A lawn, alpine slides and cute gazebos are what is now most often found in courtyards. But in order for the aesthetic component to be constant and bring widespread pleasure, these elements require constant care and maintenance of a decent level. This is especially necessary for surfaces covered with lawn and various plantings in the form of bushes. Neatly trimmed grass and bushes are a determining factor in shaping the opinion of the owners of the house and the mood of not only its guests, but also people passing by.

Advantages of gasoline models

The starting system for gasoline trimmers is simple and reliable. Thanks to the modification of the engine, using this product turns into a holiday, and the monotonous work of bringing the site into the required form will only cause pleasure. Low noise and vibration levels will ensure that there is no need to use additional effort to hold this tool. Additionally, this factor is enhanced by the shoulder strap provided in the design. The belt is double, and in places of contact with the body it has additional soft linings. This is especially important, since this technique allows you to use the trimmer for quite a long time and process large areas. The petrol trimmer “Stil” has a comfortable bicycle handle, which ensures the correct range of motion and quality of the result. Thanks to the design, its position changes depending on the user's wishes. Almost all control systems, including fuel supply, are located on this structural element, which allows you to use the trimmer without being distracted by unnecessary actions. The design of the cutting element helps to mow grass and bushes of absolutely any length. The glasses included in the kit protect the organs of vision, and the shape of the product makes it easy to carry and transport.

Chainsaw engine does not start

If the mechanism does not start, it stalls immediately, check sequentially:

• is there fuel in the tank;
• serviceability of the spark plug;
• cleanliness of the air and fuel filter;
• cleanliness of the breather and exhaust channel.

It is necessary to refill with a freshly prepared mixture based on AI-92; the oil is injected for precise dosage with a medical syringe. This will help avoid expensive chainsaw repairs.

You need to make sure that the spark plug is working and produces a spark when it comes into contact with the body. In this case, it is necessary to dry the spark plug channel, clean and dry the part itself. You can change the candle, but the channel still needs to be dried for 40 minutes. Check the serviceability of the high-voltage wire; there may not always be contact. A malfunction in the ignition unit when repairing a lawn mower cannot be repaired with your own hands.

If the engine does not stall when the air filter is removed, this is the reason - replacement or cleaning is required. The fuel filter is replaced with great care. After checking the cleanliness of the breather, remove the muffler mesh and clean the exhaust channel.

The next step will be carburetor repair, where you will have to find the fault and fix it, taking into account the tiny size of the parts. If the simplest operations do not bring results, in order not to disrupt the fine tuning of the system, it is better to entrust the repair to a specialist.

Features of work

Before starting work on the site, it is necessary to assess the condition of the plant element. These steps will help you make the right choice of attachment in cases where the cutting tool is replaceable. It is more convenient to mow rare and soft grass with a fishing line, while at the same time, for abundant and dense grass, a knife is better suited. Before use, fill the tank with gasoline and oil. If the tool is new, it is not recommended to perform work at maximum speed before the 3rd refill, in order to prevent early failure and the need to grind in parts for further quality interaction. It is necessary to select the optimal position of the trimmer, and for convenience and quality of the result, you need to divide the area into sectors. After work, the cutting tool must be cleared of grass.

About spare parts

Any instrument needs preventive maintenance. Even professional models need to be at least adjusted, and done correctly, according to the instructions. As for repairs, spare parts for Stihl lawn mowers should only be purchased as original ones. Analogues are unacceptable.

The models described above acquire “diseases” after 4-5 years of operation, but they exist. To protect your expensive instrument from unknown breakdowns, you should follow these recommendations:

1. Read the instructions carefully. It is important to know the proportions for gasoline and oil, and even better to follow them, measuring per 1 liter. exactly 20 grams of gasoline. oils
2. Don't skimp on gasoline. Strictly 92 and above.
3. The easiest way to measure oil is through a medical syringe.
4. The fuel mixture should not be stored for more than 2 weeks because gasoline undergoes oxidation.
5. After purchase, the petrol mower must be tested at maximum power. 15 minutes of work, then 15 minutes of rest. Use this method to produce up to 5 tanks.
6. Clean filters (air and fuel).
7. Avoid getting grass caught on moving parts.
8. Do not bump the disc into fences, stones, trees or other obstacles. Otherwise, engine and clutch failure cannot be avoided.
9. For prevention, lubricate the rigid shaft with lithol-24 once a year.
10. A line break will cause less damage, but this is a working issue. You can continue use by pressing the coil correctly.
11. When cleaning the gearbox, do not immerse this element in a container of water.

The resource of the tool allows you to carry out the necessary work in the garden with pleasure. Having chosen any of the described models, you can safely begin running in the engine and further proper operation.

Security measures

Before starting work, you need to rid the area of ​​large elements, check the condition of the product and put on a protective mask. You should not use knives that are included with a trimmer of another brand; the cutting tool itself should not be parallel to the ground during operation. You should not use a mower, especially an electric one, when the grass is wet or the weather is damp. It is necessary to pay attention to the length of the fishing line. The line for the Stihl trimmer should ensure the mowing process and not pose a danger to parts of the human body, in particular to the legs. During work, you must make sure that there are no other people on the site.

Repair and lubrication of the lawn mower gearbox

The role of the gearbox is to transmit torque from the motor shaft to the cutting tool through 2 toothed gears with different numbers of teeth. Torque is transmitted at an angle of 300. The speed of the lower cutting disk is 1.4 times less than the engine speed. Gears must be clean and lubricated. There is a hole under the screw on top to supply oil to the teeth.

The lawnmower gearbox is lubricated at least once a season. If the work is intensive or there is extraneous noise in the lower unit, it is necessary to lubricate more often.

First, you should clear the area where the plug covers the hole from soil and grass. Unscrew the plug with the appropriate tool, it is included with the saw. We use grease from a tube. You choose either a native lubricant from the manufacturer, or well-known high-quality compounds, such as Oleo-Mas, Litol-24, Azmol 158. Open the protective layer of the tube and lay the instrument on its side. Slowly rotating the knife, squeeze the lubricant into the gear housing. The gears, turning, spread the composition with teeth over the entire surface. You can also add lubricant using a special syringe.

Too little or too much lubrication can cause the gearbox to heat up. An audible knock and play indicate the destruction of the bearing or the ingress of dirt due to damage to the anthers. Bearings must be replaced using a puller, without using the heating method.

If the gearbox wobbles and moves along the rod, it is necessary to replace the housing, or temporarily tighten the assembly with a clamp to secure it to the pipe. If the knife stops rotating, it means that the gears are not engaging - the teeth have become worn out or chipped. The pair will need to be replaced with complete disassembly of the unit.

Disassembly of the gearbox with removal of the shaft and bearing units cannot be carried out using heat. When heated, the metal loses its strength qualities and subsequently the unit becomes unreliable. To remove bearings, use a puller.

When replacing a gearbox, it is necessary to select a new unit, guided by:

• pipe diameter;
• drive shaft diameter;
• drive shaft cross section;
• method of securing protection
