Make sure the pins on the plug of the extension cord
are the same number, size and shape as the AC
plug of the battery charger. The use of an improper
extension cord could result in a risk of fire or electric
shock. Locate all cords so they will not be stepped
on, tripped over, or otherwise subjected to damage
or stress.
DC OUTPUT
This battery charger is designed to produce a 36 volt
DC output with an initial charge current of 20 amps.
ONLY 36 VOLT, 18 CELL, 168 TO 275 AMP-HOUR,
LIQUID ELECTROLYTE (WET) LEAD-ACID
BATTERIES SHOULD BE USED. The charge
current will decrease gradually to about 6 amps as
the battery reaches full charge and will remain there
until the charger turns off. As the battery ages, the
charge current may no longer decrease to the 6 amp
finish current. Liquid electrolyte batteries will
normally be charged to 2.5-2.6 volts per cell.
OPERATING INSTRUCTIONS
1.
Connect AC supply cord to a properly grounded
120 volt, 60 Hertz, single phase outlet.
2.
Connect the DC output plug by grasping the
plug body and pushing it straight into the
receptacle until it is fully engaged. The BLACK
wire must be connected to battery negative (-),
and the RED or WHITE wire to battery positive
(+). Make sure all connections are clean and
tight.
3.
The charger will start after a short delay as
indicated by the transformer hum and the
ammeter movement.
WARNING: LEAD-ACID BATTERIES
GENERATE GASES WHICH CAN BE EXPLOSIVE.
CHARGE ONLY IN WELL VENTILATED AREAS.
DO NOT DISCONNECT CHARGER DC OUTPUT
TERMINALS FROM BATTERY WHEN CHARGER
IS ON. THE RESULTING ARCING AND BURNING
COULD CAUSE THE BATTERY TO EXPLODE.
KEEP SPARKS, FLAME AND SMOKING
MATERIALS AWAY FROM BATTERY.
If the charger must be stopped, always
disconnect the AC supply cord from its outlet
before disconnecting the DC output terminals
from the battery.
4.
Monitor the ammeter for connect charge current.
The initial charge current should be
approximately 20 amps. If the battery has not
been discharged, or the AC supply voltage is
lower than 120 volts, the initial charge rate may
be less than 20 amps.
5.
Charger turns off automatically when battery is
fully charged. Charge time varies with battery
size and depth of discharge. Allow 8 hours for
normal charging. Severely discharged batteries
may require up to 12 hours to be properly
charged and equalized. After the charger has
turned off, disconnect the DC output plug from
the battery and the AC supply cord from outlet.
MAINTENANCE INSTRUCTIONS
The battery charger requires minimal maintenance.
It should be kept clean and all connections are to be
tightly secured. In the event of intermittent
operation, examine and tighten, if necessary, all
connections. BE SURE THE CHASSIS IS
SECURELY GROUNDED. If any problems cannot
be resolved, consult a qualified service center.
Observe the following battery maintenance
procedures to obtain good performance and
maximum cycle life.
1. Always observe the following personal safety
precautions when working with lead-acid
batteries:
a.
Someone should be within range of your
voice or close enough to come to your aid
when you work near a battery.
b.
Have plenty of fresh water and soap nearby
in case battery acid contacts skin, clothing
or eyes.
c.
Wear complete eye protection and clothing
protection. Avoid touching eyes while
working near battery.
d.
If battery acid contacts skin or clothing,
wash immediately with soap and water. If
acid enters eye, immediately flood eye with
running cold water for at least 10 minutes
and get medical attention.
e.
NEVER smoke or allow a spark or flame in
the vicinity of batteries.
f.
Be extra cautious to reduce risk of dropping
a metal tool onto battery. It might spark or
short-circuit battery or other electrical part
that may cause explosion.
g.
Remove personal metal items such as rings,
bracelets, necklaces, and watches when
working with a lead-acid battery. A lead-
acid battery can produce a short-circuit
current high enough to weld a ring or the like
to metal, causing a severe burn.
h.
NEVER charge a frozen battery.
