Before use

Handling batteries with due care and attention
Note:
– Battery performance drops at low temperatures.
– Never keep on working with the battery until the tool
comes to a stand still. 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 the heat of the sun,
on a radiator, behind a motor vehicle windscreen or
at a window.
– Batteries that have reached the end of their life must
be disposed of safely and correctly to avoid envi-
ronmental pollution.
– Use the Hilti battery only with the approved Hilti
chargers listed in the "Tools and accessories" sec-
tion.
– Ensure that the outer surfaces of the battery are clean
and dry before inserting it in the corresponding
charger.
– Read the operating instructions for the charger for
further information about the charging procedure.
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 per-
manent, negative effect on battery capacity. Please refer
to the applicable battery charger's operating instruc-
tions for information about initial charging.
