Connect the machine to the mains power sup-
ply.
Before switching on, hold the sanding head
a slight distance away from the working sur-
face.
Switch on the machine.
The on/off switch has a zero voltage actuator,
which prevents the machine from starting auto-
matically after the power supply is interrupted
(e.g. after a power failure). After an interrup-
tion in voltage, press the on/off switch [1-4] to
switch the machine on again.
Perform the necessary sanding work.
Do not overload the machine by pressing with
excessive force! The best sanding results are
achieved with moderate press-on pressure.
The sanding performance and quality are
mainly dependent on the selection of the cor-
rect abrasive.
Switch the machine off once the sanding task
is complete.
Visual warning signals on the sanding head
The following visual signals appear on the LED
[9-2] on the motor housing and the machine de-
creases in speed if necessary.
LED fl ashing slowly
The machine is overheating due to heavy dirt
deposits around the air vent slits and the dust
fi lter [9-1].
Clean the air vent slits.
Remove the dust fi lter [9-1].
Remove the dirt deposits.
Insert the dust fi lter [9-1] until it audibly en-
9-2
gages.
The LED stops fl ashing once the machine is
cleaned and cools down. You can then continue
with your work.
If the LED is still fl ashing after the fi lter sieve and
air vent slits have been cleaned:
Apply less pressure on the surface.
Reduce the suction output with the handwheel
[1-5].
LED fl ashing quickly
If a malfunction occurs and the speed signal is
transferred incorrectly from the handle to the mo-
tor, the motor increases to maximum speed when
switched on and the LED [9-2] fl ashes quickly until
the machine is switched off.
