toolbox). This could cause damage (such as
cracks) to the grinding/cutting wheels and
place the user in serious danger.
7.6 Operating Modes
Securely support the workpiece. Use
clamps or a vice or other proper supports
to grip the workpiece firmly. This is much
safer than holding it in your hand.
7.6.1 Rough grinding (Fig. 11)
Caution: Use the safety device for
grinding.
For the best rough grinding results, hold the
grinding wheel at an angle of between 30°
and 40° to the workpiece surface and guide
back and forth over the workpiece in steady
movements.
7.6.2 Cutting (Fig. 12)
Caution: Use the safety device for
abrasive cutting.
When you use the angle grinder for cutting
purposes, avoid tilting it in the cutting plane.
The cutting wheel must have a clean cutting
edge.
A diamond cutting wheel is best used to cut
hard stone.
It is prohibited to use the machine on

7.4 Motor
It is vital for the motor to be well ventilated
during operation. Be sure, therefore, to keep
the ventilation holes clean at all times.
Never use a grinding or cutting wheel
bigger than the specified diameter.
Before using a grinding or cutting wheel,
check its rated speed.
The maximum speed of the grinding or
cutting wheel used must be higher than
the idle speed of the angle grinder.
Use only grinding and cutting wheels that
are approved for a minimum speed of

and a peripheral speed of
80 m/sec.
Check the direction of rotation when you
use diamond cutting wheels. The direct-
ional arrow on the diamond cutting wheel
must point in the direction in which the
tool rotates.
Take special care that the grinding/cutting
wheels are properly stored and transported.
Ensure that the grinding/cutting wheels are
never exposed to shock, jolts or sharp edges
(for example during transport or storage in a
asbestos materials!
Never use a cutting wheel for rough
grinding.
8. Replacing the power cable
