WARNING: Make sure the DC output leads, terminals, or connector are all in good
working condition.
DO NOT USE THIS CHARGER IF:
The DC output connector, (if equipped) is loose or does not make good contact; Is cracked or
broken; The leads are cut or have exposed wires; The DC output leads or connector feel hot when
used.
Using this charger with any of the above symptoms could result in a fire, property damage, or
personal injury. Have a qualified service person make the necessary repairs. Repairs should not
be made by people who are not qualified.
NORMAL OPERATION:
1.) When conn ecting charge leads directly to the battery, apply grease to the terminals to inh ibit
corrosion.
2.) Plug the charger into AC power having the same ratings as that of the ch arger.
3). The LED on the charger will light, indicating charge current is flowing.
4). The OBET chargers are equipped with a electron ic timer. At the battery gassing threshold,
(2.3 volts per cell) the timer will activate and run for three hours. During this period, the
batteries are in a gassing mode. (2.5 - 2.6 volts per cell max.) After three hours the charger
will shut off. Indicated by an extinguished LED
5). To discontinue charging, unplug the AC power cord. Plugging the AC power back in will
cause the charger to repeat the cycle.
EQUALIZATION:
When using multiple batteries in series, cells become uneven during charge and discharge cycles.
At least once a month perform two charge cycles back to back, this will bring up cells that are
lagging behind full charged cells and is important to overall battery performance.
WARNING: Do not disconnect the DC output leads or unplug the connector from the
batteries when the charger is on. The resulting arcing could cause the
batteries to explode. If the charger must be stopped unplug the AC power.
WARNING: Failure to unplug AC power before moving or driving equipment will result
in damage to cords, plugs and receptacles.
TROUBLE SHOOTING:
CAUTION: DO NOT DISASSEMBLE THE CHARGER. Incorrect assembly may result in
a risk of electric shock or fire. Contact factory.
DANGER: To reduce the risk of electric shock, always disconnect both the AC power
supply cord and the output leads or connector before attempting any
maintenance cleaning.
