Instructions for care of vacuum cleaners for dusts that are hazardous to health
DANGER
Risk of injury by exposure to 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 60 335-2-69 (22.AA.201.2). If
failed, the test has to be repeated with a new main filter installed.
7.2
Filter cleaning
The condition of the filter element deteriorates with use.
Do not clean the filter element by knocking it against hard surfaces. Avoid compressed-air cleaners
and pointed objects that can damage the filter material. By complying with these precautions you
prolong the usable life of the filter element.
▶ Replace the filter element at least every six months.
▶ Replace the filter element more frequently if the appliance is used intensively.
7.3
Changing the filter element
1. Set the control switch to the OFF position.
2. Open the 2 catches.
3. Lift the suction head off the waste material container, turn the suction head upside down and lay it aside.
4. Turn the filter latches through 180 °.
5. Remove the filter frame with filter.
▶ Make sure that no foreign matter drops into the turbine aperture!
6. Remove all dust from the seal and from the filter frame holder.
7. Set the filter frame on a new filter.
8. Fit the filter frame complete with filter into the holder for the filter frame.
9. Lock the filter frame into position with the filter latches.
10. Fit the suction head on to the waste material container and close the two catches.
11. If applicable, remove dust that has dropped from the filter element or the vacuum cleaner.
