4. MACHINE ASSEMBLY

IMPORTANT
with the bar and chain dismantled and the oil and
fuel tanks empty.
WARNING!
!
Always wear heavy-duty
gloves when handling the bar and chain.
Mount the bar and chain very carefully so as
not to impair the safety and efficiency of the
machine. If in doubt, contact your dealer.
NOTE
The machine can be assem-
bled in different ways, depending on the bar fas-
tening system and the chain tensioning mecha-
nism.
Before fitting the bar, make sure the chain brake
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

• P 350 - P 400 Models
– 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).
– 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.
– Fit the guard back on, checking that the chain
tension adjuster pin (3) is fitted properly in the
hole on the bar (Fig. 4); if this is not the case,
turn the chain tension adjuster screw (4) using
a screwdriver until the pin is completely insert-
ed.
– Screw down the nuts without fully tightening
them (Fig. 5).
– Turn the chain tension adjuster screw (4) to
adjust the chain tension (Fig. 5).
– Raise the bar and tighten the guard nuts
securely using the wrench (Fig. 6).
The machine is supplied
• P 350Q - P 400Q Models
– Loosen the screws (1), remove the handle (2),
unscrew the knob (3) and remove the clutch
cover to access the drive sprocket and the
point where the bar is fitted (Fig. 7).
– Mount the bar (4) by inserting the stud bolts in
the groove and push it towards the back of the
machine body (Fig. 8).
– Mount the chain in the right direction around
the drive sprocket and along the bar rail (Fig.
9). If the tip of the bar has a nose sprocket,
make sure the drive links fit correctly in the
sprocket rims.
– Fit the guard back on, checking that the chain
tension adjuster pin (5) is fitted properly in the
hole on the bar (Fig. 9); if this is not the case,
adjust the outer ring (6) as necessary until the
pin is completely inserted (Fig. 9).
– Fit the guard back on using the screw (1) and
replace the knob (3) without tightening it too
much (Fig. 10).
– Tighten the chain by rotating the outer ring (6)
clockwise (Fig. 10).
– Raise the bar and tighten the knob (3) secure-
ly, then replace the handle (2) inside the knob
(3) (Fig. 10).
2. TESTS AFTER ASSEMBLY
– Check the chain tension. The tension is cor-
rect when the drive links do not slip out of the
chain guides if you hold the chain in the mid-
dle of the bar (Fig. 1).
– Using a screwdriver, make the chain run along
the guides to check it moves smoothly without
resistance.
– If necessary, adjust the chain tension as indi-
cated below.
• Adjusting the chain tension
P 350 - P 400 models:
– loosen the nuts and use a screwdriver to
regulate the chain tension adjuster screws
(4) as necessary (Fig. 5).
– Raise the bar and tighten the guard nuts
securely using the wrench (Fig. 6).
P 350Q - P 400Q models:
– take out the handle (2), loosen the knob (3)
and adjust the outer ring (6) as necessary
(Fig. 10).
– Raise the bar and tighten the knob (3)
securely, then replace the handle (2) inside
the knob (3) (Fig. 10).
