Fitting the bar and chain

WARNING! Always wear gloves, when
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 guard (A). (34)
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.
Mount the clutch cover and remember to fit 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 with your fingers.
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. (27)
The chain is correctly tensioned when there is no slack on
the underside of the bar, and it can still be turned easily
by hand. Tighten the bar nut with the combination
spanner while holding up the tip of the bar. (28) (29)
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. (25)
