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 nut 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.
