MAINTENANCE

Fit the bar flush against the mounting surface so that the bar studs are in the long slot of the bar.

NOTE: When placing the bar on the bar studs, ensure that the adjusting pin is in the chain tension pin hole.

Replace the clutch 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.

Release the tip of the guide bar and turn the chain tension- ing 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 mount- ing 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 counter- clockwise. Lift the tip of the guide bar up and retighten the bar nuts securely. Ensure that the chain will rotate without binding.

ADJUSTING THE CHAIN TENSION

See Figures 44 - 46.

WARNING:

Never touch or adjust the chain while the motor is run- ning. The saw chain is very sharp. Always wear protective gloves when performing maintenance on the chain.

Stop the engine before setting the chain tension.

Make sure the bar mounting nuts are loosened to finger tight.

Turn the chain tensioning screw clockwise to tension the chain.

NOTE: A cold chain is correctly tensioned when there is no slack on the underside of the guide bar, the chain is snug, and it can be turned by hand without binding.
