b) Do not expose batteries to high temperatures or
fire. This presents a risk of explosion.
c) Do not disassemble, squash or incinerate batter-
ies and do not subject them to temperatures over
80°C. This presents a risk of fire, explosion or injury
through contact with caustic substances.
d) Use only batteries that are approved for use with
the applicable tool or appliance. Use of unap-
proved batteries or use of the batteries for areas of
application for which they are not approved presents
a risk of fire and explosion.
e) Do not charge or continue to use damaged bat-
teries (e.g. batteries with cracks, broken parts,
bent or pushed-in and/or pulled-out contacts).
f) If the battery gets too hot to touch, this may indicate
that it is faulty. Place the tool in a location where
it can be kept under observation, well away from
flammable materials, and allow it to cool down.
Contact Hilti Service after the battery has been
allowed to cool.
