7. Keep the charger and battery pack out of the
reach of children
Knowledgeoftheoperatinginstructions is a must if the
tool is to be used without injury or damage to persons
and / or product respectively.
8. Keep your work area clean and well lit.
9. Keep other persons away from the charger during
the operation.
Before use
Connect the charger to the mains supply.
– The mains voltage must correspond to the infor-
mation given on the rating plate.
ThegreenLEDmustlightconstantly. Ifitdoesnotlight,
proceed as follows:
– Check the mains supply voltage and the connec-
tion of the mains plug to the mains supply.
– Iftheconnectiontothe mains supply or the mains
supplyitselfisnotthe cause of the fault, bring the
charger to a Hilti service centre for repair.
Operate the charger only at a suitable location.
– The location for operation of the charger should
be dry, clean and cool, but not exposed to frost.
– The charger must be able to give off heat during
the charging procedure. Accordingly, the ventila-
tion slots must always be unobstructed.
Wall mount
– The mounting holes provided on the base of the
housing should be used if the charger is to be
mounted in a wall.
– Topreventthebattery pack falling out ofthecharg-
er, the charger must not be mounted on an over-
hanging wall.

Operation
Insert the battery (SFB105, SBP10, SFB125, SBP12,
SFB121,SFB126,SFB150,SFB155,SFB180,SFB185)

Indicators
Green LED
– Lights constantly when the charger is connected to
the mains supply. The charger is ready for opera-
tion.
– When the LED blinks, the battery is not ready to be
charged. (Re-insert the battery. If charging does
not then begin, please refer to the "Care and main-
tenance"sectionoftheSF100-A,SF121-A,SF150-A,
SF180-A or SF4000-A operating instructions.)
Red LED
– Lights constantly: The battery is being charged.
– Blinks: The battery is charged.
Yellow LED
– Lights constantly: The battery is being charged in
conditioning charge mode.
– Blinks: The battery is too cold [approx. 0°C] or too
hot [approx. 60°C]. Charging does not take place.
The charger begins charging automatically as soon
as the battery reaches the required temperature.
Conditioning charge mode
