position and removing AC cord from electric outlet. Never allow clips to touch each other.
2. Attach clips to battery posts and twist or rock back and forth several times to make
a good connection. This tends to keep clips from slipping off terminate and helps to reduce
risk of sparking.
G. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK NEAR
BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF SPARK NEAR
BATTERY, DO AS FOLLOWS:
1. Position AC and DC cords to reduce risk of damage by hood, door, or moving engine
part.
2. Stay clear of fan blades, belts, pulleys, and other parts that coo cause injury to persons.
3. Check polarity of battery posts. POSITIVE (POS, P. + ) battery post usually has larger
diameter than NEGATIVE (NEG, N. - ) post.
4. Determine which post of battery is grounded (connected to the chassis). If negative
post is grounded to chassis (as in mast vehicles), see #5. If positive post is grounded
to the chassis, see #6.
5. For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to
POSITIVE (POS, P. + ) ungrounded post of battery. Connect NEGATIVE (BLACK) clip to
vehicle chassis or engine block away from battery. Do not connect clip to carburetor, fuel
lines, or sheet-metal body puts. Connect to a heavy gage metal part of the frame or engine
block.
6. For positive-grounded vehicle, connect NEGATIVE (BLACK) clip from battery charger
to NEGATIVE (NEG, N. -) ungrounded post of battery. Connect POSITIVE (RED) clip to
vehicle chassis or engine block away from battery. Do not connect clip to carburetor, fuel
lines, or sheet-metal body parts. Connect to a heavy gage metal part of the frame or engine
block.
7. When disconnecting charger, turn switches to off, disconnect AC cord, remove clip
from vehicle chassis, and then remove clip from battery terminal, in that order.
8. See operating instructions for length of charge information.
H. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR THE
BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR
BATTERY, DO AS FOLLOWS:
1. Check polarity of battery posts. POSITIVE (POS, P. + ) battery post usually has a larger
diameter than NEGATIVE (NEG, N. - ) post.
2. Attach at least a 24-inch-long 6-gauge (AWG) insulated battery cable to NEGATIVE
(NEG, N. - ) battery post.
3. Connect POSITIVE (RED) charger clip to POSITIVE (POS, P. + ) post of battery.
4. Position yourself and free end of cable as far away from battery as possible-then
connect NEGATIVE (BLACK) charger clip to free end of cable.
5. Do not face battery when making final connection.
6. When disconnecting charger, always do so in reverse sequence of connecting
procedure and break first connection while as far away from battery as practical.
7. A marine (boat) battery must be removed and charged on shore. To charge it on board
requires equipment specially designed for marine use.
I. GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS
Charger should be grounded to reduce risk of electric shock. 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 AC cord or plug provided - if it will not fit outlet, have proper outlet
