The human tendency is to ennoble the place where he spends the lion’s share of his time Residents of cities resort to the services of designers, or try to change something in their homes, buy new furniture, wallpaper, so that, coming home after a hard day, you can mentally relax and unwind in a comfortable environment. Residents of their own homes, located outside the city, have very different concerns and requirements. Mow shrubs, grass, various dead wood, carefully monitor the condition of the garden and yard. It is clear that this requires somewhat different means of achieving comfort. And here at the forefront of the new brainchild of engineering. mowers.

Repair of any machine has to start with preparatory work, and the STIHL 180 is no exception. The first preparatory step before any STIHL 180 chain saw disassembly involves removing the side cover, chain and guide bar from the chain saw. Next, using a compressor and a brush, you need to clean the chainsaw of dirt, sawdust, oil stains, and other things.

in the chainsaw cleaning process, special attention must be paid to the chain saw chainwheel, because the chainwheel is located on the chainwheel’s drive sprocket. к. this is the dirtiest part.

In places where there is a large accumulation of oil, you can flush it with clean gasoline.

Boom and power tool drive

The boom has two very important functions: 1. it forms a rigid frame of the entire structure, 2. inside the iron hollow rod passes the shaft, which connects the working body to the engine. According to the appearance of the boom you can find the class of the tool, if the rod is bent. it is comfortable to work, but in this case the drive is a flexible shaft, which can not transmit a large torque. If the boom is flat, a rigid iron rod runs inside, it is much more reliable and can transmit more torque. Because the professional tool always has a straight boom.

Occasionally, intensive mowing grass trimmer begins to grind and make unpleasant sounds that indicate a lack of lubrication gearbox. The implement is the most heavily loaded component, so it wears out the most quickly. If it is not oiled in time, the actuator can seize soon!

Procedure for pre-lubricating a gearbox

There is no need to disassemble the gearing before lubricating it. In the device is already built a special hole for this purpose (it is shown in the photo below)

In addition to the gears, during the lubrication it is necessary to pay attention to such elements of the mechanism:

Pour oil or solid lubricant through the grease fitting with a screw. At the same time perform actions in the following sequence:

  • Clean dirt and grass clings from the gearbox housing, especially the area around the plug to prevent debris from entering the mechanism;
  • unscrew the plug using a suitable tool (often it is included with the trimmer);
  • into the open technological hole, the selected lubricant is injected from a tube or using a syringe, as shown in the photo below
  • screw the plug in place.

when applying grease you need to rotate the knife, so that it is evenly distributed on the teeth of the moving gears.

If for any reason the gearbox has to be dismantled, the old lubricant must be completely removed from all surfaces of the gears and housing, the shaft, and only then the new one should be used. It’s easy to lubricate the disassembled mechanism with solid lubricants.

The entire process of lubricating the gearbox is demonstrated in the video:

You should lubricate the transmission unit at least once a year, but it is recommended to do it every 20 hours of heavy trimmer use. If the first signs of malfunction with the mechanism appear, it is necessary to apply the lubricant as soon as possible.

Types of grease used

Factors to consider when selecting a lubricant are:

Well-known manufacturers, such as STIHL, Husqvarna and others, in addition to trimmers, also produce grease for them. This product not only reduces wear and tear, but also protects the gear metal from corrosion. That’s why it’s better to use the same lubricant products for these brands of brushcutters.

If the composition used for lubrication has good adhesion, it is practically not squeezed out of the gearbox through the gaps.

Different models have different grease consumption rates. This is determined in large part by the intensity of use of the trimmer and the heat of the transmission mechanism. The lubricant is considered sufficient if the temperature of the gearbox during operation does not exceed 40° C.

The consistency of grass trimmer lubricants can be:

In terms of composition, the following types of grease are in demand:

  • graphite which significantly reduces friction to improve pinion rotation;
  • Lithium soap greases, which also have excellent corrosion protection and are enriched with metal enhancing additives that do not contain any harmful substances;
  • Universal, containing highly refined mineral oils and performance-enhancing components.

Examples of suitable lubricants are: Champion EP-0, Gear Grease OREGON, Oleo-Mas, Azmol 158, Lithol.24

After the melting of the snow cover with the first days of spring grass begins to appear, which cheers up with a tender greenish cover.

Naturally, to combat weeds can be used an ordinary scythe or sickle, but it is long and labor-intensive, and cut grass becomes ugly.

Starting the engine

The internal combustion engines of household mowers are equipped with manual starters. The starter device is simple: a strong cord is wound onto a reel, which is directly connected to the crankshaft or via a reducer, and the cord is pulled sharply to start, while the reel is unwound, setting in motion the crankshaft, which in turn leads to the start of the motor. advanced models are equipped with the Flash Starter easy-start system. In this system, there is a special winding spring, which is twisted through a ratchet by several pulls on the starter cord, accumulating kinetic energy. After that a special button of release is released from the detent, the spring is unscrewed together with the drum and the crankshaft. “Easy start” provides sharper starting and the least amount of energy required by the wearer. Additional fuel injection into the carburettor with a special button is also provided for quick starting. Push the button once or twice to get more gasoline. Gear reducer is lubricated with oil designed for gearbox lubrication.

On mowers driven to a trimmer with working attachments, a transition cone gear is provided. Transmission of torque is via bevel gears. There are two types of gearboxes: maintained and unmaintained. Gears are nicknamed maintenance. the ability to add lubricant to the working space for lubrication gears. If the gearbox is not serviced, then the lubrication is laid down by the factory.The gearbox is factory lubricated for life and has a hermetically sealed housing. According to the opinion of the developers of the manufacturing plant, such measures increase the service life of the gearbox, because contamination does not get inside through the lubrication hole which is not tight. Gearbox of lawnmower is the most loaded part, transmitting force with the configuration of the direction, therefore the node is very important proper maintenance and correct lubrication, what kind of lubrication is needed for the gearbox and repair of cone gearbox with= replacement of bearings you can see the roller below.
