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 (8) 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
cutting device to move, only stopping when the
starter is disconnected.
9. Disconnect the shutter (18 - if provided) briefly acti-
vating the throttle trigger (6), 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 - 8.
USE OF THE ENGINE
Cutting device speed is regulated by the throttle trigger
(6), located on the rear handgrip (2).
The throttle trigger only works if the lockout (7) 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 cut-
ting 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 (6) as far as possible.
IMPORTANT: Avoid using the engine at full power for the
first 6-8 working hours.
STOPPING THE ENGINE
- Release the throttle trigger (6) and allow the engine to
run idle for a few seconds.
- Set the switch (15) to «STOP».
WARNING! When you have reduced speed to
a minimum, it will take a few seconds for the
cutting device to stop
Operating Instructions
During break-in period
A factory new machine should not be run at high revs (full
throttle off load) for the first three tank fillings. This avoids
unnecessary high loads during the break-in period. As all
moving parts have to bed in during the break-in period,
the frictional resistances in the engine are greater during
this period. power after about 5 to 15 tank fillings.
During operation
After a long period of full-throttle operation, allow engine
to run for a while at idle speed so that the heat in the en-
gine can be dissipated by flow of cooling air. This protects
engine-mounted components (ignition, carburetor) from
thermal overload.
After finishing work
Wait for engine to cool down. Drain the fuel tank. Store
themachine in a dry place. Check tightness of nuts and
screws (not adjusting screws) at regular intervals and
retighten as necessary.
Maintenance and Storage
Correct maintenance is essential to maintain the original
efficiency and safety of the machine over time.
WARNING! During maintenance operations:
- Remove the spark plug cap.
- Wait until the engine is sufficiently cold.
- Use protective gloves when handling the blades.
- Keep the blade protection device on, except when
intervening directly on the blade.
- Never dispose of oils, fuel or other polluting mate-
rials in unauthorised places.
Cylinder and silencer
To reduce fire risks, periodically clean the cylinder flaps
