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 reac-
tions 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 con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your coun-
try 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
5 until it latches.
To empty the dust box 2, pull off the dust box
downward.
Before opening the dust box 2, it is recommend-
ed 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 2 firmly, fold the filter element
6 upward and empty the dust box. Clean the thin
plates of the filter element 6 with a soft brush.
External Dust Extraction (see figure B)
Insert a vacuum hose 7 onto the extraction outlet 5.
Connect the vacuum hose 7 to a vacuum cleaner.
See the overview for connecting to various vacuum
cleaners at the end of these operating instructions.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special
vacuum cleaner.

Replacing the Sanding Sheet
(see figure C)
When attaching a new sanding sheet, remove any
dust or debris from the sanding plate 3 (e. g. with
a brush).
To ensure optimum dust extraction, pay atten-
tion that the punched holes in the sanding sheet
match with the holes in the sanding plate.
The sanding plate 3 is fitted with Velcro backing
for quick and easy fastening of sanding sheets
with Velcro adhesion.
Before attaching the sanding sheet 4, free the
Velcro backing of the sanding plate 3 from any
debris by tapping against it in order to enable op-
timum adhesion.
The machine is fitted with 2 sanding sheets that
can be changed individually, depending on the
degree of wear.
Only use the machine when both sanding
sheets are mounted.
Only use sanding sheets with the same grain
size.
Position the sanding sheet 4 flush alongside one
edge of the sanding plate 3, then lay the sanding
sheet onto the sanding plate and press it against
it with a light turning motion in clockwise direc-
tion.
To remove the sanding sheet 4, grasp it at one of
the tips and pull it off from the sanding plate 3.
Sanding sheets of the Bosch Delta Sander can be
used.
Sanding accessories, such as fleece pads/polish-
ing cloth pads, are attached to the sanding plate
in the same manner.
