The chainsaw is the main tool with which you can stock up on wood for a bath or fireplace, and you can also use it during construction work on the summer cottage or in a private house. If all operating conditions are observed and preventive measures are taken, which are foreseen by the manufacturer, a chainsaw can last for a long time. But after a time, minor faults can occur that can be handled by yourself. For example, repairing a starter chainsaw with your own hands is quite capable of observing the sequence of operations.
The device of the chainsaw starter: 1- starter screw, 2 - bushing, 3 - easy start spring, 4 - screw, 5, 6 - starter coil, 7 - deflector, 8 - starter cover, 9 - handle and cord, 10 - screw.
The most common tool breakdowns include the following:
- problems in the ignition system;
- stop the chainsaw in the process of performing the cut;
- power loss during operation;
- wear of some structural elements of the chainsaw (brake band, drive sprockets, anti-vibration parts);
- problems in the fuel supply system;
- malfunctions related to the starter.
In addition, it is necessary to make a visual inspection of the chainsaw before starting work and preventive measures. These include chain lubrication, control of the amount of the fuel mixture, and the presence of the required amount of oil.
The spark plug is twisted to check its condition.
Each of the faults is eliminated by its technology. For example, repair the fuel system of a chainsaw should begin with an inspection of the appropriate filter. After that, check the correctness of the regulation of the carburetor, which is carried out with screws. Clearances must be set in strict accordance with the manufacturer’s instructions, which must be included with the chainsaw. To repair the ignition system include inspections candles. If a strong deposit is detected, the gap is changed or other visible damage is present, this element should be replaced.Back to table of contents
Problems in the starter may not ensure the launch tool. That is, after the cord is taut, the chainsaw does not start working.
Causes of failure is:
- pulley breakage or crack;
- broken spring;
- rush trigger cable.
Before repairing a starter, it is necessary to prepare the tools with which to perform work:
- a set of screwdrivers or a special tool that is attached by the manufacturer with the tool;
- a rope that will be used as a replacement for the broken cord if necessary.
A large amount of black carbon on the spark plug indicates violations in the engine.
Before proceeding directly to repairing the starter and determining the causes of faults, it is necessary to remove it from the tool body. To do this, you need to unscrew several screws holding the side cover to which the starter is attached. This is done with a screwdriver or a specialized tool.
After the cap is unscrewed, it is turned over and inspected. Next, unscrew the screw with which the starter is fixed. After that, remove the clamp and spring for a smooth start. Now for removal is available pulley, which is wound on the cord. After the knot on the rope has been untied, it can be pulled out of the pulley and replaced with a new one. Provided that the loss of performance of the starter is associated with a cliff, this may be enough to correct the failure. However, the remaining parts that make up this element of the chainsaw should be carefully examined.
When inspecting the starter components, the following malfunctions can be identified:
Most often, a soft start spring is damaged from the end where it is visible when disassembling the case.
- Pulley may be damaged. There may be cracks or tears, as well as damage to the back. As a result of these problems, the tool cannot perform work.
- Damage to the soft start spring. In this case, the spring itself may be mechanically defective, or there may be defects in the place of its attachment. The weakest point of this element is precisely the mounting location and the tip of the spring, which is inserted into it.
If faulty or partially damaged starter parts are found, they must be replaced with new ones. At the same time, new elements should correspond to the model being repaired.
After the repair is completed, the starter must be properly assembled.
The pulley is installed on top of the spring. At the same time, it is necessary to check how much they have linked to each other. In continuation of the repair, it is necessary to wind the pulley. This must be done in such a way that, while rotating, he pulls the cord into the starter. It is enough to make 3-4 turns to give the required voltage. Pre rope pass through the hole in the lid of the chainsaw.Back to table of contents
In order to match the holes for fixing the cord in the pulley and body, you may have to make a few more turns. A new rope is passed through the technological hole and a loop or knot is made: this will allow it to slip out of the pulley. The rope is set aside so that it does not interfere with further work. Next, you need to fix the pulley.
First, you need to reinstall the soft start spring. It can be used as before if no damage is found in it. or new if necessary replacement. On top of the spring set starter clip, which is fixed with a special screw. It securely holds the clip for a long time, preventing it from tilting and swinging. After that, you need to make a few turns of the rope and run it inside. The lid with the assembled starter is put in place. Using screws make its fastening.
After the repair and assembly, you can get to work. Independent repair of a starter does not take much time and does not require complicated skills, however it saves time and money if you carry out such work in a service center.
It is necessary to approach the repair of the chainsaw responsibly and in a timely manner to carry out routine inspections, monitor the quality of the fuel and oil used. These simple manipulations will increase the duration of the tool in working condition.
