ADJUSTING THE CHAIN TENSION
1. Stop the motor and remove the battery pack before adjusting the chain tension.
2. Loosen the cover-screw to the point where it is finger tight.
3. Turn the chain-tensioning screw clockwise to tension the chain. See the
"REPLACING THE BAR AND CHAIN" section in this manual for additional
information.
◾ ◾
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 as Fig. 16 shown.
◾ ◾
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. 17).
NOTICE:
New chains tend to stretch;
check chain tension frequently and
tension as required.
NOTICE:
A chain tensioned while it
is warm may be too tight upon cooling.
Check the cold tension before next use.
