FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK NEAR BATTERY MAY CAUSE BATTERY
EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY:
a. Position AC and DC cords to reduce risk of damage by bonnet, door, or moving engine part.
b. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
c. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N, -) post.
d. Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to chassis (as in most
vehicles), see item “e”. If positive post is grounded to the chassis, see item “f”.
e. For negative-grounded vehicle, connect POSITIVE (RED) clamp from battery charger to POSITIVE (POS, P, +) ungrounded post
of battery.
Connect NEGATIVE (BLACK) clamp to vehicle chassis or engine block away from battery. Do not connect clamp to carburettor,
fuel lines, or sheet metal body parts. Connect to a heavy gauge metal part of the frame or engine block.
f. For positive-grounded vehicle, connect NEGATIVE (BLACK) clamp from battery charger to NEGATIVE (NEG, N, -) ungrounded
post of battery. Connect POSITIVE (RED) clamp to vehicle chassis or engine block away from battery. Do not connect clamp to
carburettor, fuel lines, or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine block.
OPERATING INSTRUCTIONS
PREPARING TO CHARGE
a. If necessary to remove battery from vehicle to charge, always remove the grounded terminal from battery first. Make sure all
accessories in the vehicle are off, so as not to cause an arc.
b. Be sure area around battery is well ventilated while battery is being charged.
c. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
d. Study all the battery manufacturer’s specific precautions such as removing or not removing cell caps while charging and
recommended rates of charge.
CHARGER LOCATION
a. Locate charger as far away from battery as output cables permit.
b. Never place charger directly above battery being charged; gases from battery will corrode and damage charger.
c. Never allow battery acid to drip on charger when reading gravity or filling battery,
d. Do not operate charger in a closed-in area, or restrict ventilation in any way.
e. Do not set a battery on top of charger.
DC CONNECTION PRECAUTIONS
a. Connect and disconnect DC output clamps only after setting any charger switches to off position and removing ac cord from
electric outlet. Never allow clamps to touch each other.
b. Attach clamps to the battery posts and twist or rock back and forth several times to make a good connection. This tends to keep
the clamps from slipping off terminals and helps to reduce risk of sparking.
