6.3 Securing/Releasing the clamping nut
(depending on features)
Securing the clamping nut (11):
The 2 sides of the clamping nut are different. Screw
the clamping nut onto the spindle as follows:
See illustration D on page 2.
- A) For thin grinding discs:
The edge of the clamping nut (11) faces upwards
so that the thin grinding disc can be attached
securely.
B) For thick grinding discs:
The edge of the clamping (11) faces downwards
so that the 2-hole nut can be attached securely to
the spindle.
- Locking the spindle. Turn the clamping nut (11)
clockwise using the 2-hole spanner (12) to secure.
Releasing the clamping nut:
- Lock the spindle (see chapter 6.1). Turn the
clamping nut (11) anticlockwise using the 2-hole
spanner (12) to unscrew.
7. Use
7.1 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 (4) in the direction of the
arrow and press the trigger switch (5).
Switching off: Release the trigger switch (5).
Continuous operation (depending on features)
Switching on: Slide the lock (4) in the direction of the
arrow, press the trigger switch (5) and keep
it pressed. The machine is now switched on.
Now slide the lock (4) in the direction of the
arrow once more to lock the trigger switch (5)
(continuous operation).
Switching off: Press the trigger switch (5) and
release.

7.2 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.
Wire brushing:
Press down the machine evenly.
8. Cleaning
Cleaning the motor: It is possible
that particles deposit inside the
power tool during operation. This impairs the
cooling of the power tool. Conductive build-up can
impair the protective insulation of the power tool and
cause electrical hazards.
The power tool should be cleaned regularly, often
and thoroughly through all front and rear air vents
using a vacuum cleaner or by blowing in dry air.
Prior to this operation, separate the power tool from
the power source and wear protective glasses and
dust mask.
Button (6) for adjusting the handle: Occasionally
blow compressed air through the button (when
pressed, in all 3 main handle positions). Prior to this
operation, separate the power tool from the power
source and wear protective glasses and dust mask.
9. Troubleshooting
- Switching on the machine reduces the voltage
briefly. Unfavourable mains power conditions may
have a detrimental effect on other machines.
Power impedances less than 0.2 ohm should not
cause malfunctions.
Machine with "WE..." in the model designation:
- Overload protection: The electronic signal
display (3) lights up and the load speed
decreases dramatically. The motor temperature
is too high! Run the machine in idling until it cools
down and the electronic signal display switches
off.
- Overload protection: The electronic signal
display (3) lights up and the load speed
decreases slightly. The machine is overloaded.
Work with a reduced load until the electronic
signal display goes out.
- Electronic safety stop: The electronic signal
display (3) lights up and the machine was
SWITCHED OFF automatically. If the slew rate
