or if it isn't shown at all. A configuration is allowed
if marked with "OK" and/or the  symbol. The
figure shows assembling configurations allowed
for the string head/grass blade attachment (with
the rules defined in the previous paragraph, it is
forbidden to assemble the string head/grass
blade attachment with the locking pin in both left
and right housings, allowing its assembling in the
upper housing only).
Supply of the nylon string
CAUTION! The string cutting blade housed
in the plastic shield will cut the nylon string
to optimum length; a string that is too long
G1. Double handled grip
The grip (A) can be adjusted to suit the needs of
the operator by moving it forward or backward.
Loosen the knob (C), place the handle in the
desired position then tighten the knob (C) again.
CAUTION! The handle assembly (A) can be
folded parallel to the transmission shaft to
facilitate transport and storage of the machine.
Loosen the knob (C), turn the support (B), by 90°
clockwise, fold the handle (A) in the desired posi-
tion and tighten the knob (C).
G2. Delta handle
For your safety, fasten the delta handle in front of the
label placed on the shaft at a distance of at least 18
cm from the rear grip. The handle should be fas-
tened in a comfortable working position. The safety
pole guard should be mounted using the acces-
sories supplied and in the configuration shown in the
figure, in contact with the delta handle.
CAUTION! First read chapter "Safety
Precautions"
CAUTION! Start the brush cutter in a flat
place. During startup stand in a stable posi-
tion. Make sure the blade or nylon string head do
not touch the ground or any obstacles.
CAUTION! Grip the knob of the starter with
one hand and hold the machine in a stable
position with the other. (Take care not to wind the
starter string around your hand) and pull slowly
until you encounter some resistance, then pull the
cord sharply and forcefully (to start the engine
when cold or warm follow the procedures
described).
CAUTION! Do not pull the starter cord all
the way and do not release it abruptly
against the machine as this could damage it.
G. Assembly of grips
H. Starting and stopping the engine
reduces the rotation speed of the engine and
interferes with cutting efficiency, as well as
increasing the risk of injury.
During cutting, the nylon string wears naturally
causing an increase in the speed of the engine
and a reduced cutting capacity. When this hap-
pens, to bring out more string bump the head
against the ground: release the throttle trigger to
reduce the engine speed to less than 4000 rpm.
Tap gently on the ground with the button (A)
as shown in the figure and the string will come
out automatically. Accelerate again. If the string
does not come out make sure there is still some
left and try again.
Bent front grip
CAUTION! The grip acts as a guard when
the special extension is mounted (D). Screw
the side safety guard securely into the threaded
housing on the bent grip as shown in the figure,
whenever you use the cutting blade.
The bent grip (A) can be adjusted according to
the needs of the operator by folding it forward or
backward. Press the grip adjustment knob (B),
place the grip in one of the positions marked with
the notches (C) in a convenient working position
and release the knob (B).
CAUTION! With the blade installed, use the
machine with the grip adjusted in the posi-
tion marked with the first notch only.
CAUTION! Fold the grip parallel to the
machine - in the position of the last notch (C)
- to facilitate transport and storage of the machine.
Startup of cold engine
• H1. Stop switch (A) turned to I opposite the
"STOP" mark.
• H2. Turn the fuel enrichment lever (B) to the
closed position.
• H3. Pump by pressing several times on the
bulb (C) until you see the fuel flow back into the
tank through the tube (D). Pull the starter cord
until the machine starts.
Let the engine run a few seconds holding the
brush cutter still. Grasp the control grip firmly and
accelerate, automatically the enrichment lever will
return to its original position.
CAUTION! The cutting devices are now
rotating.
Startup of warm engine
• H1. STOP switch turned to I (START). Throttle
trigger lever in minimum position (released).
• H4. Enrichment lever (B) in original position.
