Selecting the Sanding Sheet
Depending on the material to be worked and the required rate of material removal, different sanding sheets are available:
Sanding disc Material
– All wooden materials
(e.g., hardwood, soft-
wood, chipboard, build-
ing board)
– Metal materials
– Paint
– Varnish
– Filling compound
– Filler
Dust/Chip Extraction
Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Connecting the Dust Extraction (see figure A)
For sanding, always connect dust extraction.
Remove the application tool/accessory when mounting the
dust extraction 18 (accessory).
If required, assemble the parts of the dust extraction 18 as
shown in the figure. Position the assembled dust extraction
onto the machine via the tool holder 4. Turn the dust extrac-
tion in such a manner that the cams of the dust extraction en-
gage into the corresponding recesses on the housing. Fasten
the dust extraction to the machine with the retaining clip 16
as shown in the figure.
Pay attention that the felt ring 15 is undamaged and faces
tightly against the sanding plate 10. Replace a damage felt
ring immediately.

Application
For coarse-sanding, e.g. of rough, unplaned beams and
boards
For face sanding and planing small irregularities
For finish and fine sanding of wood
For sanding off paint
For sanding primer (e.g., for removing brush dashes, drops
of paint and paint run)
For final sanding of primers before coating
Depending on the machine model, place a vacuum hose 19 (ac-
cessory) either directly onto the vacuum connection 17 or cut
off the old hose end, screw the extraction adapter 20 (accesso-
ry) onto the hose end and insert it directly into the vacuum con-
nection 17. Connect the vacuum hose 19 with a vacuum clean-
er (accessory). An overview for the connection of various
vacuum cleaners can be found at the end of these instructions.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Operation
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.
Starting Operation
Switching On and Off
To start the machine, push the On/Off switch 1 forward so
that the "I" is indicated on the switch.
To switch off the machine, push the On/Off switch 1 toward
the rear so that the "0" is indicated on the switch.
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.
