CAUTION
Working on the material may cause it to splinter.
Wear eye protection and protective gloves. Wear
breathing protection if no dust removal system is
used.
Splintering material presents a risk of injury to
the eyes and body.
CAUTION
The power tool and the cutting operation generate
noise.
Wear ear protectors. Exposure to noise can
cause hearing loss.
CAUTION
The cutting disc and parts of the machine get hot
during use.
Wear protective gloves when changing
the cutting disc. Touch the machine only at the grips
provided.
You may otherwise burn your hands. Take
care to ensure that the machine, when hot, does
not come into contact with inflammable materials
during transport or storage.
WARNING
Keep other persons approx. 15 m away from your
workplace. Pay special attention to the working
area behind you.
DANGER
Don’t work in closed rooms.
Carbon monoxide, un-
burned hydrocarbons and benzene in the exhaust gas
may cause asphyxiation.
WARNING
When the motor is idling, the cutting disc must
come to a complete stop. If this is not the case, the
idling speed must be reduced accordingly. If this is
not possible or does not achieve the desired result,
the machine must be returned for repair.
WARNING
If you notice that the throttle trigger has jammed,
stop the motor immediately by operating the on /
off switch.
WARNING
After fitting a new cutting disc, the machine must
be allowed to run at full speed under no load for
approx. 1 minute.
WARNING
Before using the machine, check to ensure that the
start / stop switch functions correctly. The motor
must stop running when the switch is moved to the
“stop” position.
1. Stand the machine on a solid surface on the
floor.
2. Move the start / stop switch to the “start” posi-
tion.
3. Press the fuel pump button (P) 2 to 3 times (until
the pump button is seen to be completely filled
with fuel).
4. Press the decompression valve.
5. If the motor is cold, pull the choke lever up-
wards. This activates the choke and engages half
throttle.
6. If the motor is hot, pull the choke lever up and
then push it back down. This engages half throttle
(with no choke).
7. Check that the cutting disc is free to rotate.
8. Hold the forward grip securely with the left hand
and place your right foot in the lower section of
the rear grip.
9. Pull the starter handle slowly with your right
hand until resistance is felt.
10. Pull the starter handle vigorously.
11. When the motor fires for the first time (after 2 to
5 pulls of the starter), move the choke lever back
to its original position.
12. Repeat this procedure, with the choke disen-
gaged, until the motor starts.
NOTE The motor will flood if the starting proced-
ure is repeated too many times with the choke
engaged.
