6 Operation
6.1 Inserting and charging the battery
CAUTION
This appliance is designed for use with the specified Hilti batteries.
Charging other batteries is not permissible. A risk of personal
injury or fire and irreparable damage to the battery and charger
may otherwise result. A caustic liquid may leak from defective
batteries. Avoid contact with this liquid.
NOTE
Before inserting the battery, check that the contacts are clean and
free from grease.
Push the battery into the interface provided.
Check that the battery and charger interfaces match (keyed fit).
Charging begins automatically after insertion of the battery in the
charger.
NOTE
The battery will suffer no damage even when left in the charger
for long periods. In this case, however, it is necessary that the
charger is operating (green LED on the charger must be lit). After
the battery has been charged, it receives a regular trickle charge
over a period of 48 hours in order to ensure that full battery
capacity is maintained. The battery charge status LED goes out
after 48 hours, even although the battery is fully charged. For
safety reasons, it is recommended that the battery is removed
from the charger after completion of the charging cycle.
6.2 Removing the battery 4
1. Press one or both release buttons.
2. Pull the battery out of the appliance toward the rear.
6.3 Care of the Li-ion battery
Avoid entrance of moisture.
Charge the battery fully before using it for the first time.
In order to achieve maximum battery life, stop discharging the
battery as soon as a significant drop in performance is noticed.
NOTE
If use of the appliance continues, further battery discharge will be
stopped automatically before the battery cells suffer damage.
Charge the battery with the Hilti charger approved for use with
Li-ion batteries.
NOTE
– A conditioning charge (as is required with NiCd or NiMH
batteries) is not necessary.
– Interruption of the charging procedure has no negative effect
on battery life.
– Charging can be started at any time with no negative effect
on battery life. There is no memory effect (as with NiCd or
NiMH batteries).
– For best results, batteries should be stored fully charged in a
cool dry place. Avoid charging the battery in places subject
to high ambient temperatures (e.g. at a window) as this has
an adverse effect on battery life and increases the rate of
self-discharge.
– If the battery no longer reaches full charge, it may have lost
capacity due to aging or overstressing. It is possible to
continue working with a battery in this condition but it should
be replaced in good time.
