SWITCHING ON - SWITCHING Off
The polisher is secured against unintentional
switching on.
Switching on: Select the necessary speed by ro-
tating the electronic regulator (8). Move the ON/
OFF switch (5) forward.
Switching off: Move the ON/OFF switch (5)
backward.
ELECTRONIC SPEED PRE-SELECTION
The rotation speed can be varied smoothly by
turning the electronic regulator (8), positioned
on the rear of the polisher.
The speed adjustment range varies from n=240

The recommended regulator positions for the
different areas of applications are specified in
the table below:

painted or varnished surfaces with
a sponge or lambswool pad
E - G
The polisher is equipped with full-wave tacho-
constant electronics for:
- Soft start and restriction of the starting cur-
rent;
- Speed pre-selection and adjustment and
maintaining constant rpm upon overloading;
- Overload protection:
A current clutch actuates upon considerable
brief overload to switch the machine off until the
load drops down.
Upon minor continuous overload the thermal
overload protection actuates, to reduce mo-
tor rpm. The machine becomes disabled. To
resume operation after the machine has cooled
down for 2-4 minutes, first turn off and then turn
on the ON/OFF switch;
- Non-self starting safety (NVR) at restoring
the mains supply. To resume operation after
the current clutch has switched the machine off,
release the ON/OFF switch and then press the
switch again.
- Stabilizing the spindle speed.
MOUNTING THE ACCESSORIES
When mounting the polishing accessories fix the
sander spindle (1) by pressing the lock button
(3) positioned on the gear box.
WARNING:
Never press the button
(3) while the spindle (8) is still rotating!
MOUNTING THE fLEXIBLE BACKING
PAD
The precise and accurate performance of the
below described procedures guarantees the
reliable and safe operation with the power tool.
All instructions are important and result from our
huge experience gained during design and op-
eration of power tools for the described use.
The flexible backing pad (7) is mounted onto the
spindle (1) by M14 thread. The flexible backing
pad (7) is equipped with hook-and-loop fasten-
ing to the operating tools.
The machine is delivered with the flexible back
-
ing pad (7) assembled.
Perform the following procedures in case it is
necessary to mount the flexible backing pad (7)
again:
1. Ensure that the power tool is unplugged.
2. Turn the machine in a way ensuring ac
-
cess to the operating tool. We recommend fixing
the machine in stationary position. Thus it would
be possible to use both hands for convenient
and safe assembly.
3. Clean the threaded and face surfaces of
the spindle (1) using soft cloth and brush.
4. Clean the face surface of the support bush
(6) and the flexible backing pad (7) using soft
cloth and brush.
5. Mount the support bush (6) onto the spin-
dle (1).
6. Ensure there is no dirt or foreign body be-
tween the spindle (1) face and the support bush
(6) face which may hamper their contact. The
presence of foreign bodies and disturbed face
contact are prerequisites for inexact movement
of the operating tool and increased vibration
causing unsatisfactory quality of the processed
surface.
7. Take the flexible backing pad (7).
