Changing Fuel Filters In Poulan Chainsaws: Step-By-Step Guide

Changing the fuel filter in a Poulan chainsaw is a straightforward process that can be done in a few simple steps. It is important to maintain the fuel filter to ensure the chainsaw's performance and safety. The fuel filter is located inside the fuel tank and is weighted to allow it to move around and stay submerged in fuel. It is responsible for removing dirt and debris from the fuel, preventing the carburetor's tiny fuel passages from getting clogged. A clogged fuel filter can restrict fuel flow, causing the engine to not start or perform poorly. To replace the fuel filter, one must first remove the fuel cap and use a wire hook to retrieve the fuel line containing the filter. Long-nosed pliers can then be used to remove the filter from the fuel line. A new fuel filter is installed onto the fuel line, which is then tucked back into the fuel tank before reinstalling the fuel cap.

Drain the fuel tank

To drain the fuel tank of your Poulan chainsaw, you'll need to follow these steps:

Firstly, locate the fuel tank. It is usually situated near the rear handle of the chainsaw. Once you've found it, the next step is to empty the tank completely. This is important to avoid any spills or leaks while you're working on the chainsaw. Make sure you have a suitable receptacle to hand for the drained fuel.

Now that the tank is empty, you can begin the process of replacing the fuel filter. The fuel filter is attached to a length of fuel line inside the fuel tank. To access it, you will need to remove the fuel cap from the tank. This will allow you to retrieve the fuel line containing the fuel filter.

With the fuel cap removed, you can now focus on the fuel line and filter. Using a sturdy wire, create a hook at the end by curving it. This will be your retrieval tool. Carefully insert the wire hook into the fuel tank and use it to retrieve the fuel line that houses the fuel filter.

Once you have a hold of the fuel line, you can proceed to remove the fuel filter from it. Long-nosed pliers may be useful here to help you get a grip on the filter and carefully detach it from the line.

With the old fuel filter removed, you can now discard it appropriately and prepare to install the new fuel filter. But before you do so, take a moment to inspect the fuel line for any signs of damage or degradation. Over time, fuel lines can be affected by the fuel and environmental factors, so it's important to ensure the line is in good condition.

If the fuel line looks intact and undamaged, you can proceed to the next step.

Remove the fuel cap

To remove the fuel cap from your Poulan chainsaw, you'll need to follow these steps:

• Prepare the chainsaw: Place the chainsaw on a flat surface and ensure it is switched off and cooled down.
• Locate the fuel cap: The fuel cap is usually found on top of the fuel tank, which is typically located near the rear handle of the chainsaw.
• Unscrew the fuel cap: Using your fingers or a suitable tool, carefully unscrew the fuel cap in a counter-clockwise direction. If the cap is tight, you can use a cloth or rubber glove for a better grip. Do not use excessive force to avoid damaging the cap or the threads.
• Set the fuel cap aside: Once the fuel cap is removed, place it in a safe location to avoid misplacing it. You will need it again when you reinstall the fuel filter.
• Check the fuel level: Before proceeding, check the fuel level in the tank. If the tank is more than half full, consider draining some fuel or siphoning it out to avoid spills during the fuel filter replacement process.

Remember, working with fuel can be dangerous, so ensure you are in a well-ventilated area and avoid open flames or sparks.

Remove the fuel filter

To remove the fuel filter from your Poulan chainsaw, you will need to first locate the fuel tank, which is usually near the rear handle. It is important to empty the fuel tank to avoid any spills or leaks during the process.

The fuel filter is attached to a length of the fuel line inside the fuel tank. To access it, you will need to remove the fuel cap and use a tool to retrieve the fuel line. One method is to create a hook at the end of asturdy wire and use this to hook the fuel line and pull it out. Alternatively, you can use needle-nose pliers to carefully detach the fuel line.

Once you have accessed the fuel line, you can remove the fuel filter from the line using long-nosed pliers. It may be helpful to have a container or tray to place the removed parts in, so they remain together and do not get lost.

It is important to note that the fuel filter should be replaced at least yearly, and inspected often. A clogged fuel filter will restrict the flow of fuel, causing the engine to not start or run poorly.

Install the new fuel filter

To install the new fuel filter in your Poulan chainsaw, follow these steps:

Firstly, ensure you have purchased the correct fuel filter for your specific Poulan chainsaw model. The fuel filter is located inside the fuel tank, so you will need to have drained the fuel tank before beginning this process. It is also important to wear safety gloves and glasses to protect your hands and eyes during the installation.

Now, take your new fuel filter and attach it to the end of the fuel line inside the fuel tank. This is a crucial step as it ensures that the fuel filter will remain submerged in fuel, allowing it to effectively remove dirt and debris, and prevent clogging. Use needle-nose pliers to carefully attach the fuel filter if necessary.

Once the fuel filter is securely attached to the fuel line, tuck the fuel line, along with the new filter, back into the fuel tank. Make sure that the fuel line is not kinked or bent, as this can restrict the flow of fuel.

Finally, check that the fuel filter and fuel line are securely in place and reinstall the fuel cap. Tighten the cap to ensure that it is properly sealed.

By following these steps, you will have successfully installed a new fuel filter in your Poulan chainsaw, ensuring optimal performance and a well-maintained machine.

Reassemble the unit

Now that you have installed the new fuel filter, it's time to reassemble the unit. Here is a detailed, step-by-step guide to help you through the process:

• Reinstall the fuel cap: Install and tighten the fuel cap securely. This will ensure that the fuel remains contained within the tank.
• Reinstall the carburetor: Connect the incoming fuel line, usually green in colour, to the intake nipple at the bottom of the carburetor. This is where the fuel will enter the carburetor from the tank.
• Connect the fuel tank purge line: This line helps regulate the fuel pressure and returns excess fuel to the tank. Connect it to the outlet on the top of the carburetor.
• Slide the carburetor onto the mounting posts: Position the carburetor carefully onto the two mounting posts on the engine. Ensure it is securely seated.
• Connect the carburetor to the intake tube: Press the carburetor assembly back towards the engine until the intake tube is fully seated against both components. This creates a sealed connection for the fuel flow.
• Reconnect the throttle linkage: Reattach the throttle linkage to the carburetor linkage. This linkage allows you to control the engine speed. Pull and hold the throttle trigger to expose the attachment point for the trigger portion of the throttle linkage.
• Reinstall the air filter housing: Position the air filter housing over the carburetor mounting posts. Secure it in place using the provided nuts and screws. This housing protects the air filter and ensures proper airflow to the engine.
• Install the air filter: Place the air filter back into its housing. This filter cleans the incoming air, preventing debris from entering the engine.
• Install the air filter cover: Secure the air filter cover in place. This cover protects the air filter from dust and debris.
• Reinstall the top cover: Place the top cover back onto the chainsaw, securing it with the screws. This cover protects the internal components of the chainsaw.

Your Poulan chainsaw should now be fully reassembled with a new fuel filter installed. Remember to follow all safety precautions when operating your chainsaw and always wear the appropriate protective gear.
