Replacing the Sanding Sheet (see figure B)
When attaching a new sanding sheet, remove any dust or de-
bris from the sanding plate
5
(e. g. with a brush).
To ensure optimum dust extraction, pay attention that the
punched holes in the sanding sheet match with the holes in
the sanding plate.
The sanding plate
5
is fitted with Velcro backing for quick and
easy fastening of sanding sheets with Velcro adhesion.
Before attaching the sanding sheet
4
, free the Velcro backing
of the sanding plate
5
from any debris by tapping against it in
order to enable optimum adhesion.
Position the sanding sheet
4
flush alongside one edge of the
sanding plate
5
, then lay the sanding sheet onto the sanding
plate and press firmly.
To remove the sanding sheet
4
, grasp it at one of the tips and
pull it off from the sanding plate
5
.
Sanding accessories, such as fleece pads/polishing cloth
pads, are attached to the sanding plate in the same manner.
Selecting the Sanding Sheet
Depending on the material to be worked and the required rate
of material removal, different sanding sheets are available:
For reworking or polishing, especially of metal and stone, use
fleece/polishing cloth pad.
Depending on the desired surface quality of the workpiece,
different fleece types or polishing cloth pads are to be used.
Replacing the Sanding Plate (see figure C)
n

If, e. g., the front tip of the sanding sheet is worn, you can also
remove the complete sanding plate and reattach it turned by
120°.
Specialty Sanding Plates
You can replace the supplied sanding plate
5
with a specialty
sanding plate, which is available as an accessory.
The specialty sanding plate is attached in the same manner as
the one supplied.
Attach and remove the respective sanding sheets in the same
manner as when changing original sanding sheets.
Pad Extender (see figure D)
With the pad extender
9
you can sand surfaces that are diffi-
cult to access, such as sills on windows, cabinets or doors.
Pad Extender, Narrow (see figure E)
With the narrow pad extender
11
you can sand narrow open-
ings, slots and passages.
Pad Extender, Narrow Rounded (see figure F)
The narrow rounded pad extender
12
allows you to sand
curved and hollow areas or surfaces that are curved inward,
such as on furniture, rails or heating radiators.
Operation
Starting Operation
f
Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Switching On and Off
To
start
the machine, push the On/Off switch
1
towards the
front to “
I
”.
To
switch off
the machine, push the On/Off switch
1
towards
the rear to “
0
”.
When not using the power tool, switch it off in order to save
energy.
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the orbital stroke
rate
2
, you can preselect the required orbital stroke rate, even
during operation.
The required stroke rate depends on the material and the
working conditions and can be determined through practical
testing.
Working Advice
f
Wait until the machine has come to a standstill before
placing it down.
The removal capacity during sanding is mainly determined by
the selection of the sanding sheet as well as the preselected
orbital stroke rate.
Only flawless sanding sheets achieve good sanding capacity
and extend the service life of the machine.
Pay attention to apply uniform sanding pressure; this increas-
es the working life of the sanding sheets.
