How do I adjust the chain bar?
For model number RM1425
Hello Allen, thank you for that great question. To adjust the chain bar, follow the following steps:
1. Use a 7/16-inch (11 mm) wrench to slightly loosen the bar-retaining nuts. Do not remove the bar-retaining nuts.
2. Hold the guide bar tip up and use a flat-head screwdriver to turn the chain-tensioning screw. Turn the chain-tensioning screw clockwise to tighten the saw chain. Turn the chain tensioning screw counterclockwise to loosen the saw chain.
3. The desired chain tension depends on the temperature of the saw chain. For cold chain tensioning, the saw chain should fit snuggly against the underside of the guide bar. There should be no sag. For warm chain tensioning, the saw chain will expand as it heats up during operation. The drive links should hang approximately 1/16 inch (1.3 mm) out of the guide bar groove.
4. Hold the guide bar tip up and move the saw chain back and forth along the guide bar. Make sure the saw chain moves freely and is in proper mesh with the sprocket. If the saw chain does not move easily, slowly turn the chain-tensioning screw counterclockwise to loosen the saw chain.
5. Hold the guide bar tip up and securely tighten the bar-retaining nuts.
We hope this helps, good luck with this repair!
