Fitting the bar and chain

455 Rancher, 460 Rancher

Check that the chain brake is in disengaged position by
moving the front hand guard towards the front handle.

Remove the bar nuts and remove the clutch cover (chain
brake). Take off the transportation ring (A).

Fit the bar over the bar bolts. Place the bar in its rearmost
position. Place the chain over the drive sprocket locate it
in the groove on the bar. Begin on the top edge of the bar.

Make sure that the edges of the cutting links are facing
forward on the top edge of the bar.

Fit the clutch cover and locate the chain adjuster pin in the
hole in the bar. Check that the drive links of the chain fit
correctly over the drive sprocket and that the chain is
correctly located in the groove in the bar. Tighten the bar
nuts finger tight.

Tension the chain by turning the chain tensioning screw
clockwise using the combination spanner. The chain
should be tensioned until it does not sag from the
underside of the bar.

The chain is correctly tensioned when it does not sag from
the underside of the bar, but can still be turned easily by
hand. Hold up the bar tip and tighten the bar nuts with the
combination spanner.

When fitting a new chain, the chain tension has to be
checked frequently until the chain is run-in. Check the
chain tension regularly. A correctly tensioned chain
ensures good cutting performance and long life.

455e Rancher

moving the front hand guard towards the front handle.

Remove the knob and remove the clutch cover (chain
brake). Take off the transportation ring.
