Adjusting the Chain Tension
1. Stop the motor and remove the
battery pack before adjusting the
chain tension.
2. Loosen the side-cover knob to the
point where it is finger tight.
3. Turn the chain-tensioning adjust
knob clockwise until the chain
seats snugly against the guide bar
with the drive links in the guide bar
groove. The chain is correctly tensioned when there is no sag on the underside of
the guide bar and the chain is snug, but it can be turned by hand without binding.
4. If the chain is too tight to rotate, turn the chain-tensioning adjust knob
counterclockwise to loose the chain tension. Then retighten the chain following
step 3.
5. Retighten the side-cover knob.
◾
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.
◾
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. 28).
NOTICE:
New chains tend to stretch. Check chain tension frequently and adjust
tension as required.
NOTICE:
A chain tensioned while it is warm may be too tight upon cooling. Check the
cold tension before next use.
