ADJUSTING THE CHAIN TENSION
1. Remove the battery pack before adjusting
the chain tension.
2. Rotate the chain tensioning screw using
the included hex key to adjust the chain
tension. Rotate it clockwise to tighten the
chain and counterclockwise to loosen the
chain (Fig. 3a).
During normal saw operation, the
•
temperature of the chain will increase. The
drive links of a correctly tensioned warm
chain will hang approximately 0.050 in.
(1.3 mm) out of the bar groove (Fig. 3b).
A cold chain is correctly tensioned when
•
there is no slack on the underside of the
guide bar and the chain is snug, but it can be
turned by hand without binding. The chain
must be re-tensioned whenever the flats on
the drive links do not sit in the bar groove
(Fig. 3c).
NOTICE
New chains tend to stretch, check chain
•
tension frequently and tension as required.
A chain tensioned while it is warm may be too
•
tight upon cooling. Check the cold tension
before next use.
