Never use the angle grinder without the gu-
ard.
6.3 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
fi
tted in place. Vibrating wheels are to be replaced
immediately.
7. Operation
7.1 Switch (Fig. 4)
The angle grinder comes with a safety switch
which is designed to prevent accidents. To switch
on, push the slide switch (a) to the right while at
the same time pushing the ON/OFF switch (2)
forwards and depressing. To switch o
ff
the angle
grinder, depress the button (2) at the back. The
switch (2) will jump back into its starting position.
•
Wait until the machine has reached its top
speed. You can then position the angle grin-
der on the workpiece and machine it.
7.2 Changing the grinding wheels (Fig. 5)
Use the face spanner (5) 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.
•
(Fig. 5)
•
Change the grinding or cutting wheel and
tighten 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 you
change the wheel!
For grinding or cutting wheels up to approx. 3 mm
thick, screw on the
fl
ange nut with the
fl
at side
facing the grinding or cutting wheel.

7.4 MOTOR
It is vital for the motor to be well ventilated during
operation. Be sure, therefore, to keep the ventilati-
on holes clean at all times.
7.5 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 11000 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.
Take special care that the grinding/sanding
wheels are properly stored and transported.
Ensure that the grinding/sanding wheels are
never exposed to shock, jolts or sharp edges (for
example during transport or storage in a toolbox).
This could cause damage (such as cracks) to the
grinding/sanding wheels and place the user in
serious danger.
7.6 OPERATING MODES
7.6.1 Rough grinding
m Caution: Use the safety device for sanding/grin-
ding (included in items supplied).
For the best rough grinding results, hold the grin-
ding wheel at an angle of between 30° and 40° to
the workpiece surface and guide back and forth
over the workpiece in steady movements.
