Operation Manual
USE OF THE ENGINE (Fig. 8)
Cutting device speed is regulated by the throttle
trigger (2), located on the rear handgrip (4) or the
right handgrip (4a) of the handlebar.
The throttle trigger only works if the lockout (3) is
pressed at the same time.
The movement is transmitted from the engine to
the drive shaft by a centrifugal mass clutch that
prevents the shaft from moving when the engine
is running at minimum speed.
WARNING!
Do not use the machine if
the cutting device moves when the engine is
running idle; in this case, contact you dealer.
The correct running speed will be achieved by
pressing the throttle trigger (2) as far as possible.
IMPORTANT
Avoid using the engine at full
power for the rst 68 working hours.
