5Beforeuse
5.1 Use the appliance only at a suitable
location.
Use the appliance only indoors.
The location at which the appliance is used
should be clean, dry and cool but protected
from frost.
The appliance must be able to emit heat while in
operation. The ventilation slots must therefore
remain unobstructed.
Accordingly, remove the charger from the tool-
box.
Do not operate the charger inside a closed
container.
5.2 Battery use and care
NOTE
Battery performance drops at low temperat-
ures. Do not continue using the battery un-
til the tool comes to a standstill. Change to
a second battery in good time. 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 or behind glass,
e.g. at a window. Batteries that have reached
theendoftheirlifemustbedisposedofsafely
and correctly to avoid environmental pollution.
5.3 Switching the appliance on
Plug the supply cord into the power outlet.
NOTE
ThegreenLEDlightsaftertheappliancehas
been plugged in. If the green LED doesn’t light
or goes out during operation, unplug the supply
cord from the power outlet and then plug it
in again. If the green LED still doesn’t light
after reconnecting it several times, return the
appliance to Hilti Service for repair.
6 Operation
6.1 Inserting and charging the battery
CAUTION
This appliance is designed for use with the
specified Hilti batteries. Charging other batter-
ies 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.
Check that the battery and charger interfaces
match (keyed fit).
Charging begins automatically after insertion of
the battery in the charger.
NOTE
In case the battery is left in the charger: After
completion of charging, battery voltage is mon-
itored periodically so long as the charger is in
operating mode, i.e. connected to the electric
supply. A new charging cycle is started if the
battery voltage drops below a certain value. If
the charger, with battery inserted, is discon-
nected from the electric supply and then re-
connected, the battery voltage is checked but
the battery will be recharged only if its voltage
is found to be below a certain value. For safety
reasons, however, it is recommended that the
battery is removed from the charger after com-
pletion of a charging.
6.2 Care of the Li-ion battery
Avoid ingress 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 battery performance is noticed.
en
14
Printed: 10.12.2013 | Doc-Nr: PUB / 5069444 / 000 / 01

NOTE
If use continues, further battery discharge will
be stopped automatically before the battery
cells suffer damage.
Charge the battery using an approved charger
from Hilti designed 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. Storing the
battery in places subject to high ambient tem-
peratures (e.g. at a window) 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 over-
stressing. It is still possible to work with this
battery. You should, however, soon replace
the battery with a new one.
