The surface of the sanding plate 3 is fitted with Velcro backing
for quick and easy fastening of sanding sheets with Velcro ad-
hesion.
Press the sanding sheet 4 firmly against the bottom side of
the sanding plate 3.
To ensure optimum dust extraction, pay attention that the
punched holes in the sanding sheet match with the holes in
the sanding plate.

Pull off the sanding sheet. Unscrew the four screws 9 com-
pletely and remove the sanding plate 3. Attach the new sand-

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.

Integrated Dust Extraction with Dust Box
(see Fig. A1 – A4)
Attach the dust box 2 onto the extraction outlet 6 until it
latches.
To empty the dust box 2, press the latching levers 7 on the
side of the dust box (). Pull off the dust box toward the bot-
tom ().
Before opening the dust box 2, 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 2 by the recessed grip, fold the filter ele-
ment 8 upward and empty the dust box. Clean the thin plates
of the filter element 8 with a soft brush.
Note: To ensure optimum dust extraction, empty the dust box
2 in good time and clean the filter element 8 at regular inter-
vals.
When working vertical surfaces, hold the power tool in such a
manner that the dust box 2 faces downward.
External Dust Extraction (see figure C)
Slide the extraction adapter 10 onto the outlet piece 6. En-
sure that the latching levers of the extraction adapter engage.
The extraction adapter 10 accepts a vacuum hose with a di-
ameter of 19 mm.
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.
When working vertical surfaces, hold the power tool in such a
manner that the vacuum hose faces downward.
For removal of the extraction adapter 10, press the latching
levers together at the rear and pull the extraction adapter off.
