Extension Cord

If an extension cord is required, it must have suffi-
cient cross-section to prevent an excessive drop in
voltage or overheating. An excessive 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.
Consider the pictures on the fold-out page.
WARNING
Risk of injury, electric shock
Always pull the mains plug out of the socket be-

fore performing any type of work on the ma-
chine!
Electronics
The machine features full-wave electronics with
the following features:
Smooth start-up
The electronically controlled smooth start-up en-
sures that the machine starts up jolt-free.
Speed control
You can regulate the speed steplessly with the ad-
justing wheel [1-6] in the speed range (see Techni-
cal data). This enables you to optimise the cutting
speed to suit the surface (see table).
Constant speed
The preselected motor speed remains constant
through electronic control to ensure a uniform cut-
ting speed even when under load.
Temperature cut-out
The machine power supply is limited and the speed
reduced if the motor exceeds a certain tempera-
ture. The machine continues operating at reduced
power to allow the ventilator to cool the motor
quickly. If the machine temperature exceeds the

Total Extension Cord
Length (feet)
Cable size (AWG)
Use only U.L. and CSA listed extension cords.
Never use two extension cords together. Instead,
use one long one.
 The lower the AWG number, the stronger the
cord.

maximum permitted value for longer periods, the
machine switches off completely after approx. 40
seconds 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 rotary motion
The Rotex rotary motion is a combination
of rotary and eccentric motions. This po-
sition is selected for sanding with high
output (coarse sanding) and polishing.
Fine sanding - eccentric motion
This position is selected for sanding with
low output for a scratch-free surface
(fine sanding).
