is not engaged; this is done by pulling the front
hand guard right back towards the body of the
machine.

1. BAR AND CHAIN MOUNTING

– Unscrew the nuts and remove the clutch cover
to get to the drive sprocket and point where the
bar is to be fitted (Fig. 1).
– Remove the plastic spacer, (1); this spacer
must be used exclusively when transporting the
machine in its packaging and must not be used
at any other time (Fig. 1).
– Mount the bar (2) by inserting the stud bolts in
the groove and push it towards the back of the
machine body (Fig. 2).
– Mount the chain in the right direction around
the drive sprocket and along the bar rail (Fig.
3). If the tip of the bar has a nose sprocket,
make sure the drive links fit correctly in the
sprocket rims.
– In 3700 - 4000 Models: Check that the chain
tension adjuster pin (3) is fitted properly in the
hole on the bar; if it isn't, turn the chain tension
adjuster screw (4) using a screwdriver until the
pin is completely inserted (Fig. 4).
– Fit the guard back on without tightening the
nuts.

adjuster pin (3a) of the clutch cover is fitted
properly in the hole on the bar; if it isn't, turn
the chain tension ad ju ster screw (4a) using a

2. CHECKS AFTER MOUNTING THE BAR
AND THE CHAIN
– Check the chain tension. The tension is correct
when the drive links do not slip out of the chain
guides if you hold the chain in the middle of the
bar (Fig. 7).
– Using a screwdriver, make the chain run along
the guides to check it moves smoothly without
resistance.
