How to start a gasoline grass trimmer without a starter?

As always, this happens at the most inopportune moment.

A chainsaw is a thing that almost everyone owns these days. Can’t do without it in the countryside. over, if the yard is a large farm, the use of lawn mowers every day during the season can lead to wear and tear more than one rotor and burn more than one hundred liters of gasoline.

Even with this high wear and tear, a properly maintained and well-lubricated mower can go a full season without any damage.

However, a lawn mower, like any other machine, has its drawbacks, which show up during the rainy season or when the grass grows too fast. One of these weak points is the starter motor. When you start the mower, it is subjected to a high load that it is normally designed for. However, a peculiarity of the two-stroke engines fitted to lawnmowers is that if they are not optimally set or fail to start, a strong recoil can occur. The stresses that the starter must withstand in this case are too great for it. As a result, the strings may break or the plastic may break as a result of the subsequent jerk at startup.

It always happens at the most inopportune moment.

Of course, in this case you can go to the store and buy a new starter. But people rarely live near such a store. usually you have to drive 20, 30 or 50 km (or even more) to it. So in this situation you can start the chainsaw without a starter motor as follows.

The chainsaw’s motor shaft does not need much power to rotate. If you use a torque wrench to check the required tightening torque, it will show 0.

That means you can use any low-powered motor, like a drill, to get the engine up to speed.

A drill can start a scythe with no problem. You can see it more clearly in the video.

Motocross differs from the grass trimmer in that the grass trimmer is not a hair growth trimmer line, but a mechanical gearbox or winch based on gears equipped with a blade. The blade drive is much more powerful than the logging mechanism. When cutting bushes also use a heavy-duty hedge trimmer. Both Chinese and European lawn mowers are no different when the claimed power is real.

Toothed or solid oil is used to lubricate the gear wheels. After checking the gearbox, be ready for the engine itself. According to the instructions above. If the start-up fails, the problem is already in the engine.


Nowadays, lawn mowers are available in two main types: electric and gasoline.

Very convenient when mowing grass at a distance from home. Their main advantage is mobility, because they are not tied to a particular place, you can move to the farthest corner of the site and work there. Gasoline mowers are much more powerful than electric ones and can mow for many hours without interruption (does not affect the engine). Gasoline lawn mowers have several times the speed of mowing the grass along with electric mowers.

Before turning on the gasoline mower, you should first check the presence of fuel and lubricants, and most importantly. oil, because if it is absent or insufficient, the engine may jam during operation, and you will have to spend a lot of money for repairs.

They are less noisy than petrol mowers and are cleaner (environmentally friendly) and more economical to use (especially if electricity bills are inexpensive). The main disadvantage of such a mower. it is limited mobility by connecting the cord to the power source, and the extension cord is often tangled and clings to everything.

Before starting the electric lawnmower, you should first check whether the extension cord and the power cord itself, as well as the functionality of the socket are not damaged.

Another very important thing for an electric mower. Never use it when it is wet or raining. It should only be used in dry, moisture-free areas.

The most frequent breakdowns of machinery

Lawn mower sometimes does not start well, and this is influenced by many factors. For example, does not start the mower Husqvarna, McCulloch lawn mower STIHL for almost the same reasons.

Ignition, carburetor, filters are the main problem. If after checking it turned out that the fuel is good quality in the right amount and the air damper is closed, then the lawnmower sometimes does not start well for reasons:

Spark plug is defective, flooded. In this case, the candle is unscrewed, dried and cleaned with a file, file. It is recommended to drain the residual fuel and dry the hole for the spark plug. Then insert the gap to a distance of 1 millimeter and screw the spark plug in. You need at least 30 minutes for channel drying. Connection on the threads is dry. It is necessary to lubricate with petrol. this will help the spark to ignite. No spark from the plugs. Need to check the spark plug contacts and wires. The unit makes popping noises when contact is normal, and it stalls, which means there is a problem with the ignition. In this case, the user is better to contact the service center. The presence of clogging in the air filter. It is recommended to remove the broken part and try to start the unit without it. In case of a stalled engine, it is necessary to clean or change the filters for new. Fuel filter clogging. The way to solve the problem. inspection of the filter element, its replacement

Watch out for leaks! It is not necessary to operate the technique without filtering elements. Dirty breather plug. It regulates the pressure level in the gasoline tank

If the breather plug is blocked, it creates a vacuum and fuel stops flowing into the device. Serious breakdowns at which the technique can overheat and it is necessary to address to the experts: Presence of contamination of jets, channels in the carburetor. Solution. flushing the mechanism with special fluids, blowing the carburetor with air jets. Worn gasket. It is enough to replace the part with a new one. Damaged sealing. Diagnose with a tonometer. If the pressure is stable, all is well with the carburettor, but if it drops over time, you need to find the damaged part and replace it as soon as possible.

How to start a grass trimmer without a starter electric screwdriver

It often happens that the starter on the trimmer fails, the Chinese mowers because of the quality of parts because the price is low, and the elite trimmers because of the “steady hands” or the expiration of a large amount of time in operation.

Anyway, the grass trimmer can be started without a starter with an ordinary electric screwdriver and head.

If you can not save the starter, then rip out the starter all the innards and cut a hole in the center for the head, and screw the starter housing back.

That should do it, but it’s much more accurate than the picture

Reasons why a new grass trimmer does not start

It’s not just older brushcutters that have had problems starting, but also brand-new brushcutters. In this situation there is only one way out. to listen to the advice of our experts and use their practical experience!

The reasons why the new gasoline trimmer for grass does not start, eliminates the instructions for starting a brushcutter from forum members, which sounds like this:

  • Switch on ignition.
  • Pump up the fuel with a silicone button (primer) located at the bottom of the carburetor. It is necessary to do as much (or a little more) than it is written in the instruction, usually about 8-10.
  • Close the choke.
  • Hold the gas pedal lever with the stop button at high revs.
  • Pull the starter handle 2 or 3 times. The engine should “grab”.

If engine “seized” and stalls, it is necessary to move air valve in 1/2 position and try to start the engine again. If the engine is running, turn off the throttle and turn the choke to the “open” position. The grass trimmer starts easily. Let’s get to work.

While handling the fuel you don’t have to be afraid of overflowing. If this happens, and “filled the plug”, then unscrew it, it is enough to move the air damper in the “open” position and holding the full throttle, and simultaneously scroll the engine with the starter 2-4 times. After that you can start the engine and mow grass without fear that it will stop.

For the continuous operating time please refer to the instruction manual of the grass trimmer. On average, we mow for 15-20 minutes, after which it is necessary to stop the grass trimmer and let it cool down for 3-5 minutes. Also the weather and operating conditions have a significant impact on the duration of continuous operation. In hot weather, when mowing high grass, weeds, under heavy load, grass trimmer quickly overheats, does not work and hardly starts after a break.
