til you feel some resistance, then tug it a few
times until you hear the engine turn over.

ble, do not pull the whole length of it or let it slide
along the edge of the cable guide hole. Release
the starter grip gradually, to avoid letting it fly back
uncontrollably.
6. Pull the starter grip again until the engine
starts as normal.

choke engaged causes the cutting device to
move, only stopping when the choke is dis-
connected.

any excess fuel; then dry the spark plug elec-
trodes and replace it on the engine.

3.1.2 Warm starting

When warm starting (immediately after stop-
ping the engine), follow the procedure indicated
above in points 1-4-5-6.
3.2 ADJUSTING THE SPEED
OF THE CUTTING DEVICE (Fig. 9)
Cutting device speed is regulated by the throttle
trigger (2), located on the rear handgrip (4) or the
right handgrip (4) 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 transmission shaft by a centrifugal mass
clutch that prevents the shaft from moving when
the engine is running at minimum speed.
WARNING! The cutting device must not
move when the engine is running idle. If the
cutting device moves when the engine is
running idle, contact your dealer to correctly
regulate the engine.
The correct running speed will be achieved by
pressing the throttle trigger (2) as far as possible.
IMPORTANT Avoid using the engine at full pow-
er for the first 6-8 working hours.
3.3 STOPPING THE MACHINE (Fig. 9)
