en ENGLISH
The contact surfaces of the Autobalancer
support flange (4), grinding wheel and the
Quick-Stop adjusting nut (1) or other adjusting nut
(13) must be clean. Clean if necessary.
- Place the grinding wheel on the Autobalancer
support flange (4). The grinding wheel must lie flat
on the Autobalancer supporting flange.
7.3 Securing/Releasing the "Quick"
clamping nut (depending on features)
Securing the "Quick" clamping nut (1):
Do not use the "Quick" clamping nut if the
accessory has a clamping shank thicker than 8
mm! In this case, use the clamping nut (13) with 2-
hole spanner (14).
Only use the "Quick" clamping nut when
undamaged and in perfect operating
condition: the arrow must point to the notch on the
outer ring (see illustration on page 2).
- Lock the spindle (see chapter 7.1).
- Fit the "Quick" clamping nut (1) on the spindle (3).
See illustration on page 2.
- Tighten the "Quick"clamping nut by turning
clockwise by hand.
- Turn the grinding wheel firmly clockwise to tighten
the "Quick"clamping nut.
For machines with the designation W...B... an
increased resistance is to be felt on the last 180°.
Releasing the clamping nut (1):
- Lock the spindle (see chapter 7.1).
- Turn the "Quick"clamping nut (1) anticlockwise to
unscrew.
7.4 Securing/Releasing the clamping nut
(depending on features)
Securing the clamping nut (13):
The 2 sides of the clamping nut are different. Screw
the clamping nut onto the spindle as follows:
See illustration E on page 2.
- A) For thin grinding discs:
The edge of the clamping nut (13) faces upwards
so that the thin grinding disc can be attached
securely.
B) For thick grinding discs:
The edge of the clamping (13) faces downwards
so that the 2-hole nut can be attached securely to
the spindle.
- Locking the spindle. Turn the clamping nut (13)
clockwise using the 2-hole spanner (14) to secure.
For machines with the designation W...B... an
increased resistance is to be felt on the last 180°.
Releasing the clamping nut:
- Lock the spindle (see chapter 7.1). Turn the
clamping nut (13) anticlockwise using the 2-hole
spanner (14) to unscrew.

8. Use
8.1 Switching On and Off
Always guide the machine with both hands.
Switch on first, then guide the accessory towards the workpiece.
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 using the handles provided, stand
securely and concentrate.
Avoid the machine swirling up or taking in dust
and chips. After switching off the machine,
only place it down when the motor has come to a
standstill.
See illustration A on page 2.
Torque activation
Switching on: Slide the lock (7) in the direction of the
arrow and press the trigger switch (8).
Switching off: Release the trigger switch (8).
Continuous operation (depending on features)
Switching on: Slide the lock (7) in the direction of the
arrow, press the trigger switch (8) and keep
it pressed. The machine is now switched on.
Now slide the lock (7) in the direction of the
arrow once more to lock the trigger switch (8)
(continuous operation).
Switching off: Press the trigger switch (8) and
release.
Machines with the designation W...B:
Torque activation (with dead man's lever)
See illustration B on page 2.
Switching on: Slide the trigger switch (8) forwards
and then push the trigger switch (8)
upwards.
Switching off: Release the trigger switch (8).
8.2 Working Directions
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.
Rough grinding: position the machine at an angle of
30° - 40° for the best working results.
Cutting-off operations:
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.
