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.
The engine may be very warm immediately
after it is shut off. Do not touch. This can cause
burn injuries.
