7.4 Picking up dry dust
NOTE
Before using the appliance to pick up dry dust,
especially dust from mineral materials, always
check to ensure that the correct dust bag (Hilti
accessory) is fitted in the container. The ma-
terial collected can then be disposed of cleanly
and easily.
CAUTION
The material collected must be disposed of
in accordance with the applicable regula-
tions.
CAUTION
Never use the appliance without a filter ele-
ment.
CAUTION
When fitting the top section of the vacuum
cleaner, take care to avoid pinching your
fingers or damaging the supply cord.
Check to ensure that the filter element is dry.
A damp filter element will quickly become
clogged when dry dust is picked up with the
appliance. Accordingly, before being used for
picking up dry dust, the filter element should
be rinsed and allowed to dry or replaced with
another dry filter element.

fleece
DANGER
Check that the bag has not been pierced
through by objects which may cause injury.
