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.

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.

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.
Not the best lubrication option. Not much different from low-budget “graphite”.
The key to long-term operation of any mechanism is correctly selected and high-quality lubricant. Now there are many similar products on the market and price is not always an indicator of quality.
It is more difficult to choose a lubricant with a narrow focus because There is less demand for them and sellers do not like to stock their warehouses with them.
After purchasing the trimmer, 3ton gear lubricant was purchased.
3ton gear lubricant
Packaging: 100 gr. cost 250 rubles. For this level of lubrication it is expensive, but when purchasing a trimmer the required manufacturer was not available. I had to go to the construction market and with great effort find at least some kind of lubricant for the trimmer gearbox.
In fact, this lubricant turned out to be a scarce commodity, and as soon as I was offered 3ton, I immediately bought it. Although I’ll still change it to a more worthy option later.
The lubricant was produced in Russia in the Moscow region.
In fact, this company is not bad in terms of car care cosmetics, but I would not buy it for lubricating equipment.
Since the trimmer was practically without lubrication, I decided to take a chance.
By the way, this lubricant can be used for gearboxes of motorized drills, i.e. it is capable of operating at both high and low speeds.
The price is still too high because... for 200-250 rubles you can purchase high-quality lubricant from a reputable manufacturer.
Let's move on to printing and use.
Removing the protective cap we see a cone-shaped proboscis.
Opening the tube (you have to cut it) The budget of the brand immediately affects it because... Without an additional tool we will not be able to open the tube. In more expensive models, the tube is opened using the reverse side of the closing cap.
By the way, each trimmer brand focuses on its own brands of oils and lubricants. This is done specifically to sell their products. In fact, you can use any brand of lubricant. The main thing is that they fit within the tolerances.
I wasn’t too lazy and found an old lubricant from a well-known brand. In my opinion, this is the best option for the operation of the mechanism. In other words, the superiority of one lubricant over another is even visually visible.
In the case of 3Ton, there was something inside that strongly resembled CV joint grease interspersed with graphite. Even the smell is the same. Of course, I didn’t do chemo. analysis, but with 98% probability I can say that inside the tube there is ordinary lubricant for angular velocity joints.
Compared to normal lubricant
As a result, we are convinced that we overpaid even more because... A CV joint costs just a penny.
The lubricant is pumped conveniently due to the conical shape of the nozzle.
The lubrication procedure is simple. We fill the lubricant, rotate the shaft and fill it with more. When the gearbox is removed, grease may ooze out from the back side. This is not even bad because... In this way we displace the oxygen plug from the gearbox.
Gearbox packing The brush cutter shaft itself was also coated with this lubricant. It is ideal for this purpose.
What's the result?
Initially, I mowed 12 acres. The lubricant in the gearbox did not leak and remained almost at the same level. The only thing is the gearbox is noisy. I can’t say for sure whether this is due to low-quality lubricant or manufacturing flaws (the braid is new).
By and large, this is an ordinary “graphite” and there is no point in overpaying for it.
I am using it as a temporary option and will soon replace it with a more worthy sample.
If this lubricant had a price of 80 rubles, then I could recommend it, but for 250 it makes no sense to buy a regular graphite lubricant. Therefore, 3ton is good as a car cosmetic product. For lubricants and oils, I would prefer something else.
Advantages
relatively convenient to pump into the gearbox
Flaws
- regular graphite grease
- price

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.
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.
Terms of use
The use of lubricants for a 4-stroke model is not particularly difficult - you just need to fill a special tank and constantly monitor its level. Another thing is 2-stroke copies. For them, you need to first mix the oil with gasoline, and only then pour it into the trimmer, but under no circumstances add it separately to the gas tank - otherwise the trimmer motor will not receive effective lubrication and will break down.
When diluting, the proportions must be strictly observed. In this case, the ratio of components is regulated by the type of oil, conditions and manufacturer’s recommendations. For example, mineral oil is characterized by mixing in the range of 1:25 - 1:35, and for synthetic oil - from 1:50 to 1:80. Dilution must be carried out in a separate container by adding oil to the required amount of fuel. And only after the ingredients are completely mixed, the mixture is poured into the gas tank.
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.
Drive motors
Most mowers are equipped with a gasoline engine (ICE), it can be two-stroke or four-stroke, there is no particular difference between them. The four-stroke is more economical and powerful, but more difficult to maintain and more expensive to repair. The two-stroke is easier to maintain, cheaper, but low-power, consumes more fuel, and has a dirtier and noisier exhaust. There are also combined engines. In addition to gasoline engines, trimmers can be equipped with electric motors that are connected to a 220V household network with a long cable, but, as a rule, these are household devices that are connected to the power supply wires.

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.
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.
