Before Use; Charging The Battery - Hilti TE 7-A Manual De Instrucciones

5.3.4 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.
5.3.5 Work area safety
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Ex-
posure to dust at a poorly ventilated workplace may
result in damage to the health.
c) There is a risk of injury when the drill bit breaks
through the object in which the hole is being drilled.
Implement the appropriate safety measures at the
rear of the object. Parts breaking away could fall out
and / or fall down and injure other persons.

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.

6.2 Charging the battery

CAUTION
Use only the Hilti chargers listed under "Accessories".
DANGER
Ensure that the outer surfaces of the battery are clean
and dry before inserting it in the corresponding charger.
5.3.6 Personal protective equipment
The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear protec-
tion, protective gloves and breathing protection while
the tool is in use.
5.4 Safety in conjunction with the belt adapter
(accessory)
a) Check that the belt adaptor is securely attached
to the belt before beginning work.
b) Take care to ensure that the cord hanging from
the belt adaptor does not catch on anything. Dis-
connect the power tool from the belt adaptor
before laying it down.
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
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).
6.3 Fitting the battery 2
CAUTION
Before fitting the battery, check that the power tool is
switched off and that the safety lock is engaged (for-
ward/reverse switch in the middle position). Use only the
Hilti batteries intended for use with this power tool.
