Instructions for care of vacuum cleaners
WARNING
Electric shock hazard!
Improper repairs to electrical parts can lead to serious injuries due to electric shock.
▶
Electrical parts may be repaired only by trained electrical specialists.
▶
Keep the vacuum cleaner, 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. Prevent foreign matter from penetrating inside the turbine aperture.
▶
Clean the exterior of the vacuum cleaner with a slightly damp cloth at regular intervals. Do not use a spray
system, pressure jet washer or running water for cleaning as this could negatively affect the electrical
safety of the vacuum cleaner.
▶
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.

Handling of the vacuum cleaner for cleaning and maintenance must be such that maintenance personnel
and others are not endangered.
▶
Use filtered forced ventilation.
▶
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.
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
1. Set the control switch to the
OFF
position.
2. Open the 2 catches.
