1. Someone should be within range of your voice or close enough to come to your aid when you work near a
lead-acid or other battery.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
3. Wear complete eye protection, and clothing protection. Avoid touching eyes while working near battery.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enter eye, immediately
flood eye with running cold water for at least 10 minutes and get medical attention immediately.
5. NEVER smoke or allow a spark or flame in vicinity of battery or engine.
6 Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short circuit battery or
other electrical part that may cause explosion.
7. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid
or other battery. A lead-acid or other battery can produce a short circuit current high enough to weld a ring or the
like to metal, causing a severe burn.
8. Use the charger for charging a LEAD-ACID battery only. It is not intended to supply power to a low-voltage
electrical system other than in a starter motor application. Do not use 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.
9. NEVER charge a frozen battery.
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. 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 the 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 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 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 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.
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 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 chassi 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 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. Connect POSITIVE (RED) 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.
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.
