MAINTENANCE

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 ad-

justing 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.
