4. ASSEMBLY
The safety regulations to follow
are described in chap. 2. Strictly
comply with these instructions to
avoid serious risks or dangers.
For storage and transport purposes, some
components of the machine may not be installed
in the factory and have to be assembled after
unpacking. Follow the instructions below.
Unpacking and completing the assembly
should be done on a flat and stable surface,
with enough space for machine handling
and its packaging, always making use of
suitable equipment. Do not use the machine
until all the instructions provided in the
"ASSEMBLY" section have been carried out.
4.1 ASSEMBLY COMPONENTS
The packaging includes assembly components.
4.1.1 Unpacking
1. Carefully open the packaging, paying
attention not to lose components.
2. Consult the documentation in the
box, including these instructions.
3. Remove all the unassembled
parts from the box.
4. Remove the machine from the box.
5. Dispose of the box and packaging in
compliance with local regulations.
4.2 ASSEMBLY OF THE GUIDE
BAR AND TOOTHED CHAIN
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.
Perform all operations after
removing the battery.
1. Remove the knob (Fig. 3.A) and remove
the chain guard (Fig. 3.B), to access
the drive pinion and bar seat.
2. 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.
3. Mount the chain around the drive pinion (Fig.
5.A) and along the bar guide, being careful
to follow the sliding direction (Fig. 5.B).
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. 6).
4. Check that chain tension adjuster pin
(Fig. 5.C) is inserted correctly in the
hole on the bar; if it isn't, turn the chain
tension adjuster screw (Fig. 5.D), until
the pin is completely inserted.
5. Replace the guard without
fully tightening the knob.
6. Turn the chain tension adjuster screw (Fig.
5.D) to achieve the desired tension (Fig. 7).
7. Raise the bar and tighten the
knob (1) securely (Fig. 8.A).
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. 7)
