6. 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.
IMPORTANT: 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 uncontrollably.
7. Slide the choke (5) to «ON» position.
8. Pull the starter rope again until the enginestarts as
normal.
WARNING! Starting the engine with the starter
and/or shutter (if present) engaged causes the cut-
ting device to move, only stopping when the starter
is disconnected.
9. Disconnect the shutter (7 - if provided) briefly acti-
vating the throttle trigger (2), to take the engine back
to minimum speed.
10. Let the engine run idle for at least 1minute before

using the machine.

IMPORTANT: If the starter rope is pulled repeatedly 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 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 en-
gine), follow the procedure indicated above in points
1 - 5 - 6 - 7.
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.
Themovement is transmitted fromthe engine to the drive
shaft by a centrifugal mass clutch that prevents the shaft
frommoving 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
first 6-8 working hours.
STOPPING THE ENGINE (Fig. 8)
To stop the engine:
- Release the throttle trigger (2) and allow the engine to
run idle for a few seconds.
- Set the switch (1) to «STOP».
WARNING! When you have reduced speed to a
minimum, it will take a few seconds for the cutting
device to stop
7. USING THE MACHINE
To respect people and the environment:
- Try not to cause any disturbance.
- Scrupulously comply with local regulations and
provisions for the disposal of waste materials
after sawing.
- Scrupulously comply with local regulations and
provisions for the disposal of oils, petrol, dama-
ged parts or any elements which have a strong
impact on the environment.
WARNING! Prolonged exposure to vibrations
can cause injuries and neurovascular disorders (also
called "Renaud's syndrome" or "white hand"), espe-
cially to people suffering from circulation disorders.
The symptoms can regard the hands, wrists and
fingers and are shown through loss of sensitivity,
torpor, itching, pain and discolouring of or structural
changes to the skin. These effects can be worsened
by low ambient temperatures and/or by gripping the
handgrips excessively tightly. If the symptoms oc-
cur, the length of time the machine is used must be
reduced and a doctor consulted.
WARNING! This machine's starter unit gene-
rates an average sized electromagnetic field, but it is
not however possible to exclude the possibility of in-
terference on any active or passive medical devices
that operators may be wearing; this could be risky
for their health conditions. All those usingmedical
devices should always consult their GP, or the devi-
cemanufacturer, before using this machine.
WARNING! Always wear suitable clothing when
using the machine. Your dealer can provide you with
all the information on themost suitable accident-
prevention devices to guarantee your safety.
USING THE WEBBING (Fig. 10)
WARNING! The machine must always be used
connected to the webbing worn correctly. Frequently
check the efficiency of the quick release mechanism
used to quickly free the machine from the belts in
case of danger.
The webbingmust be put on before connecting the
machine to the special coupling and the beltsmust be
adjusted to suit the operator's height and stature.
If the machine has more than one coupling hole, use the
most favourable point for keeping the machine balanced
when working.
Always use webbing suited to the weight of themachine
and the cutting device used
- the single or double beltmodels can be used for
