USING THE MACHINE
– the release in front (2.2);
– the belts cross-over on the operator's back (2.3);
– the buckle properly fastened on the left side (2.4).
The belts must be tensioned so that the load is even-
ly distributed on the shoulders.
• "FLEX" models
Wear the webbing harness like a normal back-
pack.
Tension the belts so that the load is evenly distrib-
uted on the shoulders, fasten the waist belt and
connect the elastic to the plate.
USING THE MACHINE
chine must always be firmly held in both
hands, keeping the power unit on the right of
the body and the cutting group below the line
of the belt.
Before tackling a mowing job for the first time it is
advisable to gain the necessary familiarity with the
machine and the most suitable cutting techniques,
finding out how to wear the webbing correctly,
firmly gripping the machine and making the move-
ments required by the job.
• Choosing the cutting device
Choose the most suitable cutting device for the
job to be done, according to these general indica-
tions:
– the 3point blade is suitable for cutting brush-
wood and small shrubs up to 2 cm in diameter;
– the cutting line head can eliminate tall grass
and non-woody vegetation near fences, walls,
foundations, pavements, around trees, etc. or to
completely clean a particular area of the gar-
den;
– the saw blade (if permitted) is suitable for cut-
ting resistant bushes, shrubs and small trees
with a trunk up to 6 cm.
WORKING TECHNIQUES
a) 3point blade (Fig. 12)
Start cutting above the undergrowth and then move
down with the scything blade so as to cut the brush
into small pieces.
When working, the ma-
b) 4-point blade (Fig. 13)
Proceed using the machine as a traditionalscythe, with
a circular movement of about 60-90°, thus moving out-
side the undergrowth, andso on.
c) Cutting line head

use of metal lines, plasticised metal lines
and/or lines not suitable for the head can
cause serious injuries and wounds.
During use it is advisable to stop the engine peri-
odically and remove the weeds wound round the
machine, so as to prevent the drive tube from over-
heating due to the grass caught under the guard.
Remove the caught-up grass with a screwdriver to
allow the rod to be properly cooled.
for sweeping, tilting the cutting line head. The
power of the engine could throw objects and
small stones 15 metres or more, causing dam-
age and injuries to people.
• Cutting in motion (Scything) (Fig. 14)
Proceed at a regular pace, with a circular motion
similar to a traditional scythe, without tilting the
cutting line head during the operation.
First try cutting at the right height in a small area, so
as to then achieve a uniform cutting height keeping
the cutting line head at a constant distance from the
ground.
For heavier cutting it can be useful to tilt the cutting
line head by about 30°.
there is the possibility of causing objects to be
thrown, which could harm people and animals
and cause damage.
• Precision cutting (Trimming)
Keep the machine slightly tilted so that the lower
part of the cutting line head does not touch the
ground and the cutting line is at the required point,
always keeping the cutting device at a distance
from the operator.
