Cold engine start-up (Fig.G)
1. Push the on/off switch
(2)
to the “START”
”I” position.
2. Prime the fuel circuit by operating the priming
pump 10 times
(5)
; the system is primed when
fuel is visible in the pump. If necessary, operate
the pump again.
3. Shift the air control
(7)
to the “close” position
.
4. With your right hand, grab the start-up handle
(8)
, pull slowly until you feel resistance, and
then pull sharply and decisively; release the
handle once the engine has started. If the en-
gine does not start, repeat this operation a few
times. If the engine still does not start, consult
the chapter “Problems, causes and solutions”.
WARNING! During this stage, the cutting de-
vice may start moving.
5. Once the engine is started, shift the air control
(7)
to the “OPEN” position . Note: Do not leave
the lever in the start-up position too long, or the
engine will tend to flood.
Warm engine start-up (fig.G)
1. Push the on/off switch (2) to the “START”
”I” position and be sure the air control (7)
is on ‘OPEN’ position.
2. If necessary, prime the fuel circuit by op-
erating the priming pump 10 times (5); the
system is primed when fuel is visible in the
pump. If necessary, operate the pump again.
3. Pull the start-up handle (8) until the engine
is started.
Switching off the engine (Fig. G)
Release the accelerator and push the on/off
switch
(2)
to the “STOP” “
O
” position.
The motor, the rotating mechanical parts and the
cutting element will rotate a few more seconds
after you switch off the machine; while the
machine is stopping, do not touch any of the
rotating parts.
Running in
During the first 10 hours of operation, do not
strain the motor too much; for this reason, do
not operate the machine empty at the maximum
RPM and during use do not force the machine
by fully throttling up.
We recommend repeating these operations
several times before starting work, in order to
familiarise yourself with the controls as much
as possible.
If you notice any malfunctions, stop the machine
and consult the chapter “Problems, causes and
solutions”.
Turn the machine off when not in use.
USER INSTRUCTIONS
After reading the previous chapters carefully,
apply these instructions scrupulously to obtain
maximum performance.
Proceed calmly so as to become familiar with
all the controls; after having gained sufficient
experience, you will be able to make full use of
its capacities.
SPOOL AND LINE
Only use spools with plastic, round-section trimmer
lines; for the diameter, consult the technical specifi-
cations attached. Using metal lines, chains or other
is prohibited. Using cutting elements not authorised
by this manual causes very serious danger.
A short or used cutting thread means a lower cut-
ting performance; therefore, follow the instructions
for adjusting the length as indicated below.
Using the semi-automatic spool “tap & go”.
- In order to lengthen the thread, tap the mobile
part of the spool on the ground with the engine
switched on.
- The length of the line is automatically adjusted
by the line cutter
(Fig. A pos. 15)
