Proper maintenance is the key to long and reliable operation of the tool. Primitive maintenance operations include timely lubrication of the gearbox and cleaning the trimmer filter. And every user should know how to lubricate the trimmer gearbox. Cleaning is carried out in several stages:
- After removing the casing, the element is removed.
- Next, it is washed with gasoline and dried (naturally).
- The area under the filter is cleaned of residual oil and dust.
- Check the rod for rotation during operation.
Is it possible to lubricate the trimmer gearbox with grease if there are no other means? No, for long service life, equipment manufacturers recommend using specialized lubricants. Some manufacturers develop care products that are adapted directly to the branded tool. To lubricate the working pairs, you just need to unscrew the plug and pour liquid into the container.
Gearbox prevention: frequency and order
First of all, prevention is carried out immediately after purchase. This is due to the fact that many manufacturers provide a minimum amount of lubricant, which will only be enough for the break-in period.
If the trimmer is used at home (the amount of work is small), it will be enough to add lubricant at the beginning and end of the season.
In severe operating conditions, the gearbox of a gasoline trimmer must be lubricated every 20-50 hours of operation. Indicators for urgent preventive maintenance are increased noise of the unit and overheating. If a lack of lubricant is detected, it should be completely replaced.
Manufacturers often produce multifunctional auto chemicals. This means that the lubricant for gasoline gearboxes is also suitable for treating hoses and transmissions of any garden equipment and components that operate under high loads.
Performance
The choice of petrol mowers, or they are also called by the name of the cutting device - trimmers, should be made based on the volume of work; the larger the area being processed, the more power is needed. For small areas, household trimmers are chosen; for garden plots, middle-class trimmers are suitable - farm trimmers; for mowing a large area, especially if there are thickets of weeds or bushes, you need a powerful professional tool - a park one. This technique has an engine power of more than 2.5 hp. and can work 3-4 hours a day.
Gearbox lubrication process
A gearbox is a mechanical device that is designed to transmit torque from the engine to the cutting equipment. Located at the bottom of the trimmer.
Immediately before maintenance work, remove the electrical cap (or plug from the spark plug). Do not turn the trimmer over to avoid fuel leakage. To change the lubricant, the device must be disassembled.
The disassembly process consists of the following steps:
- The side screw is unscrewed.
- If there are no traces of lubricant, then it should be added (3-4 grams).
- The transmission is then scrolled manually. This is done to ensure uniform distribution of material across the gears.
The operation is performed several times. The assembly should be tightly filled with lubricant. At the end of the operation, the screw is replaced and tightened tightly.
To lubricate the trimmer gearbox, you need to clean the plug and the area around it from dirt, and then unscrew it. The petrol mower is laid on its left side. By rotating the gear, lubricant is simultaneously added to the gear housing until it is filled.

those. Are the proportions indicated on the canister for break-in and after?
any for 2-stroke engines or one for which you don’t mind the money
z.y. I don’t like these 2-stroke bikes: if you overfill oil, it smokes, if you don’t top it up, you can ruin the engine

How to choose the right lubricant
During operation, the mechanism components are loaded by contact forces on the teeth, resistance reactions when debris enters, as well as dynamic and shock loads. Depending on the characteristics of the load, you should choose what to lubricate the trimmer gearbox with.
When selecting, the following factors should be taken into account:
- manufacturer's brand;
- lubricant viscosity (the selection of this parameter depends on the shaft torque);
- adhesion to the surface of assembly parts;
- intensity of lubricant consumption (ambient temperature, type and volume of work should be taken into account).
If you do not have the necessary lubricant, you can use a universal one. The latter must contain some components:
- anti-wear additives (without toxic lead);
- highly refined mineral oils (inorganic);
- solid lubricants with graphite or molybdenum disulfide.
Device
The trimmer gearbox includes 2 shafts - the first is driven by the engine, and the other is used to rotate the cutting blade of the brush cutter or electric trimmer line. Bevel gears are made as a single unit with the shaft, but there are versions with the installation of a separate part on a spline connection. Models are available with different tooth angles, which depend on the layout of the tool. There are modifications of gearboxes with worm, planetary or mixed (multi-stage) gears.
The shafts are mounted on rolling bearings, which are covered with protective washers. The parts ensure the preservation of lubricant and prevent dirt from entering the work paths. The bearings are installed in a gear housing made of aluminum alloy. The unit is detachable and consists of 2 symmetrical halves, which are connected to each other with screws. To ensure the tightness of the joint, a separate gasket or sealant is used.
The lower gearbox for the trimmer is installed on the tool through a mounting socket. There are several types of joints, differing in shape.
The most common are round seats with a diameter of 24 or 26 mm.
There are modifications of the tool with square or polyhedral joints of elements. Torque transmission is carried out through a splined connection.
Types of lubricating compounds
To care for mechanism components, lubricants of different consistencies are used:
- Semi-liquid. Such compositions contain a variety of additives and additives.
- Plastic. They are the most versatile option. Most often used for gear and screw drives.
- Solid. Lamellar suspensions in their original condition.
The special gear composition belongs to the semi-fluid system.
The most popular lubricant for the trimmer is “Calm”. Thanks to the special composition and components, wear is significantly reduced and corrosion resistance is increased. The main properties of this brand of lubricant are:
- oxidation resistance;
- high penetrating ability;
- resistance to high temperatures;
- high adhesion.
Shtil lubricant is suitable for brush cutters and trimmers, as well as for all transmissions with a closed housing.
Malfunctions and solutions
- Strong (or rapid) heating. The main reason is lack of lubrication. If such a malfunction is detected, add lubricant and run the tool in a gentle mode.
- Increased vibration, swaying of the gearbox. The reason is mechanical damage. Eliminated by tightening the housing or replacing it.
- The presence of knocking, play or jamming when the shaft rotates. The causes of the malfunction are destruction of the bearing, damage to the boot. To prevent such defects from occurring, the trimmer gearbox should be lubricated. How and with what frequency to lubricate is indicated in the manufacturer’s instructions.
- Trimmer blade jamming under high loads. The reason is tooth wear. This problem cannot be resolved. A complete replacement of the mechanism is required.
Trimmer lubrication points
To ensure smooth operation and longevity of the mechanism, careful inspection and maintenance should be carried out. An important point is to lubricate moving parts. In most cases these are:
- space from the transition from motors to a straight shaft;
- joint of a straight shaft with a flexible one;
- transition of the shaft with the landing head;
- gearbox
Popular among users is the multi-purpose waterproof lubricant “Litol-24”. The operating temperature range is from -40 to +120 degrees. This lubricant is used in friction units and is effective at elevated temperatures.
Properties of trimmer lubricant
In the production of lubricants, special substances are used that must meet environmental regulations and standards. After production, they decompose without causing harm to the environment.
The consistency of the material initially has an increased level of viscosity, and during operation this parameter decreases. This factor ensures complete penetration and reliable protection of working couples under heating conditions.
Long-term use and uninterrupted operation are ensured by timely and proper care. Various materials are used to carry out care operations. Well-known manufacturers develop their own branded care products. These include: lubricant for trimmers “Husqvarna”, “Champion”, “Makita” and others. Lubricant is added to the gearbox of a gasoline trimmer every 8-10 working hours.
Husqvarna 2-stroke HP l
The special formula of this oil for two-stroke engines is designed for harsh operating conditions. These include serious temperature fluctuations and the use of low quality gasoline. The lubricant includes additives that prevent deposits on structural elements and create the necessary fluidity and viscosity. Can be used for trimmers, chainsaws, and scooters all year round. You can fill it even in severe frosts - the average crystallization temperature of the oil is about 40 degrees.
Using lubricant for a 2-stroke engine will ensure uninterrupted functionality of the equipment even under high heat and in an aggressive working environment. It has improved properties - the composition has stable protective characteristics, minimizes friction, thereby reducing the need for repairs and maintenance.

User reviews of lubricants
Experts advise using only original materials whose characteristics meet the manufacturer’s requirements. If there are none, you should clarify how to lubricate the trimmer gearbox. Experienced users do not recommend using solid oil, because this material is not suitable for the temperature and speed characteristics of the unit, as well as for consistency. Also, the given material does not have anti-wear properties.
The operating temperature range of grease is from minus 40 to +65 degrees, but even with these parameters, during the heating process, the density of the material increases, and the lubricant itself becomes rough. If there is an emergency need to treat the instrument, you can use Litol-24.
Important Feature
The prepared combustible mixture for the trimmer enters the combustion chamber of the cylinder in the form of a whitish mist. The oil liquid integrated into gasoline lubricates the crankshaft and cylinder walls. Not adding enough oil to the fuel can lead to premature wear of trimmer
. Exceeding the norm leads to carbon deposits deposited on the working parts, which also leads to premature technical wear of the brush cutter.
A gasoline mower will serve its owner for a long time, provided that the fuel tank is filled with high-quality fuel rather than any kind of gasoline.
Gasoline trimmer maintenance
Most lawn mowers and trimmers have a flexible shaft in their design. Its condition must be checked at least once every 50 working hours. To perform this operation, you need to remove the tip of the rod, pull out the shaft and inspect it, then lubricate it.
Inexpensive materials are suitable for shaft maintenance; it is more difficult to choose them for the trimmer gearbox. How to lubricate this mechanism depends on the tool manufacturer. It is best to use materials that contain molybdenum disulfide. The latter ensures smoothing and filling of cracks on the working surface, therefore it is especially valued among users.
Important: using a large amount of high-density lubricant leads to overheating of the mechanism, increased friction of working pairs and fuel consumption. Therefore, the process of selecting materials and prevention should be treated responsibly.
Engine starting
ICEs of household mowers are equipped with manual starters. The starter device is simple: a strong cord is wound onto a drum, which is directly or through a gearbox connected to the crankshaft, the start is made by sharply pulling the cord, and the drum unwinds, driving the crankshaft, which in turn starts the engine. More complex models are equipped with an easy-to-start Flash Starter system. This system has a special mainspring, which is twisted through a ratchet by several pulls on the starter cord, accumulating kinetic energy. After which, a special release button is used to release the latch, and the spring unwinds along with the drum and crankshaft. “Easy start” ensures faster start-up and lower energy consumption for the owner. Also, for quick starting, an additional fuel supply to the carburetor is provided with a special button. To supply an additional portion of gasoline, you need to press the button once or twice. The starter gearbox is lubricated with oil intended for lubricating the gearbox.
