with the bar and chain dismantled and the oil and
fuel tanks empty.
WARNING!
!
Unpacking and complet-
ing the assembly should be done on a flat and
stable surface, with enough space for moving
the machine and its packaging, always mak-
ing use of suitable equipment.
Disposal of the packaging should be done in
accordance with the local regulations in
force.
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.
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. INSTALLING GUIDE BAR
AND SAW CHAIN
Open the box and install the guide bar and the
saw chain on the power unit as follows (Fig. 2):
– Loosen the nuts and remove the chain cover
(1).
– Fix the support (2) on the rear of power unit by
screw.
– Mount the guide bar then fit the saw chain
around the bar and sprocket.
The machine is supplied
NOTE
Play attention to the correct
direction (3) of the saw chain.
– Fit the chain tensioner nut (4) into the lower
hole (5) of the guide bar, then install the chain
cover, and fasten the mounting nut (6) to finger
tightness.
WARNING!
!
When installing the chain
cover, be sure to fit the hook completely at
the rear end of the cover.
– While holding up the tip of the bar, adjust the
chain tension (7) by turning the tensioner
screw until the tie straps just touch the bottom
side of the bar rail.
– Tighten the nuts (6) securely with the bar tip
held up (12 ~ 15 Nm). Then check the chain for
smooth rotation and proper tension while
moving it by hand. If necessary, readjust with
the chain cover loose.
– Tighten the tensioner screw (7).
2. CHECKS AFTER MOUNTING
THE BAR AND THE CHAIN
– 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. 3).
– Using a screwdriver, make the chain run along
the guides to check it moves smoothly without
resistance.
