8.4 Securing/Releasing the clamping nut
(depending on features)
Securing the clamping nut (9):
The 2 sides of the clamping nut are different.
Screw the clamping nut onto the spindle as
follows:
See illustration C on page 3.
- A) For thin grinding wheels:
The edge of the clamping nut (9) faces upwards
so that the thin grinding wheel can be attached
securely.
B) For thick grinding wheels:
The edge of the clamping nut (9) faces down-
wards so that the clamping nut can be attached
securely to the spindle.
- Lock the spindle. Turn the clamping nut (9)
clockwise using the 2-hole spanner (10) to
secure.
Releasing the clamping nut:
- Lock the spindle (see chapter 8.1). Turn the
clamping nut (9) anticlockwise using the 2-hole
spanner (10) to unscrew.

9 Use

9.1 Switching On and Off
Always guide the machine with both hands.
Switch on first, then guide the accessory
towards the workpiece.
The machine must not be allowed to draw in
additional dust and shavings. When
switching the machine on and off, keep it away
from dust deposits. After switching off the
machine, only place it down when the motor has
come to a standstill.
Avoid inadvertent starts: always switch the
tool off when the plug is removed from the
mains socket or if there has been a power cut.
In continuous operation, the machine
continues running if it is forced out of your
hands. Therefore, always hold the machine with
both hands at the intended handles, take a secure
stance and concentrate on the work.
See illustration A on page 3.
Torque activation
Switching on: Slide the lock (5) in the direction of
the arrow and press the trigger (6).
Switching off: Release the trigger (6).
Continuous operation (depending on features)
Switching on: Slide the lock (5) in the direction of
the arrow, press the trigger (6) and keep it
pressed. The machine is now switched on.
Now slide the lock (5) in the direction of the
arrow once more to lock the trigger (6)
(continuous operation).
Switching off: Press the trigger (6) and release.
9.2 Working instructions
Grinding:
Press down the machine evenly on the surface and
move back and forth so that the surface of the
workpiece does not become too hot.
Roughing: position the machine at an angle of 30°
- 40° for the best working results.
Separating:
Always work against the run of the
disc (see illustration). Otherwise
there is the danger of the machine
kicking back from the cut out of
control. Guide the machine evenly at
a speed suitable for the material being processed.
Do not tilt, apply excessive force or sway from side
to side.
Sanding:
Press down the machine evenly on the surface and
move back and forth so that the surface of the
workpiece does not become too hot.
Wire brushing:
Press down the machine evenly.

10 Cleaning

Motor cleaning: blow compressed air through the
rear ventilation slots of the machine regularly,
frequently and thoroughly. Here, the machine must
be held firmly.

11 Troubleshooting

Machine with "X" in the model designation:
- Restart protection: The machine does not
start. The restart protection is active. If the mains
plug is inserted with the machine switched on, or
if the current supply is restored following an
interruption, the machine does not start up.
Switch the machine off and on again.
- When switched on, the machine accelerates
to maximum speed very quickly, i.e. automatic
restriction of the starting current does not work
(soft start). An electronic error exists. Other
safety-related electronic functions are no longer
available. Have the machine repaired immedi-
ately (see 13).
