MAINTENANCE
ADJUSTING THE CHAIN TENSION
WARNING
Never touch or adjust the chain while the
motor is running. The saw chain is very sharp.
Always wear protective gloves when performing
maintenance on the chain.
• Loosen the chain cover lock nuts with the
supplied wrench. The chain cover lock nuts do
not have to be completely removed in order to
adjust the chain tension.
• Rotate the chain adjustment screw clockwise
to increase the chain tension and rotate
counterclockwise to decrease the chain
tension.
• Once the chain is at the desired tension,
tighten the chain cover lock nuts.
NOTE: During normal saw operation, the
temperature of the chain increases. The drive
links of a correctly tensioned warm chain will hang
approximately 1/16 in. (1,58 mm) out of the bar
groove.
NOTE: New chains tend to stretch; check the chain
tension frequently and tension as required.
