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.
– 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.
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.
Bosch Power Tools
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
F)
–
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 16 mounted, as otherwise
dust/chips could access the interior of the
power tool and cause damage.
– Check the condition of the filter element 16
regularly. Replace a damaged filter element
immediately.
– The dust protection ring 18 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.
When the extraction force diminishes or when
the level indicator 13 is full, the dust collector
12 must be emptied. For this, press on the rif-
fled surface of the release button 15 and take
off the dust collector 12.
Empty and clean the dust collector 12. Clean the
filter element 16 by gently striking or tapping
against it.
Check the filter element 16 for damage and re-
place it as required.
Press on the holder of the filter element 16 and
pull it out. Replace the filter element 16 includ-
ing the holder. When placing on the holder
again, make sure that the rubber gasket 17 is in-
serted.
