– t he buckle properly fastened on the left side
(2.4).
The belts must be tensioned so that the load is
evenly distributed on the shoulders.
4.2 MACHINE OPERATING MODES
WARNING! When working, the machine
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 tech-
niques, finding out how to wear the harnesses
correctly, firmly gripping the machine and mak-
ing the movements required by the job.
Choose the most suitable cutting device for the
job to be done and prepare the machine as indi-
cated in chapter 2).

4.3 WORK TECHNIQUES

4.3.1 3 or 4-point blade - "Tri-Arc" 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.
4.3.2 4-point blade (Fig. 13)
Proceed using the machine as a traditional
scythe, with a circular movement of about 60-
90°, thus moving outside the undergrowth, and
so on.
4.3.3 Cutting line head
WARNING! Use ONLY nylon lines. The
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 pe-
riodically and remove the weeds wound round
the machine, so as to prevent the drive tube
from overheating due to the grass caught under
the guard.
Remove the caught-up grass with a screwdriver
to allow the rod to be properly cooled.
WARNING!
sweeping, tilting the cutting line head. The
power of the engine could throw objects and
small stones 15 metres or more, causing
damage or injuries to people.
a) 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 dis-
tance from the ground.
For heavier cutting it can be useful to tilt the cut-
ting line head by about 30°.
WARNING! Do not work in this way if
there is the possibility of causing objects to
be thrown, which could harm people, animals
or cause damage.
b) Precision cutting (Trimming)
Keep the machine slightly tilted so that the low-
er 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 dis-
tance from the operator.
c) Cutting near fences/foundations
(Fig. 15)
Slowly move the cutting line head near fenc-
es, posts, rocks, walls, etc. without hitting them
hard.
If the line strikes a solid object it could break or
become worn; if it gets tangled in a fence it could
break abruptly.
In any case, cutting around pavements, founda-
tions, walls, etc. can cause greater wear than
normal to the line.
d) Cutting round trees (Fig. 16)
Walk round the tree from left to right, approach-
ing the trunks slowly so as not to strike the tree
with the line and keeping the cutting line head
tilted forward slightly.
Remember that the nylon line could lop off or
damage small shrubs and that the impact of the
