WARNING
Risk of burns! The muffler becomes very hot during
operation and retains heat for a long time after the engine
has been stopped. This is the case even with the engine
idling. Wear protective gloves and do not touch the
hot muffler! Contact with the hot muffler may result in
severe burns.
WARNING
Risk of injury! A damaged muffler may cause the per-
missible noise level to be exceeded, presenting a risk
of severe damage to the hearing or hearing loss. Never
operate the machine if the muffler is damaged, miss-
ing or if it has been modified in any way. A damaged
muffler must be replaced.
NOTE
Risk of fire! The hot muffler may cause flammable material
to catch fire. Never place the hot machine on or against
flammable material!
NOTE
The muffler incorporates a catalytic converter, needed in
order to ensure the engine complies with current emis-
sions standards. Never attempt to modify or remove
the catalytic converter: in doing so, you will be break-
ing the law.
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. Splin-
tering 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 hear-
ing loss.
CAUTION
The cutting disc and parts of the machine get hot dur-
ing 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" position.
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 upwards.
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 disengaged,
until the motor starts.
NOTE The motor will flood if the starting procedure
is repeated too many times with the choke engaged.
