Maintenance and cleaning

DANGER !
IMPORTANT: the precautions described below must
be taken during all the maintenance operations,
including cleaning and replacing of the filter.
a) To allow the user to carry out the maintenance
operations, the vacuum cleaner must be
disassembled, cleaned and overhauled as far as is
reasonably possible, without causing hazards for
the maintenance staff or other people.
IMPORTANT: compartments that are not dust-tight
must be opened with suitable tools (screwdrivers,
wrenches, etc.) and thoroughly cleaned.
b) Carry out a technical inspection at least once a
year, e.g.: check the filter to find out whether the air-
tightness of the vacuum cleaner has been impaired
in any way and make sure that the electric control
panel operates correctly.
This inspection must be carried out by the
manufacturer or by a competent person.
DANGER !
Use only genuine spare parts supplied and authorized
by the manufacturer.

Primary filter disassembly and replacement

DANGER !
Filter replacement is a serious matter.
The filter must be replaced with one of identical filtering
surface characteristics.
Otherwise, the vacuum cleaner will not operate correctly.
