serious risks or dangers.
IMPORTANT The machine
is supplied without fuel.
6.1 PRELIMINARY PROCEDURES
Before using the machine:
1. place the machine in a stable
horizontal position on the ground;
2. choose the most suitable cutting means
for the job to be done (par. 4.3);
3. perform refuelling. For fuel filling methods and
precautions (see par. 7.2 and paragraph 7.3);
4. wear the harness correctly
(see paragraph 6.1.1).
6.1.1 Using the harness
The harness and straps must be adjusted
to suit the operator's height and stature.
Always use a harness that is suited
to the weight of the machine:
– for machines weighing less than 7.5 kg,
single or double belt models can be used;
– only the double belt model must be used
for machines weighing more than 7.5 kg.
• Models with single belt
The harness must be put on before connecting
the machine to the special coupling.
The belt (Fig. 13.A) must go from the
left shoulder to the right hip.
The belt must be worn with:
– the support (Fig. 13.A.1), the machine
coupling clip (Fig. 13.A.2). and
the quick release clip (Fig. 13.A.3)
positioned on the right side.
• Models with double belt
The harness must be put on before connecting
the machine to the special coupling.
The belt (Fig. 13.B) must be worn with:
– the support (Fig. 13.B.1), the machine
coupling clip (Fig. 13.B.2). and
the quick release clip (Fig. 13.B.3)
positioned on the right side.
– the quick release clip on the
front (Fig. 13.B.3);
– the belts cross-over on the
