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.

6.2 Charging the battery

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

ation about the charging procedure.

charged. Charging progress is indicated by the LED display (see
