Changing Fuel Filter On Stihl Chainsaws: Step-By-Step Guide

If your Stihl chainsaw is having trouble starting or is stalling while in use, it may be time to change the fuel filter. The fuel filter is located in the gas tank and can be accessed by removing the fuel cap. To remove the fuel filter, you will need to use a tool such as a wire or a metal clothes hanger to hook the fuel line and pull it out. Once the fuel line is out, you can remove the fuel filter by hand and replace it with a new one. Push the new filter and fuel line back into the tank, fill it up with gas, and replace the fuel cap.

Place the chainsaw on a level surface and disconnect the spark plug to prevent accidental start-up

To change the fuel filter on a Stihl chainsaw, it is important to take safety precautions. Before beginning any work on the chainsaw, it is crucial to place it on a level surface to ensure stability and reduce the risk of accidental activation. By doing so, you can minimize the chances of injury or damage to the tool. Additionally, disconnecting the spark plug is essential to prevent accidental ignition during the fuel filter replacement process. This step is critical for your safety and should never be overlooked.

When placing the chainsaw on a level surface, choose a stable and flat area that can accommodate the size of the chainsaw. Avoid placing it on uneven ground or inclined surfaces, as this may increase the risk of the chainsaw toppling over or shifting during the repair process. Ensure that the surface is also free from debris or obstacles that could interfere with the stability of the chainsaw.

Once the chainsaw is securely positioned, proceed to disconnect the spark plug to prevent accidental ignition. The spark plug is typically located near the engine, and you can disconnect it by pulling off the spark plug boot. This step ensures that the chainsaw cannot be started unintentionally, providing an additional layer of safety while you work on changing the fuel filter.

After ensuring the chainsaw is securely placed and the spark plug is disconnected, you can proceed with the fuel filter replacement process. It is important to refer to the specific instructions for your Stihl chainsaw model, as the exact steps may vary slightly between different models. However, the general process involves removing the fuel tank cap, siphoning any remaining fuel, accessing the fuel filter, and replacing it with a new one.

Always exercise caution when working with fuel and flammable liquids. Ensure proper ventilation in the work area and avoid any open flames or sources of ignition. Keep a suitable fire extinguisher nearby as an added safety precaution. By following these safety guidelines and taking your time, you can successfully change the fuel filter on your Stihl chainsaw while minimizing potential risks.

Remove the fuel cap by lifting the locking lever and turning it counterclockwise

To remove the fuel cap from your Stihl chainsaw, first set the chainsaw on a level surface and pull off the spark plug boot to prevent an accidental start-up. Then, locate the locking lever on the fuel cap and lift it into the vertical position. With the locking lever lifted, you can now turn the fuel cap counterclockwise to unscrew it.

If your Stihl chainsaw has a plastic strap connecting the fuel cap to the tank, let the cap hang freely once it's unscrewed. If there's no strap, simply set the cap aside. It's important to check if the tank still has gas inside. If it does, use a hand siphon to transfer the gas to a container to prevent spillage.

Now that the fuel cap is removed, you can access the fuel filter inside the tank. The next step is to remove the fuel filter, which can be done using a wire hook or a similar tool. Remember to exercise caution when working with fuel and fumes, and always refer to safety guidelines when performing maintenance on your Stihl chainsaw.

Siphon the fuel into a container if the tank is not empty

Siphoning the fuel out of your Stihl chainsaw is an important step when changing the fuel filter. This is because the filter is located inside the gas tank, so you will need to access the inside of the tank to remove and replace the filter.

To siphon the fuel, you will need to place your chainsaw on a flat surface and set a gas can next to the fuel tank. Then, remove the fuel tank cap by lifting the locking lever to the vertical position and turning it counterclockwise. If the cap is connected to a plastic strap anchored to the tank, let it hang freely. Otherwise, set it aside.

Now, you can insert a hand siphon into the tank and place the opposite end into the gas can. Siphon the fuel from the chainsaw into the gas can until the tank is empty. This step is crucial for safety reasons, as it reduces the risk of fuel spillage during the filter replacement process. It also ensures that you don't waste any fuel, as you can store the siphoned fuel in the gas can for future use.

Once the tank is empty, you can proceed with removing and replacing the fuel filter. This process will involve using a tool, such as a wire or a metal hanger, to reach into the tank and hook the fuel line, allowing you to pull out the old filter and insert the new one.

Form a hook at the end of a 12-inch piece of wire and use it to remove the old filter

To remove the old fuel filter from your Stihl chainsaw, you'll need about 12 inches of 12- or 14-gauge wire. Strip the insulation off the wire to avoid contaminating the fuel tank. Form a hook at one end of the wire and use it to remove the old filter.

Here's a step-by-step guide:

• Reach the wire into the fuel tank: With the chainsaw on a level surface and the spark plug boot removed, take off the gas cap by lifting the locking lever to the vertical position and turning the cap counterclockwise. If the tank still has gas inside, siphon it into a container with a hand siphon. Now, reach the wire with the hook into the tank.
• Hook and pull: Hook the wire around the filter and carefully pull the filter out. You may need a flashlight to help you see inside the tank.
• Hold and work: Hold the fuel line firmly with one hand while you work the filter off. You can use a flat-head screwdriver for this step. Be careful not to let the fuel line fall back into the tank after removing the filter, as it will be difficult to retrieve.

Now that the old filter is removed, you can install a new one. Push the new filter onto the end of the fuel line, ensuring it's secure. Then, let the filter fall back into the tank, fill it up with fuel, and replace the fuel cap.

Push the new filter onto the fuel line and work it in until the rubber touches the base of the filter

When replacing the fuel filter on a Stihl chainsaw, it's important to ensure the filter is securely attached to the fuel line. Here's a detailed, step-by-step guide on how to do this:

Before beginning, make sure you have a new fuel filter ready. Place your Stihl chainsaw on a flat, level surface to ensure stability and reduce the risk of accidental spillage. Remove the fuel tank cap by lifting the locking lever vertically and turning the cap counterclockwise. If the cap is connected to the tank with a plastic strap, let it hang freely; otherwise, set it aside. If there is still fuel in the tank, use a hand siphon to transfer it to a separate container. This step is important for safety and to avoid spillage.

Now, you will attach the new fuel filter. Take the new fuel filter and push it onto the end of the fuel line. You may need to apply some force, but ensure you don't damage the filter or the line. Work the filter onto the line until the rubber end of the line touches the base of the filter. This step ensures a secure connection and helps create a seal to prevent fuel leakage.

Once the new filter is securely in place, carefully let the filter and fuel line fall back into the fuel tank. Ensure the fuel line is flat on the bottom of the tank. Now, you can refill the fuel tank and replace the fuel cap. Make sure the cap is securely tightened to prevent any fuel spillage during operation.

Finally, check that the locking lever on the fuel cap is flush with the top of the cap. If it's not, adjust it until it is flush, ensuring the cap is properly closed. And that's it! You've successfully replaced the fuel filter on your Stihl chainsaw.
