impair the safety and efficiency of the
machine. If in doubt, contact your dealer.
Perform all operations
with the engine off.
Before assembling the bar, check that
the chain brake is not engaged (par. 5.7).
1. Unscrew the nut (Fig. 3.A) and remove the
clutch cover (Fig. 3.B) to get to the drive
sprocket and the point where the bar is fitted.
2. Remove the plastic spacer (Fig. 3.C); this
spacer must be used exclusively when
transporting the machine in its packaging
and must not be used at any other time.
3. Mount the bar (Fig. 4.A) by inserting the stud
bolt (Fig. 4.B) in the groove (Fig. 4.C) and
push it towards the back of the machine body.
4. Tilt the machine to make it easier to wind
the chain around the drive sprocket (Fig. 5).
5. Mount the chain (Fig. 6.A) around the
drive sprocket (Fig. 6.B) and along
the bar guide (Fig. 6.C) being careful
to follow the sliding direction.
6. If the tip of the bar is equipped with a nose
sprocket, make sure the drive links are
correctly inserted in the sprocket rims (Fig. 7).
7. Refit the guard (Fig. 8.A), without fully
tightening the nut, making sure the chain
brake lever is inserted correctly (Fig. 8.B)
into its seat in the front hand guard.
8. Check that chain tension adjuster pin
(Fig. 8.C) on the clutch cover is inserted
correctly into the hole on the bar (Fig. 8.D);
if this is not the case, use a screwdriver
to adjust the screws on the belt tension
adjuster until the pin is fully inserted.
9. Turn the chain tension adjuster screw (Fig.
9.A) to achieve the desired chain tension.
10. Raise the bar and tighten the guard nuts
securely using the wrench supplied (Fig. 10).
4.2.1 Checking the chain tension
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. 11).

Position B - the choke is
engaged (for a cold start).

5.3 PRIMER CONTROL BUTTON

Press the rubber button of the primer
to inject fuel into the carburettor
intake manifold to facilitate startup
when the engine is cold (Fig. 13.E).
5.4 THROTTLE TRIGGER LEVER
Used to regulate the chain speed.
The throttle trigger lever (Fig. 12.B) can
only be used if the interlock lever is
pressed simultaneously (Fig. 12.C).
The correct running speed will be
achieved by pressing the throttle trigger
lever (Fig. 12.B) as far as possible.
