How To Check Chainsaw Crankshaft Bearings For Wear
Filter
“Rich” or “lean” fuel mixture will sooner or later cause a breakdown. Perhaps even costly. To prevent this from happening, it will be useful to regularly check the filter for scuffs, as well as for a breakthrough of the filter cloth itself.
Malfunction of other systems
In some cases, users of chainsaws note other problems that do not significantly affect the operation of the tool.
Gasoline flows from the chainsaw
If gasoline drops periodically appear on the body of the chainsaw, then it is necessary to check the tightness of the fuel tank. Over time, it may dry out. Or the gasket “hardened” and it can no longer perform its direct function.
If full-fledged gasoline streams appear, then there is a high probability that you will have to change the burst hose connecting the carburetor and the fuel tank.
Exhaust system and muffler malfunctions
With prolonged active work with a chainsaw, the walls of the exhaust pipe can become covered with carbon deposits, which interferes with the free exit of exhaust gases.
The main causes of excessive fouling are:
- incorrect ratio of gasoline / oil in the fuel mixture;
- using low quality oil for the fuel mixture.
Read the instructions for your chainsaw carefully and use an oil that meets the requirements of the tool manufacturer. To make a fuel mixture, use only the proportion of oil to gasoline specified in the instructions.
Chainsaw carburetor malfunction.
The chainsaw carburetor is a rather complex device that is responsible for supplying the fuel mixture with the correct degree of enrichment. The carburetor requires correct adjustment, inspection, and if it is necessary to repair the carburetor, it is recommended to contact highly qualified specialists.
Depressurization of the carburetor and blockage of the nozzle
Over time, the screws securing the carburetor cover may loosen or the gaskets become unusable. A clogged filter or improper replacement can lead to clogging of the nozzles. All this also negatively affects the operation of the chainsaw and reduces the service life.
To prevent this, it is sufficient to periodically inspect the saw and, if necessary, evenly tighten the screws.
Chainsaw not developing full power
In addition to the problem discussed above with a lack of gasoline or air entering the cylinder, the reason for the weak power may be a clogged muffler.
If you do not periodically clean the muffler clogged with combustion products, then the problem of poor engine power may not be the only one.
Why does the chainsaw smoke
Most often, excessive smoke appears when excessive oil is added to the fuel mixture, which does not have time to completely burn out. You should also check if the carburetor settings are out of order.
Chainsaw muffler malfunction
It often happens that during prolonged operation, the walls of the exhaust pipe become covered with carbon deposits, which prevents the free exit of exhaust gases.
In this case, remove the muffler (if possible) and wash it with detergents, then dry thoroughly with a hairdryer.
ATTENTION! Carbon deposits contain carcinogens. During dry cleaning, it can enter the lungs and pose a threat to your health.
Carbon deposits are usually caused by an incorrect gasoline-oil ratio or the use of low-quality and incompatible oil.
Carefully read the instruction manual for your chainsaw to prevent this from happening in the future.
Fuel system
Fuel system malfunctions are also quite often the main reason that prevents a chainsaw from working as efficiently as possible. First of all, you need to check the quality of the fuel mixture.
Some owners prefer to use a non-recommended brand of gasoline, but alcohol-based solutions or add more oil than is required.
Why doesn’t gasoline come from the chainsaw reservoir to
carburetor? There is only one reason, the formation of a vacuum in the tank. Solution to the problem, pull out the snow-white plug, clean
How to check and replace the fuel filter
To check the current state of the fuel filter, you must perform the following steps:
- Remove the fuel hose from the carburetor fitting and direct it into a working container.
- Press several times on the so-called “swap”.
If the gasoline comes unevenly and jerky, then it’s time to put in a new filter element. This is done quite simply:
- The fuel tank cap is unscrewed.
- Using tweezers or any other device, the filter itself is removed.
- Having disconnected the old filter, you must put a new one and lower it into the fuel tank.
How to clean an air filter
If sufficient air is not supplied, the fuel mixture becomes too rich, which leads to malfunction of the engine. Regular purging of the air filter, and in especially advanced cases, washing in soapy water will avoid such problems.
Please note that rinsing in acetone, gasoline or other aggressive solutions is not allowed. This can lead to a violation of the integrity of the filter element.
Depressurization of the carburetor and blockage of the nozzle
Over time, the screws that secure the carburetor cover can loosen or the gaskets become unusable. A clogged filter or improper replacement can lead to clogging of the nozzles. All this also negatively affects the operation of the chainsaw and reduces the service life.
To prevent this, it is sufficient to periodically inspect the saw and, if necessary, evenly tighten the screws.
Malfunction of undefined category
In some cases, the owners of chainsaws have to solve more complex problems to fully restore the functionality of their cutting tool.
