How to repair the starter spring on a generator and chainsaw. How to repair a chainsaw starter with your own hands Replacing a chainsaw starter spring easy start

On almost all launchers modern type It is recommended to install a spring to start the generator in case of battery failure. Over time, the device may fail, and then you need to know how to repair the starter spring on the generator yourself.

Why do you need a manual starter?

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline!

An electric starter is provided as the main starter. However, do not forget that if the battery is faulty, starting the vehicle using an electric starter will not work. It was intended for this case manual option, as a backup option.

A striking example of the use of a manual starter is portable power plants. It is easier to use a manual starter on them, because it makes it possible to conveniently start the engine and operate the generator.

Recoil starter spring fault

The tight starter spring with hook is the main design element of the manual starter. In addition to the spring, the starter also includes the following components:

• Ratchet;
• Cord with reel;
• Screw for fixation;
• Return spring;
• Plastic ratchet fuselage.

Repairing a spring, the main component of a manual starter, comes down to replacing the element.

Here's how the replacement is done:

• Use a screwdriver to unscrew the pulley screw;
• Then the spring itself is removed.

On chainsaws, for example, it is an element in the form of a circle, inside of which a flexible spring is wound.

Springs are sold in this form in hardware stores. All that remains is to buy the part and replace it.

Repairing a recoil starter may also involve replacing the cord. If it is incorrectly wound on the spring pulley, the generator will not start.

Here are some rules for winding cord:

• Wind the cord from the end of the pulley (this is done to avoid twisting);
• The second end of the cord is inserted into the hole in the lid;
• Winding the cord should continue until it stops, that is, as long as the length of the rope is sufficient;
• After winding, the cord is pulled out 15-20 cm to check the rotation of the spring pulley;
• After winding, you should also check how the spring works after pulling and releasing (if everything works well, it is recommended to wind the cord one more turn).

On portable power stations, spring and cord repairs are carried out as follows:

• On the side of the generator there is a pulley circle, fixed with three screws that must be unscrewed;
• Remove the pulley with the spring and the cord;
• Check the condition of the cord, which can be completely removed from the side of the holder (the upper cap of the holder is removable).

Note. Often the knot of the cord that secures it from above becomes loose. To correct the situation, you need to heat the end of the nylon rope with a lighter, and then wind a new knot.

As for the pulley with the spring, it is changed in the same way as described above.

Operating rules

According to experts, there is a high probability of damaging the spring if it is not correct operation. It takes a lot to know how to operate a manual starter correctly.

Chainsaw is an indispensable tool not only for the summer resident, but also when carrying out construction work. If you need to stock up on firewood for the winter, then going into the forest without a chainsaw makes no sense at all. If the tool is used correctly, it can last for a long time, but in any case, sooner or later there will be various types malfunctions. One of these malfunctions is a breakdown of the starter, which makes it difficult to start the engine. In this situation, it is advisable to repair the chainsaw starter yourself. We will find out how to do this in the material.

All types of chainsaws, both Chinese and European, are equipped with starters of identical design and operating principle. Universal design starters allows the use of these devices both on branded chainsaws and on semi-official tools supplied from the Middle Kingdom. It is only important to note that some distinctive features have domestically produced instruments.

A starter for a chainsaw is a simple mechanism consisting of:

• Drum.
• Rope.
• A handle connected to a cable.
• Frame with return spring.

The operating principle of such a device is also quite simple. When the handle, which is connected via a cable to the drum of the ratcheting mechanism, is pulled, it moves. When moving, the drum engages with the splines of another drum, which is located on the shaft. Thus, the crankshaft of the saw moves manually, which makes several revolutions. As soon as the handle returns to its original position, assisted by the return spring, the spline connection is lost, causing the shaft to stop. With each movement of the crankshaft, the amount of fuel-air mixture in the cylinder increases, which ultimately contributes to its ignition.

The greater the power of the tool, the more jerks the starter must make to start the engine. The return spring, which is manufactured using steel with a high degree of elasticity, is responsible for accelerating the return of the drum to its original position.

Over time with constant operation tool, there are problems with starting the engine, or more precisely, with the functioning of the starter. If such problems arise, the starter can always be repaired. If you know the principle and design of the starter, then repairing it yourself will not be difficult at all.

Typical breakdowns and repairs of a chainsaw starter

Before carrying out repairs, it is necessary to find out the causes of the breakdown. Since the product is constantly exposed to dynamic and other types of loads, its failure cannot be ruled out. Frequent causes of starter breakdowns are: cable rupture, abrasion or chipping of several splines of the ratchet drum, spring damage, pulley crack, and others. To determine why the saw does not start, you will need to carry out an appropriate inspection of the starter mechanism. Let's look at the main types of faults, and also find out how to properly repair the product.

Replacing the cord

The starter cord is a strong rope that is quite resistant to wear and tear, but even it technical properties do not save it from damage. Each time the tool is started, the rope rubs against the body of the starter cover, which leads to its gradual chafing and wear.

If the cord is frayed, then to replace it you will need to disassemble the housing of this unit. After removing the cover, it is necessary to lift the drum, but only in such a way that it does not jump out of its seats. It is recommended to carry out this work together with a partner who will fix the spring, and you will replace the cable. The remains of the old cable should be removed, and then the new product should be secured in the handle and in the groove of the drum. After this, the cable should be wound onto the roller, and finally assemble the housing.

Important to know! Before fixing the cable in the handle, you should pass it through the corresponding hole in the starter cover.

How to replace a chainsaw starter spring

If the spring is damaged, which often happens on Chinese instruments, then the mechanism can only be repaired by replacing it. But if its damage occurred at the attachment point, that is, the ear burst, then it can be repaired.

Repairing a spring involves heating the fracture site to 600 degrees, then slowly cooling it to 100 degrees, at which point the end is folded into the shape of the fragment. Thus, it will be possible to avoid loss of elasticity of the product, which will extend its service life. Although most specialists simply replace the product with a new one.

The spring replacement process is carried out in the following sequence:

1. Initially, the cage or drum of the mechanism is removed.
2. There is a spring inside the drum. To dismantle it you will need to fix it top part, then pull the starter handle to the side.
3. When the old spring is removed, you will need to install a new one. In this case, it is necessary to clean the housing.
4. When installing a new spring, insert it into the starter, and then get the tendril into the groove.
5. When the work is completed, you can put on the drum and replace the starter cover.

The detailed process of replacing the spring is discussed in the video:

Replacing flywheel pawls

If it is necessary to replace the pawls or flywheel links, then this is also not difficult to do. To do this, you will need to dismantle the flywheel and then remove the pawls. New pawls should only be installed as they were originally (plastic or metal). This is very important, since replacing plastic pawls with metal ones will lead to accelerated wear of the flywheel. Details of replacing the chainsaw starter dogs are discussed in the video below.

In conclusion, it is important to note that you do not need to have any special skills or experience to repair a chainsaw starter. All work can be done independently if you treat the repair process with full responsibility. Timely maintenance of the chainsaw will allow you to avoid breakdowns when performing work in the field.

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;

The chainsaw is extremely important tool for owners of private houses and summer cottages. Using it, you can tidy up the garden, cut down dried trees and stock up on firewood for the fireplace, bathhouse, and heating the house. If you use the saw for its intended purpose, following the operating instructions, it will last a long time. Over time, the mechanisms may wear out and cannot be repaired. In this article you can find a description of how to repair a starter for a chainsaw.

Components

As can be seen in the photo, the starter consists of the following elements:

• Screws;
• Sleeve;
• Starting spring;
• Coil;
• Deflector;
• Lid;
• Handle, cord.

The most common injuries

Most often you can encounter the following malfunctions:

• Failure of the ignition system;
• Sudden stop of the saw;
• Power reduction;
• Wear and tear of chainsaw systems and mechanisms;
• Problems with the fuel supply system;
• Faulty starter.

To avoid malfunctions, it is necessary to check the condition of the saw every time before starting work. The fuel level, oil availability, and chain lubrication should be monitored. It is easier to prevent problems through timely preventive inspection than to fix them later.

The malfunction of each system is eliminated different methods. Some breakdowns can be fixed with your own hands. For example, if there is a problem with the fuel supply system, you should first check the filter. Then you need to see if the carburetor is adjusted correctly. All gaps must be adjusted in full accordance with the instructions that come with the saw. You should also check the condition of the spark plugs. If there is visible damage, a large layer of carbon deposits, displacement and other changes, it is necessary to replace damaged and faulty elements.

Repair

If there is a problem with the starter, the chainsaw will not be able to start working after the cord is pulled. The tool will not start. The main reasons for saw failure may be:

• Pulley cracks or breakage;
• Spring damage;
• Trigger cable break.

To carry out inspection and repair, the following tools and parts are required:

• Necessary screwdrivers, or a handle with interchangeable attachments that are suitable for this work;
• Replacement elements to replace faulty ones if necessary (for example, a replacement cord).

To inspect and repair the starter, you first need to remove it from the housing. This can be done by using a screwdriver or other special tool to unscrew the screws that hold the side cover with the starter. Next you need to remove the cover and inspect the mechanism. The screw that attaches the mechanism to the cover of the chainsaw should be unscrewed, and then the clamp and the trigger spring should be removed. This will provide access to the pulley with the wound cord. If the cord is damaged, it must be replaced with a new one. If the failure involved a broken cord, these actions will bring the saw back into working order. All other elements of the mechanism should be carefully inspected for damage.

Sometimes upon examination you may notice other damage, namely:

• Pulley damage. This includes splits, tears and other damage that prevent the instrument from working properly;
• Chainsaw starting spring malfunction. This includes problems with the spring and defects in the mounting location. The place where the spring is inserted into the fastener is considered the most problematic part of the fastener.

If faults or weaknesses are found during inspection, it is necessary to replace damaged parts. You need to make sure that the parts match the saw model, otherwise you may end up with an even bigger problem.

Having completed the repair and replacement of parts with your own hands, you need to assemble the mechanism correctly, in the reverse order. The pulley must be installed on top of the trigger spring and be firmly engaged with it. The pulley is wrapped with a cord threaded through a hole in the cover so that when it starts and rotates, it pulls the cord into the mechanism. To obtain the required cord voltage, you should make 4 turns - this is enough. You can get acquainted with the starter repair technology by watching the video.

To fix problems yourself, you may need additional steps. For example, if you cannot match the openings for the cord in the pulley and the housing cover the first time, you should make several additional turns.

After the mechanism has been repaired and installed in place, the launch can begin. All renovation work does not have to be done at home. If you don’t have enough experience and free time, you can contact the service center.

Timely preventative maintenance will help avoid sudden breakdowns. If you approach working with a chainsaw responsibly, keep an eye on it technical condition, monitoring the quality of the fuel can extend the life of the tool.
