 Place the chain drive links into the bar groove

as shown.

 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 clutch cover ensuring that the

adjusting pin in the clutch cover is in the bar

tensioning pin hole and that both bar studs are

in their respective holes in the clutch 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 and fingertighten 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.

 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

that the chain will rotate without binding.
