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
Red quality
– Paint
– Varnish
– Filling compound
– Filler
White quality
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)
The dust extraction 16 is intended only when working with the
sanding plate 9; it is not of use in combination with other ap-
plication tools.
For sanding, always connect the dust extraction.
To mount the dust extraction 16 (accessory), remove the ap-
plication tool and the depth stop 11.
Slide the dust extraction 16 over and beyond the tool holder
5 to the stop onto the gear head of the power tool. Insert fas-
tening screw 15 into the corresponding recess on the hous-
ing. To lock the screw, turn it to the
Pay attention that the felt ring 17 is undamaged and faces
tightly against the sanding plate 9. Replace a damage felt ring
immediately.
Place a vacuum hose 13 (accessory) onto the vacuum con-
nection 14. Connect the vacuum hose 13 with a vacuum
cleaner (accessory).

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
An overview for connecting to various vacuum cleaners can be
found on the graphics page.
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.
To remove the dust extraction 16, turn fastening screw 15 to
the
head of the power tool.
Operation
Starting Operation
 Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate of
the machine.
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.
To save energy, only switch the power tool on when using it.
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
position.
working conditions and can be determined through practical
testing.
When sawing, cutting and sanding harder materials, e.g.,
wood or metal, it is recommended to work with orbital stroke
rate "6"; for softer materials, such as plastic, orbital stroke
rate "4" is recommended.
