The vibration level given in this information sheet has been
measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working
period.
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.

plug.
Dust Extraction (PSB 850-2 RA/
PSB 1000-2 RCA) (see figures A–F)
 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 reactions 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 connection with wood-treat-
ment 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 working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the mate-
rials to be worked.
 Prevent dust accumulation at the workplace. Dusts 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.
– 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.
