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 holds the components needed
for assembly as listed in the table below:
Guide bar fitted with bar cover
Toothed chain
Key (if provided)
Documentation
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.
Before assembling the bar, check that
the chain brake is not engaged (par. 5.4).
1. Using the supplied wrench unscrew the nut
or use the tightening 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. Make sure the chain tension adjuster
pin (Fig. 4.D) is correctly inserted in the
corresponding hole in the bar; otherwise use
a screwdriver to tighten the chain tension
adjuster screw (Fig. 4.E), until the pin is
inserted completely (if provided).
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 or knob (Fig. 8.B).
8. Turn the chain tension adjuster screw or act on
the ring nut (Fig. 9.A) to achieve the desired
tension (Fig. 10) (par. 6.1.3).
9. Raise the bar and tighten the guard nut or the
knob securely using the wrench supplied (Fig.
11. A).
5. CONTROLS
5.1 THROTTLE TRIGGER LEVER
It allows the activation of the chain.
The activation of the throttle trigger lever (Fig.
12.A), is possible only after that the throttle lock
buttom is pressed (Fig. 12.B).
The cutting means stops automatically
when the throttle safety lever is released.
5.2 INTERLOCK BUTTOM
The throttle lock lever (Fig. 12.B) allows the
throttle trigger buttom to be used (Fig. 12.A).
5.3 CHAIN BRAKE
This is a safety braking system that blocks the
chain movement when kickback occurs during
EN - 8
Direction in which
the chain runs
