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.
