Replacing the Sanding Sheet (see figure A)
To remove the sanding sheet 6, lift it from the side and pull it
off of the sanding plate 5.
When attaching a new sanding sheet, remove any dust or de-
bris from the sanding plate 5, e. g., with a brush.
The surface of the sanding plate 5 is fitted with Velcro backing
for quick and easy fastening of sanding sheets with Velcro ad-
hesion.
Press the sanding sheet 6 firmly against the bottom side of
the sanding plate 5.
To ensure optimum dust extraction, pay attention that the
punched holes in the sanding sheet match with the holes in
the sanding plate.
For easy adjustment of the sanding sheet 6 to the sanding
plate 5, use the adjustment aid in the tool case as shown in the
following figure. Place the sanding sheet into the adjustment
aid with the Velcro facing upward and firmly push on the ma-
chine with 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 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 mate-
rials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Integrated Dust Extraction with Dust Box
(see figures C1–C4)
Attach the dust box 3 onto the extraction outlet 8 until it latch-
es.
The filling level of the dust box 3 can easily be checked
through the transparent container.
To empty the dust box 3, pull it off downward with a light
twisting motion.
Before opening the dust box 3, it is recommended to loosen
the dust from the filter element by gently striking it against a
firm support (as shown in the figure).
Hold the dust box 3 firmly, fold the filter element 9 upward
and empty the dust box. Clean the thin plates of the filter ele-
ment 9 with a soft brush.
