CARE AND MAINTENANCE
9. Adjusting the Chain Tension
a. Stop the saw, allow the saw to cool and remove
the battery pack before adjusting the chain
tension.
b. Loosen the side-cover knob.
c. Rotate the chain tensioning knob (O) to tension
the chain. See the section:
“Replacing the
Bar and Chain”
in this manual for additional
information (Fig. 9a).
• 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. 9b).
• 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. 9c).
NOTICE:
New chains tend to stretch, check
chain tension frequently and adjust the tension as
required.
NOTICE:
A chain tensioned while it is warm may
be too tight upon cooling. Check the cold tension
before next use.
