Lubrication of a trimmer for grass for grass gasoline STIHL. Rod and the drive of the working body

Lubricant for a trimmer gearbox for STIHL Evdiral grass.Ru

Reducer Motokosa Purchase of any equipment in its kind a lottery, but much also depends on the gardener. In caring hands and Chinese samples serve for a long time and do not let their owners at the wrong time. And if you forget to lubricate the motorcosa gearbox in time, do not clean filters, use cheap low.quality gasoline, then garden equipment from the most eminent brands will be a headache.

Lubrication of the gearbox Motokos is one of the most important elements of maintenance of a gasoline trimmer for grass, which the user should be carried out directly.

Time and procedure for the prevention of the gearbox

I recommend that the prevention of a new gasoline trimmer for grass immediately after purchase, with the addition of lubrication in the gearbox. For all the high cost of garden technology, some manufacturers save and lay lubrication only at a minimum, for the duration of the

How often to lubricate the gearbox motokos

Often, a preventive inspection of the transmission with the addition of liquid consistent lubrication is carried out once a year at the beginning or end of the season. If the gasoline trimmer for grass is used not in professional volumes, this is enough.

With large volumes of the mowing, lubricate the motorcosa gearbox every 20-50 hours of work. If the conditions of the operating mode of garden equipment are difficult, for example, a large field is pumped out at a time, and at the same time the lawn mower does not have time to cool down, or cheap lubricants are used, then the lubricant must be checked and added every 20 hours of work.

Indirect evidence that it is necessary to lubricate the gearbox to overheating or increased noise of the node.

I also recommend a complete replacement of lubrication, with disassembly and flushing of the node, when buying a used gasoline trimmer for grass.

Assortment of lubricants for garden technology

According to the instructions for lubricating the conical gearbox, a special transmission liquid consistent grease should be used. As a rule, manufacturers of garden equipment produce and recommend the chemistry of their brand as the most adapted to their devices.

Stihl chainsaws and trimmers

At the same time, to reduce the cost of the operation of garden equipment and increase the attractiveness of a brand of auto chemistry, grease for garden equipment usually produces multifunctional. It is intended not only for lubricating gearboxes of gasoline trimmers, but also for processing hoses, transmissions and gearboxes of any garden equipment and mechanical devices operating under high loads.

Such lubricant for the gearbox is sold in the tubes convenient for use and subsequent storage.

Even if a specialized lubricant for the gearbox was almost completely developed during operation, the additives still create an effective lubricating protective film on the surface of the gears.

It should be noted that many owners of the motorcycle in the vast CIS for lubrication of the gearbox use ordinary litol-24 or lubricant for Circus on a lithium basis. It is convenient to refuel the gearbox using a 5-cc medical syringe.

A undoubted plus of the use of lithola and lithium.based lubricant for refueling the transmission of motorcycles is a reduction in operation. But there are nuances because of which spears are breaking on the forums of the Internet gardeners. My thoughts on the topic, what can be lubricated with lubric.based lubricants, and what is not read in the article “Litol as lubrication of the motorcosa gearbox”.

How to lubricate the motorcosa gearbox, gasoline trimmer for grass

Side Bolt on 17 on the gearbox of a gasoline trimmer for grass

In order to avoid random launch, all preventive work on a motorcycle is necessarily carried out with a removed electric cap / plug from a candle. Do not turn the trimmer for the grass to avoid gas leakage.

We unscrew the side screw on the motorcosa gearbox. Depending on the company.manufacturer of a garden tool, instead of a screw for a hexagon, there may be a turnkey bolt, more often at 17. The thread is ordinary, unscrew counterclockwise. Do not lose the sealing puck.

If the lubricant is not visible on the internal end part of the screw, then it is necessary to add 3. 4 grams. Scroll through the gear with your hand, changing the direction of rotation so that the lubricant is distributed through the gears.

Then set the screw in place, tightly tightening it.

Why choose a FS 55 lawn mower

If you still do not know which model of the described equipment to choose, then you should read reviews about the gas tanks “Stihl FS 55”. Having familiarized themselves with them, you can understand that consumers identify many reasons that made them bow towards the described model. So, for example, instead of a strap, the manufacturer supplied the device with a belt. This allows you to distribute the load from the device throughout the back. Otherwise, the weight would be focused on only one shoulder. With this option, even after a very long operation, there is no back pain.


Buyers like a bicycle handle that increases the convenience of management. When working, the hands will be widely placed, so it is easier to control the aggregate. He is very maneuverable. Buyers like that the handle and belt can be adjusted for the needs of the operator.

The tool can be easily configured for comfortable use. Control elements are on one handle. You need to stretch anywhere, everything is located under the palm. The Stihl FS 55 lawn mower, according to consumers, is also convenient for the fact that it has a couple of protective covers, one of which is installed for a knife, while the other is for fishing line. The casing for the latter has a narrowing of the bar.

A trimmer for grass has a head that is clearly visible and allows you to process narrow places. The departure of stones from under the knife will be excluded thanks to a special casing. This allows you to protect the operator. With the help of an existing primer, you can pump up fuel into a carburetor. Even after a long downtime, as consumer reviews testify, the lawn mower is quite simple. The start of the engine is light due to a special light starting system. As the home craftsmen emphasize for a long stretch of the cord, now you will not have to spend strength, because for this it will be necessary to make 2 jerks.

Lightened lawn mower “StiHL” will be the perfect option for effective and quickly ennoble the site. A steep unit can operate for an hour without pauses due to the fuel tank captive for such a compact device (600 ml). The gasoline engine fully complies with the standards of environmental nature in terms of emissions and economically consumes fuel even during intensive work.

A trimmer for grass is best adapted for processing small areas up to 20 acres. it carefully trims flower beds, lawns, beds, while easily avoided any barriers on a personal plot. The operator practically does not get tired during work (the reviews of women who worked with this tool are best said about this), since FS 38 weighs only 6 kg and, in general, is very compact. Another undoubted advantage is an ergonomic handle, which reduces the tension in the hands during the mowing of hard vegetation.

There are no complex areas for such a Range motorcycle manufacturer “STIHL”. It can be used on the slopes, between the trees, along the beds, removing almost any kind of vegetation. Ergostart starting device provides a fast start of a trimmer for grass. The ergonomic handle is equipped with a special system that absorbs vibrations from rotation of the engine and cutting tools. All the necessary management levers are directly on it. it is much simpler and safer, since the operator does not have to let out the handle out of hand during work.

According to reviews, FR 410 C-E gives not only comfort in work, but also one of the most economical gasoline models. The branded compensator in the carburetor provides not only the constant power of the motor, but also reduces fuel consumption. by almost 20 %! At the same time, the unique 2-Mix technology in a two-stroke engine reduces the volume of exhaust gas emissions by 70 %.

STIHL for a two.stroke HP engine, 1 liter

The most popular brand. Choice of the buyer Country: Germany Medium rating (2022): 4.eight

Mineral motor oil, designed for the requirements of gasoline instruments of domestic and imported production, is characterized by good lubricating properties and the optimal ratio of additives. Consumers praised the wide possibilities of this lubricant. It can be poured into trimmers for grass, lawn mowers, chainsaws with two.stroke engines. At the same time, there is a good surface tension of the oil film, the rapid launch of the motor, a decrease in vibration and noise during operation.

STIHL HP oil is also released with sufficient viscosity-it reliably covers all the elements of the 2-stroke engine and does not flow into the pallet if the temperatures are approaching extremely high, but does not freeze if they are lowered below zero. Lubrication effectively neutralizes the negative impact of low.quality fuel, extends the replacement period, which makes the use of garden technology as a whole more economical and reliable.

Daewoo Power Products 2 Stroke Engine Oil Tb 0.6 l

All kinds of garden equipment (chainsaws, gasoline trimmers for grass, lawn mowers, motoblocks) need the mandatory protection of the engine, which in these units, as a rule, is a two.stroke. The oil of this brand extends the motor service resource, lubricating each element and preventing its wear and damage. Suitable for summer use. you can pour only at an air temperature not lower than 0 degrees.

Since devices with a 2-stroke engine can operate on maximum loads, the use of Daewoo Power Products 2 Stroke Engine Oil Tb oil helps prevent the formation of soil in the exhaust system, shifting rings and increasing the energy of friction energy. This product is also distinguished by good thermo.acidic stability, contains a package of additives that improve its characteristics and give the ability to maintain lubrication properties at extreme loads and high temperatures.

Cooking the fuel-oil mixture correctly

Gasoline trimmers for grass with a two.stroke power unit receive the necessary lubricant along with fuel. The quality of the preparation of the mixture largely determines the long.standing operation of the tool. In some models, the kit includes a special cooking container with the marking applied, but if it is absent, there is nothing to worry about. You will need an empty container (an ordinary glass jar or a bottle is best suited, but the food PET-car is dangerous in that it is easily electrified and can cause a fire) and a medical syringe at least 20 cubes. Now follow the following actions:

Flush. The syringe oil is squeezed out with good pressure, and the subsequent filling into the fuel tank additionally mix the mixture. The main thing is to perform the procedure away from open sources of fire and as neatly as possible.

How to lubricate the gearbox of a trimmer for grass?

In the upper part of the case, where the gear unit is installed, there is a technological hole that, when operating the trimmer for the grass, is drowned out with a screw. This screw is twisted, and 1.5 2 ml of grease is introduced into the hole using a nose available on a tube. If the lubricant was purchased in another packaging, then a regular disposable medical syringe is suitable for this operation.

After that, the screw is installed in its former place. This procedure, regardless of the user’s recommendations, should be performed every 10 15 hours of operation of a trimmer for grass in working mode. Other reasons for updating or replacing the reducer lubrication are the independent performing of small regulatory work (for example, cleaning and washing the gear of the gearbox before the start of the summer season), repair of the node, preserving the trimmer for grass for the winter period, etc. D.

lubrication, trimmer, grass, gasoline, stihl, drive

If the reducer node is disassembled, it is recommended to completely remove the remaining lubricants from the surface of the parts, even if it does not have traces of oxidation and pollution. And only then apply a new grease. After applying the lubricant, it is recommended to handle the shaft several times manually, and make sure that the grease is evenly distributed over all the details of the gearbox.

When lubricating, special attention is paid to the following elements:

  • Flywheel: on its surface, as a rule, intensively sticks the remnants of grass, and thickening herbal juice creates additional resistance.
  • Dog of a starter coil, which in the process of turning on the drive is constantly in contact with the grooves on the flywheel. At the same time, not only mechanical wear occurs, but also the mechanochemical corrosion of the Makhovik-Sobachka compound, since the materials of this pair are different (the flywheel is aluminum, and the dog is steel).
  • Bearings, if their seals are worn out, and through them the remaining lubricants are squeezed out. In this case, the unit begins to vibrate intensively when loading. This happens with trimmers of Chinese.made, so it is worthwhile to think about replacing a bearing unit with a better, for example, from the Swedish company SKF.

About the manufacturer Stihl

The history of this German brand begins in 1926. At the initial stages of its development, the company was engaged in the production and implementation of various components for washing and steam machines. It all began, like many companies, with a small production and narrow orientation, which made it possible to focus on the quality of the manufactured products.

In the early 30s, the first Stihl chainsaw was released, which is characterized by convenience and functionality in those days. The company is developing at a long time, constantly introducing new tools, which gives it the opportunity to enter the international market. And already in 1931, the first regular supplies of products were organized at the moment, the company has launched its activities in more than 160 countries of the world, opening new centers and production departments in Switzerland, China and many other states. This is understandable, because the assortment of the company is impressive: motoburs, gasoline sprayers, mowers, gasoline trimmers for grass, chainsaws and much more. I would like to note that Shtil chainsaws are very popular due to their functionality and acceptable price.

Fuel mixture requirements for a two.stroke engine

The difference between a two.stroke engine in increased power compared to a four.stroke engine. it is prepared in a certain ratio of gasoline and special oil. What is the relationship of oil and gasoline for gasoline pumps is optimal, indicated in the instructions. Recommended proportions must be observed accurately. When adding additives, the manufacturer took into account the type of engine. Therefore, mixing of various oils is prohibited.

Using mineral oils, mixing occurs in a proportion of 1:25, 1:30, 1:35. For synthetic oils, use a ratio of 1:50 or 1:80. This means that in each of the proposed mixtures the required amount of oil dissolves in the volume of gasoline. Mixing gasoline with oil for gasoline can be like water with syrup. It is necessary to fill in gasoline, add the exact amount of oil and shake the mixture. It is advisable to use a new solution to work. When stored for more than 2 weeks, the composition changes, and the oil film causes a violation of the carburetor operation.

To dilute and store the combustible mixture, you cannot use PET but. Gasoline destroys plastic, polymer dissolves in the fuel mixture and further worsens the quality of the fuel, creating the danger of the appearance of stray currents.

The choice of proper gasoline

Two.stroke engines are loaded with a mixture of unhealthy gasoline and oil labeling 2t. In this case, you must use the recommended gasoline AI-92. If you use a brand with a higher octane number, the flash temperature and combustion will be higher, the valves will be premature. The same goes for oil. The recommended composition is not the most expensive. But the use of another brand is unacceptable. The viscosity will change, this will lead to insufficient lubrication of ordinary products made without grinding with high accuracy.

If the oil is added excessive, incomplete combustion will lead to the formation of carbon and excessive exhaust into the atmosphere. A rich mixture is harmful to the engine. For a four.stroke engine, the oil spills separately from gasoline. It cleanses the nodes, cools, reduces friction. During operation, the oil becomes dirty, and after 50 working hours it must be replaced. What oil is spilled into a gasoline pump specified in the passport. The composition should be labeled 4t with a viscosity of 10 W40.

Reducer of the lawn mower.How to lubricate and how easy to determine that it needs to be lubricated.

What to do with the gearbox of the lawn mower, so that it has served for many years.

Check. Is there a lubricant on your shafts gas. Most likely there is dry!

However, gasoline models of trimmers, it happens, fail. This can happen for various reasons, quite often due to improper maintenance of the device.

Remember that gasoline trimmers for grass need periodic cleaning of the fuel tank and oil replacement.

Trimmer lubrication and its use

In order for the gasoline or electric trimmer for the grass to serve for a long time, and its work was as reliable as possible, it is necessary to perform periodic maintenance of individual elements. The care process does not take much time, includes lubricating the rubbing parts and cleaning the filter.

The gearbox and shaft are most susceptible to wear, for which a special lubricant is intended. It is on sale in most stores of garden equipment and tools.

The gearbox includes a crankcase with many gears that intensively interact with each other, transmitting the torque.

Lubricants reduce friction, so the wear of the parts is significantly reduced. To add the composition to the gearbox, you need to unscrew a special bolt on the housing, and then squeeze the contents of the tube inward until the entire space is filled completely.

For the production of trimmer lubrication, special ingredients are used, which meet the most stringent environmental standards and decompose in the environment after use, without damaging it.

The consistency of increased viscosity during heating decreases in density, so reliably protects the clutches at maximum temperatures.

The frequency of a change in the substance on average is about 50 hours of the general work of the apparatus, more accurate data of a particular model are indicated in its technical passport.

In addition to the gearbox, a trimmer shaft for grass needs care. It should be abundantly lubricated immediately after the purchase (if the manufacturer has not provided for this), and before that it is well cleaned.

In addition, all the joints of the rubbing parts are recommended for lubrication. The transition from the motor to the flexible shaft and the junction of the shaft with the rotating head. This significantly increases the reliability of work and the life of motorcycles.

So that the owner of a trimmer for grass can save on the purchase of individual lubricants for the shaft and gearbox, manufacturers develop universal products that are suitable for all parts immediately.

It is worth noting that not only powerful gasoline trimmers for the grass need mandatory maintenance. Electric models also significantly extend their service, if they are lubricated before seasonal use and after its end.

Technical characteristics of a trimmer for grass

In addition to the good quality of the assembly, the Stihl FS 38 lawn mower is highlighted by worthy factory parameters.

The list of the most important characteristics of the garden tool includes:

  • Power of the factory ICE. 0.9 liters. With. at 9500 rpm;
  • tank for refueling the fuel mixture. 330 ml;
  • maximum fuel consumption. 320 ml/h;
  • Coverage when mowing with a fishing line/knife. 38/25.5 cm;
  • sound effect on the operator. 97 dB;
  • Weight. 4.2 kg.

STIHL trimmer differs from analogues with modest dimensions. The length of the motorcycles is 147 cm with dismantled cutting equipment.

What lubricant should be used for a trimmer gearbox for grass?

In the process of work, the mechanical part of the trimmer for grass is loaded with contact efforts on the teeth, resistance reactions from adhering grass (sometimes with dirt), dynamic, shock loads due to a constantly changing torque. The lubricant for the gearbox of the trimmer for the grass should fully consider these features, so the selection of the brand should be strictly individual.

The following factors are taken into account:

  • Manufacturer’s brand. Each trademark is not unreasonably focused on lubricants of its own manufacture (you can talk about cheap Chinese products later). This applies to manufacturers such as Husqvarna, Stihl, Huter, Makita, etc. The exception is trimmers for domestic grass: for example, the caliber in the user’s instructions does not indicate a lubrication brand at all.
  • Break of lubrication. As you know, all lubricants are divided into three groups. high.speed (colloidal systems containing various additives), plastic compounds of universal use and hard lubricants softening during operation.
  • Good adhesion to the surface of the parts of the gearbox, as a result of which the lubricant is not squeezed into the gaps or outside the node.
  • The intensity of lubrication consumption by the gearbox. Here you have to focus on their own experience and recommendations of specialists, since some manufacturers of trimmers, hoping for their own service centers, do not give clear recommendations at all regarding the period of the reducer between two lubricants.

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.

Lower reducer of trimmer for grass Prorab-8406

  • 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!


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.
