NOTE
Before using the appliance to pick up dry dust,

check to ensure that the correct dust bag (Hilti

CAUTION

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.
