Fuel mixture and refueling

For the convenience of preparing the fuel mixture, it is better to have a special canister, where one part contains gasoline, and the other contains 2-stroke oil. We recommend getting one like this, it is very convenient to use https://ru-sad.ru/prinadlezhnosti-dlya-sadovoy-tehniki/dlya-benzopil/kanistryi/

Next, take a measuring container with a scale applied to it, with its help you can prepare the mixture as accurately and quickly as possible. Look in the instructions what brand of gasoline and 2-stroke oil https://ru-sad.ru/prinadlezhnosti-dlya-sadovoy-tehniki/masla-i-smazki/ are recommended by the manufacturer of your lawn mowers. Pour gasoline and oil into a container for preparing a fuel mixture, according to the proportions indicated in the instructions. Then carefully pour the prepared mixture through a funnel into the trimmer fuel tank. The ratio of gasoline to oil should be exactly as indicated in the instructions. This is a very important point!

Starting lawn mowers with cold engine

To start the lawn mower for the first time, locate the choke lever and set it to the “closed”. Turn on the ignition on the handle. If your model has a manual fuel pump, popularly called suction, then press it 3-5 times until you see the fuel mixture inside the primer. The tool is now ready to run. Place the trimmer on a flat surface to ensure a stable position. Pull the starter rope gently until you feel its resistance, and then pull the rope towards you with a sharp movement 3-5 times.

If the engine starts after 5 jerks, open the choke. If this does not happen, open the air damper anyway (if the damper is open and you continue trying to start the engine, the fuel will flood the candle and you will have to dry it, and this is a waste of time).

If the engine does not start when the throttle is open, close it and continue pulling the cord. The first launch can be quite difficult and require up to 15 jerks. After the engine has started to work, press the throttle lever once, so you engage idle. Now let the engine run and warm up. After that it can be stopped by pressing the button. “Stop”.

  2. Buy oil for this type of motor. Gasoline for the trimmer. Ai-92/93/98, sold at all gas stations.
  3. Mix oil with gasoline. Mineral oil is mixed in a ratio of 1: 34 with gasoline, synthetics. In 1: 50. Follow the trimmer manufacturer’s recommendations for oil viscosity (see the label on the flask). All-season oil 5W-30 is used more often. Do not use untested car oils.
  4. Pour a small amount (for example, 0.5 liters) of the resulting fuel into the tank.
  5. Close the air damper by sliding the desired lever (see instructions).
  6. Turn the ignition key (or handle) to the “on” position. Otherwise the trimmer will not start. Beginners often make this mistake.
  7. Pump some fuel into the carburetor. If there is a manual “rocker” with a separate button or lever (see instructions). It takes 4-7 clicks.
  8. Place the trimmer on a level surface.
  9. Pull on the starter cord gently until you feel it slow down. Then pull it out sharply, but not completely. Repeat this movement up to 4 more times.
  10. If the engine does not start, open the air damper again, otherwise the candles will flood with gasoline with further movements of the cord. Perform 2-3 attempts to start the engine with the handbrake open.

Preparing for the first start of the lawn mower

Before you start the lawn mowers for the first time, you must perform a number of sequential actions:

  • Inspect the gearbox and lubricate it;
  • Prepare the correct fuel mixture.

First start-up and running-in of lawn mowers

Correct initial start-up and running-in of a lawn mower are very important steps in getting started with a new tool. On the one hand, they allow you to preserve the service life of a gasoline engine, laid down by the manufacturer, since at this stage, the grinding of moving units and parts takes place. On the other hand, the first necessary skills of working with a trimmer are acquired when it comes to the first tool in life.

  • Preparing for the first start of the lawn mower
  • Inspection of the lawn mowers gearbox and its lubrication
  • Preparing the correct fuel mixture
  • Starting the trimmer for the first time
  • Let’s start running lawn mowers

Inspection of the lawn mower gearbox і yogo mastilo

It is necessary to rewrite the gearbox before starting the gasoline trimmer on a permanent basis. The visibility of the mast, or a small number of build-ups rubbing the gears of the gearbox, is good enough to reach high speeds. The result is overheating of the gears. Operate the lawn mower gearbox in a row. Before the appearance of such a breakdown in the process of victoriousness and additional help for a post-war period.

In case of emergence, before the start of the gasoline mow, the required amount of oil is put into the gearbox or in the hull, “LITOL” is put into the housing. For the whole, it is necessary to turn the screw and sprinkle “LITOL” in a 1-2 ml bottle on the vigy gear case.

Why the lawn mower won’t start. Troubleshooting

Caring for a personal plot, summer residents periodically encounter the fact that the lawn mower does not start. There are many reasons for tool failure. For the correct diagnosis of the problem, the owner of a useful unit in the country needs to know the device and the principle of operation of its individual parts.

Lawn mowers filter diagnostics

Another reason why the gasoline scythe stalls is the air filter. To eliminate it, try removing the filter and starting the trimmer without it. If possible, then you will have to change the air filter to a new one, or at least blow through and thoroughly clean the old one.

The petrol trimmer may not start if the fuel filter is dirty. This is the next step in our algorithm. Here we check the condition of the filter element and, if necessary, replace it with a new one. When replacing, try not to leave the suction pipe completely without a filter, this is prohibited by any operating instructions. Haste can turn into repairing the engine piston group.

Complex reasons for lawn mowers failure

If the step-by-step troubleshooting algorithm does not work, and your scythe still does not start or stalls, it is worth inspecting the carburetor and the engine itself. A clogged carburetor can be one of the reasons for erratic tool performance. There are three main problems here:

  • Clogged ducts or nozzles. All this is cleaned by special washes or blown by a powerful jet of compressed air from the compressor. Do not use needles and wires, as the bore may be damaged;
  • Worn carburetor gasket. Exit. Replacement of a failed gasket;
  • Violation of tightness. To check this indicator, you can use an ordinary household tonometer, replacing it with a suitable pressure gauge. Watch the readings: if they do not change, everything is fine, and if the pressure starts to drop, then some part of the carburetor is faulty. We’ll have to find it and replace it with a new one.

If everything is in order with the carburetor, then the petrol trimmer may not start due to wear of the piston group. If chips, scratches or scuffs are found, the piston or cylinder should be replaced. Piston rings are subject to mandatory checks. A small backlash of the piston when rocking the connecting rod indicates that it is time to change the rings. It is best to entrust this procedure to the specialists of the service center.
