Repairs to the fuel system

Fuel may not enter the cylinder for the following reasons:

  • Fuel filter clogged. You should remove the fuel hose and check how the fuel flows. If the jet is weak, you may need to clean the filter. Take it out through the fuel filler plug and clean it; if it is very dirty replace it with a new one. It is recommended that the fuel filter should be changed every three months as a preventive measure.
  • The breather plug (hole in the fuel tank lid) is clogged. Check also by disconnecting the hose, in case of blockage clean it with a needle.
  • No or insufficient quantity of fuel. There can be several reasons for malfunction. The first cause is a clogged air filter. Air is not getting to the carburettor in the right quantity and engine operation is disturbed because of too rich fuel mixture. A dirty filter is carefully removed, cleaned and washed in water, then dried and reinstalled.

Another reason is that the carburetor is not properly adjusted. There are three screws for adjustment.

Timely replacement of the fuel filter ensures proper fuel supply

The fuel hose and the choke actuator have to fit tightly on the pipe joints

The throttle lever cable should be in place

It is important to follow the instruction manual or you could make things worse.

In the chainsaw design, the starter is responsible for proper starting of the tool’s engine

Over time, chainsaw owners find it necessary to repair this important assembly. And, the sooner the fault can be eliminated, the less the other important parts and mechanisms of the tool will succumb to wear

chain saw starter mechanism

The starters on most chain saws are of the same design. That’s why some stores offer customers universal starters that will fit on models from STIHL, Husqvarna, Partner. Nevertheless, some differences from most have domestic chainsaw starters Ural or Lesnik.

As standard the chain saw starter consists of a number of parts.

A protective cover is placed on top of all the components of the starter. The original principle of operation of most starting mechanisms is also practically the same. In a special groove in the chainsaw housing is a handle that holds the cable. By sharply lifting the handle the latter is understood. At this point, a ratchet actuates, which transmits the force through the drum to another drum with splines, located on the engine shaft.

When pulling the standard cable the chainsaw motor shaft starts to rotate, which leads to the compression of the existing fuel mixture, located at that time between the cylinder head and the standard piston.

As the volume of the internal combustion engine cylinder grows, the amount of fuel mixture consumed, which is required for its future ignition, simultaneously increases. Accordingly, the operator of a high-powered saw needs to make more jerks than the owner of a low-powered household tool. To increase the rate at which the reel returns to its original position, chain saw makers use recoil springs.

Replacing the STIHL chain saw starter cord

STIHL chain saw. is a tool designed for wood harvesting, plant cultivation, landscaping, and other household needs. If any part is defective or the machine is malfunctioning, you need to have your STIHL chain saw repaired.

Most malfunctions

Always use your chain saw according to the instruction manual so that it will last a long time and not break down. All STIHL chain saw faults can be independently identified and repaired. Let’s look at the main problems that can arise in the components and design of the device, and how to repair the STIHL 180 chain saw with your own hands.

Fills the spark plug

If you notice that the spark plug is leaking on your STIHL chain saw, the fuel system may be faulty. The engine should be run on a mix of gasoline and oil. If the mixture is bad, there is a decrease in power, the cylinder overheats, and the saw systems wear out. Wet spark plug on your STIHL chain saw is caused by an imbalance in the fuel mixture. Lack of air in the mixture prevents proper combustion of the emulsion.

Use of low-grade gasoline can lead to engine wear.

Spark blurring also causes use of 4-stroke oil and piston wear. If this problem occurs, remove the fuel cap and adjust the fuel supply. Air intake must be in good working order. A clogged filter should be blown out, but it is better to replace it. To learn how to properly clean the filters, see your chain saw’s manual.

The device and principle of work of a chainsaw starter

Most of the well-known chainsaw manufacturers equip their products with starters that work on basically the same principle. It works like this: in the groove in the chain saw’s body there is a handle with a cord running through it. When the handle is suddenly lifted, the cord is pulled through, which engages the drum in the ratchet mechanism. This actuates a cylinder with studs, which is located on the shaft. During this action the crankshaft makes a couple of revolutions which causes a compression of the fuel mixture that is between the cylinder head and the piston at that moment. When the handle is lowered, on the contrary, the ratchet and the studs lose their contact, which causes the shaft to stop.

Increasing the power of the chainsaw increases the amount of fuel mixture, which should ignite when the chainsaw is started. In such a case, you need to increase the number of jerks of the starter cord to start the engine. To accelerate the return of the drum mechanism, manufacturers use a special steel starter return spring, which has excellent elasticity. Leading brands also use other methods to make starting a chainsaw easier:

  • Pre-enrichment of the fuel mixture by means of a separate flap;
  • Installation of an automatic decompression valve, which allows the pressure inside the chainsaw cylinder to be lowered;
  • Installing a primer designed to prime the fuel before starting the engine.

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

How to Properly Put a Starter on a Chainsaw

How to start a chainsaw: a couple of effective ways

Chainsaws vary in design features, but in most cases the principle of assembly follows two standard schemes. Many devices in the manual contain information about the need to turn on the emergency brake before starting the on/off procedure.

First, it is necessary to master the plant and learn basic troubleshooting techniques, then one will have full control of the unit.

A brief overview of the plant’s design

The chainsaw is powered by. This is a simple device whose design has no special bells and whistles. It usually runs fine even in harsh conditions.Read the factory device Functionality is provided by the structural elements:

  • The carburetor engine (cf. Adjusting the carburetor).
  • Centrifugal clutch type.
  • Ignition system, virtually contactless in all units.
  • A carburetor that adds air to the fuel mixture.
  • Fuel system. Its standard device consists of a hose, filter and gas cylinder, but sometimes it also has additional parts.
  • Starter.
  • Dash.
  • Chain (ref. Chain oil).
  • Tensioning mechanism and chain brake (cf., How to sharpen the chain).

Step by step instructions

When the brake is activated, the assembly process is much slower, so it is also safer and more convenient to engage the gear without using brake equipment.

If a person is not confident in his knowledge and accuracy, then the brake should be activated in reverse. If the procedure is correct, the device does not start, the mechanism does not make it dangerous for human action.

  • Before you start the gasoline, you need to move the flap, which acts as a control lever, to the bottom, compared to the optimal position. First press the gas button. Only if this condition is met, it is possible to move the damper normally to the bottom stop.

The starter knob is jerked again then until the system starts. When the device starts to work actively, the high speed is immediately noticeable, because the throttle is at a high level. Remember that sometimes chainsaws are delivered without a starter motor, then all operations with this element.

In our rating, chainsaws by quality, you will find all chainsaws with an optimal price to quality ratio.

  • ignition on. To do this, turn the rocker switch to the right position or flip the switch.
  • You usually need to push the ground to pump more than twice. It is poured with gasoline, after which you need to press the device more than three times.

You need to take the crank of the starter and tighten with sharp movements until the ignition process is heard. It is marked by establishment and almost instantaneous engine shutdown. Then, the flap should be pulled back to its original position, checking its reach to the stop.

Again, the starter handle is jerked to the location of the device. Before carrying out this action, you need to make sure that this is the way to get a chainsaw. Some devices have a new ignition system.

if it does not work

When all the actions are performed in accordance with the established order, and the chainsaw does not start working, then there are failures in its mechanism.

Usually common and easy to fix problems, such as no spark. The clogging of the air filter is a common cause of this phenomenon. To start the chainsaw, you will need to find the cause and take the necessary steps to fix it.

tighten, chainsaw, starter, spring, breakdowns

Only the correct procedures should be followed. If one does not know what to do, one does not need to commit rash. Disassembly of the unit is prohibited, especially care should be taken with the carburetor.

Do not unscrew the screws on it, as if his device caused a breakdown, then without professional equipment it is impossible to repair the chainsaw.

Lists the activities that must be performed in a strict order. Only when moving from one activity to the next can you determine the exact cause of the problem and fix it quickly without damaging other parts. Algorithm of actions performed in case of failures in the creation of the chainsaw:

  • First of all, this is enough for the device to remain. This is especially true for saws that have been in use recently. It is enough to wait no more than 10 minutes, because during this time the mechanism will cool down, and in the absence of other breaks it will easily start. Sometimes it happens that during the establishment, a candle pours on the appliance. If this unpleasant property has occurred, it is enough to wait for a very short pause and repeat all the steps for winding the motor.
  • The housing cover is unscrewed from the air filter remover. The process of planting the device is performed in its absence. Sometimes the reason for the lack of ignition is the contamination of the filter. If ignition has occurred without it, this is the cause. To fix these problems, just wash the filter under running, warm water with soap and water, and then dry it. You can also replace the old element with a new one.
  • The spark plug is removed. There is a spark test. If it does not appear, you need to replace the old candle with a new one. This usually helps, and a spark appears, but in some cases, and when the mixture is replaced, there is no spark.
