Selection of the Sanding Plate
Depending on the application, the machine can be equipped
with sanding plates of different hardness:
– Soft sanding plate: Suitable for polishing and sensitive
sanding (also for curved surfaces).
– Medium sanding plate: Suitable for all sanding applications
and general-purpose use.
– Hard sanding plate: Suitable for high sanding capacity on
flat surfaces.
Replacing the Sanding Plate (see figure B)
Note: Replace a damaged sanding plate 8 immediately.
Pull off the sanding sheet or polishing tool. Completely un-
screw the screw 11 and take off the sanding plate 8. Attach
the new sanding plate 8 and tighten the screw again.
Note: When attaching the sanding plate, pay attention that
the toothing of the drive element engage into the openings of
the sanding plate.
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 suita-
ble for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.

Integrated Dust Extraction with Dust Box
(see figures C1 –C4)
Before assembling the dust box 6, pull out the plastic slider
13. Place the dust box 6 onto the extraction outlet 14 and al-
low it to engage. Make sure that the plastic slider 13 engages
in the holder 12.
To empty the dust box 6, press the latching levers 15 on the
side of the dust box (). Pull off the dust box toward the bot-
tom ().
Before opening the dust box 6, it is recommended to loosen
the dust from the filter element by gently striking it against a
firm support (as shown in the figure).
Grasp the dust box 6 by the recessed grip, fold the filter ele-
ment 16 upward and empty the dust box. Clean the thin
plates of the filter element 16 with a soft brush.
External Dust Extraction (see figure D)
Slide the extraction adapter 17 onto the outlet piece 14. En-
sure that the latching levers of the extraction adapter engage.
The extraction adapter 17 accepts a vacuum hose with a di-
ameter of 19 mm.
For removal of the extraction adapter 17, press the latching
levers together at the rear and pull the extraction adapter off.
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.
