Right (position B) Left-handed users
Top (position C) Using cutting wheels
5.2 Setting the guard (Fig. 3)
Switch off the tool. Pull the power plug.
Adjust the guard (5) to protect your hands so that
the material being ground is directed away from
your body.
The position of the guard (5) can be adjusted to
any specific working conditions. Undo the screw
(a) and turn the cover (5) into the required
position.
Ensure that the guard (5) correctly covers the
gear wheel casing.
Retighten the screw (a).
Ensure that the guard (5) is secure.
Never use the angle grinder without the
guard.
5.3 TEST RUN FOR NEW GRINDING WHEELS
Allow the right-angle grinder to run in idle for at least
1 minute with the grinding or cutting wheel fitted in
place. Vibrating wheels are to be replaced
immediately.
6. Operation
6.1 Switch (Fig. 4)
The angle grinder comes with a safety switch which is
designed to prevent accidents. To start the
equipment, push the ON/OFF switch (3) forwards and
then press the ON/OFF switch (3).
Wait until the machine has reached its top
speed. You can then position the angle grinder
on the workpiece and machine it.
6.2 Changing the grinding wheels (Fig. 5)
Use the face spanner (6) supplied to change the
grinding wheels.
Pull out the power plug.
Simple wheel change by spindle lock:
Press the spindle lock and allow the grinding
wheel to latch in place.
Open the flange nut with the face spanner.

Important!
Only ever press the spindle lock when the motor
and grinding spindle are at a standstill!
You must keep the spindle lock pressed while

For grinding or cutting wheels up to approx. 3 mm
thick, screw on the flange nut with the flat side facing
the grinding or cutting wheel.

6.4 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.
6.5 GRINDING WHEELS
Never use a grinding or cutting wheel bigger than
the specified diameter.
Before using a grinding or cutting wheel, check
its rated speed.
The wheel´s rated speed must be higher than the
idle speed of the right-angle grinder.
Use only grinding and cutting wheels that are
approved for a minimum speed of 6,000 rpm and
a peripheral speed of 80 m/sec.
Check the direction of rotation when you use
diamond cutting wheels. The directional arrow on
the diamond cutting wheel must point in the
direction in which the tool rotates.
6.6 OPERATING MODES
6.6.1 Rough 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.
