• 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.
