Noise/Vibration Information
Measured values determined according to EN 60745 (lime-sand brick).
Typically the A-weighted noise levels of the product are
Sound pressure level
Sound power level

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.

Dust Extraction
 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
materials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
The vacuum cleaner must be approved for the extraction of
masonry dust. Bosch provides suitable vacuum cleaners.
The machine can be plugged directly into the receptacle of a
Bosch all-purpose vacuum cleaner with remote starting con-
trol. The vacuum cleaner starts automatically when the ma-
chine is switched on.
Place a vacuum hose 12 (accessory) onto the vacuum connec-
tion 13. Connect the vacuum hose 12 with a vacuum cleaner
(accessory). An overview for the connection of various vacu-
um cleaners can be found at the end of these instructions.
Information for the Use of Wall Chasers
Please observe the following notes in order to reduce the dust
emissions occurring while working.
– Use only the combinations of wall chaser and dust-
category M vacuum cleaner recommended by Bosch. Oth-
er combinations can lead to insufficient dust collection and
separation.
– Observe the operating instructions of the vacuum cleaner
for maintenance and cleaning of the vacuum cleaner, in-
cluding the filter. Empty dust collection containers imme-
diately once full. Clean the filters of the vacuum cleaner
regularly and always insert the filters completely into the
vacuum cleaner.
