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.
