Safety regulations
The corresponding safety information can be
found in the enclosed booklet.
Operating instructions for
right-angle grinders
The machine is light, handy, totally insulated and
designed in compliance with the international
specifications CEE 20. Provided it is serviced as
described in these instructions, the machine will
serve you for a long time.
VOLTAGE
Before you use the machine for the first time, check
that the voltage marked on the rating plate is the
same as your mains voltage. Under no
circumstances is the mains voltage to differ from the
rated voltage by more than 10%.
SWITCH (Fig. 1)
The angle grinder comes with a safety switch which
is designed to prevent accidents. To switch on, push
the locking button (1) forward and press the switch
button (2). To switch off, let go of the switch button
(2).
REPLACING THE GRINDING WHEEL
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.
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 flange nut with the flat side facing
the grinding or cutting wheel.
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.
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.
ADDITIONAL HANDLE (FIG. 2)
The angle grinder comes with a special additional
handle that can be adapted to the working position in
question.
To fix the additional handle in position, turn the lock
nut (1) all the way onto the additional handle. Then
screw the additional handle fully onto the angle
grinder. Now adjust the handle to the position
required and fix it in place with the lock nut (1).
Important! The thread of the additional handle has to
be screwed as far as possible into the angle grinder.
CARBON BRUSHES
Carbon brushes that are burned, broken or shorter
than 5 mm are to be replaced by original
replacement brushes. Always replace the carbon
brushes in pairs.
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 11,000 rpm and a
peripheral speed of 80 m/sec.
OPERATING MODES
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.
Cutting:
When you use the right-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 asbestos
materials!
Never use a cutting wheel for rough grinding.
