● The appliance may be operated, serviced and repaired
only by authorized, trained personnel. This personnel
must be informed of any special hazards that may be
encountered.
● Stay alert.
6. Before use
● The electric supply voltage must comply with the spec-
ification given on the rating plate.
6.1 Operate the charger only at a suitable place
● The charger should be operated only at a dry, clean,
cool place but where it is protected from frost.
● The charger must be able to give off heat during the
charging operation. Accordingly, ensure that the ventilation slots remain unobstructed.
● Accordingly, remove the charger from the toolbox.
● Do not operate the charger inside a closed container.
6.2 Switching on the charger

-NOTE-
All 3 indicator lamps light briefly while the self-test is
being carried out. Subsequently, only the green lamp
should light.
The green lamp blinks if the self-test was unsuccessful.
Should the green lamp continue to blink after the supply cord has been unplugged and then reconnected to
the mains supply, the charger should be returned to a
Hilti service center for repair.
7. Operation
7.1 Inserting the battery
Insert the battery in the appropriate compartment or
interface, depending on the type of Hilti battery to be
charged.
Please use the Hilti CA 7/36 adaptor when charging
BP 40, BP 72, RB 10 and BP 12, batteries (not supplied
with the charger). Ensure that the shape of the battery
terminal section and the adaptor correspond.
The charging procedure starts automatically after the
battery has been fully inserted in the charger.
-NOTE-
The battery will not suffer damage even when left in the
charger for long periods (with the charger in operation).
-CAUTION-
The charger is designed for use with the Hilti batteries
listed. Charging other batteries is not permissible as this
may result in personal injury or serious damage to the
battery.
Corrosive liquids may leak from defective batteries. Avoid
contact with such liquids.
7.2 Indicators
Green lamp lights constantly The charger is connect-
ed to the mains supply
and is ready for use.
blinks A malfunction in the
charger or battery was
detected during the selftest.
Red lamp lights constantly The battery is being
charged.
blinks Battery charging is
complete.

en
Yellow lights constantly The battery is being
lamp charged in refresh mode
(see section 7.3).
blinks The battery is too cold
(< 0°C) or too warm
(> 60°C). Charging does
not start. Charging be gins automatically (incl.
refresh mode, if applicable) as soon as battery
temperature is within
the specified range.
7.3 Refresh mode
The individual cells of a battery are subject to self-discharge. With older batteries, some of the cells may lose
their charge more quickly than others. As conventional
chargers switch off when the first cells have reached full
charge, the other partly-charged cells never receive the
full charge. The user becomes aware of this effect in the
form of inadequate battery capacity.
This effect can be eliminated by charging the battery in
refresh mode.
7.3.1 C 7/24
Start charging in refresh mode by pressing and holding
your finger on the "Refresh” button as the battery is
inserted into the charger. Release the button when the
yellow lamp lights (constantly). The yellow lamp lights
as long as charging in refresh mode is taking place.
The battery should be conditioned by charging in refresh
mode at regular intervals, after approx. every 30–50
stan dard charging cycles, but not more than once a
month, as frequent refreshing may weaken the battery.
Conditioning the battery by charging in refresh mode is,
so to speak, a kind of "training” for the battery. Just as
excessive training can be harmful to the human body,
use of refresh mode too frequently may also weaken the
battery.
7.3.2 C 7/36-ACS
The function described above is controlled automatically
by the C 7/36-ACS charger. Charging in refresh mode
starts automatically, according to battery type, when necessary. When a new battery is charged for the first time,
refresh mode is activated immediately in order to ensure
that the battery cells "form" correctly. If charging in refresh
mode is interrupted, the charger begins charging in
refresh mode when the next charging cycle is started.
-NOTE-
Regular charging in refresh mode ensures maximum
battery performance and long battery life.
The normal charging time may vary (increase) depending on the state of the battery.
7.4 Battery
A new battery must be charged in normal mode (without refresh function) for at least 12–24 hours or charged
once in refresh mode before being used for the first time
in order to ensure that the cells can "form" optimally.
Never use a battery until it becomes fully discharged.
Recharge the battery as soon as its performance drops
noticeably. When a battery is drained until totally discharged, the cells that become discharged first are damaged by the current still being drawn from the other cells.
-NOTE-
● At low temperatures, battery performance drops. Bat-
teries should be stored at room temperature when not
in use.
● At high temperatures, batteries suffer damage. Nev-
er charge or store batteries where they are exposed
to the heat of the sun, e.g. at a window or behind a
motor vehicle windscreen, or on top of a radiator etc.
8. Care and maintenance
Unplug the supply cord from the mains socket.
8.1 Care of the appliance
CAUTION
Always keep the grip surfaces of the appliance free
from oil and grease. Do not use cleaning agents which

a dry brush. Do not permit foreign objects to enter the
interior of the appliance. Clean the outside of the appliance at regular intervals with a slightly damp cloth. Do
not use a spray, steam pressure cleaning equipment or
running water for cleaning. This may negatively affect
the electrical safety of the appliance.
8.2 Maintenance
WARNING
Repairs to electrical parts and replacement of the supply cord may be carried out only by trained electrical
specialists.
