Maintenance and care
Warning
First remove the mains plug before doing
any job on the vacuum cleaner.
Dust extracting machines are safeguards
for the prevention or elimination of hazards
defined in the regulations of BGV A1.
In order to carry out maintenance work,
–
the user must disassemble, clean and
service the unit, in so far as this is pos-
sible without endangering maintenance
personnel and other persons. Suitable
precautions include decontamination
before the unit is disassembled. Pre-
cautions must be taken for local filtered
forced air ventilation at the place where
the unit is dissassembled, the cleaning
of the maintenance surface and suita-
ble protection of the personnel.
The outside of the unit should be
–
cleaned thoroughly and any harmful
substances removed. Alternatively, a
sealed coating may be applied before
the unit is removed from the danger ar-
ea. All unit parts are to be considered
contaminated when they are removed
from the danger area.
In the framework of maintenance and
–
repair work all contaminated objects
that cannot be cleaned satisfactorily
must be disposed of. Such objects must
be disposed of in impermeable bags in
accordance with the valid provisions for
the disposal of such waste.
During cleaning or repair of the vacuum
–
cleaner after a period of inactivity, one
must expect a friction-sensitive, explo-
sive-containing crust. This crust must
first be removed with moisture.
Warning
Safety equipment for preventing hazards
must be serviced and maintained regularly.
This means that the manufacturer's staff or
persons trained by the manufacturer must
check the equipment for proper functioning
at least once a year, i.e. check for leaks, fil-
ter damage, functioning of the controlling
elements, etc.
No outside help is required for carrying
–
out basic maintenance and cleaning.
The appliance surface and the inside of
–
the container should be cleaned regu-
larly using a damp cloth.

ways use disposal clothing and P2 or high-
er breath-safe masks while carrying out
