Care of the Li­ion batteries
• Never use a battery with clogged air vents. Clean the air vents carefully using a dry, soft brush.
• Avoid unnecessary exposure of the battery to dust and dirt. Never expose the battery to high levels of
moisture (e.g. by being dipped in water or left in the rain).
If a battery has been soaked by moisture, treat it as a damaged battery. Isolate it in a non-flammable
container and consult Hilti Service.
• Keep the battery free of extraneous oil and grease. Do not permit dust or dirt to accumulate unnecessarily
on the battery. Clean the battery with a dry, soft brush or a clean, dry cloth. Do not use cleaning agents
containing silicone as these can attack the plastic parts.
Do not touch the contacts of the battery and do not remove the factory-applied grease from the contacts.
• Use only a slightly damp cloth to clean the housing. Do not use cleaning agents containing silicone as
these can attack the plastic parts.

7.1 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.
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.
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.
