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 pre-
vents the shaft from moving when the engine is run-
ning at minimum speed.
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.
Avoid using the engine at full
power for the first 6-8 working hours.
STOPPING THE ENGINE (Fig. 8)
To stop the engine:
– Release the throttle trigger (2) and allow the en-
gine to run idle for a few seconds.
– Set the switch (1) to «STOP».
When you have reduced
speed to a minimum, it will take a few sec-
onds for the cutting device to stop
IMPORTANT
3. Press the primer device button (6) 3 or 4 times
to prime the carburettor.
4. Hold the machine firmly on the ground with one
hand on the power unit, in order not to lose
control of the machine during startup (Fig. 9).
To prevent distortions, the
drive tube must not be used as a support for the
hand or knee during startup.
5. Pull the starter rope slowly for 10 - 15 cm until
you feel some resistance, then tug it hard a few
times until you hear the engine turn over.
To avoid breaking the starter
rope, do not pull the whole length of it or let it slide
along the edge of the cable guide hole. Release the
starter gradually, to avoid letting it fly back uncon-
trollably.
6. Pull the starter rope again until the engine starts
as normal.
Starting the engine with
the choke engaged causes the cutting device
to move, only stopping when the choke is dis-
connected.
7. When the engine is started, disconnect the
starter by turning the lever (2) to «RUN».
8. Briefly activate the throttle (2) to bring the engine
down to minimum, with the switch (1) which will
move automatically to the «RUN» position.
9. Let the engine run idle for at least 1 minute be-
fore using the machine.
If the starter rope is pulled
repeatedly with the choke on, it may flood the en-
gine and make starting difficult.
If you have flooded the engine, remove the spark
plug and gently pull the handle on the starter rope
to eliminate any excess fuel; then dry the spark plug
electrodes and replace it on the engine.
• Hot starting
When hot starting (immediately after stopping the
engine):
– Set the switch (1) to position «RUN», then follow
points 4 - 5 - 6 – 9 in the previous procedure.
