MAINTENANCE
 Replace the chain cover and bar mounting nuts.
 Finger-tighten the bar mounting nuts. The bar
must be free to move for tension adjustment.
 Remove all slack from the chain by turning the
chain tensioning screw clockwise until the chain
seats snugly against the bar with the drive links
in the bar groove.
 Lift the tip of the guide bar up to check for sag.
 Hold the tip of the guide bar up and tighten
the bar mounting nuts securely.
The chain is correctly tensioned when there is no
sag on the underside of the guide bar, the chain is
snug, but it can be turned by hand without binding.
NOTE: If chain is too tight, it will not rotate. Loos-
en the bar nuts slightly and turn the tension adjust-
er 1/4 turn counterclockwise. Lift the tip of the
guide bar up and retighten the bar nuts securely.
Ensure that the chain will rotate without binding.

before using the saw and periodically until the
work is complete.

no slack on the underside of the guide bar. The
chain should be snug, but still able to be turned
by hand without binding.
