DC CONNECTION PRECAUTIONS

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.

17.

FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN A VEHICLE. A SPARK NEAR THE
BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE
BATTERY:

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".

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.

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.

18.

FOLLOW THESE STEPS WHEN THE BATTERY IS OUTSIDE THE VEHICLE. A SPARK NEAR THE
BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE
BATTERY:

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 then connect the NEGATIVE (BLACK) charger

clamp to the free end of cable.

Do not face the battery when making the final connection.

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

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.

DANGER;

Never alter the AC cord or plug provided - if it will not fit

the outlet, have a proper outlet installed by a qualified electrician.

Improper connection can result in a risk of an electric shock. This

battery charger is for use on a nominal 120-volt circuit, and has a

grounding plug that looks like the plug illustrated in FIGURE (A). A

temporary adapter, which looks like the adapter illustrated in FIGURE

(C), may be used to connect this plug to a two-pole receptacle, as

shown in FIGURE (B), until a properly grounded outlet can be

installed by a qualified electrician.

DANGER;

Before using an adapter as illustrated, be certain that the center screw of the outlet plate is grounded. The green-colored rigid

ear or lug extending from the adapter must be connected to a properly grounded outlet - make certain it is grounded. If necessary, replace the

original outlet cover plate screw with a longer screw that will secure the adapter ear or lug to the outlet cover plate and make ground connection

to grounded outlet.

NOTE: USE OF AN ADAPTER IS NOT ALLOWED IN CANADA. IF A GROUNDING TYPE RECEPTACLE IS NOT AVAILABLE, DO NOT USE

THIS APPLIANCE UNTIL THE PROPER OUTLET IS INSTALLED BY A QUALIFIED ELECTRICIAN.

20.

LENGTH OF CHARGE

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 when the temperature of the electrolyte reaches
approximately 120°F. Do not overcharge batteries. Overcharging results in excessive water loss and eventual damage to the battery.
