!working with the chain, in order to protect your hands from injury.

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

Unscrew the bar nut 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. See instructions under the heading Tensioning the chain.

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.
