for passing air, which is connected to the damper (in the middle). The location of this part affects the amount of air that comes to the engine when operating.
  • Diffuser. It is not difficult to identify it, with a thorough consideration of the components of the carburetor. This part looks like a narrow tube, the main function of which is the control speed adjustment of the air flows.
  • The channel supplying fuel from the float chamber (connected to the nozzle).
  • A separate design that is released against the background of others is a float chamber that looks like a standard tank for fuel liquids.

Randies for adjustment

Makita chainsaw carburetor adjustment is carried out with a set of adjusting screws that are in the case of this design:

  • a screw with labeling L. adjusts low speeds;
  • a screw with labeling h, at the expense of it, high speed settings are carried out;
  • screw t to configure the carburetor operation at idle.
  • The engine is left to warm up (run the chainsaw for 10 minutes).
  • Air filter check and cleaning this part.
  • Stop a circuit turning the screw with marking T (turn until the stop).

A tachometer is used to diagnose problems of carburetor operation.

Important! Masters advise listening to the sound that the screws make when turning. “Screeching” sound may indicate oversaturation of the mixture

Settings algorithm

Carrying out the carburetor of the chainsaw in two stages:

Important ! Some setting steps must be adjusted, depending on the model of the macita chainsaw. In order to do everything right, read the instructions

  • We turn the screws for adjusting high and low revolutions to the stop (turn clockwise).
  • At the time of the meeting of resistance, make a half turning back.

TRACK WITH THE MARKING T, move in the direction of the clockwise. Release it only when the engine starts to work stably. In this case, take into account that the chain at this stage should not move.

What to do if the engine turns off during the idle setting? In this case, it is important to quickly crank the screw until it stops (turn clockwise). If the manipulation leads to the movement of the circuit, the adjusting screw is slowly rotated to the previous position

How to check if the carburetor is correctly configured?

To do this, you need to accelerate the operation of the chainsaw. Run the engine at maximum speeds to objectively evaluate its work. When you click on the accelerator, the speed of rotation should reach approximately 15 thousand revolutions per minute. This indicator indicates that the tuning of the carburetor was successful.

If you cannot achieve such an indicator at large speeds, and acceleration is slowly passing, you need to adjust the carburetor again, working only with the screw on which there is labeling l. Rotate it counterclockwise. In this case, rotate the screw slowly so that the turn does not exceed 1/8 of the complete rotation.

If the problem arises the opposite and the maximum rotation indicators must be reduced to 15 thousand, you need to rotate the screw marked with the letter H. Rotate it gradually, slowly in the direction of the opposite movement of the clockwise.

Reducing the revolutions to the optimal value will reduce the risk of engine operation for wear.

Features of the Husqvarna chainsaw

Despite the fact that the ideal chainsaws are not created and it is unlikely that anyone will succeed, this Swedish company strives for the perfection of the design and increase the power of its models. The entire Husqvarna saw line is characterized by pleasant improvements that significantly facilitate the work of its owner.

Such positive options include:

  • Using the “sucker” button (primer ”(primer) for the convenience of launching the internal combustion engine;

  • on the side of the chain tension mechanism;
  • ecologically clean and powerful X-Torg engine;
  • vibration reduction system;
  • the mechanism of forced lubrication of the chain by means of a hole in a driven star;
  • Air Injection Air Centrifugal, which allows you to change the filter less often;
  • Universal maintenance and repair key.

Ignition adjustment algorithm

The ignition on the trimmer is adjusted quite simply.

    Remove the casing from the engine by unscrewing all the bolts holding it. For example, on the Patriot gas.cave (Patriot) PT 2540, to remove the casing, you need to unscrew the air filter housing, and remove it with a flat screwdriver from the latches. After that, the plastic case will easily remove.

  • Unscrew 2 bolts using a screwdriver (it is not required to be completely twisted), holding the magneto.
  • Turn the flywheel so that the magnets are upstairs.

Further, in order to properly set the best gap with a flywheel and coil, you can use a regular visit or a calendar. If you have neither one nor the other at hand, then to configure the ignition, you can use a sheet of A4 paper by curling it 2 times (as a result, you will get 4 sheets thickness). This thickness will be enough to get the optimal gap and adjust the ignition. Insert a business card or paper between a coil and magnets.

Adjust the carburetor yourself

Gas braids, like all gasoline garden tools, are not easy to serve. You can and should be repaired, set up on your own. For example, homemade carburetor adjustment using a brush. The point is five minutes.

Board.cutting carburetor is a knot in the energy system. In it, as in any carburetor, there is a process of mixing air and fuel (gasoline) for further supply to the engine cylinders.

The main thing in this process is the correct proportion of fuel and air, which they regulate the carburetor.

The grid has only two problems with this element:

To determine the cause of the breakdown, remove the fuel filter cover to eliminate the leak. If dirt has accumulated on it, flushing with gas or purging will help.

For visible damage, the mesh filter should always be reinstalled. There may also be damage to the fuel line (check this element for repair).

In most cases, the carburetor does not work due to blocking. Use rinse with acetone or the same gasoline.

Filling the components of the carburetor with compressed air is an acceptable and convenient repair practice.

The housing of the throttle, ligaments of the parts of the carburetor, inlet or exhaust pipe. All these details are sealed. You can probably check this in a primitive way. cover the problem area with soap spots.

The basis of carburetor gasoline braid is the aluminum case. Contains a diffuser (hole with internal contours). Air is blown through the hole. Oxygen (air) consumption depends on the cross.section (through hole) of the diffuser.

The diffuser is equipped with fuel channels. Of these, fuel is collected by air flow.

The throttle valve determines the amount of air supplied, and the engine power directly depends on it.

ignition, husqvarna, mower, diagnose

The fuel is absorbed into the carburetor system using the pump (its membrane). Then it passes through the fitting in the carburetor. Then the liquid moves through the intake and exhaust valve of the pump. Filtered on the grid. The needle valve moves into the diaphragm chamber.

  • Air supply to the pipe is carried out through an air partition (damper). The partition controls the intensity of the air flow.
  • The fuel supply system should be narrowed by a diffuser to increase the consumption.
  • Gasoline through a float chamber and a tapering pipe of the nozzle. The float chamber regulates the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the pipe with narrowing it is already low. Due to the drop in pressure, the fuel enters the nozzle.
  • Air flow acceleration facilitates the transfer of fuel (gasoline) and its spray. The result is a fuel mixture of the desired proportion or density.
  • The air-fuel mixture enters the engine cylinder through the fuel pipe.

The level of air density in the system depends on the area of ​​the shutter in the open air. The wider the valve is, the greater the fuel consumption and performance.

Simply put, adjusting the carburetor on the brush creates the optimal fuel mixture due to the correct air supply.

Before installation, thoroughly clean the filters in accordance with the service instructions.

Make the carburetor itself, further adjustment of the bush cutter is carried out by adjusting the screws. There are three of them:

Right (l). Fuel mixture adjustment at low speeds.

You need to find the maximum idle speed. To do this, slowly turn the screw (l) to the right and left.

To adjust, turn the screw for a quarter of turning clockwise.

Lower part (t). is responsible for the operation of the engine at idle.

For the correct regulation of idle, the following is typical:

  • stable operation of a cold engine;
  • The speed of rotation of the hot engine is not overstated;
  • large head of a trimmer for grass;
  • Stable engine operation when changing positions (sharp rise or lowering a knife).

Left (n). adjustment of the mixture at high speeds. (The screw was last resolved).

The left screw (n) determines the general control of maximum speed, engine power, temperature and gas flow.

A trimmer for carburetor grass with the last screw is as follows:

  • Open the throttle to complete, giving full gas. Turn the screw clockwise until the speed falls (in this case they are oriented to the ear).
  • Turn the screw as slowly as possible counterclockwise until the engine starts to work uneven.
  • Then turn back slightly, barely audible, stable, smooth work.
  • For a more clear use of skills, it is more convenient to consider the work of an experienced user:

It is interesting that from the point of view of the author of the video setting (its correctness) is determined by the color of the candle, and not just the speed and stability of the engine.

Correct tuning the carburetor with your own hands in this case. burn the fuel mixture without a residue, the color of the candle should be light brown.

How to adjust a carburetor for a trimmer for grass

1) Right screw. regulates the enrichment of the low.speed mixture (initially adjusted): Find the maximum space, slowly turning the right screw to the right and left. Then turn this screw and turn it counterclockwise. Note: at the Husqvarna plant, the right screw was completely unscrewed (0.5 turnover). It looks at 11 hours now.

2) lower screw. Husqvarna’s idle stroke (if necessary): rotation of the screw clockwise increases the speed of idle, reduces it counterclockwise. The idle control is considered correct when: 1. cold engine at idle stably; 2. The hot engine has not a high.high idle speed; 3. A sufficient supply of rotation remains until the rotation of the three.dimensional head; four. The engine is stable in any position (for example, with a sharp lowering knife). Note: on the manufacturer (Husqvarna), the idle screw from the fully tightened was unscrewed at 8 full revolutions and “2 hours” (now it remains). The recommended blasting speed of the Husqvarna gasoline engine is 2.900 rpm.

Следующие показатели являются регулируемыми:

The purity of the mixture should be adjusted if the smoke formed during fuel combustion is too gray and the engine smokes. An additional sign of improper adjustment of this carburetor indicator can be a “rough” sound made by the engine in a groovy state.

The speed is standard. It should be between 8500 and 8800 with the maximum pressure button of compressed gas (average data are indicated. It is recommended to read the instructions attached to the tool to determine the number of revolutions necessary for the work of your model). Tachometer is recommended for maximum accuracy.

Idle parameters are adjusted if necessary. The thrummer head of a trimmer for grass does not work at idle. If the rotation is observed, the adjustment is performed until the head stops rotating.

This carburetor installation method is suitable for all http: // Stroyteh models.COM/Category/Motokosy-Trimmery/. By the way, there are inexpensive models, and the assortment is quite wide. Many of these models are sold at a discount, so you can save money.

Entricons identification and repair of artisans

Petrol. The most important tool for those who want to support their land in order and beauty. This type of equipment processes almost all types of grass and weeds. After using this device, a piece of earth overgrown with weeds will look right.

However, any tool is inability. Sooner or later, this clearly gives rise to various problems. How to solve problems with gasoline scales, this article will tell.

1 common reasons for the malfunction of the lawn mower

Before moving on to the list of common reasons for the breakdown of the lawn mower, we note that very often inexperienced owners of lawn mowers do not know, for example, which gasoline ratio should be poured to the fuel tank, which gasoline is best added to the machine, how much oil is poured into gasoline, and t. D.

Some also do not know what lubricant to use for gearboxes, how to sharpen a disk or knife and many other nuances. For these and other reasons, unfortunately, in many cases, equipment breakdown may occur, including trimmers for grass and lawn mowers. Users simply do not give a damn about equipment at the proper level.

However, there are a number of general reasons due to the specifics of the functions performed and other external and internal factors that lead to their refusal:

  • The cutting cord is not served and does not break too quickly. This is due to the absence of a mowing fishing line of hair growth or confusing the braid to the brush in the coil;
  • The engine will not start. Inexperienced users will not always be able to start the device on the first attempt, since the “Start” button is turned off. But there are other factors: a clogged air filter; The gap of the candle is not installed or does not work; A gasoline carburetor can often overflow the fuel mixture; insufficient fuel injection;
  • Often, brush machines do not develop speed, which can be caused by four factors: clogging of an air filter, clogging the shaft of cutting reel with mowed grass, incorrectly adjusted carburetor, poor fuel, which is poured into the tank;
  • The engine does not work at idle. If the engine works on its own, but stops at idle, there may be three reasons: clogging of the air supply filter; the carburetor is not adjusted; poor gasoline or oil is used;
  • such a problem as the lack of a spark also arises regularly. Reasons: strong clogging, broken candle, breakdown or contacts of armed armor were oxidized.

one.1 Elimination of malfunctions

Rupture of the cord occurs regardless of the quality of the coil in the coil. To fix this confusion, it is enough to rewind the cord if it is confused, or rewind the new one if it is absent.

How to start a brush if the engine does not start? Make sure the Start button is turned on that a sufficient amount of oil is supplied through the supply button or that gasoline is refueling into the tank. If the engine is still not launched, rinse the gas filter (sometimes it should be replaced if a lot of clogging is detected), check the correctness of the spark plug and clean the air filter.

It did not help? Set the carburetor air damper to position C, this solves the problem of filling the fuel. In the case of the “resistance” of the engine, just drain all the fuel from the system and pour new, making sure that it is of good quality. The implementation of all these processes solves the problem of engine starting in 80-90% of cases.

If the engine refuses to work at idle, first adjust the carburetor and rinse the air filter of the unit, which in most cases solves the problem. If this happens again, most likely you poured poor fuel into the fuel tank, then squeeze it and pour the new.

How to run a bush and make it work if the engine does not rotate and it stops? First make sure that the cutting shaft does not clog grass and weeds. If the shaft is in order, rinse the air filter or replace it with new ones, if the first seems too dirty. By the way, the air filter should be washed with detergent and gasoline, which makes the gasket more flexible and prevents the drying of the material.

If, after these procedures and pressing the bureau starter, the brush stops again, then the problem is that the carburetor is incorrectly adjusted. Read the last section of this article to find out how to adjust the carburetor on the brush.

If there is no spark, put a spare candle to understand what is the matter. When replacing the sparkling candle with the correct gap, there is also no spark, the fact is to equip a braid. In case of malfunction, the repair of the brush begins with the check of the wire leading to the candle.
