• Repairing a TOR2525 petrol chainsaw with 142–144 guide bar/chain assembly
• Routine maintenance to maintain correct chain tension and cutting performance
• Replacing a worn or damaged chain tensioner to restore safe operation

Key specifications

• Compatibility: designed for petrol chainsaw TOR2525 and guide bar/chain sizes 142–144
• Function: mechanical chain tension adjustment and retention
• Material characteristics: durable metal/plastic components suitable for outdoor power tool use
• Mounting: replacement part matching standard TOR2525 tensioner mounting points

How to use

Ensure the chainsaw is switched off and the spark plug is disconnected before beginning work. Remove the guide bar cover and loosen the bar nuts to relieve chain tension. Fit the replacement tensioner into the original mounting location, align it with the guide bar and chain, then secure the cover and nuts loosely. Use the tensioner adjustment screw to set the chain with the correct tension: the chain should move smoothly by hand but not hang loosely from the bar. Finally, tighten the bar nuts to the manufacturer's specified torque and recheck chain tension after a short test run.

Usage recommendations

Regularly inspect chain tension before each use and after the first few cuts following installation. Lubricate the bar and chain as recommended by the chainsaw manufacturer and replace the tensioner if threads or adjustment mechanisms show significant wear.
