Buying any equipment is a lottery, but much also depends on the gardener. In the caring hands, the Chinese samples serve for a long time and do not let their owners down at the wrong time. And if you forget on time lubricate the gearbox mowers, do not clean the filters, use cheap low-quality gasoline, then garden equipment from the most famous brands will become a headache.
Gearbox lubrication of the trimmer is one of the most important elements of the maintenance of the gasoline trimmer, which must be carried out directly by the user.
Time and order of the prevention gear.
I recommend in the necessary order to carry out the prevention of new gasoline trimmer immediately after purchase, with the addition of lubricant in the gearbox. With all the high cost of gardening equipment, some manufacturers save and put lubricant only at a minimum, at the time of running.
How often lubricate the gear mowers?
Often a routine inspection of the gear with the addition of a liquid grease is carried out once a year at the beginning or end of the season. If the gas trimmer is not used in professional volumes, this is sufficient.
With large amounts of mowing, lubricate the tractor mowing machine is necessary every 20-50 hours of work. If the conditions of the garden equipment are massive, for example, a large field is mowed at a time, and the trimmer does not have time to cool or cheap lubricants are used, then the oil should be checked and added every 20 hours of operation.
Indirect evidence that it is necessary to lubricate the gearbox can serve as overheating or increased the noise of the unit. In these cases, if during the inspection it is found that there is enough lubrication in the unit in volume, I recommend replacing it as a whole, and it is advisable to choose another manufacturer of auto chemical goods. Also, a complete replacement of the lubricant, with disassembling and washing the node, I recommend when buying a used gasoline trimmer.
Grease for gasoline trimmer gearbox.
According to the instructions, a unique transmission fluid grease should be used to lubricate the bevel gearbox. As a rule, manufacturers of garden equipment produce and recommend the chemistry of their brand, as the most adapted to their devices.
At the same time, to reduce the cost of operating garden equipment and increase the attractiveness of the brand of auto chemistry, a lubricant for garden equipment is usually produced multi-functional. It is designed not only for the lubrication of gasoline trimmers gearboxes but also for the processing of hoses, gears, and gearboxes of any garden equipment and mechanical devices operating under high loads.
Even if the specialized lubricant for the gearbox is almost fully developed during operation, the additives still create a compelling lubricating protective film on the surface of the gears.
It should be noted that many owners of mowers in the former CIS for the lubrication of the gearbox use ordinary Litol-24 or lithium-based lubricant for Shrews. It is convenient to refill the gearbox with a 5-cubic medical syringe. Many motorists, instead of a side screw, pick up the thread and screw in a grease press from cars that have served their time. This refinement allows for the addition of Litol without disassembling the assembly with a grease gun.
The undoubted plus of using Litol and lithium-based lubricants for filling the transfer of the mowers is the cheaper operating. But some nuances make spears break on the forums of gardeners in the Internet space. My thoughts on what can be lubricated with lithium-based lubricants, and what is not, read the article “ Litol as a grease “.
How to lubricate the gear motor mowers, gasoline trimmer?
For safety reasons, to avoid accidental start, all maintenance work on the trimmer is necessarily carried out with the electric cap/plug removed from the candle. Do not turn the trimmer over to avoid gasoline leakage.
We unscrew the side screw on the trimmer gearbox. Depending on the manufacturer of the garden tool, instead of a hexagon screw, there may be a turnkey bolt, more often on 17. The thread is plain, unscrew it counterclockwise. Do not lose the sealing washer.
If the lubrication screw is not visible on the inner end of the screw, then 3–4 grams must be added. Scroll the gear by hand, changing the direction of rotation so that the lubricant is distributed over the gears. Repeat the operation several times. On average, the gearbox includes about 5. 10 g. The assembly must be filled with lubricant, taking into account the installation of the screw. Then replace the screw by tightening it tightly.
As we see, it will not take much time or special skills to lubricate the gearbox on a trimmer. Usually, we are going longer than doing the entire amount of maintenance work.
