How to grease a trimmer for grass with oil

Today, many stores sell tubes with lubrication in many stores, so people often have the question “how to lubricate the part?””. To complete the most important procedure, you can take syringes and try to independently gain the required amount of substance into it. After several attempts, the operation will certainly take place very easily and quickly.

To care for the units of the mechanism, lubricants of different consistency are used:

  • Semi.liquid. Such compositions contain a variety of additives and additives.
  • Plastic. Are the most universal option. Most often used for gear and screw gears.
  • Solid. Plate suspensions in its original state.

A special gear composition belongs to the semi.liquid system.

Popular is a grease for a trimmer for the grass “Stihl”. Thanks to the special composition and components, wear is significantly reduced and resistance to corrosion increases. The main properties of the lubrication of this brand are:

STIHL lubricant is suitable for black cutters and trimmers, as well as for all transmissions with a closed case.

Characteristics and features of lubricants for bells

When servicing any manual tool, where there are mobile parts, a lubricant is used that has the following characteristics and features:

  • It should not have solid particles that can cause painting mobile parts of the mechanism.
  • The temperature at which the lubricant becomes liquid, should be more than 120 degrees.
  • Oil should not absorb moisture, must form a strong film that protects the parts from corrosion.
  • And also, most importantly, the oil should be such a viscosity that he has the opportunity to stay on mobile details.

The consistency or viscosity of the lubricant is divided according to NLGI (National Lubricating Grease Institute), while in certain cases it is necessary to use the oil of a certain density. The viscosity of the oil is selected depending on the speed of rotation of the gearbox, the higher it is, the more liquid should be oil. So, depending on the tool, viscosity is selected:

  • Drills, peorators, jigsaws, where the gearbox has a low rotation speed. Lubrication with the NLGI-2 index which is soft.
  • Light peorators and shock drills. Class NLGI-1, in consistency very soft.
  • Corner grinder, circular saws, motorcycles. Class nlgi-0, half-liquid in consistency.
  • Heavy peorators, junk hammers. Class nlgi-00, in consistency is liquid.

The main malfunctions of the gearbox and ways to eliminate them

With a gearbox of an electric or gasoline trimmer for grass, various breakdowns occur. The most frequent of them are presented in the table further. There you can also find the reasons for their occurrence and methods of elimination.

Reducer malfunction Possible causes of breakdown The method of elimination
The gear node is heavily warmed up the use of unsuitable (low.quality) lubrication or its absence you need to replace or add lubricants
The gears are new and did not get sick It should be worked for a short time for a time without strong loads with regular stops so that the mechanism manages to cool
shaking of the shaft during rotation, the appearance of backlash and knocking destruction or significant wear of any of the bearings replace the failed bearing with a new
The transmission mechanism flies from the rod of motorcycles or stagger Damage to its body It is necessary to replace the part
In some cases, with minor damage, a clamp made of metal, a place with a fault is carried out
not fixed on the pipe wear of the docking area you can make a winding from the insulating tape at the mounting site or change the bar
The output shaft with a knife does not rotate or stops in case of an increase in the load wear of the teeth on the gears or one of them It is required to replace the interacting pair of worn details

Bearings are destroyed due to the use of inappropriate lubrication or due to its absence. Their damage is also caused by severe operating conditions of motorcycles and the ingress of extraneous particles of the material (for example, broken metal teeth of mechanical transmissions) due to the fact that the integrity of the anthers is violated.

To remove the bearing, you need to disassemble the gearbox and use a special puller. If it is not, then you can try to do it with a hammer with a mentor. In this case, work should be carefully so as not to damage the seat. Using the pre.heating method to shoot the bearing is not recommended. This is due to the fact that the metal may lose the required operational characteristics.

Most gearboxes can easily be eliminated with your own hands. Replaced details are recommended to purchase “relatives” designed for the used motorcosa.

Removing and lubrication of the lower shaft of the lawn mower

To extract the shaft from the bottom of the bar, we initially remove the coil gearbox.

  • We unscrew the completely central fixing screw. On the back of the lower clamping screw, we turn the nut and unscrew the screw completely to disconnect the coil gearbox from the protective casing.
  • Weaken the upper clamping screw and remove the lower part of the bar from the coil gearbox body. We take out the lower shaft from the bar from the gearbox side.
  • Clean the shaft of pollution and grease it with a lubricant for a shred or lititol-24, not forgetting to clean and grease the coupling (sleeve) with slots in the gearbox.
  • We install the shaft in the bar, and the bar in the lower gearbox of the lawn mower and combine the hole on the bar with the hole for the central screw. We screw the central screw. Next, wrap the lower screw, clamp the lower part of the bar in the gearbox body with the upper and lower screws and tighten the nut on the back of the lower screw.
  • Add 20-30 ml of lubrication to the coil gearbox through a hole closed by a screw located in the photo on the right.

In the instructions for the operation of a trimmer for grass gasoline PRorab 8405m, 8406M, it is recommended to lubricate the gearbox with solidol or its analogues, in extreme cases pour liquid engine oil. Excess oil will flow out, since the gearbox does not have sealing oil seals.

In the guide of the user of a trimmer for grass gasoline PRORAB 8402R, 8403R, 8405R, 8406R it is written that the use of motor oil for two.stroke engines is allowed as a lubricant for the gearbox. There are no mention of solidol and his analogues.

In order not to bother, lubricate the lower gearbox with your lawn mower with the same grease as the shaft of the bar or fill the engine oil.

Sometimes with intensive mowing of grass, a trimmer for grass begins to gingern and make unpleasant sounds, which indicate the lack of reducer lubrication. This node is considered the most loaded, and therefore wears out faster. If it is not lubricated in a timely manner, then soon the drive can jam!

Why the chain is not lubricated

Oil does not enter the saw set as a result of violation of the chain lubrication system. Its reasons are as follows:

  • the presence of defects in the oil pump;
  • clogging of the filter, channels;
  • Sapuna defects;
  • rupture of an oil hose;
  • mismatchs of the oil opening on the saw case and tire;
  • The gear failure of the drive.

Dismantling and disassembling of parts will correct the identified defects and eliminate them with replacement with new.

The oil pump is responsible for increased or reduced oil supply and is located on the right side of the chainsaw. Due to its leakage or pollution, insufficient lubrication is possible. It is removed after the clutch is promoted.

The oil supply to the circuit is adjusted by setting up the oil pump.

Prevention of breakdowns

To avoid breakdowns and subsequent expensive repairs, it is recommended to comply with a number of simple rules for the operation of a trimmer for grass and servicing the gearbox.

  • Lubricate this garden tool immediately after purchasing. before starting operation. Usually or huter) applies only a small amount of lubricant, which is enough only for running.
  • At the end of the season or before a long.term storage of a trimmer for the grass, you should disassemble the gearbox, check the condition of the bearings and gears, grease the knot.
  • It is required to add grease after the tool works from twenty to forty hours. With intensive loads, this time is reduced to twenty hours.
  • Change grease to a new one is necessary when repairing a structure or before the start of the season.
  • Когда редуктор перегревается или издает сильный шум, нужно проверить наличие смазки. If it is present in sufficient quantities, it is recommended to replace it completely with another.

So, you can carry out repair and lubrication of the gearbox Motokosa yourself at home. The addition of lubricants will not be difficult, a detailed description of this process and recommendations for the choice of a suitable substance can be found in the instrument operation instructions or on the video, which many are presented on the Internet. Most of the breakdowns of gearboxes are typical for trimmers of different brands, it is quite easy to eliminate them if you know the correct procedure for actions. And in order to avoid their appearance, it is enough to observe simple operating rules and conduct timely maintenance of a trimmer gearbox for grass.

The main malfunctions of the gearbox for a trimmer for grass: how to eliminate a breakdown than to lubricate, video

To solve this problem, trimmers for grass are purchased. By the type of energy used for the drive, these devices are divided into gasoline and electric.

In order for a benzo or electric cost to serve as much as possible, it is necessary to take care of it. One of the necessary actions for such care is the maintenance of a trimmer gearbox for grass.

The main malfunctions of gasoline and electric trimmers

If you do not take into account damage associated with the bar and mowing head, the bush and electric trimmer for grass usually cause malfunctions in the engine.

Damage to gas trimmers

Typical breakdowns of a gasoline trimmer for grass, which are most often faced with the owners of this device:

  • Engine breakdown;
  • Problems with the carburetor;
  • Fuel supply problems;
  • Muffler malfunction;
  • Gear breakdown;
  • The starter is broken;
  • Air filter problems;
  • Cut the fan on the gas tank.

Defective electric trimmers for grass

Since the device of an electric mower is much easier than a trimmer for engine grass, there are little reasons for its failure.

Basically, a trimmer for grass ceases to work normally in the following cases:

  • Electric cable malfunction;
  • Faulty control button;
  • Winding of the burned engine stator;
  • Open contact on the engine.

Why does the gas trimmer not start

The reasons why the gas trimmer for the grass stopped starting can be different, so diagnosis of the device is required.

Fuel tank (fuel quality)

Always remember this before starting the device checking the presence and quality of fuel. In this case, do not be greedy and save money, as well as “be smart” regarding the amount of oil added. Everything should be done in accordance with the instructions attached to the device, because if the piston group fails, its replacement will cost about 70% of the total cost of the trimmer for the grass. Refill, hoping that you will use it completely during work. Gasoline left in the tank after a while loses its properties and can damage the engine. Therefore, do not prepare the mixture for further use and in large quantities. If the brush does not work, try to drain the “old” fuel from the tank and fill it with a freshly prepared mixture.

Candle and candle channel

So, you changed the fuel, but nothing has changed, and the trimmer for the grass still does not start. In this case, it is necessary to check the candles channel: whether it throws the combustible mixture. Often, users transfer the air damper to the “off” position when starting and when starting the engine do not install it in the “VCL” position, after which it hardens. Further, an attempt to restart the engine leads to the fact that gasoline flows a candle of ignition, and starting becomes impossible. To diagnose and eliminate the possible problem with this site, follow the following actions:

  • You need to unscrew the spark plug, wipe it well and dry. When installing the spark plug in the engine cylinder, it should be dry.
  • Drain the accumulated fuel from the combustion chamber. This is done through the hole from which you unscrewed the candle.
  • If there is a soot on the electrodes, it should be removed with a thin file or nail file.
  • Be sure to install the gap between its electrodes before replacing the part. The gap on the spark plug should be 1 mm. You can use a coin as an probe to check the gap.
  • Then collect the device, read the start instructions and try to start the engine again.

If the engine does not start, you need to check the spark. For this:

  • Unscrew the candle;
  • Put on it the lid of the high.voltage wire;
  • Touch the metal part to the cylinder body (you can insert a pipe key to provide contact), as shown in the figure below;
  • Pull the starter cord to make several engine speeds.

Usually, with each impact of the piston between the electrodes, the electrodes should slip a spark. If there is a spark, the reason why the engine does not start, you need to look in other parts of the device.

To better understand the process of checking the spark plugs, you can use this video where the test is shown by the example of the Soyuz gasoline baskets.

Masterforce 20 Volt Flexpower String Trimmer Line Replacement.

If there is no spark, then check the cable at the beginning, connecting the spark plug to the coil is probably the reason for this. You can call with the tester. In the case of a chain break, it is necessary to replace the high.voltage wire.

It can also lead to the disappearance of the sparking of the ignition coil (magnetopathic). The figure below shows what the coil (magnet) looks like from the gas trimmer for Patriot grass (Patriot).

Poor compression may also be the result of a free carburetor. Check if it’s free. If so, tighten the fasteners that holds it in place. Also, if the carburetor is free, you will notice that gasoline is dripping during operation.

Electric trimmer for grass vibrates

Many mowing users noticed that some time after the device began to work, it begins to vibrate very much. On some trimmers, mainly in more expensive models, an anti.vibration system was installed in the form of shock absorbers located between the engine and the bar. But in some cases, even this does not save from strong vibrations. The cause of strong vibration in the trimmer can be a small amount or complete absence of oil on a hard or flexible shaft located inside the rod of the device.

Replacing the hard lubrication of the shaft it looks like this:

  • Unscrew the gearbox located at the bottom of the bar;
  • Having removed the gearbox, you will see the end of the shaft, which needs to be pulled to remove the part;
  • After removing the shaft, it must be lubricated with a large amount of special oil “CV Joint-4” or usual. “Litol-24”;
  • Apply a small amount of oil to the shaft and grease it evenly along the entire length of the part, including the grooves at the ends of the rod (if they work together, the shaft will need to be replaced);
  • After lubrication, insert the shaft again into the stem and replace the gearbox.

Flexible lubrication of the shaft is as follows:

  • Unscrew and remove the mowing head;
  • Remove the stem from the engine by unscrewing a couple of bolts;
  • Pull out a flexible cable from the bar;
  • Lubricate the cable along its entire length.

This is done as follows: first you need to lubricate the end of the cable, and then insert it into the rod, then, moving inside the pipe, grease the part and evenly distribute it on the surface. Then insert a flexible motor into the motor and fix it.

Device, functions

The motorcosa gearbox transfers torque from the motor to the working (cutting) parts of the device.

This function is provided by the internal structure of the gearbox, which is a system of gears that lower or increase the speed of rotation of parts.

Gearboxes used for personal plots are:

  • wave;
  • cylindrical;
  • spiroid;
  • conical;
  • planetary;
  • worm;
  • combined.

This classification is based on the type of traction characteristic, namely the mechanical transmission of torque.

The gearboxes also differ in the form and dimensions of the landing hole: it can be square, round or starry. Of course, the most common gearboxes with a round landing place. At the location, the gearbox can be lower or upper.

For the normal operation of the mechanism, the lack of mechanical damage to the parts of the gearbox and maintaining a certain temperature regime is necessary. Any cracks, chips and overheating will lead to a malfunction and stopping of the lawn mower/trimmer for grass, which, in turn, will require the renovation of the gearbox. Regular lubrication of the mechanism can significantly reduce the risk of such problems and increase the life of a trimmer for grass.

The reducer lubrication algorithm

The gear mechanism of the gearbox, there is no need to disassemble the node. for this, a special hole is provided in the upper part of the case. In addition to the gear, it is necessary to carefully compose elements such as a bearing node. The wear of its compacted walls leads to the fact that the lubricant comes out of the seat and the vibration of the technique begins. This problem is relevant for Chinese trimmers. The decision would be to replace the “native” bearings with high.quality details. The flywheel is also subject to lubrication. during operation, the part is covered with fragments of grass, creating additional resistance during kosbe. Important! It is necessary to lubricate the dog’s reel dog, since when starting it touches the grooves on the flywheel. This leads to its wear, as well as to the appearance of mechanochemical corrosion due to the fact that the details are made of various materials (flywheel-aluminum, dog-steel).

Solid lubricant or oil are placed inside through a hole protected by a screw. At the same time, the following actions are performed:

grease, trimmer, grass, flexible
  • The gearbox body is carefully cleaned from contaminants, especially next to the plug to eliminate garbage entering the node;
  • A special device is supplied with a motorcycle, it is extracted by a cork;
  • From a tube or with a syringe, a lubricant is inserted into the hole, smoothly turning the cutting node so that the substance is evenly distributed along the gears of the gear;
  • Return to the same cork.

Advice! If there is a need to disassemble the gearbox, you should remove the old grease from the body, from the surface of the shaft and gears, and then apply a new. It is very convenient to lubricate the details with solids in disassembled.

The lubrication of the gearbox is required to be carried out annually, and with intensive operation, this procedure should be performed every 20 hours of operation of the tool. If signs of breakage appear, the lubrication site should be treated in the very near future.

Varieties of lubricants

To care for the units of the mechanism, lubricants of different consistency are used:

  • Semi.liquid. Such compositions contain a variety of additives and additives.
  • Plastic. Are the most universal option. Most often used for gear and screw gears.
  • Solid. Plate suspensions in its original state.

A special gear composition belongs to the semi.liquid system.

Popular is a grease for a trimmer for the grass “Stihl”. Thanks to the special composition and components, wear is significantly reduced and resistance to corrosion increases. The main properties of the lubrication of this brand are:

STIHL lubricant is suitable for black cutters and trimmers, as well as for all transmissions with a closed case.

Does the new or broken engine need to run?

For a long time in the world, discussions are underway about the a new or crossed engine. What do you think, is it necessary to run into modern cars? A few years ago, this question could obviously answer “yes”. But with the achievement of the latest technologies in the automotive industry, more and more people are inclined to the opinion that there is no need to run into the engine. Let’s find out if you really need to run a new motor?

First, to run the engine or not, each owner of the car decides for himself. For example, if someone took the car in leasing, then it is obviously he, most likely, will not take care of the engine. If the car is in our ownership, then we, as a rule, are careful about it. But is it necessary to run up modern cars?

Playing a new lawn mower.

Engineers and other experts claim that no. So, running is needed only for our psychological calm?

But why then, the BMW company, in its operating manual for new cars, directly recommends the first 1200 or 2000 km to limit the maximum engine speed (not more than 5500 rpm), and also not exceed the speed of 170 km/h?

That is, the BMW company officially admits that the engine is needed until a certain mileage appears on the car odometer.

BMW is not the only car manufacturer who still recommends the owners to observe the operating mode of cars. There are many more automobile brands, which also advise the user’s leadership to carry out the car of the power unit of the machine.

In this regard, we decided to figure out this issue, and to understand whether it is still needed or not. Firstly, let’s first find out what the engine is also and why, a few years ago, all the manufacturers of vehicles obliged the owners to spend its some time without exception.

The process of is the process of grinding of various components of the car to each other. For example, the piston rings of the engine and the walls of the cylinders, before reaching optimal levels of interaction and performance, should work together for some time, tortured, to each other. Until recently, no one questioned this fact. But today, many engineers and experts say that such a grind of engine components are no longer needed. In their opinion, modern technologies in auto industry allow us to achieve incredible accuracy of fitting components to each other today. The microscopic accuracy of the components of the engines allows you to refuse to

Read how to make a protective casing for a trimmer for grass

Experts believe that in the past drilling and other machines used in the production of engines were not so accurate as today. As a result of the clearances between the details, in the process of the first 3000-5000 kilometers, the parts of the engines, rubbing each other, formed metal shavings, polluting the engine oil.

Yes, today the tolerances between the details have become smaller, thanks to high.precision machines in the automotive industry. But, nevertheless, this does not directly say that the is not needed. After all, tolerances and errors are still. Nowadays, the sizes of details are also not perfect and will probably never be perfect in relation to each other.

In addition, the ideal interaction of engine parts is possible only after certain cycles of engine operation in a working (hot) state. That is, the metal components of the engine are necessary for a short time during which they will become optimal in relation to each other.

In general, as you can see, there is an opinion that is not needed, but there are many arguments in favor of the fact that is extremely necessary. And discussions in this area continues to this day.

So it is unambiguous to answer the question of whether the engine is needed, you will not be able to answer for sure. This requires expensive scientific research and long trials.

In general, modern engines, according to many engineers who work in automobile companies, need to run on an average of 1000 kilometers. In the past, it was necessary to drive much more than kilometers to run the engines before you could safely start using the power unit at full power.

But if you do not want to believe that modern cars are not needed in principle, and you want to be calm for the engine of the machine, then we offer you some tips that will save your mental STIHL after purchasing a new car or after the engine is redistributed.

Keep the average engine speed: depending on which engine in your machine (gasoline or diesel) you will have to limit the operation of the car at high speeds of the power unit after buying a new car or after buying out the motor. As a rule, diesel engines operate at lower speeds. Therefore, if you have a gasoline model, then the first 1000 kilometers do not exceed 3500 rpm. If you have a diesel car, then do not exceed 2500 rpm.

Be careful with the gas pedal: the first 1000 km be careful when working with the gas pedal. Try not to exceed the above engine speed. Especially careful when accelerating. Also consider your driving style first 1000 kilometers. You must remember that due to restriction of engine speed, you cannot fully use the power of the motor. Therefore, with maneuvers on the road, consider this so as not to create an emergency situation. For example, be careful when overtaking.

Try not to drive at minimum engine speeds. Your task is to go through the optimal within the first 1000 kilometers. Supporting the average engine speed, you accelerate the process of grinding piston rings and engine cylinders, and also accelerate their compaction process to each other. At minimum engine speeds, you will not succeed in only 1000 km, make the optimal running-in, since there will be no necessary high pressure, which is formed due to gases released during the combustion process of fuel.

TOP 5 errors when running around motorcycles. How to run a motorcycle? And the first launch)

Change the oil after 100 kilometers: if you have the opportunity, we recommend that you change oil in the engine after a run of 100-200 kilometers. As we said above, running-in is needed so that the details are injured to each other and the factory gaps are reduced between them, which are formed due to the errors of the equipment used in the manufacture of engines. As a result of the grinding, metal shavings are formed. These pieces of metal are present in the new engine after 100 kilometers. Changing the engine oil, you remove metal chips.



The choice of a benzocosille, or they are also called by the name of the cutting device. trimmers for grass, should be made from the volume of work, the more processed area, the more power is needed. For small plots, household are chosen, trimmers for middle.class grass are suitable for garden areas, for pumping a large area, especially if there are weeds or shrub thickets, a powerful professional tool is needed. park. Such a technique has an engine power of more than 2.5 liters.With. And it can work 3-4 hours a day.

The trimmer gearbox for grass includes 2 shafts. the first has a drive from the engine, and the other is used to rotate the cutting blade Motokos or Electimimer fishing line. Conical gears are made as a whole with a shaft, but there are versions with the installation of a separate part on the slotted connection. Models with different angles of the location of the teeth are available, which depends on the layout of the tool. There are modifications of gearboxes with worm, planetary or mixed (multi.stage) gears.

Shafts are installed on rolling bearings, which are closed with protective washers. Details ensure the preservation of lubricant and prevent dirt from getting on the workplace. The bearings are installed in the gearbox body made of aluminum alloy. The unit unit, consists of 2 symmetrical halves, which are interconnected by screws. To ensure the tightness of the joint, a separate gasket or sealant is used.

The lower gearbox for a trimmer for grass is installed on the tool through the planting nest. There are several varieties of the joint that differ in shape.

The most widespread are round seats with a diameter of 24 or 26 mm.

There are modifications of the tool with a square or multifaceted joint of elements. The transmission of torque is carried out through the slotting connection.

User reviews about lubricants

Experts advise using only original materials, the characteristics of which meet the requirements of the manufacturer. If there are no one, you should clarify how to lubricate the gearbox of the trimmer for the grass. Experienced users do not advise using solidol, because this material is not suitable for the temperature and speed characteristics of the node, as well as in consistency. Also, the above material does not have anti.intelligence properties.

The range of operating temperatures of the solidol is from minus 40 to 65 degrees, but even with such parameters in the process of heating, the density of the material increases, and the lubricant itself becomes rough. With emergency need to process the tool, you can use Litol-24.
