ADJUSTING THE CHAIN TENSION
See Figures 15 - 16.
WARNING:
Shut off the motor, wait for all moving parts to
stop, and remove the battery pack. Never touch
or adjust the chain while the engine is running.
The saw chain is very sharp. Always wear pro-
tective gloves when performing maintenance
on the chain. Failure to follow these instructions
can result in serious personal injury.
Proper chain tension is critical to the performance
of your chain saw. Always check chain tension
before using the saw and periodically until the
work is complete.
A cold chain is correctly tensioned when there is
no slack on the underside of the guide bar. The
chain should be snug, but still able to be turned
by hand without binding.
A warm chain is correctly tensioned when the flats
on the tie straps hang approximately .050 inches
out of the bar groove.
If adjustment is needed:
Loosen the chain cover screw to finger tight.
Raise the tip of the guide bar and continue to
hold up until the end of this procedure.
Turn the chain tensioning screw clockwise until
the flats on the tie straps of the chain contact
the bar, making sure the drive links are seated
inside the bar groove.
Retighten the chain cover screw securely.
Release the tip of the guide bar and verify the
chain is now correctly tensioned using the
guidelines above.
NOTE: If the chain is too tight and will not ro-
tate, loosen the chain cover screw slightly, then
turn the chain tensioning screw 1/4 turn coun-
terclockwise. Lift up the tip of the guide bar,
retighten the chain cover screw securely, then
verify the chain will now rotate without binding.
NOTE: New chains tend to stretch; check the
chain tension frequently and adjust as needed.

A chain tensioned while warm may be too tight
upon cooling. Check the “cold tension” before

lated to perform over a wide temperature range
with no dilution required.
