– Use dust extraction whenever possible.

ing place.
– It is recommended to wear a P2 filter-

Observe the relevant regulations in your
country for the materials to be worked.
The vacuum cleaner must be approved for the
extraction of masonry dust. Bosch provides suit-
able vacuum cleaners.
The machine can be plugged directly into the re-
ceptacle of a Bosch all-purpose vacuum cleaner
with remote starting control. The vacuum clean-
er starts automatically when the machine is
switched on.
Mount the elbow 11 onto the vacuum connec-
tion 10 and connect a vacuum hose 12 (accesso-
ry). Connect the vacuum hose 12 with a vacuum
cleaner (accessory). An overview for the con-
nection of various vacuum 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 recom-
mended by Bosch. Other combinations can
lead to insufficient dust collection and sepa-
ration.
– Observe the operating instructions of the
vacuum cleaner for maintenance and clean-
ing of the vacuum cleaner, including the fil-
ter. 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 clean-
er.
– Only use vacuum hoses as intended for by
Bosch. Do not manipulate the vacuum hose.
When rocks or chunks of stone/masonry are
drawn into the vacuum hose, cease work and
clean the vacuum hose immediately. Prevent
the vacuum hose from being bent or creased.
– Use the wall chaser only according to its in-
tended use.
– Only use tools that are in perfect condition.
Decrease in work progress is noticeable
whilst using worn tools.
– Observe the general requirements for con-
struction sites.
– Provide for good ventilation.
– Ensure that the working range/area is free of
obstructions. For longer slots, the vacuum
cleaner must be guided along in time, with-
out obstructions in the path.
– Wear hearing protection, protective goggles,
dust mask and gloves as required. As dust
mask, use at least a particle-filtering class
FFP 2 half-mask.
– Use a suitable vacuum cleaner for cleaning
the workplace. Prevent settled dust from be-
ing swirled up by sweeping.
Adjusting the Protection Guard
The protection guard 8 can be adjusted within
limits.
Loosen clamping lever 14 and turn the protec-
tion guard 8 according to the working condi-
tions. Pay attention not to misadjust screw 13.
Afterwards, tighten the protection guard 8 with
clamping lever 14 again.
Mounting the Auxiliary Handle
Depending on the working manner, screw the
auxiliary handle 4 to the right or left on the aux-
iliary-handle holder.
After loosening locking screw 6, the auxiliary-
handle holder can be adapted to the respective
working position in 30° steps.
When tightening locking screw 6, take care that
the four positioning pins on the auxiliary-handle
holder are seated in the holes of the protection
guard 8.
