To switch off, press the switch downwards - this
releases the switch locking and it goes into the
OFF position.
See Fig. 2 for connection and disconnection of the
power cable.
Always switch the machine off before
connecting or disconnecting the mains
lead!
4 Electronics
The machine has full-wave electronics
with the following features:
Smooth start-up
The smooth start-up ensures the machine starts
up jolt-free.
Speed adjustment
You can regulate the speed steplessly between
3000 and 6000 rpm using the adjusting wheel (1.6).
This enables you to optimise the cutting speed to
suit the material.
Constant speed
The pre-selected speed remains constant whether
the machine is in operation or in neutral posi-
tion.
Temperature control
If the motor temperature becomes too high, the
power supply and speed are reduced. The tool
then only runs with reduced power to enable
rapid cooling by means of the motor ventilation.
After cooling down, the tool accelerates again
automatically.
5 Machine settings
Always remove the power supply plug
from the socket before carrying out any
work on the machine.
5.1 Sanding motion
You can use the switch (1.1) to set two different
sanding motions.
The change can only be made when the
sanding pad is stationary, as the switch
is locked in place during operation for
reasons of safety.
Rotex rotary motion (coarse sanding, polish-
ing)
The Rotex rotary motion is a combina-
tion of rotary and eccentric motions. This
position is selected for sanding with high
output (coarse sanding) and polishing.
Slide the switch (1.1) into the right position.
Eccentric motion (fi ne sanding)
This position is selected for sanding with
low output for a scratch-free surface (fi ne
sanding).
Press the switch (1.1) downwards and push it into
the left-hand position.
5.2
Sanding pad brake
The rubber collar (3.1) prevents the sanding pad
from revving up to maximum speed in an un-
controlled manner during eccentric motion (fi ne
sanding). Because the collar wears down in the
course of time, it has to be replaced by a new one
(order no. 453 388) as soon as there is any reduc-
tion in the braking effect.
5.3
Choice and installation of the sanding
disks
Choise of sanding disk
The appliance can be fi tted with three sanding
disks of different hardness depending on the
surface to be treated.
Hard: coarse sanding on surfaces, sanding at
edges.
Soft: universal for coarse and fi ne sanding for fl at
and curved surfaces.
Super-soft: fi ne sanding on formed parts, curves,
radii. Do not use on edges!
Assembly
The FastFix system enables tool-free replacement
of the sanding pad:
- Set the switch (1.1) to the right, to the Rotex
rotary motion
- Press spindle stop (1.5), direction of movement
(3.2) fi rst to the side, then forwards
- Turn the fi tted sanding pad from the spindle
(right-handed thread)
- Keep the spindle stop pressed and screw on the
new sanding pad (in doing so, make sure that
the rubber collar (3.1) is correctly fi tted!)
- let go of the spindle stop
Actuate the spindle stop only when the drive spin-
dle is stationary. Do not switch on the motor when
the spindle stop is pressed in.
5.4
Attaching sanding material
The appropriate Stickfi x sanding paper and Stick-
fi x sanding felt can be fastened quickly and easily
onto the Stickfi x sanding base.
The self-adhesive sanding material is simply
pressed onto the sanding base (1.7) and held
safely in place by the Stickfi x sanding base vel-
cro surface. After use, the StickFix sandpaper is
simply pulled off.
