Starter spring repair. How to repair a chainsaw starter. Why do you need a manual starter?

If difficulties arise when starting the tool, power is lost, or malfunctions occur in the fuel supply system, then you need to repair the chainsaw starter yourself or send the tool to a service center.

Device

The chainsaw starter device includes the following elements:

ignition system screw;
return spring;
starting system coil;
deflector;
lid;
magneto;
drum;
spark plug;
the electronic unit;
wiring;
power button;
handle and cable.

Main parameters of the chainsaw starting system:

power - from 2000 to 2500 W;
maximum number of revolutions per minute - 3000;
weight - 0.5 kg.

After pressing the power button, the flywheel begins to rotate along with the magnet that is located on it.

An electromotive force appears in the system. The resulting current is converted into electrical signals using an electronic unit, which are transmitted to the moving elements. A spark is formed, which provokes ignition of the fuel-air mixture.

How to repair a starter on a chainsaw

The cause of a malfunction of the chainsaw starting system may be:

Drive pulley. This part is subject to high axial and radial loads, so before starting work it is recommended to inspect the pulley for damage and cracks on the back of the housing. If necessary, repair the part or replace it with a new one.
Spring mechanism. If it has lost its properties or has cracks or breaks, this element must be replaced. It is also recommended to inspect the mounting points for defects.
Launch system rope. The rope should be inspected for wear and damage. If necessary, replace the part and install it on the pulley.

Diagnostics

Diagnostics of the tool launch system is carried out as follows:

Unscrew the mounting screws and remove the cover.
Unscrew the screw that secures the mechanism to the protective cover.
Start the starter smoothly by removing the spring and clamps from it.
To inspect for wear and defects, dismantle the cable reel.
Check the fuel system for the presence of water in it. If there is water inside the system, the fuel fluid must be replaced.
Inspect the power unit for overfilling with fuel fluid. In this case, you need to unscrew and dry the spark plug, pull the starter, removing the air damper.
Check the spark plug for a spark.

Replacing the cord

In order to replace the cord, you will need the following tools:

Screwdriver Set;
rope.

Replacing the starter cord is done as follows:

You need to unscrew the mounting screws that hold the side cover in place using a screwdriver.
Then remove the starter from the tool body.
After this, you need to turn the lid and inspect it.
Then remove the clamp and spring.
You should untie the knot on the rope.

The design and principle of operation of a chainsaw starter

Majority famous manufacturers chainsaws equip their products with starters that work on almost the same principle. Its essence is as follows: in the groove of the saw body there is a handle through which the cord is passed. When the handle is raised sharply, the cord is also pulled out, which engages the drum, which is located in the ratchet mechanism. Through this, a drum with spokes, which is located on the shaft, is activated. During this, the crankshaft makes a couple of revolutions, which leads to compression fuel mixture, which at this moment is located between the cylinder head and the piston. When the handle is lowered, on the contrary, the ratchet and the pins lose their contact, which leads to the shaft stopping.

As the power of the chainsaw increases, the amount of fuel mixture increases, which must ignite when the chainsaw is started. In this case, to start the engine, it is necessary to increase the number of pulls on the starter cord. To speed up the return of the drum mechanism, manufacturers use a special steel starter return spring, which has excellent elasticity. To make starting a chainsaw easier, leading brands also use other methods:

Preliminary enrichment of the fuel mixture using a separate damper;
Installation automatic valve decompression, which reduces the pressure inside the chainsaw cylinder;
Installing a primer designed to pump fuel before starting the engine.

The use of one of these technologies significantly facilitates starting and extends the service life of the starter, which is especially noticeable at low temperatures.
