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
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 chas-
sis, 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 vehicle, connect NEGATIVE (BLACK) clamp
from the battery charger to the NEGATIVE (NEG, N, -) ungrounded
post of the battery. Connect 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. Con-
nect to a heavy gauge metal part of the frame or engine block.
g. When disconnecting the charger, turn the switches to OFF, discon-
nect 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 A 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 free end of cable as far away from the battery
as possible - 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 stand-
ing 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 CONNEC-
TION 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 ac-
cordance with all local codes and ordinances.
DANGER:
Never alter the AC cord or plug provided - if it will not fit

NOTES:
FOUR SECOND DELAY - To avoid sparking, the charger tests for correct
polarity before applying current to the battery. When connected properly,
the green light will come on for 4 seconds before the yellow light comes
on.

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 FIG-
URE (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.
CHARGE PERIOD
The approximate required time to bring a battery to full charge state
depends upon the number of ampere hours (AH) depleted from the
battery. AH are determined by multiplying the number of hours times
the number of Amps supplied by a battery to a load and normally
indicated on the battery. For example, if a load was connected to a
battery, which drew 7 Amps for a period of 5 hours, the battery will
have supplied 35 AH. The approximate recharge time would then be
calculated by dividing the 35 AH depleted from the battery, by the
ampere charge rate of the charger. To allow for tapering of the
charge rate add 25 percent to the charge time.
OPERATING INSTRUCTIONS: CHARGING
SLOW BLINKING RED LIGHT - Indicates possible weak battery.
FAST BLINKING RED LIGHT – Before charge, this indicates battery
is connected backwards, check connection.
CONTINUOUS RED LIGHT - Indicates AC power is on.
RED FLASH OFF EVERY 5 SEC – Charger believes it's connected
to a 24V battery.
CONTINUOUS GREEN LIGHT - Indicates correct connection. If
when battery is connected, the green light does not light, check for
proper polarity or poor connections. If the battery voltage is below 4
volts the green light will not come on.
BLINKING GREEN LIGHT - Indicates charge is complete, charger in
the float mode.
CONTINUOUS YELLOW LIGHT - Indicates charging, bulk charge,
less than 80% charged.
BLINKING YELLOW LIGHT - Indicates finish charge, greater
than 80% charged.
FLASHING GREEN AND YELLOW LIGHTS - Indicates flooded
batteries only. Indicates deep discharge recovery process.
