To check the oil level:
– Place the machine on a flat stable surface,
with the fuel tank cap facing upwards.
– Unscrew the tank cap and check that the oil
level reaches the rim of the filler.
The oil tank capacity is 80 cc (Model 425) or 100
cc (Model 435).
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:
– Place the machine firmly on the ground.
– Remove the guard from the blade (if used).
– Make sure the blade (if used) is not touching
the ground or any other object.
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. 7):
1. Set the switch (1) to position «I».
2. Operate the choke, turning the lever (5) to the
«B» position”.
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. 8).
IMPORTANT To prevent distortions, the drive
tube must not be used as a support for the hand
or knee during startup.
5. Pull 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.
6. 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.
7. When the engine is started, disengage the
choke by turning the lever (5) to the «A» po -
sition.
8. Let the engine run idle for at least 1 minute
before 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 1-4-5-6.
3.2 ADJUSTING THE SPEED
OF THE CUTTING DEVICE (Fig. 7)
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.
