4. Important information and
precautions
4.1 Use
The BA� 2�1 is a battery starter for cars, trucks,
construction and agricultural machinery with a 12 Volt
vehicle elec-trical system.
The BAT 251 does not require a mains supply.The
starting voltage is free from peaks and guarantees data
protection in the vehicle electrical system. At 12 Volt
the maximum starting current is 1400 Ampere. This is
sufficient to start any engine, even at low temperatures.
4.2 Important instructions for using the
BA� 2�1
R
The BAT 251 must only be used to start vehicles with
a 12 Volt vehicle electrical system.
R
Before using the BAT 251, please read the operating
instructions carefully.
R
Always stand the BAT 251 in an upright position on a
firm base.
R
Connect the terminal clips securely to the vehicle bat-
tery terminals, ensuring correct polarity.
R
Ensure that the BAT 251 is switched off before releas-
ing the terminal clips from the vehicle battery.
R
Each time it is switched on, the BAT 251 checks the
status of its internal battery. The charge status of
the internal battery is displayed for 10 s by means of
LEDs (Fig. 3, Pos. 3, 4 or 5).
R
Every time the BAT 251 is activated, the terminal pli-
ers connection is evaluated and the result displayed
by LEDs 6 - 8 (see ch. 4.4). Therefore, always connect
the terminal pliers before activating BAT 251 . No
evaluation is performed during operation except if the
terminal pliers are disconnected from the battery.
R
The BAT 251 recognizes the end of the start-up proc-
ess. If the engine starts, the BAT 251 switches off
automatically.
R
In "battery replacement mode" there is no safety
monitoring. Ensure correct polarity.
R
For safety reasons, only trained personnel who are
familiar with its operation may use the battery starter.
R
Exercise caution when opening the BAT 251. The bat-
tery is charged. Risk of short-circuit at the terminals.
Always use insulated tools.
R
To avoid a damaging exhaustive discharge of the
internal battery, the ON period for the BAT 251 is
restricted to 4 h in all operating modes. The voltage
of the internal battery is continuously monitored
according to the operating mode. The BAT 251 shuts
down if a critical limit is violated.
