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.

NOTE! 

If clutch cover is difficult to remove, replace bar nuts, engage 
brake and rerelease (an audible click will be heard if released 
properly).
