The Trimmer Coil Is Spinning At Idle

General overview of the petrol trimmer Patriot PT 2540

The Patriot PT 2540 device has a gasoline engine. The trimmer is lightweight and easy to operate. The rod of the model is bent and with the possibility of disassembly, which facilitates the transportation of equipment. The variety of attachments allows the trimmer to be used as a cultivator, hedge trimmer and lopper. The piston elements of the motor are chrome-plated.

The Trimmer Coil Is Spinning At Idle

The Patriot PT 2540 trimmer functions quite simply. with an increase in the number of revolutions, the spool and line come into rotation. The load on the hands is reduced thanks to the shoulder strap supplied with the equipment. It is convenient for a person of any height to work with the equipment, since all parameters are adjusted. The cutting edge is consumed in a semi-automatic mode, when the spool is pressed against the ground at the moment of rotation, the line comes out of it to the desired length. Surplus is removed with a knife, which is equipped with a protective cover. It is recommended to reduce the load on the engine by developing the maximum number of revolutions during operation.

Operating instructions for petrol trimmer Patriot PT 2540

Precautions and getting started with the trimmer:

  • At the beginning of work, it is necessary to check all the elements of the device, the correctness and reliability of their fastenings.
  • The switched on equipment must not be left unattended. During work, children must be removed to a safe distance.
  • It is necessary to remove from the territory all solid elements that pose a threat to the cutting element of the equipment.
  • Protect eyes, hands and feet when cutting grass with a trimmer with glasses or a mask, gloves and closed shoes.
  • Carefully protect the trimmer from moisture to avoid corrosion.
  • Start the trimmer on a flat and dry surface. For operation, do not use a line more than 2 mm in diameter in order to avoid damage to the apparatus. The line cannot be replaced with reinforced, iron cables and wires.
  • The fuel mixture is prepared from gasoline with an octane rating of at least AI-95 and original oils and greases from Patriot.
  • If during operation a fuel mixture leaks, it is necessary to move away from this point at least 3 meters and only then start the device. Never pour the fuel mixture into the trimmer with the engine running or hot.
  • It is necessary to regularly diagnose the health of the device. If you find the slightest malfunction, stop operation and take the equipment to the service center.
  • It is strictly forbidden to use the trimmer in closed rooms. It is designed for outdoor use only.

Immediately after winding up

The unit may stall immediately after starting if the carburetor is misaligned or incorrectly adjusted. this causes uneven fuel supply. The result of this is that the device vibrates distinctly. For troubleshooting, the carburetor is reconfigured, following the instructions for the mechanism.

Also, the engine stops when the fuel supply valve becomes clogged. In such cases, it is sufficient to simply clean it. If the lawn mower first started working, but then immediately stalled, then the fuel may enter the carburetor unit with some difficulty. Weakening the valve helps to resolve the issue, which ensures free circulation of the mixture in the system.

The stoppage can also be caused by air leaks in the presence of mechanical damage to the hose (holes, cracks) that takes the fuel. In this case, add more revolutions to the drive in order to quickly expel air bubbles from the system.

When you hit the gas

If the lawn mower stops when the throttle is pressed, the reasons may be as follows:.

  • The most common option is carburetor adjustment failure, which occurs when the drive is under heavy load, after prolonged inactivity of the mechanism, or when it is used in difficult conditions.
  • Clogged fuel valve, which is eliminated by loosening it, as a result of which gasoline begins to flow normally through the system.
  • Loosening and drooping of the cable in the carburetor. The fuel hose may also be stretched to the point of rupture due to significant stress.
  • Clogged breather (check valve), as a result of which fuel does not flow into the tank.

If the problem is with the carburettor assembly, the lawn mower vibrates to recognize it. When the hose bursts or the cable is stretched, these components are replaced.

What could have broken

Problems with the lawn mower due to the fact that this device does not start are classified in a certain way by service specialists. They highlight faults with the following components of the mechanism:

  • An engine in which the piston and bearings may wear out or fail, crack the crankcase;
  • The fuel supply system, while the filter may be clogged or problems with the carburetor;
  • Mechanical damage to wires, tubes, hoses;
  • Ignition circuit.

At high revs

When the scythe stalls at high speeds, this is due to the following problems:

  • Clogged or sticking valve located on the gas tank cap;
  • The carburetor is out of alignment under the influence of vibrations arising from the operation of the mechanism;
  • Problems with the circulation of the fuel mixture;
  • Leakage of atmospheric air;
  • The fuel intake hose is cracked or loose.

Adjust the carburetor referring to the trimmer operating instructions. For adjustment, it is often sufficient to loosen the tightening of its housing. If there are problematic moments with the circulation of the fuel mixture, then it can gradually enter the carburetor. After its development, the engine stalls at high speeds.

Why does the petrol trimmer stall

A scythe with a gasoline drive is a useful thing for owners of home gardens, lawns, and when the trimmer suddenly stalls, the work on clearing the area from grass stops. The device itself is a rather complex mechanism, so there are many different reasons for its breakdown. The most common problems are contained in the operating instructions. You should know the reasons why the trimmer stalls in order to effectively repair the device yourself.

When heated

the lawn mower often stops when it heats up. At the same time, it starts, works “jerky” and gradually stops. This process occurs when the gasoline in the carburetor boils or the damper is installed in a rotary rather than disc type. In the latter case, the part is changed.

It happens that the trimmer heats up if the ignition circuit wire or coil is damaged. In order for the device to start working normally, replace parts.

Idle

At idle, common reasons for trim stopping are as follows:

  • Dirty, misaligned or incorrectly adjusted carburetor adjustment;
  • Clogged air filter;

Replacing the air filter for lawn mowers

Trimmer air filter

  • Reducing the speed of the gearbox when it heats up, which is a consequence of using an unsuitable fuel mixture;
  • Clogged throttle;
  • Air ingress into the system;
  • Not enough fuel to operate the lawn mowers.

When the air damper is opened

It happens that the unit stalls when the air damper is opened, working normally at idle speed. This is due to air leaks in the system, caused by cracks in the fuel hose or problems with the oil seals. The carburetor metering system may also malfunction, and the lawn mower will stop after opening the damper.

For all possible causes of the lawnmower stalling and remedies, see the following

There are many reasons for stopping lawn mowers, but the most common malfunctions associated with its carburetor. They can occur in any case. The most problematic option is when a serious breakdown occurs, and you need to purchase new parts or change the lawn mower.

Typical breakdowns of gasoline and electric trimmers

Grass trimmers are an indispensable tool in your home area to quickly remove unwanted weeds. But, like any other technique, they break over time. To repair or adjust garden tools, you need to know its structure, the principle of operation, as well as the nature of typical malfunctions of a trimmer that runs on both gasoline and electricity.

Exhaust system

If the lawn mower stalls when the user clicks on the throttle and revs up the engine, it could indicate a clogged exhaust system. This is due to the large amount of burning generated during the combustion of the oil that is part of the fuel mixture. To fix the problem, you need to clean the muffler and related parts.

Mechanical breakdown

If the motor starts but the cutting unit does not rotate, the malfunction may be due to a broken flexible shaft. This happens in the absence of regular maintenance of the equipment. The problem is relevant for an electric scooter with a motor located on top. To eliminate it, you will need to disassemble the braid and lubricate the shaft.

Trimmers with a bottom motor do not have a flexible shaft, but they can break the main shaft on which the line spool is attached. The reason is the destruction of the bearing. Solving the problem. installing a new part.

Start button

The first part to check if the tool does not turn on is the start button. The problem may be with it or a broken cord inside the device. For diagnostics, it is necessary to disassemble the handle and ring the parts with a multimeter.

Electric group trimmers. battery

There is another type of electric trimmer. cordless. These tools are low-powered and not designed for continuous operation (on average. 15-25 minutes, with a full charge in 3-4 hours).

The advantage of this type of equipment is mobility and low noise level, therefore it is used in areas where noise is not allowed. These are hospitals, hotels, sanatoriums. In addition, the use of these trimmers is important in cases where the electric cable greatly interferes with work and movement. However, before each turning them on, you need to check the battery charge.

Drive shaft and rod

If a strong vibration appears during operation, this indicates the absence or lack of lubrication on the shaft inside the rod. In this case, even the anti-vibration system will not help. shock absorbers placed between the rod and the motor. To fix the problem, it is necessary to disassemble the scythe and lubricate the shaft. And in order to avoid another manifestation of such a breakdown, you need to regularly service the device. If the vibration persists after lubricating the shaft, it must be replaced.

Clutch

If the cutting edge of the trimmer is constantly spinning at idle speed of the engine, and an uncharacteristic metallic grinding is heard, these are signs of a faulty clutch. Usually the cause is a broken or stretched spring. If slip is added to this, then the pads are also faulty.

Reducer

A trimmer-mounted gearbox is used to transfer rotation from the shaft to the cutting head. It includes a housing, bearings and gears. On its part, there may be the following malfunctions.

  • The transfer unit is heating. The reason is the lack or poor quality of the lubricant. It needs to be added or completely replaced. Also, this phenomenon can manifest itself when new gears are installed. In this case, you need to let the tool work under light loads, regularly interrupting work in order to avoid overheating of the equipment.
  • Knocking, backlash, shaft seizure indicate bearing deformation. Replacement required.
  • The transmission wobbles or flies off the bar. This means the case is damaged. It is necessary to replace the rod or tighten it with a metal clamp if the damage is minimal.
  • The gearbox is not attached to the shaft. This is typical for a worn out joint. You can change the rod or wind up the electrical tape.
  • The knife does not rotate or stops when loaded. This means that the gears are worn out (in whole or in part). Parts need to be replaced.

Starter

The purpose of the starter is to help lawn mowers start the engine. The main malfunctions of this unit are: a break in the cord and a breakage or release from the hook of the spring. To eliminate the malfunction, the starter is disassembled, the cord is changed to a new one, and the spring is returned to its place, or, if it is damaged, another one is installed.

Diagnostic features

A well-posed question is already half the answer. The search for a solution will be significantly accelerated by the fact. under what circumstances a gasoline trimmer or lawn mower stalls, namely:

  • Immediately after the start;
  • When it has been idling for some time. after one or several minutes;
  • When you press the gas button (or knob). or soon after starting work at high, near-maximum speeds;
  • Under heavy load (for example, to prune bushes, mow dense and tall weeds);
  • When warmed up in the cold, it heats up unnecessarily (the lawn mower has stalled due to overheating);
  • After opening the air damper.

When you hit the gas

If the lawn mower stops when the throttle is pressed, the reasons may be as follows:.

  • The most common option is carburetor adjustment failure, which occurs when the drive is under heavy load, after prolonged inactivity of the mechanism, or when it is used in difficult conditions.
  • Clogged fuel valve, which is eliminated by loosening it, as a result of which gasoline begins to flow normally through the system.
  • Loosening and drooping of the cable in the carburetor. The fuel hose may also be stretched to the point of rupture due to significant stress.
  • Clogged breather (check valve), as a result of which fuel does not flow into the tank.

If the problem is with the carburettor assembly, the lawn mower vibrates to recognize it. When the hose bursts or the cable is stretched, these components are replaced.

During engine warming up

If the engine heats up too quickly, overheats. the lawn mower or trimmer works unevenly, as if in jerks. Then it stalls. The reason may be as follows:

  • Boiling gasoline;
  • The ignition wire is damaged (poor insulation);
  • The coil in the ignition system has noticeably burned out, inter-turn short circuits have appeared.

The same heating is observed when using a rotary (rather than disc) damper.

When the air damper is opened

The mower or trimmer stalls when the shutter is raised for the following reasons:

  • Pumping excess air due to a cracked fuel suction hose;
  • Oil seals are worn out;
  • Incorrect operation of the fuel and air metering unit when mixed.

Stop the lawn mowers in this case immediately.

Idle

At idle, common reasons for trim stopping are as follows:

  • Dirty, misaligned or incorrectly adjusted carburetor adjustment;
  • Clogged air filter;

Replacing the air filter for lawn mowers

Trimmer air filter

  • Reducing the speed of the gearbox when it heats up, which is a consequence of using an unsuitable fuel mixture;
  • Clogged throttle;
  • Air ingress into the system;
  • Not enough fuel to operate the lawn mowers.

Immediately after the start

The stalling of the lawn mower or trimmer immediately after the start is due to the following reasons:

  • Imbalance of previously adjusted valves;
  • Initially incorrect valve train setting;
  • Clogging of the fuel supply valve by deposits;
  • The hose is worn out or loosely connected.

Due to a broken fuel injection algorithm, the lawn mower or trimmer vibrates strongly during operation.

With increasing speed

If the lawn mower (or trimmer) stalls when adding engine speed. check the device for the following symptoms:

  • Blockage or sticking of the valve built into the gas tank cap;
  • Violation of valve adjustment;
  • Failure in the operation of pistons and cylinders. from vibration during the operation of the scythe or trimmer, accidental blows directly during the mowing session;
  • Violation of the supply of the air-fuel mixture;
  • Excessive pumping of air into the motor;
  • Cracking of the fuel inlet hose, loosening of its connections.

When the air-fuel mixture is supplied in the required portions to the engine out of time, it burns the amount that has managed to come in since the last stalling, and itself stalls again.

At high revs

When the scythe stalls at high speeds, this is due to the following problems:

  • Clogged or sticking valve located on the gas tank cap;
  • The carburetor is out of alignment under the influence of vibrations arising from the operation of the mechanism;
  • Problems with the circulation of the fuel mixture;
  • Leakage of atmospheric air;
  • The fuel intake hose is cracked or loose.

Adjust the carburetor referring to the trimmer operating instructions. For adjustment, it is often sufficient to loosen the tightening of its housing. If there are problematic moments with the circulation of the fuel mixture, then it can gradually enter the carburetor. After its development, the engine stalls at high speeds.

Immediately after winding up

The unit may stall immediately after starting if the carburetor is misaligned or incorrectly adjusted. this causes uneven fuel supply. The result of this is that the device vibrates distinctly. For troubleshooting, the carburetor is reconfigured, following the instructions for the mechanism.

Also, the engine stops when the fuel supply valve becomes clogged. In such cases, it is sufficient to simply clean it. If the lawn mower first started working, but then immediately stalled, then the fuel may enter the carburetor unit with some difficulty. Weakening the valve helps to resolve the issue, which ensures free circulation of the mixture in the system.
