Dust/Chip Extraction

Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing 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)
Mount the extraction adapter 9 onto the extrac-
tion outlet 10. Mount the dust box 7 onto the ex-
traction adapter 9, ensuring that it engages.
To empty the dust box 7, press the latching le-
vers 11 on the side of the dust box. Pull off the
dust box.
Bosch Power Tools
Before opening the dust box 7, 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).
Grasp the dust box 7 by the recessed grip, fold
the filter element 12 upward and empty the dust
box. Clean the thin plates of the filter element
12 with a soft brush.
External Dust Extraction
Insert a vacuum hose onto the extraction outlet
10. Connect the vacuum hose to a vacuum
cleaner. See the overview for connecting to var-
ious vacuum cleaners at the end of these oper-
ating instructions.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
Changing the Sanding Belt
(see figure B)
– Completely pivot out the clamping lever 3.
The sanding belt 2 is now loose and can be
removed.
– Mount the new sanding belt 2. Pay attention
that the direction of the arrows on the inside
of the sanding belt correspond with the ar-
row direction on the machine housing.
– Pivot the clamping lever 3 back to its initial
position.
– Pick up the power tool and switch it on. Ad-
just the belt run with adjustment knob 13 un-
til the edge of the sanding belt runs flush
with the guide plate .
Pay attention that the sanding belt 2 does not
move excessively and make contact with the
housing. Check the belt run regularly and read-
just with the adjusment knob 13.
