b. 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
means at a distance from the operator.
c. Cutting near fences/foundations
Move the cutting line head slowly
towards fences, posts, rocks, walls, etc.
without hitting them hard (Fig. 15).
If the line strikes a solid object it could
break or become worn; if it gets tangled
in a fence it could break suddenly.
In any case, cutting around pavements,
foundations, walls, etc. can cause
greater wear than normal to the line.
d. Cutting around trees
Walk round the tree from left to right, approaching
the trunks slowly so as not to strike the tree
with the line and keeping the cutting line
head tilted forward slightly (Fig. 16).
Remember that the nylon line could lop off or
damage small shrubs and that the impact of the
nylon line against the trunk of bushes or trees
with soft bark could seriously damage the plant.
6.4.1.b 3 point, 4 point and 8 point blades:
Start cutting from above the vegetation and then
descend with the mowing blade to cut branches
by chopping them into small pieces (Fig. 17).
6.4.1.c Saw blade (if allowed):
Where permitted, the saw blade
must be used with the specific guard
always fitted (section 4.4.2). The blade
should always be well sharpened
to reduce the risk of kickbacks.
When felling small trees, assess the
direction of fall of the tree when cut, taking
wind direction also into consideration.
To obtain good results when felling small
trees, make the cut with rapid movements
towards the branch or trunk to be cut
with the engine at maximum rpm.
Avoid using the right side of the blade since their
is a high risk of kickback or jamming the blade
in view of the direction of rotation (Fig. 18).
6.4.2 Adjusting the length of the
cutting line head during work
This machine is fitted with a semi-
automatic wire release head.
Head line length should be adjusted:
– when the line is consumed
and becomes shorter;
– when engine rotation seems
higher than normal;
– when cutting efficiency seems reduced.
To release new line:
• hit the cutting line head against the
ground (Fig. 19) with the throttle
control lever pressed fully down;
• the wire is automatically released and the wire
cutting knife (Fig. 24.A) cuts the excess length.

6.5 ADVICE FOR OPERATION

During use, it is advisable to remove cut
vegetation wrapped around the machine at
regular intervals to avoid engine overheating
(Fig. 1.A) caused by grass trapped under
the cutting means guard (Fig. 1.E).
Proceed as follows:
– stop the machine (par. 6.6);
– take the cap off the spark plug (Fig. 11.H)
– wear protective gloves;
– remove the caught-up grass
with a screwdriver to allow the
engine to be properly cooled.
NOTE During the first 6-8 hours of machine
operation, avoid using it at maximum speed.

6.6 STOP

To stop the machine:
• Release the throttle lever briefly (Fig. 11.B)
and allow the engine to idle for a few seconds.
• turn the switch (Fig.11.A) to position "O";
• Wait until the cutting means stops.
When you set the throttle to
idle, it will take a few seconds for
the cutting means to stop.
IMPORTANT Always stop the machine
when moving between work areas.
