When to Replace

• Difficulty adjusting chain tension or the adjustment screw spinning freely.
• Visible stripping or wear on the tensioner screw threads.
• Binding or failure of the tensioner slide to move the guide bar.
• Missing or damaged mounting hardware that prevents the bar from being held securely.

Installation Tips

• Ensure the chainsaw is turned off and the spark plug wire is disconnected before servicing.
• Clean the bar mounting area of wood chips and oil debris to ensure smooth slide movement.
• Lightly lubricate the tensioner screw threads to reduce friction during adjustment.
• Align the tensioner pin carefully with the hole in the guide bar before tightening the side cover nuts.
• Do not overtighten, as this may damage the adjustment mechanism or lead to excessive chain wear.
