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. A risk of fire, explosion or injury through con-
tact with caustic substances may otherwise result.
en
d) Do not use batteries other than those approved
for use with the applicable power tool or appli-
ance. Use of other batteries or use of the battery for
purposes for which it is not intended 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.
5.5.5 Work area
a) Ensure that the workplace is well lit.

6 Before use

6.1 Battery use and care
NOTE
Battery performance drops at low temperatures. Never
use the battery until the cells become fully discharged.
Change to the second battery as soon as a drop in per-
formance is noticed. Recharge the battery immediately
so that it is ready for reuse.
Store the battery in a cool, dry place. Never store the
battery where it is exposed to direct sunlight or sources
of heat, e.g. on heaters / radiators or behind a motor
vehicle windscreen. Batteries that have reached the end
of their life must be disposed of safely and correctly to
avoid environmental pollution.
Insert the battery in the corresponding charger.

ing charger. Read the operating instructions for the
charger for further information about the charging
procedure.
6.2.1 Charging a new battery for the first time
A new battery must be charged correctly for the first time
before use. This will ensure that the cells form correctly.
Incorrect initial charging may have a permanent, negative
effect on battery capacity. Please refer to the applicable
battery charger's operating instructions for information
about initial charging.
6.2.2 Recharging NiCd batteries
NiCd batteries should be allowed to reach full charge
each time they are charged.
6.2.3 Recharging Li-ion batteries
CAUTION
Make sure that the outer surfaces of the battery are
clean and dry before inserting it in the charger. Ob-
serve the operating instructions for the charger.
Li-ion batteries are ready for use at any time, even when
only partly charged. Charging progress is indicated by
the LED display (see charger operating instructions).
