Do not make battery connections
in reverse. Doing so will result in
equipment damage.
The 12 VDC receptacle may be used to
recharge 12 VDC automotive batteries only.
The DC charging output is not regulated. The
circuit protector does not prevent over-
charging a battery.
1. Connect the charging cable to the genera-
tor first, then the battery. ALWAYS connect
the red lead to positive (+), and the black
to negative (-).
2. Start generator and use as normal.
Charging time will vary with battery size
and condition. Check voltage at battery
terminals once the charging cable has
been unplugged, or generator has been
shut down.
NOTE: This receptacle cannot recharge 6 Volt
batteries and cannot be used to crank an
engine having a discharged battery.
