CARE AND MAINTENANCE
12. Adjusting the Chain Tension
a. Stop the saw and remove the battery pack
before adjusting the chain tension.
b. Loosen the side-cover knob.
c. Turn the chain-tensioning knob clockwise to
tension the chain. See the section: “
Replacing
the Bar and Chain
” in this manual for
additional information.
• 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. 12a).
• 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.
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.
