WARNING: Batteries produce explosive gasses, provide adequate ventilation. Extinguish
all open flames and remove all flamables from the area
1). Be sure switch is in the OFF position, and rate control is turned all the way down. Plug
charger into 117 volt AC outlet. flip the power switch to HI if charging from 5-10 12 volt
batteries (30-60 cells) or LO if charging 1-4 12 volt batteries (6-24 cells). DO NOT charge
fewer than (5) 12 volt batteries (30 cells) in the HI position. Overheating to charger will
result.
2). Slowly increase rate control knob until the desired charge current is reached.
3). Continually monitor the line during the charging cycle. Remove any battery that gases’s
excessively. But only after decreasing the rate control to zero, flipping the AC power off, and
unplugging from the source.
Depending on the condition, the size of the batteries, and charge rate, it will take anywhere from
12-36 hours to achieve a specific gravity reading of 1.250 to 1.285 and a voltage reading of
between 14-15 volts per battery while on charge. This indicates batteries are fully charged.
NOTE: the number of batteries online does not influence the charge time.
SHUT DOWN CHARGER:
WARNING: Do not disconnect the charger clamps or move any jumper lead with the
power switch on. The resulting arcing could cause the batteries to explode.
1). Turn rate control all the way down.
2). Flip power switch off.
3). Unplug charger.
4). Disconnect black charge lead, then red.
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.
1). “AC POWER” LED WILL NOT COME ON WHEN POWER SWITCH IS ON
Check that you are plugged into a live circuit. Check AC cord, plug and receptacle for
damage. Check circuit breaker on charger. If the button os popped out, push in to reset.
3). CIRCUIT BREAKER POPS CONTINUALLY
The charger may be shorted internally
4). NO POWER IS PRESENT ACROSS THE DC LEADS WHEN A VOLT METER IS
CONNECTED
Good. The charger will not turn on until the clamps are connected to the battery.
5). THE AC POWER LED COMES ON, BUT NO CURRENT REGISTERS ON THE
