– Tilt up the quick release 15 and pull the clamping spindle
14 away from the workpiece.
Starting Operation
 Observe correct mains voltage! The voltage of the pow-
er 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. 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 9.
– 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 D)
 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.

Working Advice
 Before any work on the machine itself, pull the mains
plug.
General Cutting Instructions
 Do not touch the cutting disc after working before it
has cooled. The cutting disc becomes very hot while work-
ing.
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.
Permissible Workpiece Dimensions
Maximal workpiece sizes:

Minimal workpiece sizes
(= all workpieces that can be clamped via the clamping spin-
dle 14):

Cutting depth, max. (0°/0°): 125 mm
Adjusting the Depth Stop (see figure F)
In the delivery condition of the machine, the depth stop 4 is
adjusted in such a manner that a new 355 mm cutting disc
does not touch the base plate when cutting.
To compensate the wear of the cutting disc, the depth stop
can be set deeper.
