GB | Operating Instruction
Before starting the engine:
- Place the machine rmly 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.
• Cold starting
NOTE: A “cold” start of the engine means starting it after
at least 5minutes fromwhen it was switched o or after
refuelling.
To start the engine (Fig. 6):
1. Set the switch (1) to «START».
2. Operate the starter, turning lever (5) to «OFF»..
3. Press the primer device button (6) ca. 10 times to
prime the carburettor.
4. Press the safety lever (3), activate the throttle trigger
(2) and hold it in this position using the shutter button
(7 - if provided); then release the safety lever (3).
5. Hold the machine rmly on the ground with one hand
on the power unit, in order not to lose control of the
machine during startup (Fig. 7).
IMPORTANT: To prevent distortions, the drive tube must
not be used as a support for the hand or knee during
startup.
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 y 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) briey activat-
ing 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 ood the engine and make starting
dicult.
If you have ooded 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 - 8.
USE OF THE ENGINE (Fig. 6)
Cutting device speed is regulated by the throttle trigger
(2), located on 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
drive shaft by a centrifugal mass clutch that prevents
the shaft from moving 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
rst 6-8 working hours.
STOPPING THE ENGINE (Fig. 6)
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
8. 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, dam-
aged 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 suering from circulation disorders.
The symptoms can regard the hands, wrists and
ngers and are shown through loss of sensitivity,
torpor, itching, pain and discolouring of or structural
changes to the skin. These eects 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 gener-
ates an average sized electromagnetic eld, 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 using medical
