4.1. Chain Adjuster Tensioner Installation

Figure 2: Detail of a single chain adjuster tensioner. This image shows the threaded shaft and the adjustment mechanism of one of the two tensioners included in the kit.

1. Locate the existing tensioner: The chain tensioner is typically located near the guide bar and chain, often accessible from the side cover of the chainsaw.
2. Remove the old tensioner: Depending on your specific Stihl model, this may involve loosening or removing the side cover and then unscrewing or disengaging the old tensioner mechanism. Note its orientation for reassembly.
3. Install the new tensioner: Carefully insert the new HURI chain adjuster tensioner into its designated slot. Ensure it aligns correctly with the guide bar and the chain adjustment pin.
4. Secure the tensioner: Reattach any covers or screws that were removed. Do not fully tighten yet.
5. Adjust chain tension: With the guide bar nuts slightly loose, use the tensioner screw to adjust the chain tension. The chain should be snug against the guide bar but still able to be pulled around by hand. Refer to your chainsaw's original manual for precise tensioning guidelines.
6. Tighten guide bar nuts: Once the tension is correct, fully tighten the guide bar nuts.

4.2. Fuel Line and Fuel Filter Installation

1. Drain fuel tank: Safely drain all fuel from the chainsaw's fuel tank into an approved container.
2. Locate existing fuel line and filter: The fuel line connects the fuel tank to the carburetor. The fuel filter is typically at the end of the fuel line inside the fuel tank.
3. Remove old components: Carefully pull the old fuel line and filter out of the tank. You may need pliers or a hook tool.
4. Install new fuel filter: Attach the new fuel filter securely to one end of the new fuel line. Ensure a tight fit to prevent leaks.
5. Install new fuel line: Feed the fuel line with the attached filter into the fuel tank opening. Guide the filter to the bottom of the tank, ensuring it can draw fuel effectively.
6. Connect to carburetor: Connect the other end of the fuel line to the carburetor's fuel inlet. Ensure all connections are secure and free of kinks.
7. Refill fuel tank: Carefully refill the fuel tank with the appropriate fuel mixture for your chainsaw. Check for any leaks before starting the engine.

5. Operating Considerations

These parts are designed to restore the proper function of your chainsaw. After installation, always perform a functional check:

• Chain Tension: Verify the chain tension is correct before each use. An improperly tensioned chain can be dangerous and cause premature wear.
• Fuel System: Check for any fuel leaks around the new fuel line and filter connections. Ensure the engine starts and runs smoothly, indicating proper fuel delivery.

6. Maintenance

Regular maintenance of these components will extend their lifespan and ensure optimal chainsaw performance:

• Chain Adjuster: Keep the tensioner screw threads clean and lightly lubricated to ensure smooth adjustment. Periodically check for any signs of wear or damage.
• Fuel Filter: The fuel filter should be inspected regularly (e.g., every 25 hours of operation or annually) and replaced if it appears clogged or dirty. A clogged filter can lead to poor engine performance.
• Fuel Line: Inspect the fuel line for cracks, hardening, or leaks. Replace immediately if any damage is observed.
