Risk of Explosive Gasses

a. WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE CHARGER.
b. To reduce the risk of a battery explosion, follow these instructions and those published by the battery manufacturer and the manufacturer of any equipment you intend to use in the vicinity of the battery. Review the cautionary markings on these products and on the engine.
c. This charger employs parts such as switches and circuit breakers, that tend to produce arcs and sparks. If used in a garage, locate this charger 18 inches (46 cm) or more above the floor level.
d. NEVER smoke or allow a spark or flame in the vicinity of a battery or engine.
e. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery that can produce a short-circuit battery or another electrical part that may cause an explosion.
f. Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might spark or short-circuit the battery or other electrical parts that may cause an explosion.
g. Use this charger for charging LEAD-ACID batteries only. It is not intended to supply power to a low voltage electrical system other than in a starter- motor 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.
h. NEVER charge a frozen battery.
i. NEVER overcharge a battery.
j. Consider having someone close enough by to come to your aid when you work near a lead-acid battery.
k. Have plenty of fresh water and soap nearby in case battery acid contacts your skin, clothing, or eyes.
l. Wear complete eye and body protection, including safety goggles and protective clothing. Avoid touching your eyes while working near the battery.
m. If battery acid contacts your skin or clothing, immediately wash the area with soap and water. If acid enters your eye, immediately flood the eye with cold running water for at least 10 minutes and get medical attention right away.
n. If battery acid is accidentally swallowed, drink milk, the whites of eggs, or water. DO NOT induce vomiting. Seek medical attention immediately.

Preparing to Charge

a. If it is necessary to remove the battery from the vehicle to charge it, always remove the grounded terminal first. Make sure all of the accessories in the vehicle are off to prevent arcing.
b. Be sure the area around the battery is well ventilated while the battery is being charged.
c. Clean the battery terminals before charging the battery. During cleaning, keep airborne corrosion from coming into contact with your eyes, nose, and mouth. Use baking soda and water to neutralize the battery acid and help eliminate airborne corrosion. Do not touch your eyes, nose, or mouth.
d. Add distilled water to each cell until the battery acid reaches the level specified by the battery manufacturer. Do not overfill. For a battery without removable cell caps, such as valve-regulated lead-acid batteries (VRLA), carefully follow the manufacturer’s recharging instructions.
e. Read, understand and follow all instructions for the charger, battery, vehicle, and any equipment used near the battery and charger. Study all of the battery manufacturer’s specific precautions while charging and recommended rates of charge.
f. Determine the voltage of the battery by referring to the vehicle owner’s manual and make sure that the output voltage selector switch is set to the correct voltage. If the charger has an adjustable charge rate, charge the battery at the lowest rate first.
g. Make sure that the charger cable clips make tight connections.

Charger Location

a. Locate the charger as far away from the battery as the DC cables permit.
b. Never place the charger directly above the battery being charged; gases from the battery will corrode and damage the charger.
c. Do not set the battery on top of the charger.
d. Never allow battery acid to drip onto the charger when reading the electrolyte specific gravity or filling the battery.
e. Do not operate the charger in a closed-in area or strict the ventilation in any way.

DC Connection Precautions

a. Connect and disconnect the DC output clips only after removing the AC plug from the electrical outlet. Never allow the clips to touch each other.
b. Attach the clips to the battery and chassis, as indicated in sections 6 and 7.

Follow these steps when the battery is installed in the vehicle.

a. Position the AC and DC cables to reduce the risk of damage by the hood, door, and moving or hot engine parts. NOTE: If it is necessary to close the hood during the charging process, ensure that the hood does not touch the metal part of the battery clips or cut the insulation of the cables.
b. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury.
c. Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE (NEG, N, -) post.
d. Determine which post of the battery is grounded (connected) to the chassis. If the negative post is grounded to the chassis (as in most vehicles), see step 6.5. If the positive post is grounded to the chassis, see step 6.6.
e. For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the battery charger to the POSITIVE (POS, P, +) ungrounded post of the battery. Connect the NEGATIVE (BLACK) clip to the vehicle chassis or engine block away from the battery. Do not connect the clip to the carburetor,
fuel lines, or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine block.
f. For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the battery charger to the NEGATIVE (NEG, N, -) ungrounded post of the battery. Connect the POSITIVE (RED) clip to the vehicle chassis or engine block away from the battery. Do not connect the clip to the carburetor,
fuel lines, or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine block.
g. When disconnecting the charger, turn all switches off, disconnect the AC cord, remove the clip from the vehicle chassis and then remove the clip from the battery terminal.
h. See CALCULATING CHARGE TIME for a length of charge information.

Follow these steps when the battery is outside the vehicle.

a. Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE (NEG, N, -) post.
b. Attach at least a 24-inch (61 cm) long 6-gauge (AWG) (13mm²) insulated battery cable to the NEGATIVE (NEG, N, -) battery post.
c. Connect the POSITIVE (RED) charger clip to the POSITIVE (POS, P, +) post of the battery. d. Position yourself and the free end of the cable you previously attached to the NEGATIVE (NEG, N, -) battery post as far away from the battery as possible – then connect the NEGATIVE (BLACK)
charger clip to the free end of the cable.
e. Do not face the battery when making the final connection.
f. When disconnecting the charger, always do so in the reverse order of the connecting procedure and break the first connection while as far away from the battery as practical.
g. A marine (boat) battery must be removed and charged onshore. To charge it on board requires equipment specially designed for marine use.

Before Returning for Repairs

a. When a charging problem arises, make certain that the battery is capable of accepting a normal charge. Use a good battery to double-check all connections, the AC outlet for a full 120-volts, the charger clips for correct polarity, and the quality of the connections from the cables to the clips
and from the clips to the battery system. The clips must be clean.
b. When a battery is very cold, partially charged, or sulfated, it will not draw the full rated amperes from the charger. It is both dangerous and damaging to a battery to force higher amperage into it
then it can effectively use in recharging.
c. When an UNKNOWN OPERATING PROBLEM arises, please read the complete manual and call the user service number for information that will usually eliminate the need for return.
