Starter of a chainsaw: DIY repair

An indispensable tool for sawing firewood and rolling of trees is a chainsaw. Following the recommendations of the manufacturer and the implementation of the necessary preventive measures will ensure a long “life” of the unit. But even at the most reliable mechanism over time, problems arise, most of which can be eliminated with your own hands without the help of specialized centers. One of these malfunctions can be a chainsaw starter, the repair of which can be carried out independently, subject to a certain sequence of operations.

Almost all leading manufacturers of chainsaws complete their products with starters of a similar principle of action. It is no coincidence that specialized stores offer universal designs of starters that are equally successful for both Stihl, Husqvarna, Makita chainsaws, and for Chinese semi.official fakes under the named brands. Only starters of domestic production (forester, Urals and a number of others) have some features only.

The principle of operation of the starter for the chainsaw is as follows. A handle is installed in the groove of the case, through which the cable is missed. If the handle is sharply lifted, the cable is stretched, and introduces the drum of a ratchet that transfers the movement to the drum with the slots provided for the shaft. In this case, the crankshaft makes several revolutions, and the working mixture in the space between the piston and the cylinder head is compressed. Accordingly, when lowering the handle, the contact between the ratchet and the slots is lost, and the shaft stops.

With an increase in the volume of the engine, the required amount of fuel-air mixture required for its subsequent ignition is also growing, so the number of jerks for the starting cable for large power saws increases. Therefore, in order to accelerate the return of the drum, baked return springs made of steels with high elastic properties are used.

The relief of the launch of the chainsaw is realized in the following ways:

  • Preliminary enrichment of the working mixture, for which there is a special damper in the design of the carburetor.
  • By installing an automatic decompression valve, which provides a decrease in the working pressure in the chainsaw cylinder.
  • By installing an additional spring, which during the movement of the cable facilitates the spinning of the crankshaft.
  • The presence in the design of some chainsaws (for example, Partner S, Maxcut, etc.) the primer. the pump that provides preliminary pumping of the fuel.

Typical malfunctions

The most common tools of the tool include the following:

  • problems in the ignition system;
  • stopping the chainsaw in the process of performing the sawing;
  • loss of power during operation;
  • wear of some structural elements of the chainsaw (brake tape, leading stars, anti.vibration parts);
  • problems in the fuel supply system;
  • malfunctions associated with the starter.

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

The spark plug is unscrewed to check its condition.

Each of the malfunctions is eliminated according to its technology. So, for example, the repair of the fuel system of the chainsaw should begin with the inspection of the corresponding filter. After that, check the correctness of the regulation of the carburetor, which is carried out using screws. The gaps should be exhibited in strict accordance with the manufacturer’s instructions, which should be attached to the kit with a chainsaw. The repair of the spark plugs includes the repair of the ignition system.

If a severe carrier is detected, a change in the clearance or other visible damage, this element should be replaced.

Repair of the starter of the chainsaw

With frequent launches of the chainsaws, some starter details are constantly subjected to dynamic loads. As a result, a cable may burst, several teeth of the ratchet chill, and the shaft will turn out at a much lower speed. Therefore, the audit and even the repair of the starter. operations, sometimes carried out several times per season.

Replacement of the cord

When it is pulled, there is a constant friction of the cable about the starter case. For replacement, disassemble the hull of the node, and carefully lift the rattles in such a way as not to allow jumping from their nests of the return spring. It is better to do such work together: the assistant fixes the spring, while the cable is replaced. After fixing the cable in the handle and in the grooves of the drum, the cable is wound on the roller, and the case is assembled.

In the design of the chainsaw, the starter is responsible for the working tool starting the engine. Over time, the owners of the chainsaw are faced with the need to repair this important unit. And, the sooner the malfunction can be eliminated, the less other important details and tool mechanisms succumb to wear.

Repair of the starter of the chainsaw

Chainsaw is an indispensable tool for the construction and harvesting of firewood. Proper operation with moderate work provides a long life of the tool without breakdowns. However, troubles can arise completely unexpectedly and the serviceable chainsaw is losing performance, and the malfunction can be completely trifling.

The repair of the starter of the chainsaw is presented after a breakthrough of the launch cord. Without a starting cord, a chainsaw becomes completely non.working, there is no other way to start the tool. Repair is shifted on the example of the Partner P350S chainsaw, a cunning reliable launch of this saw requires at least 4-5 times to pull the launch cord so that the saw earns, therefore, probably, the first fault was in the cord cliff. The cord does not break right away, first the protective stocking of the string of the cord threads breaks and interferes with the launch of the saw. It is better not to wait for a cliff of all threads and fix the cord in advance. It is not necessary to invent anything, the repair should not cause difficulties, but accurate compliance with the assembly conditions is required. Step by step instructions with a scheme of actions with photos and videos are given below.

The procedure for the repair

First we unscrew the screws of fastening the starter cover (usually 3 or 4). When buying a chainsaw, a candle key with a simple screwdriver is attached to it. If there is no branded box at hand, you can use ordinary tools. Next, remove the starter from the chainsaw body. As a rule, there are no problems with this even with sufficient dusting and clogging of the tool.

Then you should unscrew the screw of the supply mechanism of the smooth start and coil. In this case, you need not to lose the puck that is necessary for the design. Immediately after we extract a smooth start mechanism and a winding reel on which traces of damage may be present (for example, fasteners).

Then we fix the coil with your hand, pull the loop by the handle out. Holding the cord and the mechanism with the hand, we ensure the winding of the cable to the reel.

Check the serviceability of the starter mechanism after replacing the cable and fix the node to the chainsaw housing with fasteners.

If repairs using a linen rope are not an option, managers of the PPD Tool store will select a branded starter cord from an extensive assortment of spare parts for chainsaws.

Tips from professionals

For an accurate orientation of holes in the housing and channel fixation of the rope, it may be necessary to make 2-3 turns.

In order to exclude slipping out the cord from the pulley, it is necessary to tie a knot, in diameter exceeding the hole in the housing. In the absence of wear (damage) the spring, it is installed first when assembling the starter of the chainsaw. On top of it, a pulley and a starter clamp are mounted, which does not allow a skew of the mechanism during rotation.

Device and principle of operation of the starter of the chainsaw

All types of chainsaws, both Chinese and European production, are equipped with starters of the identical design and the principle of action. The universal design of the starters allows you to use these devices on both brand chainsaws and on semi.official tools supplied from the Celestial Empire. It is only important to note that some distinguishing features are have instruments of domestic production.

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

The principle of operation of such a device is also quite simple. When stretching the handle, which is connected by means of a cable with the drum of the ratchet, its movement occurs. The drum when moving is included in the hook with slots of another drum, which is located on the shaft. Thus, manually moves the cut of the saw, which makes several revolutions. As soon as the handle returns to its original position, which is facilitated by the return spring, the slotted connection is lost, which leads to the stop of the shaft. With each movement of the crankshaft in the cylinder, the amount of fuel-air mixture increases, which ultimately contributes to its ignition.

The greater the power of the tool, the more jerks should be made by the starter to start the motor. The return spring is responsible for accelerating the return of the drum to its original position, the manufacture of which is carried out using steel with a high degree of elasticity.

Over time, with the constant operation of the tool, problems are observed with the launch of the engine, or rather, with the functioning of the starter. If such problems arise, then the starter can always be repaired. If the principle and device of the starter is known, then it will not be difficult to repair it with your own hands.

Typical breakdowns and repair of the chainsaw starter

Before carrying out repairs, it is necessary to find out the reasons for the breakdown. Since the product is constantly subjected to dynamic and other types of loads, its failure is not excluded. Frequent causes of starter breakdowns are: rupture of the cable, abrasion or painting several shits of the rattle drum, damage to the spring, a crack of the pulley and others. To determine why the saw does not start, you will need to conduct an appropriate revision of the starting mechanism. Consider the main types of malfunctions, and also find out how to properly repair the product.

Replacement of the cord

The starter cord is a strong rope, which is strong enough to wear, but even its technical properties do not save it from damage. The rope, at each start of the tool, rubs against the starter cover case, which leads to gradual overwhelming and wear.

If the cord is grinding, then to replace it, you need to disassemble the case of this node. After removing the cover, it is necessary to raise the drum, but only so that it does not jump out of his seats. It is recommended to carry out such work together with a partner who will fix the spring, and you will do the replacement of the cable. The remnants of the old cable should be removed, then fixed the new product in the handle and in the frame of the drum. After that, the cable should be wound on the roller, and at the end, assemble the case.

It is 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 the chainsaw starter spring

If damage to the spring is observed, which is often on Chinese instruments, then the mechanism can only be repaired by replacing it. But if its damage occurred at the place of connection, that is, the ear burst, then it can be repaired.

The repair of the spring is a heating of the destruction site up to 600 degrees, after which it is slow to cool it up to 100 degrees, in which the end is wrapped in the shape of a fragment. Thus, it will be possible to avoid loss of elasticity of the product, which will extend its service life. Although most experts simply carry out the replacement of the product with a new.

The process of replacing the spring is carried out in the following sequence:

  • The clip or drum of the mechanism is originally extracted.
  • A spring is located inside the drum. To dismantle it, you will need to fix its upper part, and then pull the starter handle aside.
  • When the old spring is extracted, you need to install a new. In this case, it is imperative to clean the body.
  • When installing a new spring, you should insert it into the starter, and then get into the groove to the groove.
  • At the end of the work, you can put on the drum and install the starter cover in place.

Replacing dogs of a flywheel

If you need to replace the dogs or the answer of the flywheel, then it is also not difficult to do it. This will need to dismantle the flywheel, and then remove the dogs. You should install new dogs exclusively those that were initially (plastic or metal). This is very important, since replacing plastic dogs with metal ones will lead to an accelerated wear of the flywheel. Details of replacing dogs of the starter of the chainsaw are considered in the video below.

It is important to note that to repair the starter of the chainsaw, you do not need to have special skills or experience. All work can be performed independently if you treat the repair process with all responsibility. Timely conduct of the prophylactic work of the chainsaws will avoid the occurrence of breakdowns when performing work in the field.

Starter is one of the most important mechanisms in the device of any modern chainsaw. The launch of the tool engine under any weather conditions depends on it. The starter for the chainsaw is released by a simple design, it is easy to serve and repair it with your own hands. However, in order to eliminate the breakdown, you must first find its cause. For this, most often it is necessary to completely disassemble the standard mechanism.

How to fix a starter on a chainsaw

The reason for the malfunction of the launch system of the chainsaw may be:

  • Drive pulley. This part is subjected to high axial and radial loads, therefore, before starting work, it is recommended to inspect the pulley for damage and cracks on the back of the case. If necessary, repair the part or replace it with a new.
  • Spring mechanism. If he has lost his properties or there are cracks or breakthroughs on it, it is necessary to replace this element. It is also recommended to inspect the places for the presence of defects.
  • The rope of the launch system. The rope should be examined for wear and injuries. If necessary, replace the part and install it with the pulley.

Diagnostics

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

  • Unscrew the fasteners and remove the lid.
  • Turn a screw that attaches the mechanism to the protective cover.
  • The starter smoothly launch, removing the spring and clamps from it.
  • For examination for wear and defects, a reel with a cable is dismantled.
  • Check the fuel system for water in it. If there is water inside the system, then the fuel fluid must be replaced.
  • Conduct an inspection of the power unit for overflow with fuel fluid. In this case, you need to unscrew and dry the spark plug, pull the starter, dismantling the air damper.
  • Check the spark of spark.
