B. 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.

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

C. PREPARING TO CHARGE

1.Make sure you have a 16 volt lead-acid battery.

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.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.

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

D. LED DISPLAY

LED Indicators: The battery charger has three LED lights. They indicate different functions.

RED LED - A steady glow indicates POWER ON. Red LED flashes if there is a problem. (i.e. battery isn't charged within 8 hours).

YELLOW LED - A steady glow indicates proper connection to the battery. Flashing yellow indicates no connection or reverse connection.

GREEN LED - A steady glow indicates that Float-mode Monitoring is keeping your battery maintained at full charge.

As a safety precaution, after 24-hours of charging, the charger automatically switchs OFF.

E. 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: Clicking sound is normal. Wait until charger automatically resets itself.

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