Release the tip of the guide bar and turn the
chain tensioning screw 1/2 turn clockwise.
Repeat this process until sag does not exist.
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.
Ensure that the chain brake is not set.
NOTE: If chain is too tight, it will not rotate. Loosen
the bar nuts slightly and turn the tension adjuster
1/4 turn counterclockwise. Lift the tip of the guide
bar up and retighten the bar nuts securely. Ensure
