electrical system.
!
In order to avoid any excessive build up of
gas, you should only conduct the charging
process with the switch set to „hot battery"
at ambient temperatures > 15 °C and for
older batteries. If charging is conducted with
the switch set to „cold battery" however, the
charging process must be stopped immedia-
tely the battery is fully charged..
Adhere to the following procedure when
charging batteries:
1. Switch the battery charger off (Fig. 2,
Pos. 9).
2. Unscrew the cell plugs on standard batte-
ries before starting the charging process.
3. Connect the crocodile clip-on terminals
to the proper battery terminals (Fig. 1,
Pos. 1). The red-colored clip goes to the
positive terminal (+) and the blue one to
the negative terminal (-).
4. Set the two-way switch for „cold and hot
batteries" to the correct position (Fig. 2,
Pos. 6). Note that only the battery tempe-
rature is to be evaluated.
5. Turn the potentiometer for setting the
battery charging current (Fig. 2, Pos. 8)
to the left-hand maximum limit (lowest
charging current).
6. Set the two-way switch (Fig. 2, Pos. 5) to
the specified battery nominal voltage for
the battery to be charged.
