Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.
Assembly
 Before any work on the machine itself, pull the mains
plug.
Dust Extraction (PSB 850-2 RA/
PSB 1000-2 RCA) (see figures A–F)
 Dust 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 dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining 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 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. Dust can
easily ignite.
 Use the dust/chip extraction only when working con-
crete, brick and brickwork. Wood or plastic chips can
easily lead to clogging.
 WARNING Fire hazard! Do not work metallic 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.
1 609 92A 1NX | (1.8.16)
– Use the extraction device only with the filter element 19
mounted, as otherwise dust/chips could access the interi-
or of the power tool and cause damage.
– Check the condition of the filter element 19 regularly. Re-
place a damaged filter element immediately.
– The dust protection ring 21 can wear, especially when
working with large drill-bit diameters. Replace the dust
protection ring when worn/damaged.
Mounting the Extraction Device (see figure A)
Guide the extraction device 14 from the front toward the bot-
tom side of the impact drill. Pay attention that the extraction
device 14 faces flush against the casing and that it is locked.
Cleaning the Extraction Device (see figures B–D)
The dust collector 15 is sufficient for approx. 20 drillings with
a drilling diameter of 10 mm.
When the extraction force diminishes the dust collector 15
must be emptied. For this, press on the riffled surface of the
release button 18 and take off the dust collector 15.
Empty and clean the dust collector 15. Clean the filter ele-
ment 19 by gently striking or tapping against it.
Check the filter element 19 for damage and replace it as re-
quired.
Press on the holder of the filter element 19 and pull it out. Re-
place the filter element 19 including the holder. When placing
on the holder again, make sure that the rubber gasket 20 is in-
serted.
Reattach the dust collector 15 again and lock it by pressing
against the smooth surface of the release button 18.
Removing the Extraction Device (see figure E)
For disassembly of the extraction device 14, press release
button 22 and pull off the extraction device 14 toward the
front.
Stowing the Extraction Device (see figure F)
For stowing the extraction device 14 in the case, remove the
extraction device 14, slide it together and attach clamp 23.
Attach the locking latch 24 or empty the dust collector 15 be-
fore placing down the extraction device.

Auxiliary Handle

 Operate your machine only with the auxiliary handle
12.
 Before any work, make sure that the wing bolt 13 is
firmly tightened. Loss of control can cause personal inju-
ry.
The auxiliary handle 12 can be set in 8 positions to achieve a
safe and low-fatigue working stance.
Turn the wing bolt for adjustment of the auxiliary handle 13 in
anticlockwise direction and push the auxiliary handle 12 for-
ward until you can pivot it to the desired position. Then pull
the auxiliary handle 12 back again and tighten the wing bolt
13 again in clockwise direction.
