Trimmer Is Not Gaining Momentum

The gasoline trimmer is NOT gaining momentum: the reasons and features of repair

Trimmer Is Not Gaining Momentum

To cut grass on a small lawn, it is not necessary to purchase an expensive and bulky lawn mower; it can be easily replaced by a gasoline / electric trimmer. The device of THESE machines is quite simple, they are easy to use and unpretentious in maintenance. But sometimes problems do occur. About one of them. When the trimmer is NOT at maximum RPM. Speech and will go in this article.

Troubleshooting methods

The first three reasons are fairly easy to eliminate. If the matter is in the mixture, you need to pour out the old fuel from the tank, prepare a new emulsion from high-quality gasoline and engine oil (if your engine needs a mixture) and pour it into the fuel tank. If the trimmer is running on pure gasoline, it’s still easier.

In the second case, it is necessary to carefully free the trimmer parts from the wound grass.

The last reason a lawn mower doesn’t work properly will require a little more familiarity and skill from you.

In order to properly adjust the carburetor for lawn mowers, a specific procedure must be followed. First, clean the air filter thoroughly. The easiest way is to rinse it (it is advisable to sprinkle water on the filter regularly after 9-10 hours of operation).

After that, in the diagram of your trimmer, which is in the operating instructions for the device, find the adjustment screws. There are usually three of them: the first is responsible for supplying fuel, the second. At idle, but the third is designed to limit the number of maximum engine speed.

Next, turn on the unit and wait for the engine to warm up.

Tighten the first (fuel mixture) adjusting screw slowly. Catch the moment when the motor starts to stall and turn the propeller back 45 degrees. If you didn’t have time and the motor stalled, the screw should be returned 90 degrees. Open the throttle and watch the revs increase. Next, slowly unscrew the screw (each turn. The same 45 degrees) until the moment when, at full throttle, the engine begins to firmly give out maximum revolutions.

The second screw, as mentioned above, controls the engine idle speed. By loosening it, you reduce the number of revolutions, twist. You increase. The screw needs to be adjusted so as to ensure reliable engine operation at low revs. For better starting speed up the engine slightly. At the same time, make sure that the motor makes several tens of revolutions by the beginning of the movement of the knives / reel with line. If the engine starts poorly, tighten the screw a little.

After you have adjusted the first two screws, test the operation of the device at maximum engine speed. If necessary, you can limit it (maximum). This will protect the motor from “boiling”. To do this, you need to tackle the third screw. Unscrew the locking nut until the adjusting screw can be safely returned. To increase the maximum number of revolutions, the screw must be loosened to decrease. On the contrary, it will spin. Fix the position of the screw with a nut. Test the motor again.

Remember to adjust the carburetor. Not a final procedure. During the operation of lawn mowers, you will most likely have to tinker with it more than once, because the carburetor is unbalanced. This is both increased fuel consumption and quick failure of the spark plugs, not to mention a decrease in the power and performance of the device.

The reasons

Trimmers are reliable and durable (provided they are properly maintained, of course). Most often, malfunctions occur due to contamination of structural elements.

If the motor of your lawn mower Will not start, and does not pick up speed, and does not reach the power you need, or suddenly stalls, a prerequisite may be:

  • Poor quality fuel (fuel mixture), the case may be in long-term storage or in non-compliance with the recipe for preparing the mixture;
  • Grass is wrapped around the shaft of the fishing line / knife;
  • Clogged air filter / muffler;
  • Carburettor imbalance.

Little tricks

  • If you fail to tighten / loosen the adjusting screws normally, it may be that the spring is too thick and stiff. Then you can choose instead of her a more suitable.
  • If your unit requires NOT pure gasoline, but its mixture with engine oil, strictly observe the proportions specified in the operating instructions. There is one little thing: the recommended ratio. 1:25 (for all brands of oil) or 1:50 (for “native” oils). Try the first ratio first. If, with such a recipe, oil drips appear on the motor, and Strong carbon deposits form on the candle, Reduce the fate of the oil by half. This usually helps to fade traces and reduce the amount of carbon deposits.
  • To clean the spark plug electrodes from combustion products, you can use fine-grained “sandpaper”. Wipe them with a dry cloth first and then gently sand them with sandpaper. If the space between the body of the device and the insulator is also clogged, a regular unbent paper clip can help clean it. To do this, briefly soak the candle in diesel fuel, and then scrape off the dirt. If the blockage is small, one procedure is sufficient. Sometimes it is necessary to repeat it several times in case of heavy dirt. After complete cleaning, the candle must be wiped dry from the remaining diesel fuel, and then it can be used as directed.
  • Please note that foreign-made lawn mowers (gasoline, electric or battery) require a little more maintenance than domestic ones. In particular, many insist on entrusting the adjustment of the carburetor of a two-stroke engine to professionals, especially if your purchase has not expired the warranty period.
  • And finally, one more tip: follow all the manufacturer’s recommendations for the operation and maintenance of the device. So you extend its smooth functioning.

You will learn more about what to do if the petrol trimmer is NOT picking up speed.

Why does the trimmer speed drop?

There are a number of different reasons for this common problem. While working with the device, one can encounter both obvious malfunctions, the signs of which are clearly traced, and asymptomatic cases. The first option is the most simple from the point of finding the problem. If the trimmer does NOT pick up speed, and there are no clear signs of breakdowns, then you will need to consistently check the most common cases of malfunctions, and if the cause is found. Eliminate her.

If everything is in order with the electrical equipment, then we check the carburetor.

Vacuum Carburetors are installed on the trimmers. When disassembling, cleaning or washing it, you need to be extremely careful. Never disassemble the underside of the carburetor where the primer is located. The air filter (visible when you remove the protective cover from the carburetor) must be washed with detergents. The best thing. For dish washing. After drying, put it back. Flush the carburetor with clean gasoline and blow all openings with a pump. Rinse the fuel lines filter, then dry and collect everything. Usually, after all the manipulations, the trimmer starts working.

A thin cable instead of a fishing line, is it worth putting it on the lawn mower?

This idea comes to mind to almost everyone who had to mow 10 acres of tall grass. At first glance, the idea seems like a good one. The cable is stronger than the line and does not wear out so much. However, not all so simple.

The trimmer loves cleanliness. It is necessary Keep the air filter and fuel clean. Gasoline bought at a gas station should be left to stand for 2 days and passed through a simple filter. A piece of baikovy matter.

We check the electrical equipment as follows:

1. Unscrew the candle, inspect the gap between the electrodes. We set the correct gap between the electrodes in the “Dedovsk” way. Take the razor blade, break it in half and insert a homemade probe between the electrodes. If the blades fit tightly, then the gap is perfect.

2. Put the high-voltage wire cap on the candle and lean the candle against the metal surface of the engine. We pull the starter several times. If the spark hits one point well, then the gap is adjusted correctly. If not. The spark is weak or “wandering”, it is necessary to re-adjust the gap between the electrodes.

Why the Chinese lawn mower is NOT developing momentum?

The trimmer does NOT gain momentum, a very common problem and of course does NOT always have the usual solution.

Also, the ignition coil may be punctured in electrical equipment. In this case, the lawn mower Will not start or will start and work intermittently, and then stalls, or on a “hot” does not start at all.

You can check the coil’s serviceability in the same way as when checking a spark: unscrew the candle, lean it against the trimmer body. If there is a spark during the jerk of the starter, or it appears every other time. Need to change the coil.

You bought yourself a new petrol trimmer and immediately got into trouble with it. It starts very badly. If you mow a little, and then turn it off, then turning it on “hot” is an even bigger problem than “cold”. What to do with him, I don’t know how to get it right?

The instruction for the lawn mowers plant sounds like this:

1. Switch on the ignition.

2. Pump up fuel with a silicone button (primer) located on the bottom of the carburetor. Pressing must be done as much (or a little more) as written in the instructions, usually about 8-10.

3. Close the air damper.

4. Fix the throttle lever with a stop button at high rpm.

5. Turf the starter handle 2-3 times. The engine should “grab”.

If the engine “grabs” and stalled, then you need to move the choke to the 1/2 position and try to start again. If the engine starts, then we release the gas and move the air damper to the “open” position. Getting started.

When performing manipulations on pumping fuel, do not be afraid to pour it over. If this happened, and, as they say, “a candle was filled”, then you do not need to unscrew it, it is enough to move the air damper to the “open” position and, while holding full throttle, simultaneously turn the engine with a starter 2-4 times. After that you can start the engine and get to work.

Filters

A clogged air filter is another reason for the unreliable operation of the device. To check the involvement of this element in the malfunction, you need to start the lawn mower without it. A dirty filter can be washed in gasoline, dried or replaced with a new one.

A clogged fuel filter DOES NOT let fuel into the cylinder, and the engine stalls at full throttle due to an elementary shortage of gasoline. This element is located inside the tank on the intake hoses. To eliminate the problem, instead of the old filter, put a new one on the hose or thoroughly rinse the one that was removed.

The trimmer does NOT gain momentum. What to do

Any person who owns a summer cottage or land plot is well aware of the problems of dealing with excess vegetation. Now a trimmer has come to the rescue, which has successfully replaced the usual braid in this field. This unit is very convenient in operation, but it, like any mechanism, tends to fail due to difficult working conditions or incorrect operation. Situations where the trimmer does NOT pick up speed are quite common. To understand this problem, it is necessary to understand some aspects related to the operation of the apparatus.

Carburetor

This mechanism is an important trimmer unit. In order for the carburetor to work properly, several conditions must be met:

  • Disassemble and clean it from time to time;
  • Adjust the idle speed according to the instructions;
  • Refer to the help of the wizard when adjusting.

In the event of a breakdown of this unit, you can do its repair yourself, but only if you have certain knowledge.

One of the reasons for poor carburetor performance is a loose cable. To eliminate the problem, you first need to disassemble the entire assembly, and then thoroughly rinse all the parts, lubricate and tighten the cable, but not very much, so as not to stretch.

Motor

The engine is the most important part of any machine. There are several reasons for ICE breakdowns:

  • Incorrect proportions of oil with fuel (for two-stroke)
  • Old fuel mixture;
  • Wear and tear of the piston ring;
  • Scratch marks on the cylinder and piston;
  • Wearing the device.

All this leads to the fact that the engine either does not start, or stalls.

When to contact the workshop

If the device is under warranty, at the first sign of incorrect operation, it can be safely taken to a specialized workshop. The repair will be done free of charge, regardless of the nature of the damage, if it happened through no fault of the owner. In case of engine breakdowns, a person who is ignorant of technology is better off immediately contacting a specialist. In any case, the severity of the unit malfunction is determined by the user.

Summarize. Both gasoline and electric trimmers are built to provide years of reliable performance. Most of the problems described above are due to insufficient attention of the owner to his assistant. Subject to strict adherence to the manufacturer’s requirements and regular maintenance, the hand mower will work rhythmically and without interruption.

External factors

Several factors, not related to its breakdown, affect the decrease in the speed of lawn mowers:

  • Filter contamination due to the ingress of dirt and dust particles;
  • Use of low-quality fuel;
  • Incorrectly prepared mixture (relevant for trimmers with two-stroke gasoline engines)
  • Contamination of the muffler mesh with vegetation particles, soil elements and other objects.

over, in the second and third cases, carbon deposits form in the combustion chamber, and the carburetor elements become clogged.
