The switch [1-3] is an on/off switch (I = ON,
0 = OFF).
The circuit closer can only be actuated if
the change-over switch [1-2] is in an en-
gaged position.
In case of a power failure or if the mains
connector is removed, move the on/off
switch immediately to the Off position.
This prevents uncontrolled restarting.
Consider the pictures on the fold-out page.
WARNING
Risk of injury, electric shock
Always pull the plug out of the socket be-
fore performing any type of work on the
machine!
Electronics
The machine features full-wave electronics
with the following features:
Smooth start-up
The electronically controlled smooth start-up
ensures that the machine starts up jolt-free.
Speed control
You can regulate the speed steplessly with
the adjusting wheel [1-6] in the speed range
(see Technical data). This enables you to op-
timise the cutting speed to suit the surface
(see table).
Constant speed
The preselected motor speed remains con-
stant through electronic control to ensure a
uniform cutting speed even when under load.
Temperature cut-out
The machine power supply is limited and the
speed reduced if the motor exceeds a certain
temperature. The machine continues operat-

If an extension cord is required, it must have
sufficient cross-section to prevent an exces-
sive drop in voltage or overheating. An ex-
cessive drop in voltage reduces the output
and can lead to failure of the motor. The table
below shows you the correct cord diameter
as a function of the cord length for this tool.
Total Extension
Cord Lenght (feet)
Cable size (AWG)
Use only U.L. and CSA listed extension cords.
Never use two extension cords together. In-
stead, use one long one.
The lower the AWG number, the stronger
the cord.

ing at reduced power to allow the ventilator
to cool the motor quickly. If the machine
temperature exceeds the maximum permit-
ted value for longer periods, the machine
switches off completely after approx. 40 sec-
onds and can only be switched on again once
the motor has cooled sufficiently.
Setting sanding motion - Fig. [3]
The change-over switch [1-2] can be used
to set three different sanding motions.
This change-over can only be carried out
with the sanding pad stationary because
the switch is locked during operation.
Coarse sanding, polishing - ROTEX rota-
ry motion
The Rotex rotary motion is a combi-
nation of rotary and eccentric mo-
tions. This position is selected for
sanding with high output (coarse
sanding) and polishing.
