Connect the machine to the mains power sup- f
ply.
Before switching on, hold the sanding head L
a slight distance away from the working sur-
face.
Switch on the machine. f
The on/off switch has a zero voltage actuator, L
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. f
Do not overload the machine by pressing with L
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 f
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. f
Remove the dust fi lter [9-1]. f
Remove the dirt deposits. f
Insert the dust fi lter [9-1] until it audibly en- f
gages.
The LED stops fl ashing once the machine is L
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. f
Reduce the suction output with the handwheel f
[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.
