• Use a dry, clean cloth to clean the contacts of the product.
• Keep the vacuum cleaner, especially its gripping 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. Prevent foreign matter
from penetrating inside the turbine aperture.
• Clean the top edge of the waste material container and its groove with particular care, because cleanliness here is decisive for the seal
between waste material container and suction head.
Additional instructions for care of vacuum cleaners for dusts that are hazardous to health
DANGER
Risk of injury by contact with or inhalation of dusts that are hazardous to health! Depending on the dust classification, the vacuum cleaner
might contain dust that is hazardous to health.
▶
Emptying and maintenance, including disposal of the dust collection container, may be carried out only by trained and qualified specialists.
Wear the appropriate protective equipment.
▶
All parts of the machine must be assumed to be contaminated when they are removed from the hazardous zone. Implement suitable means
of preventing the spread of dust.
▶
Never operate the vacuum cleaner without the complete filter system fitted.
• Handling of the vacuum cleaner for cleaning and maintenance must be such that maintenance personnel and others are not endangered.
• Use filtered air extraction (e.g. an air cleaner) that continuously filters the dusts that are hazardous to health out of the room air.
• Wear personal protective equipment.
• Clean the maintenance area in a way that prevents hazardous substances escaping into the surrounding environment.
• Before removing the vacuum cleaner from the area contaminated with hazardous substances, use the vacuum cleaner to vacuum its own
exterior clean, wipe it clean or place the vacuum cleaner in a sealed bag or container. 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 the controls.

• 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 that can be used for verifying the filter efficiency of the machine is set out in EN 60335-2-69
(22.AA.201.2). If failed, the test has to be repeated with a new main filter installed.
