• This section describes the safety devices
installed on the machine, the controls and
maintenance to perform to keep them in perfect
working order.
• The general description section will help you to
identify the parts described in this section.
• The risk of accidents is greatly increased if
maintenance is not performed regularly or is not
performed professionally. In case of doubts,
contact an authorized service center.
B1 Safety lever
• This device was developed to prevent acciden-
tal pressing of the throttle control trigger A. The
trigger A only works if it is pressed at the same
time as the safety lever B. When the handle is
released, two separate springs return the throt-
tle trigger A and the safety lever B automatically
to their original positions.
B1 Stop button
• When the Stop button C is pressed in the direc-
tion indicated by the symbol, the engine shuts
down.
• To check correct operation, start the engine and
make sure it shuts down when the Stop button
C is switched to the Stop position.
B2 Blade guide
• The blade guide (A) is an important device
developed to prevent accidental contact
between parts of the body and the blades.
• Periodically, check the conditions of the device
and have it replaced, if necessary, by an author-
ized service center.
B3 Hand guard
• The hand guard (B) prevents any accidental
contact of the hands with the blade unit.
• Periodically, and always after any violent impact
to the guard, check its conditions.
B4 Vibration damping system
• The vibration damping system reduces the
transfer of vibrations by means of springs and
shock absorbers in rubber located between the
engine/blades and the handles on the machine.
• Check regularly that the springs and rubber
shock absorbers are properly mounted and do
not exhibit any cracks or distortion.
B5 Muffler
• The muffler is designed to keep noise levels to a
minimum and to direct the engine exhaust
fumes away from the user.

during use and remain so for some time after

the muffler is always correctly fastened to
the machine. Never use the machine with a
