h. Use this charger for charging a LEAD-ACID battery only. It is not intended to supply power to a low-voltage electrical system
other than in an automotive application. Do not use this battery charger for charging dry-cell batteries that are commonly used
with home appliances. These batteries may burst and cause injury to persons and damage to property.
I. NEVER charge a frozen battery.

PREPARING TO CHARGE
a. If necessary to remove battery from vehicle to charge, always remove 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 the battery is well ventilated while battery is being charged. Gas can be forcefully blown away by using a
piece of cardboard or other non-metallic material as a fan.
c. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
d. Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. This helps purge excessive
gas from cells. Do not overfill. For a battery without cell caps, carefully follow manufacturer's recharging instructions.
e. Study all battery manufacturer's specific precautions such as removing or not removing cell caps while charging and
recommended rates of charge.
f. 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.

CHARGER LOCATION
a. Locate charger as far away from battery as DC 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.
16.
DC CONNECTION PRECAUTIONS
a. Connect and disconnect DC output clamps only after setting charger switches to OFF position and removing AC cord from
electric outlet. Never allow clamps to touch each other.
b. Attach DC clamps to battery post and twist or rock back and forth several times to make a good connection. This tends to
keep clamps from slipping off terminals and helps to reduce risk of sparking.
17. 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 the hood, 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 (e). If positive post is grounded to the chassis, see (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 carburetor, fuel lines, or sheet metal body parts. Connect to a heavy gage 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. Attach POSITIVE (RED) clamp to vehicle chassis or engine block away from the battery. Do not
connect the clamp to the carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gage metal part of the frame or
engine block.
g. When disconnecting charger, turn switches to OFF, disconnect AC cord, remove clamp from vehicle chassis, and then remove
clamp from battery terminal.
h. See operating instructions for length of charge information.

FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR BATTERY MAY CAUSE
BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY:
a. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than NEGATIVE (NEG, N, -)
post.
b. Attach at least a 24 inch long 6-gauge (AWG) insulated battery cable to NEGATIVE (NEG, N, -) battery post.
c. Connect POSITIVE (RED) charger clamp to POSITIVE (POS, P, +) post of battery.
d. Position yourself and free end of cable as far away from battery as possible, then connect NEGATIVE (BLACK) charger clamp
to free end of cable.
e. Do not face battery when making final connection.
f. When disconnecting charger, always do so in reverse sequence of connecting procedure, and break the first connection while
as far away from 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.
