Position the chain so there is a loop at the back
of the bar.
Hold the chain in position on the bar and place
the loop around the sprocket.
Fit the bar flush against the mounting surface
so that the bar studs are in the long slot of the
bar.
Replace the chain cover ensuring that the
adjusting pin in the chain cover is in the bar
chain tensioning pin hole and that both bar
studs are securely in their respective holes in
the chain cover.
NOTE:
The adjusting pin may need to be slightly
repositioned with the chain tensioning screw
so that it is aligned with the position of the bar
chain tensioning pin hole.
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. 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
that the chain will rotate without binding.

saw chain is very sharp. Always wear protective
gloves when performing maintenance on the
chain. Failure to follow these instructions can
result in serious personal injury.
