– Place the workpiece against the angle stop 7.
– Slide the clamping spindle 8 against the workpiece and
firmly clamp the workpiece with the spindle handle 10.
Loosening the Workpiece
– Loosen the spindle handle 10.
– Tilt up the quick release 9 and pull the clamping spindle 8
away from the workpiece.

Starting Operation

 Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate of
the machine.
 Check the cutting disc before using. The cutting disc
must be properly mounted and must rotate freely. Car-
ry 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 coatings, minerals
and metal can be harmful to one's health. Contact with or in-
haling the dusts can trigger allergic reactions to the operator
or bystanders and/or lead to respiratory infections.
Certain metal dusts are considered hazardous, especially in
conjunction with alloys such as zinc, aluminium or chromium.
Materials containing asbestos may only be worked by special-
ists.
– 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 mate-
rials to be worked.
The blade can be blocked by dust, chips or workpiece frag-
ments 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 complete stop.
– Tilt the machine toward the rear, so that small workpiece
fragments can fall out of the opening intended for this pur-
pose.
If required, use a suitable tool to remove all workpiece frag-
ments.
 Prevent dust accumulation at the workplace. 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 save energy, only switch the power tool on when using it.
– 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 becomes very hot while work-
ing.
 Make sure that the spark guard 20 is properly mount-
ed. 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 performance capa-
bility of the machine and shortens the service life of the cut-
ting disc.
Use only cutting discs that are suitable for the material to be
worked.
