If you notice that your chain saw is dripping gasoline, shut it off immediately, and do not use it until you have found the source of the leak and then repaired it. Gas that drips on your own clothing or onto the wood you are cutting can easily ignite from the spark required to start the chain saw. Avoid a dangerous situation by ensuring that all gasoline stays contained in the tank, fuel and engine lines of this chain saw.
Fuel System Principles
When you’ve drained the fuel to the gasoline tank of the chain saw and opened the machine, the fuel is drawn from the tank, through the fuel lines and to the carburetor. Then, excess fuel yields via the return fuel line to the tank. A leak can occur at one of these points. Fuel can also leak from the primer bulb, or its own fuel lines which pull fuel from the tank and to the motor to aid in starting the chain saw.
To find a gas leak in your chain saw, you will need to inspect it visually. Note of where the fuel originates from your chain saw. If necessary, disconnect the spark plug wire from the spark plug and then dismantle the chain saw to discover the faulty part. A socket set, Phillips-head screwdriver and flat-head screwdriver are common tools necessary to select the string saw apart. Put the components apart carefully since you remove them to avoid losing pieces. If the leak is not apparent, run your finger along suspected components to detect moisture, and smell the residue to make certain that it’s gasoline.
Sources of Leaks
If you are looking for the source of a leak, check out some of the more common areas of the chain saw where leaks often occur. Because lots of the parts of the string saw’s fuel system are made from rubber or plastic, since they age they might harden and decipher. The primer bulb, fuel lines and gas tank are possible sources of gasoline leakage. The cap on the gasoline tank or any of the washers at the system may also fit poorly over time and be the source of the leak. Inspect the carburetor for defective gaskets or dirt which signifies the need for a cleaning of the unit.
Once you’ve identified the source of the gas leak, it is easy enough to fix simply by replacing the defective part or components. Consult the operator’s manual to the chain saw to determine the exact part numbers for the components you require. Always use components made by the producer of the chain saw to get the very best outcomes. If you are worried that you might have trouble downloading the new components in the chain saw once you have removed the previous ones, then make a fast sketch or take photos of each step as you proceed with the repair.
