Declaration Of Conformity - Bosch PSB 650 RE Original Instructions Manual

The vibration emission 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
another. It may be used for a preliminary assessment of expo-
sure.
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 poorly maintained,
the vibration emission may differ. This may significantly in-
crease 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 pe-
riod.
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 650 RA/ PSB 750 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 suita-
ble for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.

Certification
Observe the relevant regulations in your country for the
materials 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 17
mounted, as otherwise dust/chips could access the interi-
or of the power tool and cause damage.
– Check the condition of the filter element 17 regularly. Re-
place a damaged filter element immediately.
– The dust protection ring 19 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 11 from the front toward the bot-
tom side of the impact drill. Pay attention 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 indi-
cator 13 is full, the dust collector 12 must be emptied. For
this, press on the riffled surface of the release button 16 and
take off the dust collector 12.
Empty and clean the dust collector 12. Clean the filter ele-
ment 17 by gently striking or tapping against it.
Check the filter element 17 for damage and replace it as re-
quired.
