are free from foreign objects before inserting
the battery in the power tool. Short circuiting the
battery terminals presents a risk of fire, explosion
and chemical burns.
i) 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).
j) If the battery gets too hot to touch, this may indi-
cate that it is faulty. Place the tool at a location
where there is no risk of causing a fire (at least 3
meters away from flammable materials), where
it can be kept under observation and allowed to
cool. Contact Hilti Service after the battery has
been allowed to cool.
5.2.4 Electrical safety
Before beginning work, check the working area
(e.g. using a metal detector) to ensure that no
concealed electric cables or gas and water pipes
are present. External metal parts of the power tool
may become live, for example, when an electric cable
is damaged accidentally. This presents a serious risk
of electric shock.
5.2.5 Work area
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated.
Exposure to dust at a poorly ventilated workplace
may result in damage to the health.
5.2.6 Personal protective equipment
The user and any other persons in the vicinity must
wear ANSI Z87.1-approved eye protection, a hard
hat, ear protection, protective gloves and breathing
protection while the machine is in use.
6. Before use
6.1 Battery use and care
NOTE
Battery performance drops at low temperatures. Use
the tool only after fully charging the battery. This
ensures that maximum battery capacity is available.
Change to a second battery as soon as a drop in
performance is noticed. Recharge the battery imme-
diately 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.
6.2 Charging the battery
DANGER
Only used the specified Hilti battery packs and Hilti
battery chargers which are listed under "Acces-
sories".
6.2.1 Charging a new battery for the first time
Charge the battery fully before using it for the first
time.
6.2.2 Charging a previously used battery
Ensure that the outer surfaces of the battery are
clean and dry before inserting it in the corresponding
charger.
