3. USING THE MACHINE
3.1 STARTING THE MACHINE
Before starting the engine, place the machine on stable ground and make sure blowing or
vacuum tubes are not crushed.
3.1.1 Cold starting
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 engine (Fig. 4):
1. Operate the starter, moving lever (2) to «CHOKE» .
2. Press the primer device button (3) 7 to 10 times to prime the carburettor.
3. Hold the machine firmly with one hand on the handgrip (6), in order not to lose control of
the machine during starting.
4. 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.
5. Switch the lever (2) to the «RUN» position.
6. Pull the starter grip again, and press the throttle trigger all the way (4) until the engine starts
as normal.
7. When the engine has started, press and release the throttle trigger (4) to allow the engine
to run idle.
8. Rev the engine a little using the throttle trigger to warm it up 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 happen to flood the engine, repeat the hot start procedure a few times to eliminate any
excess fuel.
3.1.2 Hot starting
To hot start the engine immediately after it has stopped, follow steps 2 - 3 - 4 - 6 of the above
procedure, making sure the primer (3) is activated 2-3 times only.
3.2 ADJUSTING THE SPEED (Fig. 4)
Rotor rpm must be proportionate to the type of work and regulated by the throttle trigger (4) lo-
cated on the upper handgrip. The throttle trigger can be held in any required position engaging
the throttle setting device (5)..
