Husqvarna Chainsaw Starter Spring Replacement

A chainsaw is the main tool with which you can stock up firewood for a bath or fireplace, and you can also use it for construction work on a summer cottage or in a private house. Subject to all operating conditions and the implementation of preventive measures that are provided by the manufacturer, the chainsaw can last a long time. But after a lapse of time, minor malfunctions can occur that can be dealt with on your own. For example, repairing a starter for a chainsaw with your own hands is quite capable of observing the sequence of operations.

Chainsaw starter device: 1. starter screw, 2. bushing, 3. easy-start spring, 4. screw, 5, 6. starter coil, 7. baffle, 8. starter cover, 9. handle and cord, 10. screw.

Typical malfunctions

The most common tool breakdowns include the following:

  • problems in the ignition system;
  • stopping the operation of the chainsaw in the process of cutting;
  • 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 associated with the starter.

In addition, it is necessary to carry out a visual inspection of the chainsaw before starting work and preventive measures. These include chain lubrication, control of the amount of fuel mixture, as well as the presence of the required amount of oil.

Unscrew the spark plug to check its condition.

Each of the faults is eliminated by its technology. So, for example, repair of the fuel system of a chainsaw should begin with an inspection of the appropriate filter. After that, check the carburetor regulation, which is carried out using 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 of candles. If a strong deposit is detected, a change in the gap or other visible damage occurs, this element must be replaced.

Starter repair work

Problems in the operation of the starter may not ensure the launch of the tool. That is, after the cord is pulled, the chainsaw does not start to work.

The causes of the malfunction are:

  • broken or cracked pulley;
  • bursting spring;
  • rush trigger cable.

Before repairing the starter, it is necessary to prepare the tools with which to perform work:

  • a set of screwdrivers or a special tool that is supplied with the tool by the manufacturer;
  • rope, which will be used as a replacement for a torn cord if necessary.

A large amount of black soot on the spark plug indicates a malfunction in the engine.

Before proceeding directly with the repair of the starter and finding out the causes of malfunctions, it must be removed from the tool body. To do this, 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 cover is unscrewed, it is turned over and inspected. Next, unscrew the screw with which the starter is fixed. After that, the clamp and spring are dismantled for a smooth start. Now the pulley on which the cord is wound is available for removal. After the knot on the rope is untied, it can be pulled out from the pulley and replaced with a new one. Provided that the starter’s loss of functionality is connected with a break, this may be sufficient to eliminate the breakdown. However, the remaining parts that make up this element of the chainsaw should be carefully inspected.

When examining the components of the starter, the following malfunctions can be identified:

Most often, a soft start spring is damaged from the end where it is visible when the housing is disassembled.

  1. The pulley may be damaged. Cracks or tears are possible, as well as damage to the rear. As a result of these problems, the tool cannot do the work.
  2. Damage to the soft start spring. In this case, the spring itself may be mechanically faulty, and 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 defective or partially damaged starter parts are found, they must be replaced with new ones. In this case, the new elements must correspond to the model of the saw being repaired.

After the repair is completed, the starter must be assembled correctly.

The pulley is mounted on top of the spring. In this case, it is necessary to check how much they interlocked with each other. To continue the repair, the pulley must be wrapped. This must be done so that during rotation, he pulls the cord into the starter. It is enough to make 3-4 turns to give the required voltage. Previously, the rope is passed through the hole in the lid of the chainsaw.

Practical recommendations

In order to match the holes for fixing the cord in the pulley and housing, you may need to make a few more turns. A new rope is threaded into 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, fix the pulley.

First you need to replace the soft start spring. It can be used the same if no damage is found in it. or new if replacement is necessary. On top of the spring set the starter clamp, which is fixed with a special screw. It reliably fixes the clamp for a long time, preventing it from skewing and swaying. After this, you need to make several turns of the rope and run it inward. The cover with the assembled starter is installed in place. Using screws, it is secured.

After the repair and assembly, you can begin to work. Self-repair of the starter does not take much time and does not require complex skills, but it saves time and money if you perform such work in the service center.

Chainsaw repair should be approached responsibly and promptly to carry out preventive examinations, monitor the quality of the fuel and oil used. These simple manipulations will increase the duration of the tool in working condition.
