MAINTENANCE
ADJUSTING THE CHAIN TENSION
Turn the bar nuts clockwise to secure. Re-tension the chain whenever the ats on the drive links
hang out of the bar groove.
Flats on drive links
WARNING
Never touch or adjust the chain while the motor is running. The chain is very sharp. Always wear
protective gloves when performing maintenance on the chain.
WARNING
A chain tensioned while warm may be too tight upon cooling. Check the “cold tension” before next
use.
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. (1.3 mm) out of the bar groove.
NOTE: New chains tend to stretch; check the chain tension frequently and tension as required.
