Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Check the cutting disc before using. The
cutting disc must be properly mounted and
must rotate freely. Carry out a 30 second
(min.) test run with no load. Do not use
damaged, out-of-centre or vibrating cutting
discs. Damaged cutting discs can burst and
cause injuries.
Dusts from materials such lead-containing coat-
ings, minerals and metal can be harmful to one's
health. Contact with or inhaling the dusts can
trigger allergic reactions to the operator or by-
standers and/or lead to respiratory infections.
Certain metal dusts are considered hazardous,
especially in conjunction with alloys such as
zinc, aluminium or chromium. Materials contain-
ing asbestos may only be worked by specialists.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your country
for the materials to be worked.
The blade can be blocked by dust, chips or
workpiece fragments in the slot of the base
plate 12.
– Switch the machine off and pull the mains
plug from the socket outlet.
– Wait until the cutting disc has come to a com-
plete stop.
– Tilt the machine toward the rear, so that
small workpiece fragments can fall out of the
opening intended for this purpose.
If required, use a suitable tool to remove all
workpiece fragments.
Prevent dust accumulation at the work-
place. Dusts can easily ignite.

Position of the Operator (see figure F)
Do not stand in a line with the cutting disc
in front of the machine. Always stand aside
of the cutting disc. This measure provides
for better protection of your body against
possible splinters in case of cutting disc
breakage.
Switching On and Off (see figure G)
– To start the machine, firstly press the lock-
off button 1.
Then press the On/Off switch 2 and keep it
pressed.
Note: For safety reasons, the On/Off switch 2
cannot be locked; it must remain pressed during
the entire operation.
– To switch off the machine, release the
On/Off switch 2.
Soft starting
The electronic soft starting feature limits the
torque upon switching on and increases the
working life of the motor.

Working Advice

General Cutting Instructions
Do not touch the cutting disc after working
before it has cooled. The cutting disc be-
comes very hot while working.
Make sure that the spark guard 20 is prop-
erly mounted. Sparking occurs when cutting
metal.
Protect the cutting disc against impact, shock
and grease. Do not subject the cutting disc to
lateral pressure.
Do not strain the power tool so heavily that it
comes to a standstill.
Excessive feed considerably reduces the per-
formance capability of the machine and short-
ens the service life of the cutting disc.
Use only cutting discs that are suitable for the
material to be worked.
