PERSONAL PRECAUTIONS AND SAFETY

1. WARNING: Wear complete eye protection and clothing

protection, when working with lead-acid batteries.

2. Make sure someone is within range of your voice or close enough to come to your aid when you work with or near a lead-acid battery.

3. Have plenty of fresh water and soap nearby for use if battery acid contacts skin, clothing, or eyes. If battery acid contacts skin or clothing, wash immediately with soap and water.

4. Avoid touching your eyes while working with a battery. Acid particles (corrosion) may get into your eyes! If acid enters your eye, immediately flood eye with running cold water for at least 10 minutes. Get medical attention immediately.

5. Remove all personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. 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.

PREPARING TO CHARGE

6. Take care not to drop a metal tool or other metal onto the battery. Metal may cause sparking or short circuit the battery or another electrical device. Sparking may cause an explosion.

7. Always operate battery charger in an open well ventilated area.

8. Battery chargers get hot during operation and must have proper ventilation. Air needs to flow around entire charger.

9. Do not set battery charger on flammable items like carpeting, upholstery, paper, cardboard etc. Charger may damage leather and melt plastic and rubber.

10. NEVER smoke or allow a spark or flame in the vicinity of the battery or engine. Batteries generate explosive gases!

11. WARNING: Handling the cord on this product or cords

associated with accessories sold with this product, will expose you to lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.

Wash hands after handling.

1. Make sure you have a 12 volt lead-acid battery. Check owner manual to make sure.

2. Clean battery terminals. Take care to keep corrosion from coming in contact with your eyes.

3. If required, add distilled water in each cell until battery acid reaches levels 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.

4. Study all battery manufacturer's specific precautions, such as removing or not removing cell caps while charging, and recommended rates of charge.

5. 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.

6. A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially designed for marine use.

OFF - ON SWITCH

Make sure On/Off switch is in the Off position when connecting and disconnecting charger to battery.

AUTOMATIC CHARGING

When the battery reaches the full charge state, charge current is turned off and the charger switches to the maintainer mode of operation. This action occurs when the charge tapers down to approximately 5 Amps. In this state the battery voltage is constantly being monitored. When the battery voltage drops to a predetermined value charge will turn on for a few seconds replacing the small amount of energy that was lost while the charge current was at 0 Amps.

CHARGE COMPLETE INDICATOR

When the battery reaches the full charged state, the right LED indicator light will glow green.

NOTE: As the battery approaches the full charge state the LED will fluctuate on and off between CHARGING and CHARGED. For the average size automotive battery, allow 5 to 10 minutes for the battery to stabilize.

REVERSED CONNECTION INDICATOR

If clamps are attached incorrectly to the battery posts, example: negative to positive or positive to negative, the right LED will glow red. When connected properly, no LED will glow.

POWER ON INDICATOR

The Power On LED Indicator will glow green when the unit is turned ON and it is plugged into 120 Volt electrical outlet. Charging begins once clamps are connected to the battery.

CIRCUIT BREAKER

This battery charger is equipped with a self-resetting circuit breaker. This device protects the charger from temporary overloads. In the event of an overload, the circuit breaker will trip open and after a short cooling off period will reset automatically. This process is known as cycling and can be recognized by an audible clicking sound.

NOTE:

cally resets itself.

CAUTION: Persistent clicking (more than 30 minutes) may indicate reverse connection or shorted battery cells. (See TROUBLE- SHOOTING)

Clicking sound is normal. Wait until charger automati-

BATTERY TYPES

Three basic types of lead-acid batteries can be given a charge with this charger: (1) Conventional and Low Maintenance, (2) Maintenance Free, (3) Deep Cycle / Marine.

Conventional and Low Maintenance Batteries. These are the antimony/lead batteries. Conventional/Low Maintenance batteries require periodic addition of water to the acid solution (electrolyte). Additional water may be added by removing the filler caps located on the top of the battery.

IMPORTANT: When antimony is known to be one of the materials used in the battery's construction, that battery is a Low Maintenance/Conventional type.

CAUTION: Some Low Maintenance batteries have a relatively smooth top without any apparent battery filler caps. If, however, the battery manufacturer/distributor recommends periodic checking of electrolyte level and provides access to the battery

for water additions, the battery is probably a Low Maintenance/ Conventional type.

Maintenance Free Batteries. These are calcium/lead batteries and normally do not require water additions. Therefore, filler caps have been removed from the battery surface. These batteries will have a smooth or sealed appearance.

Deep Cycle Batteries. These heavy duty batteries are used in boats, construction equipment, sump pumps, etc. They are normally marked DEEP CYCLE on the outside of the case.

OPERATING INSTRUCTIONS: CHARGING BATTERY OUT OF THE VEHICLE

When charging battery, take care to determine the battery type. To reduce risk of a spark near battery, follow these steps.

WARNING: A spark near battery may cause battery explosion.

WARNING: When removing battery from vehicle or boat, disconnect grounded pole first. When disconnecting, make sure the engine/motor

and all accessories are off, so as not to cause an arc.

(NOTE: BOAT BATTERIES MUST BE REMOVED AND CHARGED ON SHORE. (TO SAFELY CHARGE ON BOARD REQUIRES

SPECIAL EQUIPMENT ESPECIALLY DESIGNED AND UL LISTED FOR MARINE USE. THIS CHARGER IS NOT WATER RESISTANT AND SHOULD NOT BE EXPOSED TO WET CONDITIONS.)

WARNING: When reinstalling battery, attach the ground post first.

(Continued…)

1. Check polarity of battery posts. Battery case will be marked by each post: POSITIVE (POS, P, +) and NEGATIVE (NEG, N,

-). NOTE: The positive battery post usually has a larger diam- eter than the negative post.
