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.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Integrated Dust Extraction with Dust Box
(see Fig. A1 – A4)
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 B)
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.
Replacing the Sanding Sheet
When attaching a new sanding sheet, remove any dust or de-
bris from the sanding plate 9 (e. g. with a brush).
To ensure optimum dust extraction, pay attention that the
punched holes in the sanding sheet match with the holes in
the sanding plate.
Sanding Sheets with Velcro Backing (see figure C)
The sanding plate 9 is fitted with Velcro backing for quick and
easy fastening of sanding sheets with Velcro adhesion.
Before attaching the sanding sheet 19, free the Velcro back-
ing of the sanding plate 9 from any debris by tapping against
it in order to enable optimum adhesion.
2 609 932 910 | (2.12.13)
Position the sanding sheet 19 flush alongside one edge of the
sanding plate 9, then lay the sanding sheet onto the sanding
plate and press firmly.
To remove the sanding sheet 19, grasp it at one of the tips and
pull it off from the sanding plate 9.
Sanding Sheets without Velcro Backing (see figure D)
Lightly lift and unlatch the sanding-sheet clamp 8.
Guide the sanding sheet 19 under the opened rear clamping
bracket 10 to the stop and clamp the sanding sheet by rein-
serting the sanding-sheet clamp 8.
Fold the sanding sheet 19 firmly around the sanding plate.
Guide the other end of the sanding sheet 19 under the open
front clamping bracket 10 and clamp the sanding sheet by re-
inserting the sanding-sheet clamp 8.
Sanding sheets without holes, e. g. from rolls or by the meter,
can be punctured with the perforating tool 20 for use with
dust extraction. For this, press the machine with the mounted
sanding sheet onto the perforating tool (see figure E).
To remove the sanding sheet 19, unlatch the sanding-sheet
clamp 8 and pull out the sanding sheet.
Selecting the Sanding Sheet
Depending on the material to be worked and the required rate
of material removal, different sanding sheets are available:
For the working of all wooden
materials
For coarse-sanding, e. g. of
rough, unplaned beams and
boards
For face sanding and planing
small irregularities
For finish and fine sanding of
hard woods
For the working of paint/
enamel coats or primers and
fillers
For sanding off paint
For sanding primer
For final sanding of primers
before coating
Replacing the Sanding Plate (see figure F)
The sanding plate 9 can be replaced, if required.
Unscrew the 6 screws 21 completely and remove the sanding
plate 9. Attach the new sanding plate 9 and tighten the screws
again.
