when it is at minimum running speed. The motor
should turn over regularly at this speed.
If the carburettor has to be adjusted again, we
recommend you contact your reseller or an
authorised service centre.
BRUSH CUTTER USE
WARNING Read the Safety measures chapter
of this manual very carefully.
METAL DISKS
The 4-pointed disks are suitable for cutting resi-
stant grass over wide areas. To cut grass, use the
brush cutter as you would a lawnmower: cut the
grass by moving the brush cutter from right to left,
then bring it back to the right, keeping it out of the
vegetation, and so on. Mow the grass with circular
sweeping movements of about 60° - 90° (Fig. 16).
The 3-pointed disk is suitable for cutting branches
and small trees with a diameter of 2 cm.
In this case, start cutting the vegetation from above
and bring the cutting head downwards in order to
cut the branches into little pieces (Fig. 17)
WARNING Using metal tools runs the risk of
recoil when the equipment comes into contact
with solid objects (trunks, branches, stones). If
the equipment does bounce back, it will be dif-
ficult to control and may seriously injure the
operator and damage the machine.
CIRCULAR SAW BLADE
WARNING The circular saw blade can only be
used on Duplex brush cutters which do not
bear the warning symbol shown on page 9 and
are fitted with suitable guards. Using a circular
saw blade with brush cutters that bear this war-
ning symbol and/or without suitable guards
exposes the operator to the risk of serious
injury and even death.
The circular saw blade is suitable for cutting resi-
stant hedges, shrubs and small trees with trunks
that do not exceed 6 cm in diameter.
The blade must always be sharp. This increases
the cutting speed and reduces the risk of the blade
stopping.
When working out which way a tree will fall, also
take the wind direction into account.
We do not recommend you use the right-hand area
of the blade (white area in Fig. 18): using this area
runs a high risk of recoil and the blade stopping.

When the blade is brought closer to the trunk to be
cut, the motor must be running at full speed.
To obtain a good result when cutting down small
trees, the cut must be made with a rapid sweeping
movement towards the branch or the trunk to be
cut (Fig. 19).
WARNING Using metal tools runs the risk of
recoil when the equipment comes into contact with
solid objects (trunks, branches, stones). If the
equipment does bounce back, it will be difficult to
control and may seriously injure the operator and
damage the machine. Never bring the blade into
contact with the ground.
LINE HEAD
To cut grass, use the brush cutter as you would a
lawnmower: cut the grass by moving the brush cut-
ter from right to left, then bring it back to the right,
keeping it out of the vegetation, and so on. Proceed
with circular sweeping movements of 60° - 90° (Fig.
20).
The line head must be held just above the ground.
Never press the rotating line against the ground.
Do not force the line against hard objects (stones,
cement, trees etc.), as this will wear the line down
for no reason.
The line bends on contact with obstacles, but may
damage young plants or plants with thin stems.
To work efficiently, the line must protrude from the
head by approximately 12 cm. If the line is too long,
it should be cut with the line-cutting blade.
If the line is too short, it should be lengthened.
1) If the manual head is fitted, loosen the bottom
knob by about 3 turns in a clockwise direction,
pull the two ends of the line until you have the
required length. Refasten the knob by turning it
in an anticlockwise direction. If too much line is
unwound, it is possible to rewind it: loosen the
knob and block the head body, then turn the bot-
tom lid in an anticlockwise direction.
2) If a semi-automatic head is fitted:
remove the lower part of the line head and turn
it one notch anticlockwise (watching the bottom
part of the head).
Then pull the ends of the line out.
Repeat the operation if necessary.
3) If the Tap & Go head is fitted, gently press the
line head against the ground when it is at maxi-
mum speed and the line comes out automati-
cally. Repeat the operation until you have the
correct length.
WARNING When you use the line head, the
guard has to be fitted with a line-cutting blade.
