Care and maintenance
8.1
Care and maintenance of the appliance
WARNING
Electrical hazards.
Improper repairs to electrical parts may lead to serious injuries.
▶
Electrical parts may be repaired only by trained electrical specialists.
▶
Keep the appliance, especially its grip surfaces, clean and free from oil and grease. Do not use cleaning
agents containing silicone.
▶
Never operate the vacuum cleaner when the air vents are blocked. Clean the air vents carefully using a
dry brush. Do not permit foreign objects to enter the interior of the appliance.
▶
Clean the outer surfaces of the appliance with a slightly damp cloth at regular intervals. Do not use a
spray system, pressure jet washer or running water for cleaning as this may negatively affect the electrical
safety of the appliance.
The appliance must be handled for cleaning and maintenance in a way that avoids exposing maintenance
personnel and other persons to any hazards.
▶
Use filtered forced ventilation.
▶
Wear personal protective equipment.
▶
Clean the maintenance area in a way that prevents hazardous substances escaping into the surrounding
environment.
▶
Vacuum off the outer surfaces of the appliance and wipe it clean or seal it in a suitable container, e.g.
large plastic bag, before removing it from an area contaminated with hazardous substances. This will
help to avoid distribution of the hazardous dust deposited on it.
▶
When maintenance or repairs are carried out, all contaminated parts which cannot be satisfactorily
cleaned must be packed in impermeable bags and disposed of in compliance with the applicable
disposal regulations.
▶
The appliance must be subjected to a technical inspection by
Hilti
Service or a trained person at least
once a year to check, for example, for damage to the filter, air leakage, and to ensure correct operation
of controlling devices.
▶
In addition, the filter efficiency of H-class vacuum cleaners has to be tested at least once a year or
possibly more frequently if so required by country-specific regulations. The procedure for verifying the
filter efficiency of the vacuum cleaner is set out in 22.AA.201.2. If failed, the test has to be repeated with
a new main filter installed.
8.2
Automatic filter cleaning
Do not attempt to clean the filter element by knocking it against a hard object and do not use pointed
instruments. This will reduce the life of the filter element.
Do not use compressed air to clean the filter element. This may cause tears in the filter material.
The condition of the filter element deteriorates with use.
▶
Replace the filter element at least every six months.
▶
However, if used intensively, the filter element should be replaced more often.
8.3
