MAINTENANCE

ADJUSTING THE CHAIN TENSIO (See Figure 34-35)

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 on the chain.

• Stop the motor and remove the battery from the chain saw before setting the chain tension.

• Slightly loosen the chain cover lock bolt.

• Turn the chain tensioning bolt 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.

•

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.
