comply with these indications to avoid
serious risks or dangers.
For storage and transport purposes, some
components of the machine are not 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
indications 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.
4.1.2 Assembling the blower tube
and control handgrip
1. Insert the flexible hose (Fig. 3.B) in
the air discharge tube (Fig. 3.A) and
use a screwdriver to tighten the clip
and fasten the tube firmly in place.
2. Insert the tube (Fig. 3.C) in the flexible hose
(Fig. 3.B) making sure the overhang (Fig. 3.G)
is facing down. Use a screwdriver to tighten
the clip and fasten the tubes firmly in place.
3. Insert the control handgrip support (Fig.
3.H) in the tube (Fig. 3.C) aligning it with
the overhang (Fig. 3.G). Position the eyelet
(Fig. 3.I) in the overhang (Fig. 3.J).
4. Fasten the control handgrip in place (Fig.
3.K) and tighten the screw (Fig. 3.L).
5. Thread the cable through the
two cable ducts (Fig. 3.M).
6. Align the tube housing (Fig. 3.D) with the
overhang (Fig. 3.N) of the tube (Fig. 3.C).
Push the tube (Fig. 3.C) and turn it 90
degrees clockwise to fasten it firmly in place.
7. Follow the same process described in the two
previous points to assemble the tube (Fig.
3.E) and the end of the blower tube (Fig. 3.F).
4.1.3 Removing blower tubes
IMPORTANT Stop the machine (par. 6.5)
whenever the blowing tube is removed.
According to the tube type:
– If the tube is fastened with an interlocking
overhang, turn it counter clockwise.
– If the tube is fastened with clips,
use a screwdriver to unscrew the
clips and remove the tubes.

5. CONTROLS

5.1 THROTTLE CONTROL LEVER

The throttle control lever (Fig. 4.A) makes it
possible to control the speed of the rotor.
The rotor's speed must be adapted to
the type of job being performed (chapter
6.4.1); it can be adjusted by applying more
or less pressure on the throttle control.
The maximum speed is reached by pressing
the throttle control as far as possible.
5.2 THROTTLE ADJUSTER AND
ENGINE STOP LEVER
The lever (Fig. 4.B) has a double function:
1. Used to start and stop the engine.
The engine stops (Fig. 4.C).
If the lever is positioned in other
directions, the engine can be started.
2. It allows adjusting of the rotor rotation
speed, maintaining the throttle blocked
in the desired position. The rotor rotation
speed can be adjusted by turning the
lever downwards or upwards. The
maximum speed is reached by turning
the lever downwards as far as possible.
