How to assemble a starter for a trimmer for grass correctly
If the trimmer engine for grass does not start or stalls immediately after starting, when overheating or during the functioning of the device, extraneous noises are heard and vibration is clearly felt, it is important to perform a visual inspection and identify a non.working node
To optimize preparatory measures before repairing, a simple diagnosis should be carried out and checked in stages:
- the presence of fuel in the tank and lubrication in the main nodes;
- serviceability of the spark plug and its performance;
- the purity of the fuel and air filter motorcycles;
- Cutting of the exhaust channel and the device’s saepun;
- The quality of the used fuel and lubricants.
To determine the functional performance of the ignition of the lawn mower, you should determine whether the candle works by testing the appearance of a spark in contact with the body of the functional device.
The spark plug itself can be changed to a new one, after driving the candle canal, if necessary, the old element is also dried, cleaned with special devices and returned to place.
Starter repair work
Problems in the work of the starter may not ensure the launch of the tool. That is, after the cord is stretched, the chainsaw does not start to work.
Family Brovchenko. Springing a spring in a hand starter of a lawn mower.
How to install a spring in a hand starter for a benzo-trimer? At home it is possible to do it. to me.
Before you repair the starter, you need to prepare the tools with which work:
- set of screwdrivers or a special tool that is attached to the manufacturer complete with the tool;
- a rope that will be used as a replacement of a broken cord if necessary.
A large amount of black carrier on the spark plug indicates the violations in the engine operation.
Before proceeding directly to the repair of the starter and clarifying the causes of malfunctions, it is necessary to remove it from the tool body. To do this, unscrew several screws holding the side cover to which the starter is attached. Problem with the installation of the Stihl 38 lawn mower starter. This is done by a screwdriver or a specialized tool.
After the lid is unscrewed, it is turned over and examined. Next, unscrew the screw with which the starter is fixed. After that, the clamp and the spring are dismantled to carry out smooth launch. Now for removing it is accessible to an affordable pulley on which the cord is wound. After the knot on the rope is unleashed, it can be pulled out of the pulley and replaced with a new. Provided that the loss of performance of the starter is associated with the cliff, this may be enough to eliminate the breakdown. Launcher. However, the rest that make up this element of the chainsaw should be carefully examined.
When examining the components of the starter, the following malfunctions can be identified:
Most often, damage to the smooth starting spring occurs from the end where it is visible when disassembling the case.
- The pulley can be damaged. It is possible to have cracks or tears, as well as damage on the back. As a result of these problems, the tool cannot perform work.
- Damage to a smooth launch spring. The device of the starter of the Lawn mower Interskol ICD 4325. In this case, it can be mechanically faulty both the spring itself, and there are defects in the place of its fastening. The weakest place of this element is precisely the fastener and the tip of the spring, which is inserted into it.
If faulty or partially damaged starter parts are detected, they must be replaced by new. In this case, new elements must correspond to the repair model of the saw.
After the repair is completed, it is required to properly assemble the starter.
The pulley is installed on top of the spring. At the same time, it is necessary to check how much they clung to each other. During the repair, it is necessary to perform the pulley winding. This must be done in such a way that when rotation, he pulls the cord into the starter. It is enough to make 3-4 turns to give the required voltage. Replacing the starter of the lawn mowed. Previously, the rope is threaded through the hole in the chainsaw cover.
How to start a lawn mower properly?
Regardless of the type of action, there is a strict order that must be observed, that is:
Inspection and verification
Any trimmer malfunction for grass can be a serious danger.
Poorly tightened bolts fixing the clutch bell to the engine can lead to rapid abrasion of clutch pads, and any leak of the fuel system often leads to ignition and burns or fire.
The weak tightening of the gearbox bolts can lead to the fact that the rush shaft bar will jump out of it and the trimmer for the grass will stop working. Weak tightening of bolts fixing the handles can lead to involuntary lowering the shaft and damage to the cutting tool.
Therefore, before any launch, you need to at least briefly inspect the device in search of defects. This is especially true for any first launch, it does not matter, after the purchase, or after storage. During the working starts, it is permissible to inspect only the fuel system for leaks.
One of the most important stages of verification before any launch is to determine the amount of lubricant in gearboxes and a drive shaft, for which you need to disassemble a trimmer for grass and remove both gearboxes from the shaft.
So you will evaluate the quantity and condition of the lubricant not only from the side of the gas station, but also in the area of contact of the shaft bar with the gear of the gearbox.
Also, once every 2-3 weeks, check the amount and condition of the oil filled into the crankcase of four.stroke engines, if the device will work with a low level of oil for a long time, then the probability of jamming of the crankshaft is likely.
The gas station is fuel
This operation has to be done after purchasing and winter storage, as well as during the termination of work caused by the production of gasoline. Four-stroke engines are seasoned with pure AI-92 gasoline, and two-stroke with a mixture of fuel and special oil, which we talked about here.
Remember, if you refuel a two.stroke trimmer for grass after winter storage, be sure to drain the old fuel from it, because it has already lost the lubricant, so the crankshaft bearing and cylinder.piston group will work without lubrication.
Launching a benzotrimer
Regardless of the type of launch, there are 6 actions that have to be performed always:
- fuel pumping;
- the transfer of the air damper to the “Launch” position (“Closed”, “OFF”);
- the transfer of the switch to the “inclusive” position (“VCL”, “on”);
- pressing and fixing the gas key;
- the jerk of the starter cable with the choice of free move;
- transfer of the air damper to the “work” position (“open”, “on”).
The first 3 points from this list can be performed in any sequence, but you can pull the cable of the air starter only after them. Neglecting fuel pumping will lead to the fact that a hand starter’s cable will have to pull the moving piston of the motor to pump a sufficient amount of air that sucks from the carburetor fuel.
The neglect of the air damper will lead to a strong rethink of the mixture, which is good for a running engine and extremely bad for starting, because such a mixture is well ignited only inside the heated cylinder.
After the air damper is transferred to the closed position of the incoming air, it is not enough to operate the motor at idle, so click and fix the gas key (accelerator, engine speed regulator). The button for turning on/off the motor blocks the operation of the ignition system, so before starting, transfer it to the “inclusive” position.
If you do not transfer the switch to the right position, then the voltage will not come to the candle, which means there will be no spark that ignites the mixture in the cylinder.
After the engine works, transfer the air damper to an open position, because the highly re-enriched mixture is good for starting, because it is flammable even in the cold cylinder, but due to lack of air, the fuel does not burn out completely.
An attempt to mow grass with a closed air damper will lead to a sharp drop in the power of the motor and a strong heating of the valves, so the long work (tens of hours) leads to the gap of the valves or damage to the laying of the cylinder head head.
If the motor does not start or works incorrectly
The reasons that the motor does not start with a two or four jerks of the manual starter cable can be:
Most often, this is due to the incorrectly executed trimmer for the grass, when the procedure is violated or some important point is not executed, so the launch is quite correctly carried out and the motor will work. If the mower is poorly started after storage, then most likely, old gasoline is exhausted, so it is enough to change it.
If the trimmer for the grass was not served for several seasons, then the poor launch can be due to dirty air or fuel filter, so it is enough to rinse or replace it.
If all actions are performed correctly, but there is no positive result, contact the workshop or independently diagnose or repair.
Assembly of a motorcycle starter
During maintenance and repair of the starter, it is important to properly collect it. as if the assembly of the device was made by the manufacturer
Any incorrectly installed details will not allow you to fully use a trimmer for grass or braid.
- After winding the spring, turn the coil and install it so that the second spring hook will return to its place. There are technological windows on the coil to control the correct installation of the spring.
- Place the starter’s pulley and make sure that one of the spring hooks enters the groove located on the starter cover.
- Insert a spring and washers on the sides so that the spring does not wash the plastic compartment in which it is located. If the spring is broken and the other is not, an additional washer is put in its place.
- Insert a cup of antennae into the deepening of the coil.
- Put the coil in place, tighten the bolt to the end, but without fanaticism.
If you do not protect the compartment with washers from the main spring, the compartment where it moves when unscrewing and unscrewing the starter cord, the coil often snaps when trying to launch a gasoline trimmer for grass or a bush. The weakening of the coil bolt will lead to its loss.
Information on how to assemble a starter for a trimmer for grass, watch in the video.
The device of the chainsaw starter
Almost all leading manufacturers of chainsaws complete their products with starters of a similar principle of action. It is no coincidence that specialized stores offer universal designs of starters that are equally successful for both Stihl, Husqvarna, Makita chainsaws, and for Chinese semi.official fakes under the named brands. Only starters of domestic production (forester, Urals and a number of others) have some features only.
The principle of operation of the starter for the chainsaw is as follows. A handle is installed in the groove of the case, through which the cable is missed. If the handle is sharply lifted, the cable is stretched, and introduces the drum of a ratchet that transfers the movement to the drum with the slots provided for the shaft. In this case, the crankshaft makes several revolutions, and the working mixture in the space between the piston and the cylinder head is compressed. Accordingly, when lowering the handle, the contact between the ratchet and the slots is lost, and the shaft stops.
With an increase in the volume of the engine, the required amount of fuel-air mixture required for its subsequent ignition is also growing, so the number of jerks for the starting cable for large power saws increases. Therefore, in order to accelerate the return of the drum, baked return springs made of steels with high elastic properties are used.
The relief of the launch of the chainsaw is realized in the following ways:
- Preliminary enrichment of the working mixture, for which there is a special damper in the design of the carburetor.
- By installing an automatic decompression valve, which provides a decrease in the working pressure in the chainsaw cylinder.
- By installing an additional spring, which during the movement of the cable facilitates the spinning of the crankshaft.
- The presence in the design of some chainsaws (for example, Partner S, Maxcut, etc.) the primer. the pump that provides preliminary pumping of the fuel.
Repair of a trimmer for grass replacing the starter spring
Removal of the starter of the starter of the lawn mower with your own hands. Often fails a spring that is easy to change in home criteria. It is necessary for its replacement, a cross screwdriver and a hexagonal key that comes with a mower. Device and mechanism of the starting mechanism- ordinary. Disassembly and assembly is not very difficult. Trimmer Reparatur Starter
Replacement of the starter on the trimmer
How to repair a starter on a trimmer with your own hands. How to disassemble and assemble a starter, wind a spring and change the cord.
Installing or replacing the starter of the starter motorcycles, motorcycle, trimmer for grass
But what to do if everything is in order with the rope, and the coil (pulley) of the starter is not wound? We will see this issue step by step on the example of the starter of the ADA Grounddrill gasoline motorized car, having a pulley with 2 metal antennae for 2 hooks.
In the case of other types of manual starters of an identical design, which are extensive used in gasoline motorcycles, trimmers and motorized carriers, the entire starter repair process will look similarly, differing only in some aspects.
Starter repair: disassembly
Unscrew the screw with which the pulley is attached to the starter cover. We take out the antennae, spring
We pull the pulley itself carefully so that the spring does not bounce into the face. Even with the most accurate disassembly, it usually immediately flies out of the coil and sharply turns into a long iron strip or twisted by rings
Gently remove the snow.white coil of the starter. do not be wounded up by the spring!
If the spring burst or one of its hooks-stalks broke, then it will not work to repair the starter and it will not work out-it is required to replace the spring. In order not to waste money to buy a new starter, you can find on sale only her.
In case the starter spring simply fell off, t. e. One of the hooks came out of the hook, enough to stick it, as needed, slightly tightening the hooks more tightly (just do not break off!) Install the spring with an external hook in the groove of the pulley and begin to twist it, immediately holding the spinning of the coil with your fingers and preventing it from jumping out of there.
Clutching the spring to the pulley, with radial movements we wrap the spring inward
The first time to stick a starter spring may not seem so easy, but everything comes with experience. Slightly practice, you can freely wrap the spring into the pulley maximum per minute.
The winding of the starter spring is made. It remains only to assemble the starter and take the spring to the appropriate value
How to repair a starter on a trimmer
One of the key components of shieldcorrosis is a starter designed to facilitate the start of the device engine. Like other parts, it is periodically destroyed. In this case, there are two solutions to the problem: repair the starter of the trimmer for the grass or replace it completely. The second option is simpler, but more expensive. In addition, the necessary part must first be found on the market, since various starters are used for different models of shield. If you have free time and a screwdriver with an appropriate tip, you can restore the functionality of the device, if you know how it works, the malfunctions are typical for it and how to correct them correctly. All this is in this material.
Spring coagulation. Not an easy procedure. Not everyone succeeds install the part to the place for the first time, so do not be upset if it fails. You need to repeat attempts until the action is successful. If you wish, you can look on the Internet where masters tell in detail and show how to easily and quickly perform this operation.
To wind the spring, you need to place the bend in the groove, and then, rotating the coil, carefully lay the part along the inner diameter of the spool. In this case, the spring needs to be kept constantly with your hands
Briggs & Stratton Riding Mower Engine Starter Motor #693551
If it is not fixed, the part slides and jumps out, then the winding has to be done again. With proper execution, the spring sits firmly on its seat.
Replacement of the cord
To replace the element, you need to find the coil of the hole in it through which you pass the cord, and then tie the knot. Next, you need to wind the coil with a spring, having completed a few turns.
For example, if the cord wrapped in a circle six times, then to tighten the spring, you need to turn the coil counterclockwise six times. After that, it remains only to draw a rope through the hole and fix the handle on the cord.
The process of disconnecting the starter
An uncomfortable location is one only difficulty in dismantling. All basic operations are performed quite simply. No specific tools or special professional knowledge are required.
You need to remove the starter with the ignition disconnected and act in the next sequence:
- First you need to disconnect the terminal of the battery mass (removed);
- For convenient work, remove the battery with the holder;
- Next, it is necessary to remove the protection at the bottom of the engine (if it is installed), free access to the starter is opened;
- Unscrew the clip of a set of suitable wires;
- Unscrew and remove the wire holder from the relay;
- Unscrew the bolts of fasteners;
- Remove an absolutely free unit from the bottom of the car.
Now the repair or replacement of the starter, which is made in the reverse order, can be carried out.
The main malfunctions of the starter of the trimmer for grass
Find the reason for the breakdown of the starting device is easy. There are several main options:
The designated details are shown in the photo below.
It may happen that the starting mechanism will be broken by the case. The consequences will turn out to be deplorable if the ragged rope is wound around the flywheel of a working internal combustion engine: then the spring bursts, the pulley will tear off. But such cases when a complete substitution of the starting node is required, very occasionally occur. Almost always, to fix the mechanism, enough put
Parsing the starting node
In order to establish new details of the incorporation broken in the subsequent sequence:
- spin a screw with a screwdriver, fixing the pulley with a starter lid;
- take out a spring and antennae;
- Remove the pulley neatly (it is necessary to unscrew your head or work with all this, putting on your glasses and gloves earlier);
- determine why the starting mechanism has broken;
- If the spring was actually destroyed by one hundred percent, then it is replaced;
- When the spring exits from the hook, it is installed in the original place, bending the antennae before that (the photo shows the styling process);
After the spring plate is installed inside the groove, carefully make it twisting. To change the spring, you should work intently and carefully: it can, under the influence of the effort caused by the installation of it in place, to break through
Even if you carefully remove the video, then the spring strip flies very rapidly from the coil and can injure the hand with its sharpened edges

How to change the starter cord?
It happens that in the impossibility of starting a starter is not a spring to blame, but the cord itself. He can seize or completely break. Dismantling the starter of the lawn mower or trimmer for grass is universal in its steps.
- Remove the starter block from a trimmer for grass or lawn mower.
- Unscrew the main bolt holding the handbrake.
- Pull the coil and melt the remains of a worn cord from it.
- Unscrew the knot on the handle of the cord and pull its end from it.
- Untie the knot at the other end (at the beginning of the coil) and remove the old cord. The nodes that have become tight are unleashed with pliers or ticks.
- Tie a knot on one of the ends of the new cord, prone it through the hole at the beginning of the coil (closer to its axis).
- Shin a few turns of a new cord to the coil. If it is long, then cut the excess.
- Season and soak the spring tensioner (if it starred) and spring.loaded elements in the correct sequence.
- Put the coil in place and take the free end of the cord to the outlet of the starter and in the handle.
- Install the starter block in place.
Twist the starter by the cord, start the engine of the lawn mower or a trimmer for grass. The larger and more powerful the engine, the more cord jerks will be required when starting, the norm is no more than 7 times. The result is a quick and smooth launch of the motor, the readiness of the unit for work.

Replaced the rope of the starter of the motor block MTZ 09N, installed on the engine, the starter freely rotates the crankshaft, which could be?
Most likely the problem in the ratchet mechanism of the starter, it can be said exactly after disassembly.
Consider the device of a hand starter on the example of a walk.behind tractor with a similar problem.
In the presented walk.behind tractor, in addition to a non.working starter, there is a problem with the casing of the flywheel, the fasteners for the starter are simply rotten. In order to remove the starter, you need to unscrew three bolts. Our starter is removed, we will have to replace the casing first.
HOW-TO Replace A Lawn Tractor Starter
Когда стартер снят и находится у вас на столе следует открутить крышку катушки она крепится одним болтом.
Remove the coil and check the return spring, there should be a hook inside the spring that clings to the housing of the starting device, the second hook enters the sprout that enters with the gearing with the coil body. On our coil, both hooks are straightened and not suitable for further operation, we change the spring.
We check the emphasis on the body of the starting device, it should be even without production, this is important for reliable hook hook
Cut the starter rope of the desired length and melt the edges in order to easily tuck it into the housing and coil of the starting device.
We check the operation of the springs of the ratchet mechanism, check the springs themselves, the mobility of the petals in the coil. The springs should press the petals inside the coil of the starting device.
We start assembling the starter. We set the spring in the coil of the outer hook of the return spring cling to the coil body. Lubricate and insert the coil into the housing of the starting device, so that the inner hook hook enters the hook with emphasis on the starter case. We fix the starter case and make about five full revolutions of the coil counterclockwise while on the last turnover you need to combine the hole on the coil with the hole on the starter case.
You need to do all this very carefully, the return spring can get out of the cloth and injure. After the return spring is cocked, you need to lock the coil and season the starting rope by passing it through the starter case and the coil and the coil.
We tie the starter rope with a regular knot inside the coil, insert the second end of the rope into the starter handle and make the knot.
Install the coil cover, put a clamping spring between the coil and the lid, put the lid, apply an adhesive-mixture on the bolt and clamp.
We check for the rattles of the ratchet mechanism to come out simultaneously quickly, the coil should spin smoothly and easily.
Install the starter on the engine, to fasten the starter, you need to use special bolts. Unfortunately the bolts from this starter are lost.
The starter works great, as can be seen in the video, a similar starter works not only on Honda engines, but also on old Soviet.
Other malfunctions and their causes
In this section you will find recommendations that will help you determine and eliminate the problem if the trimmer for the grass has stopped starting.
We have collected here the most common malfunctions, as well as a list of possible reasons that lead to them.
This will help you quickly conduct a check and determine the real reason why the lawn mower stopped starting.
There is a spark, and a candle is dry
If you checked the spark with a discharge and it pierced a distance of 1 cm, then change the candle, and if this does not help, look for why the fuel does not enter the combustion chamber.
After all, if it had been received, then the motor would work, and with an excess of fuel, the candle would be wet.
If there is a spark, and the candle of the lawn mower is dry, then to establish the cause, do the following:
- Check the fuel hoses and filter;
- Check the primer valve;
- Check if the carburetor is clogged;
- Look for air leaks.
Having discovered the problem, repair or replace the damaged part.
There is a spark, and the candle is wet
If the discharge showed that there is a spark of sufficient power, but the candle is wet, then there is too much gasoline or too little air in the combustion chamber of the lawn mower.
These are the possible causes of such a malfunction:
- faulty candle;
- exhausted gasoline;
- Dirty air filter;
- a layer of soot on a candle;
- Air damper jam.
Conduct diagnostics as described above, then eliminate the problem.
The candle is wet
If there is nothing to check the spark, then to all the possible malfunctions described in the previous section, add the problems of the ignition system. Then conduct a full check of all the trimmer systems and devices for the grass, because the reason may be anywhere.
Do not start “on hot”
If a benzotrimer is poorly started or not started “on hot”, then possible reasons:
- Dirty air filter;
- the ventilation holes from the hand of the manual starter are clogged;
- The wrong gap between the flywheel and the ignition coil.
Check all systems and details as described above, and also adjust the gap between the flywheel and the ignition unit.
Not starting “on cold”
These are the possible reasons why the benzotrimer is poorly started or not started by the “cold”:
- fault of the air damper drive;
- air leakage;
- Primer faulty;
- too much gap between the flywheel and the ignition unit;
- scored sapunes;
- Piston rings lay down.
Check everything as described above, then eliminate the cause.
Badly starts in all modes
- Dirty Sapun;
- old fuel;
- air leakage;
- dirty candle;
- The wrong gap between the flywheel and the ignition unit.
Check everything as described above, then eliminate the cause.
There is no spark
If there is no spark, then the possible causes of the malfunction are the following:
Starts and stalls immediately
Check everything as described above, then eliminate the cause.
Below we bring to your attention several videos about the reasons why the lawn mower is not started, and about the ways to eliminate them.

Starters for lawn mower. device and installation features
Repair of the starter of a gasoline trimmer for grass may be required suddenly. Here you can solve the case with 2 methods: change the broken part or change the entire node. The latter option will cost more. To repair the device on their own, only a screwdriver with a suitable tip will almost always come in handy from the tools. Repair work will not take extra time and do not even require special knowledge. It is enough to know the device, the mechanism of work, aspects of the assembly-disassembly of the starter on the trimmer to achieve a good good result.
The device and principle of operation of the starter on the trimmer
The gasoline engine is, in principle, the main part of the motorcycles its power lies in the range of 0.5-2.5 liters.With. The movement from it is transmitted by the shaft located inside the hollow bar, and then through the gearbox, consisting of gears, already a fishing line or a knife (working body).
Also, the lawn mower has the following elements:
- protective casing;
- a belt designed for ease of use of the device;
- Starter serving for launching a gasoline internal combustion engine.
All parts of the motorcycles are presented in the photo further.
The starter on the trimmer is an integral part, which performs the engine starting into operation. It is shown separately in two photos below.
The starter mechanisms of various models of the benzos work according to the same principle: during the launch of the ICE, the protrusions marked in the photograph above the number 1 are included in the hook with dogs 3. When the engine begins to work, they return to their previous position due to the effects of centrifugal. Similar role is also played by wires 2.
The process of returning to the initial position of the elements of the mechanism occurs due to the presence of a spring screwed around the axis. It unfolds when the rope is pulled. After releasing the cord, it is drawn and winding due to folding the spring. During the launch of the ICE of the lawn mower, the triggering mechanism turns its shaft until it starts to work (starts).
To date, gasoline motorcycles are equipped with two types of starter mechanisms:
The first option is much more common.
The starter on the trimmer can function without breakdowns for a long time. It is impossible to unambiguously indicate the deadline. Everything is determined by the initial quality of the device and compliance with the rules of handling it.
How to prepare for winter storage?
To prepare a trimmer for grass for winter storage, do the following:
- Carefully clean the entire surface of the trimmer for grass from the remains of grass;
- Remove the cutting tool and grease all the metal parts with a thin layer of engine oil or treat with silicone spray;
- Disconnect the drive shaft from the engine;
- Remove both gearboxes;
- Lubricate all the slots of the gearboxes (including from the cutting tool) and a drive shaft rod with any engine or transmission oil, including the development of the engine of the benzotrimer, if you plan to store the device assembly, or any thick lubricant, if separately;
- Install the gearboxes on the drive shaft (if required);
- Connect the engine and drive shaft (if required);
- Install and adjust the handles (if you plan to store them on a trimmer);
- Pour all gasoline from the tank and tighten the lid of the fuel tank, then start the engine and wait for its stop;
- After cooling the engine, unscrew the candle from the engine;
- Pour 1-3 ml of pure motor oil into the combustion chamber, then screw the candle in place and smoothly pull the hand starter cable so that the engine will make several revolutions and evenly distribute the oil;
- Rinse and blow, or replace the air filter;
- Rinse the fuel filter (if it is installed on a trimmer).
How to use a gas toss correctly?
The only way to extend the service life of a trimmer for grass is its proper operation. Unfortunately, some of the manufacturers are not interested in the too long service life of their products, so part of the rules that help to more carefully spend the resource of the apparatus are not included in the instructions for the operation of the benzotrimmer.
For this reason, we recommend carefully comply with all the recommendations of this article, even if they are not in the operating manual, because we made recommendations on the basis of:
- the experience of operating many owners of devices that they were divided on the pages of various forums;
- tips of those who are engaged in the repair of motorcycle;
- Recommendations from the operating manuals of trimmers of the most expensive and high.quality brands.
Since the operation of a trimmer for grass implies not only mowing grass, but also many other actions, we divided it into the following topics:
- The engine is running.
- The choice of revolutions.
- The direction of the mowing.
- Choosing clothes and protective equipment.
- Security measures.
- Transportation and storage.
The engine is running
Despite the fact that the engine of the newly purchased trimmer for the grass is already driven and you can immediately proceed to the mowing of the grass, avoid maximum speed for the first 3-5 hours, because the final grinding of the parts of the cylinder piston group occurs.
If we allow the motor output at maximum speed, then there is a high probability of the appearance of stray on the walls of the cylinders, and this will lead to a sharp drop in the efficiency of the motor, and will also greatly reduce its resource.
The choice of revolutions
The maximum torque of the motor appears at revolutions corresponding to 2/3 of the maximum, and the greatest power appears at revolutions corresponding to 3/4 of the maximum. Therefore, the most effective trimmer for grass mows grass in this range.
The exit to maximum turns slightly reduces power, so during the mowing of grass, focus on the sound of a trimmer for grass and evaluate the speed according to this parameter.
If the load is too high and the speed of rotation of the shaft of the power unit is reduced, add the gas using the corresponding key on the working handle.
As soon as the load decreases and the speed increases, press the gas key less to return the speed of rotation of the motor shaft to optimal value.
If before you have never used a motorcycle, then until the completion of the run.up, mow only low and non.thick vegetation, which a trimmer head with a fishing line easily copes with. After completing the running.in, the engine will cease to be afraid of maximum revolutions, and you will acquire a sufficient skill to control the motor by ear.
In addition, avoid the long operation of the motor at idle, because because of this, the lubrication of the crankshaft bearing is deteriorated, which can lead to its overheating and jamming.
The direction of the mowing
When working with a motorcycle system in the maximum capture mode, move it so that it goes against the direction of rotation of the cutting tool.
In this case, the knife or disk will repel the device from a possible obstacle, so the trimmer for the grass will not jump out of hands.
In addition, with such a movement, a knife or head is thrown back in front of you, so you will better feel the resistance of the mowing of grass, which means avoid too fast movement and caused by it:
For most trimmers, the right direction of mowing grass is movement from right to left. When moving in the opposite direction, the trimmer for grass continues the mowing of grass, so the probability of a reverse blow increases, due to which the device can be very jerking. Therefore, when moving in the opposite direction, try to capture smaller grass to reduce the load on the device and the probability of a reverse blow.
The choice of maximum maximum capture mode is especially important at:
In addition, when pruning trees, try not to raise a cutting tool very much, but also not to turn it perpendicular, because this can lead to a violation of the carburetor.
This requirement is not relevant only for trimmers-crossbars, whose carburetors work equally effectively in any position.
Choosing clothes and protective equipment
A trimmer for grass is a device of increased danger, so to work with it you need to choose the right clothes and protective equipment.
When going to mow grass, put on only clothes without any straps and fringe, which can tighten a rotating cutting tool.
If you put on shoes with laces, then take measures so that they do not untie. If you have long hair, then limit their mobility by putting on a hat or tied with something. Be sure to put on glasses or a protective mask, because it is likely that the grass cuts will not where it should and falls into the eye.
