PERSONAL PRECAUTIONS

• Someone should be within range of your voice or close enough to come to your aid when you work near a lead-acid battery. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes. Wear complete eye and clothing protection. Avoid touching eyes while working near the battery.
• If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flush eye with running cold water for at least 10 minutes and get medical attention immediately.
• NEVER smoke or allow a spark or flame in the vicinity of the battery or engine.
• Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might spark or short-circuit the battery or another electrical part that may cause an explosion.
• When working with a lead-acid battery, remove personal metal items such as rings, bracelets, necklaces, watches, etc. A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn.
• Use a 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 a battery charger for charging dry-cell batteries that are commonly used with home appliances. These batteries may burst and cause bodily injury and damage to property.
• NEVER charge a frozen battery.

PREPARING TO CHARGE

• If necessary to remove the battery from the vehicle to charge, always remove the grounded terminal from the battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc. Be sure the area around the battery is well-ventilated while the battery is being charged. Gas can be forcefully blown away by using a piece of cardboard or other non-metallic material as a fan.
• Clean battery terminals. Be careful to keep corrosion from coming into contact with the eyes. Add distilled water in each cell until battery acid reaches the level specified by the battery manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery without caps, carefully follow the manufacturer’s recharging instructions.
• Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while charging and recommended rates of charge.
• Determine the voltage of the battery by contacting the battery manufacturer and make sure it matches the output ratings of the battery charger.

CHARGER LOCATION

• Locate the charger as far away from the battery as DC cables permit.
• Never place the charger directly above the battery being charged; gases from the battery will corrode and damage the charger.
• Never allow battery acid to drip on the charger when reading gravity or filling the battery.
• Do not operate charger in a closed-in area or restrict ventilation in any way.
• Do not set a battery on top of the charger.
• If an extension cord is needed, it should be a grounded, heavy-duty cord (12 gauge or better).

DC CONNECTION PRECAUTIONS

• Connect and disconnect DC output terminals only after removing the charger from the AC outlet.
• Never allow DC output terminals to touch each other.
• If problems arise connecting the output leads, ask for help from your dealer from where you purchased this product or the charger manufacturer for finding a suitable connection device for your application.

FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN THE VEHICLE. A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

• Position AC and DC Cords to reduce the risk of damage by the hood, door or moving engine part.
• Stay clear of fan blades, belts, pulleys, and any other parts that can cause injury to persons.
• Check the polarity of battery posts POSITIVE (POS.,P,+) post usually has a larger diameter than NEGATIVE (NEG.,N,-)
• Determine which post of the battery is grounded (connected) to the chassis.
• For a negative-grounded vehicle, first connect the POSITIVE (RED) clip from the charger to the POSITIVE (POS.,P,+) ungrounded post of the battery. Then connect the NEGATIVE (BLACK) terminal to the vehicle chassis or engine block away from the battery.
• For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the charger to the NEGATIVE (NEG.,N,) ungrounded post of the battery. Connect POSITIVE (RED) dip to the vehicle chassis or engine block away from the battery keeping the battery terminal separated from the connection to the chassis.
• Do not connect any charger clips to the carburetor, fuel lines, or sheet metal body parts. Connect to a heavy gauge metal part of the frame or engine block.
• Connect the AC supply cord charger to an electric outlet.
• When disconnecting the charger, turn the switches (if supplied) to off, disconnect the charger from AC power, remove the clip from the vehicle chassis, and then remove clip from the battery terminal. See operating instructions for length of charge information.
• Make sure the battery type selection switch position is correct.
• See operating instructions for length of charge information.

FOLLOW THESE STEPS WHEN BATTERY IS OUTsIDE VEHICLE. A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

• Check the polarity of battery posts. POSITIVE (POS.,P,+) battery post usually has a larger diameter than NEGATIVE (NEG.,N,-) post. Some batteries are equipped with “wing-nut” terminals allowing for easy placement of the terminals to these posts.
• Attach at least a 24-inch long 6 gauge (AWG) insulated battery cable to the NEGATIVE (NEG.,N-) battery post.
• Connect the PoSITIVE (RED) charger terminal to the POSITIVE (POS.,P,+) post of the battery.
• Position yourself and free end of the cable as far away from the battery as possible, then connect the NEGATIVE (BLACK) terminal to the free end of the cable.
• Do not face the battery when making the final connection.
• Connect AC supply cord charger to a power outlet.
• When disconnecting the charger, always do so in the reverse sequence of connecting procedure and break the first connection while as far away from the battery as possible.
