during refilling.
– C arefully open the fuel tank cap to allow the
pressure inside to decrease gradually. Use
a funnel to refill and avoid filling the tank to
the brim.
WARNING!
Always close the fuel tank
cap firmly.
WARNING!
Immediately clean all traces
of fuel which may have dripped on the ma-
chine or the ground and do not start the en-
gine until the petrol fumes have dissipated.
3. USING THE MACHINE
3.1 STARTING THE MACHINE
WARNING!
The machine must be started
in an area at least 3 metres from where you
refilled the fuel tank.
Before starting the engine:
– P lace the machine firmly on the ground.
3.1.1 Cold starting
WARNING!
A "cold" start of the engine
means starting it after at least 5 minutes from
when it was switched off or after refuelling.
To start the machine (Fig. 5):
1. Set the switch (1) to position «I».
2. O perate the choke, turning the lever (4) to the
«B» position".
3. P ress the primer device button (5) 3 or 4 times
to prime the carburettor.
4 P ress the safety lever (3), activate the throttle
trigger (2) and hold it in this position using
the shutter button (7); then release the safety
lever (3).
5. H old 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. 6).
IMPORTANT To prevent distortions, the drive
tube must not be used as a support for the hand
or knee during startup.
6. P ull the starter grip slowly for 10 - 15 cm un-
til you feel some resistance, then tug it a few
times until you hear the engine turn over.
IMPORTANT To avoid breaking the starter ca-
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.
7. Pull the starter grip again until the engine
starts as normal.
WARNING!
Starting the engine with the
choke engaged causes the cutting device to
move, only stopping when the choke is dis-
connected.
8. B riefly activate the throttle (2) to bring the
engine down to minimum, with the lever (4)
which will move automatically to the «A» po-
sition.
9. L et the engine run idle for at least 1 minute be-
fore using the machine.
IMPORTANT If the starter grip is pulled repeated-
ly with the choke on, it may flood the engine and
make starting difficult.
If you have flooded the engine, remove the spark
plug and gently pull the starter grip to eliminate
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 1-5-6-7.
3.2 ADJUSTING THE SPEED
OF THE CUTTING DEVICE (Fig. 5)
Cutting device speed is regulated by the throttle
trigger (2), located on the rear handgrip (6).
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. 5)
To stop the machine:
– R elease the throttle trigger (2) and allow the
engine to run idle for a few seconds.
