DC CONNECTION PRECAUTIONS
16.
a.
Connect and disconnect the DC output clamps only after setting the charger switches to the OFF position and removing the AC cord from
the electric outlet. Never allow the clamps to touch each other.
b.
Attach the DC clamps to the battery post and twist or rock back and forth several times to make a good connection. This tends to keep
the clamps from slipping off the terminals and helps to reduce the risk of sparking.
FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN A VEHICLE. A SPARK NEAR THE
17.
BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE
BATTERY:
a.
Position the AC and DC cords to reduce the risk of damage by the hood, door, or moving engine parts.
b.
Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
c.
Check the polarity of the battery post. The POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE (NEG,
N, -) post.
d.
Determine which post of the battery is grounded (connected) to the chassis. If the negative post is grounded to the chassis (as in most
vehicles), see item "e". If the positive post is grounded to the chassis, see item "f".
e.
For negative-grounded vehicles, connect the POSITIVE (RED) clamp from the battery charger to the POSITIVE (POS, P, +) ungrounded
post of the battery. Connect the NEGATIVE (BLACK) clamp to the vehicle chassis, heavy gauge metal part of the frame, or engine block,
away from the battery. Do not connect to the carburetor, fuel lines, or sheet metal body parts.
f.
For positive-grounded vehicles, connect the NEGATIVE (BLACK) clamp from the battery charger to the NEGATIVE (NEG, N, -)
ungrounded post of the battery. Attach the POSITIVE (RED) clamp to the vehicle chassis or engine block away from the battery. Do not
connect the clamp to the carburetor, fuel lines, or sheet-metal body parts.
g.
When disconnecting the charger, turn the switches to OFF, disconnect the AC cord, remove the clamp from the vehicle chassis, and then
remove the clamp from the battery terminal.
h.
See the operating instructions for length of charge information.
FOLLOW THESE STEPS WHEN THE BATTERY IS OUTSIDE THE VEHICLE. A SPARK NEAR THE
18.
BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE
BATTERY:
a.
Check the polarity of the battery post. The POSITIVE (POS, P, +) usually has a larger diameter
than the NEGATIVE (NEG, N, -) post.
b.
Attach at least a 24 inch long 6-gauge (AWG) insulated battery cable to the NEGATIVE (NEG, N,
-) battery post.
c.
Connect the POSITIVE (RED) charger clamp to the POSITIVE (POS, P, +) post of the battery.
d.
Position yourself and the free end of the cable as far away from the battery as possible, and then
connect the NEGATIVE (BLACK) charger clamp to the free end of cable.
e.
Do not face the battery when making the final connection.
f.
When disconnecting the charger, always do so in reverse sequence of connecting procedure, and break the first connection while
standing as far away from the battery as practical.
g.
A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially designed for marine
use.
GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS
19.
The charger should be grounded to reduce the risk of electric shock. This charger is equipped with an electric cord having an equipment
grounding conductor and a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with
all local codes and ordinances.
LENGTH OF CHARGE
20.
a.
Test the battery for state of charge. Do not charge if it is over 75% charged or the battery is determined to be defective.
b.
Set beginning amps charge rate for size of battery and state of charge per charts.
c.
Charge for length of time per charge.
d.
Discontinue charge when the specific gravity of electrolyte reaches 1.260 or above. A temperature compensating hydrometer should be
used for this reading. Discontinue charge if the battery begins to gas excessively or if the temperature of the electrolyte reaches
approximately 125F. Do not overcharge batteries. Overcharging results in excessive water loss and eventual damage to the battery.
