MAINTENANCE
W A R N I N G
Never touch or adjust the chain while the motor is running. The saw chain is very sharp. Always
wear protective gloves when performing maintenance involving the chain.
ADJUSTING THE CHAIN TENSION (See Figure 29-30)
•
Stop the motor and disconnect from power supply before setting the chain tension.
•
Slightly loosen the chain cover lock knob.
•
Turn the chain tensioning knob clockwise to tension the chain.
NOTE: A cold chain is correctly tensioned when there is no slack on the underside of the guide bar, the chain
is snug, and it can be turned by hand without binding.
• Rotate the chain cover lock knob clockwise to secure. Retension the chain whenever the flats
on the drive links hang out of the bar groove.
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" (1.3 mm) out of the bar groove.
NOTE: New chains tend to stretch. Check the chain tension frequently and tension as required.
C A U T I O N
A chain tensioned while warm may be too tight upon cooling. Check the “cold tension” before
next use.
