Before any work on the machine itself, pull
the mains plug.
Dust extraction (PSB 650 RA/
PSB 750 RCA) (see figures A
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.
– As far as possible, use a dust extraction
system suitable for the material.
– 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.
Prevent dust accumulation at the work-
place. Dusts can easily ignite.
Use the dust/chip extraction only when
working concrete, brick and brickwork.
Wood or plastic chips can easily lead to clog-
ging.
WARNING Fire hazard! Do not work metal-
lic materials with the extraction device
mounted. Hot metal chips can ignite parts of
the extraction device.

–
To achieve optimum extraction results, please
observe the following notes:
– Pay attention that the extraction device faces
flush against the workpiece or the wall. This
also makes drilling at a right angle easier.
– When using the extraction device, always
work with the maximum speed.
– After reaching the desired drilling depth, pull
the drill bit out of the drill hole first and then
switch off the impact drill.
– Use the extraction device only with the filter
element 17 mounted, as otherwise dust/
chips could access the interior of the power
tool and cause damage.
– Check the condition of the filter element 17
regularly. Replace a damaged filter element
immediately.
– The dust protection ring 19 can wear, espe-
cially when working with large drill-bit diam-
eters. Replace the dust protection ring when
worn/damaged.
Mounting the Extraction Device (see figure A)
Guide the extraction device 11 from the front to-
ward the bottom side of the impact drill. Pay at-
tention that the extraction device 11 faces flush
against the casing and that it is locked.
Cleaning the Extraction Device
(see figures B–D)
The dust collector 12 is sufficient for approx.
10 drillings with a drilling diameter of 10 mm.
