3.5 Study all battery manufacturer’s specific precautions while charging and
recommended rates of charge.
3.6 Determine voltage of battery by referring to car owner’s manual and make sure that
output voltage selector switch is set at correct voltage. If charger has adjustable charge
rate, charge battery initially at lowest rate.
4. CHARGER LOCATION
4.1 Locate charger as far away from battery as DC cables permit.
4.2 Never place charger directly above battery being charged; gases from battery will
corrode and damage charger.
4.3 Never allow battery acid to drip on charger when reading electrolyte specific
gravity or filling battery.
4.4 Do not operate charger in a closed-in area or restrict ventilation in any way.
4.5 Do not set a battery on top of charger.
5. DC CONNECTION PRECAUTIONS
5.1 Connect and disconnect DC output clips only after setting any charger switches to
“off” position and removing AC cord from electric outlet. Never allow clips to touch
each other.
5.2 Attach clips to battery and chassis, as indicated in sections 6 and 7.
6. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE
WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY
EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
6.1 Position AC and DC cords to reduce risk of damage by hood, door, or moving engine part.
6.2 Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
6.3 Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has
larger diameter than NEGATIVE (NEG, N,–) post.
6.4 Determine which post of battery is grounded (connected) to the chassis. If
negative post is grounded to chassis (as in most vehicles), see (6.5). If positive
post is grounded to the chassis, see (6.6).
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 gauge
metal part of the frame or engine block.
