Chainsaw Power Tool

Chain keeps popping off chainsaw
– dull chain
– worn chain
– loose bar nuts

Chainsaw stalling can be caused by a dull chain, low oil level, dirty air filter, or a clogged fuel filter.

Pawls break in Stihl chainsaws due to a variety of factors, including 1) excessive force on the pawl, 2) improper lubrication, 3) worn or damaged pawl, 4) loose or damaged pawl spring.

The chain is too loose, causing it to come off the bar. Tighten the chain by turning the bar-tensioning screw clockwise until the chain is snug against the bar.

The chain is too loose because the tensioner is worn out or not adjusted correctly. To tighten the chain, loosen the bar nuts, then turn the tensioner screw clockwise until the chain is snug against the bar. Tighten the bar nuts and recheck the chain tension.

Chainsaw chain dulls quickly due to friction and heat from cutting. Avoid dulling by sharpening regularly, keeping chain oiled, and using correct bar speed for cutting material.

Chainsaw gets stuck because of dull chain, low oil level, or pinched chain. Lubricate chain, sharpen chain, or adjust chain tension.
