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. 21) with the throttle
control lever pressed fully down;
• the wire is automatically released and the wire
cutting knife (Fig. 27.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.1, Fig. 1.E.2).
Proceed as follows:
– stop the machine (par. 6.6);
– take the cap off the spark plug (Fig. 14.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. 14.B)
and allow the engine to idle for a few seconds.
• turn the switch (Fig.14.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.
6.7 AFTER USE
• Detach the spark plug cap.
• When the cutting means has
halted, fit the blade guard;
• Allow the engine to cool before
storing in an enclosed space.
• Clean (par. 7.4).
• Make sure there are no loose or
damaged components. If necessary,
replace damaged components and
tighten any slack screws and bolts.
IMPORTANT Stop the machine
(section .6.6), remove the spark plug cap
(Fig.14.H) and fit the blade guard whenever
the machine is left unattended.
