Never operate the appliance when the ventil-

side of the appliance at regular intervals with a
cloth. Do not use a spray, high-pressure water-

Always keep the grip surfaces of the appliance
free from oil and grease. Do not use cleaning
agents which contain silicone.
For vacuum cleaners of the class M, please
note: The appliance must be handled for clean-

Clean the maintenance area in a way that pre-
vents hazardous substances escaping into the
surrounding environment.
Vacuum off the outer surfaces of the appliance,
wipe it clean or seal it in suitable container
or material before removing it from an area

When maintenance or repairs are carried out, all
contaminated parts which cannot be satisfact-
orily cleaned must be packed in impermeable
bags and disposed of in compliance with the
applicable disposal regulations.
A vacuum cleaner of the class M must be sub-

check, for example, for damage to the filter,
air leakage, and to ensure correct operation of
controlling devices.
