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.
5.2.4 Electrical safety
en
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
suitable eye protection, a hard hat, ear protection, protective
gloves and breathing protection while the tool is in use.
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 performance 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.

Use only the Hilti chargers listed under "Insert tools, accessor-
ies".
