Husqvarna Trimmer Gear Grease

Lubricant for trimmer gear. How and how to lubricate?

Husqvarna Trimmer Gear Grease

Sometimes, in the midst of an intense mowing operation, your trimmer will start making an unpleasant grinding noise. This complains about the lack of lubrication of the gearbox. The most heavily loaded unit of the device. And soon on These “Warning” may follow and jamming of the drive.

What kind of lubricant should be used for the trimmer gear?

During operation, the mechanical part of the trimmer is loaded by contact forces on the teeth, resistance reactions from adhered grass (sometimes with dirt), dynamic, shock loads due to constantly changing torque. Lubricant for the trimmer gear must fully take into account these features, so the selection of the brand must be strictly individual.

The following factors are taken into account:

  • Manufacturer’s brand. Each brand reasonably focuses on self-made lubricants (you can talk about cheap Chinese products later). This applies to manufacturers such as Husqvarna, Stihl, Huter, Makita, etc. The only exceptions are domestic trimmers: for example, the Caliber in the user manual does NOT indicate the brand of lubricant at all.
  • The viscosity of the lubricant. As you know, all lubricating compositions are divided into three groups. high-viscosity (colloidal systems containing various additives), plastic compounds for universal use and solid lubricants that soften during operation.
  • Good adhesion to the surface of gearbox parts, as a result of which the grease is NOT squeezed out into the gaps or out of the unit.
  • The rate of grease consumption by the gearbox. Here you have to rely on your own experience and the recommendations of specialists, since some trimmer manufacturers, relying on their own service centers, do not give clear recommendations at all for the period of the gearbox operation between two lubrications.

Lubricant consumption also depends on the temperature at which it retains its lubricity. When the gearbox is heated to 40 ° C, it is considered that its operating conditions are satisfactory, and there is sufficient lubrication.

It is believed that there is no universal grease for the trimmer gearbox, but this is not entirely true. In fact, a suitable lubricant will be one in which the following components are present:

  • Lead-free antiwear additives;
  • Solid lubricants with the presence of graphite or molybdenum disulphide (the latter is preferable, since the lubricity is fully retained for a wide range of shaft speeds)
  • Only mineral (inorganic!) Oils, highly refined.

These requirements are fully met by Gear Grease OREGON or Champion EP-0 lithium greases, domestic compositions Oleo-Mas, Litol.24, or Azmol 158, as well as what is recommended by the manufacturer of a particular trimmer model.

How to Lubricate the Trimmer Gearbox?

In the upper part of the body, where the gear block is installed, there is a technological hole, which is plugged with a screw during trimmer operation. This screw is unscrewed, and 1.5. 2 ml of lubricant is injected into the hole using the spout on the tube. If the lubricant was purchased in a different package, then an ordinary disposable medical syringe is also suitable for this operation.

After that, the screw is reinstalled. This procedure, regardless of the user’s recommendations, should be performed every 10. 15 hours of operation of the trimmer in working mode. Other reasons for updating or replacing the gearbox lubricant are the independent performance of minor routine maintenance (for example, cleaning and flushing the gears of the gearbox before the start of the summer season), repairing the unit, preserving the trimmer for the winter, etc.

If the gear unit is disassembled, it is recommended to completely remove the remnants of the old grease from the surface of the parts, even if it does not have any traces of oxidation and contamination. And only then applies new lubricant. After applying the lubricant, it is recommended to turn the shaft several times by hand, and make sure that the lubricant is evenly distributed over all parts of the gearbox.

When lubricating, pay particular attention to the following elements:

  • Flywheel: grass residues tend to stick to its surface intensively, and thickening herbal juice creates additional resistance.
  • Pawl of the starter coil, which, in the process of turning on the drive, constantly contacts the grooves on the flywheel. In this case, not only mechanical wear occurs, but also mechanochemical corrosion of the “flywheel-dog” connection, since the materials in 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 grease is squeezed out. In this case, the unit begins to vibrate intensively when loaded. This happens with Chinese-made trimmers, so it is worth thinking in the future about replacing the bearings of the assembly with a better one, for example, from the Swedish company SKF.

Care and maintenance of lawn mowers

Maintenance of lawn mowers, both with gasoline and electric motors. Although it has its own differences, it is quite possible on its own. Watch the sharpness of the blades, sharpen them correctly if they are dull. this is not a particularly difficult task. If you have equipment for sharpening at home, you can sharpen them in workshops. To ensure that they wear out equally on both sides, periodically turning them over to the other side.

The air filter, which is installed on a gasoline scythe, should be checked at intervals of one week, and not less often. Moisten with oil, if necessary, change if dirty. Checking the candles and muffler for soot contamination.

If the engine is with electric power supply, it is necessary to alternate the operating time specified in the passport with the engine cooling time. If the equipment has a cutting element of the line, it also needs to be monitored, the spool on which it is wound is also periodically cleaned.

Untimely cleaning in the electric motor leads to the accumulation of moisture in it, the gasoline engine to a loss of its power.

It is especially important to pay attention to the maintenance of the gearbox. This detail is very important in the mower operation, unless the engine is directly connected to the cutting unit.

The first one is Watch out for dirt that accumulates there.

Second, DO NOT forget to apply the grease in time, which is intended for the trimmer gear. You can ask an equipment dealer what lubricant is needed for the trimmer gearbox, which you are going to buy. They will answer this question as correctly as possible, since the service life of the trimmer depends on this, and this is already a warranty. Some trimmer manufacturers recommend using their proprietary trimmer gear lubricant, such as Husqvarna, Huter, Makita.

Husqvarna trimmer gear grease

The fact is that during operation, the load on the gear train increases, since the rotation speed is constantly changing. At the same time, adhering grass, especially in wet weather or dew, creates its own additional load. When deciding which lubricant is best to use for your trimmer gearbox, you need to decide separately for each model.

If these are Russian or Russian-Chinese manufacturers, the specific brand of grease is not specified here.

Trimmer device and main differences in models

If you disassemble any gasoline mower, you can make sure that it is made in almost the same way, with the exception of additional options and design.

The structure of the gasoline trimmer

If it is an electric tool, it has a slight difference:

Electric trimmer, configuration example. 1. engine running on gasoline; 2. fuel tank; 3. starter handle; 4. rod, can be disassembled, telescopic, one-piece; 5. the handle, which is controlled during operation, can have a different shape; 6. buttons for trimmer control; 7. the connection of the buttons with the engine occurs via a small cable; 8. gearbox, which needs constant maintenance and the addition of special oil. It transmits rotation from the motor to the shaft on which the spindle is mounted; 9. a cutting tool, which is attached to a spindle, which, in turn, consists of a spool of fishing line, which is used to cut grass, or a special knife; 10. casing to protect the worker from flying pieces of stems.

As you can see from the photo, its difference is that there are not so many control buttons, there is one. either turn it on or off, the engine can be located either below, near the cutting tool. In this case, it is easier to work with such a tool, but it is not recommended to mow wet grass. But in this case, the gearbox, as a part, is absent, since the rotation is transmitted by the FRA from the engine directly to the spindle shaft and the cutting unit. Naturally, like all other equipment in which there is no gearbox by design, it has a small power.

If the engine is on top, it is more practical and the engine is more durable.

Trimmer with motor in the upper part as a complete set

In addition, such a mower has much more power.

If we consider the battery version, it has a motor and battery at the top of the boom.

Types of trimmers

For a long time, they have not used such a lawn mowing tool as an ordinary scythe to trim the lawn. Of course, in the villages this tool remained, but in a country house or in the country, in order to mow a lawn or a lawn overgrown with grass, overgrown with grass roadsides, they use a trimmer. This is a type of garden tool that combines a scythe and a lawn mower.

Trimmers are different, but basically they can be used in three types. These are petrol, electric and battery powered.

The most powerful are gasoline-powered lawn mowers. They are considered a professional tool, they are used not only for lawns near the house, but also by employees of housing offices and road administrations to bring lawn areas in order. The engine of this tool is of great power, usually air-cooled. Having a container with gasoline and oil for the engine behind his back in a backpack, the worker is NOT tied to a place and can process large areas at a considerable distance, and with a sufficiently high speed of work.

Petrol trimmer in operation

Of course, such a tool also has its drawbacks, for example, a large amount of exhaust gases, a lot of noise, which can be heard even with closed windows, when they mow the grass with it on the street. If, for example, something of the trimmer parts fails, it will be difficult to make repairs yourself without work experience. In addition, it has a large, comparatively, weight, it will be difficult for a woman to work with it, and the price is much higher than other types.

Electric powered tool, powered by electric cable, less powerful tool. It has an upper engine layout and a lower engine layout. Both models have their pros and cons. Due to being tied to a power source, it is used in private households, although you have to equip the device with an extension cord.

Power cord trimmer

But they are more convenient to work with and are lightweight. In addition, the noise and vibration levels are small, although they will NOT be able to mow thick plant stems with it. Easy to repair and maintain. Affordable prices.

The third type of trimmer is rechargeable. They do an excellent job where it would be impossible to approach mowers with a cable, they are comfortable to work, they can be easily carried from place to place, they will NOT get tangled in the wire and will NOT cut it. Quiet, inexpensive.

There are difficulties in their work, this is a battery that constantly needs to be recharged, the smallest power in comparison with other types. Therefore, they are bought as an addition to the other two instruments, and the choice of models is not so large.

What is the best lubricant to lubricate the trimmer gear

Many people use Litol for this purpose, its only advantage is its low price and many people change the lubricant in the trimmer gearbox to Litol. At the same time, this grease is thicker and more viscous than in specialized greases; it does not have special additives in its composition. Therefore, you need to constantly monitor the level of lubricant in the gearbox, add it every 20 hours. In addition, Litol cannot be used on aluminum parts. Therefore, both its performance and its service life will depend on what kind of lubricant will be in the trimmer gearbox.

As already mentioned, it is very good if, when buying a mower, you immediately purchase lubricant from the same company as the mower.

In addition to the fact that special lubricants have a density and viscosity required for such parts, it must be remembered that children can play on the lawn, adults can relax and that grease waste, unsuitable for this purpose, is unnecessary.

How to lubricate and add lubricant to the electric trimmer gearbox

In order to lubricate the gearbox, there are technological holes in it. To do this, unscrew the cap of the lubricant tube and squeeze the lubricant into the hole.

We unscrew the screw and inject grease into the technological hole

If the grease is in another container, fill in a syringe with a capacity of 5 cubes and inject the grease through the syringe.

Can also be injected through a tube

If this is a gearbox from a gasoline engine, we find the plug, it is usually indicated on the diagram. And a little more than the gearbox of an electric mower. We clean it and the place around it, so that the dirt would miss inside when opening. Then, put the trimmer on the surface (it must be turned off) sideways and with one hand squeeze out the grease slowly in the above way, and with the other we rotate the knife so that the grease is evenly distributed inside. Then close tightly the stopper on the reducer and the tube or syringe. You need to lubricate at least after 25 hours of operation, and you yourself choose which lubricant to lubricate the trimmer gear. The principle of operation of the gearbox and gasoline and electric is the same.
