4. Do not operate charger in a closed-in area or restrict ventilation in any way.
5. Do not set a battery on top of charger.
6. Do not expose charger to rain or snow.
F. DC CONNECTION PRECAUTIONS
1. Connect and disconnect DC output clips only after removing AC cord from electric
outlet. Never allow clips to touch each other.
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 terminals 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
parts.
2. Stay clear of fan blades, belts, pulleys and other parts that can cause injury to persons.
3. Check polarity of battery posts. POSITIVE (POS, P. +) battery post usually has larger
diameter 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 most 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 parts. 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, 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 con-
nect 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 proce-
dure and break first connection while as far away from battery as practical.
