Page 4

Never place charger directly above battery being charged. The gases from the battery will corrode and damage the charger.

Never touch the battery clamps together when the charger is on. You could cause a spark.

Never operate charger if it has received a hard blow, been dropped, or otherwise damaged. Take it to a qualified professional for inspection and repair.

Be sure to position the charger power cord

to prevent it from being stepped on, tripped over, or damaged.

Never pull out the plug by the cord when unplugging the charger. Pulling on the cord may cause damage to the cord or the plug.

Do not operate the charger if it has a damaged power cord or plug. Have the cord replaced.

Personal Safety Precautions

Wear complete eye and clothing protection when working with lead- acid batteries.

Make sure that someone is within range of your voice to come to your aid if needed while you work with or are near a lead-acid battery.

Have plenty of fresh water and soap nearby for use in case battery acid contacts your eyes, skin, or clothing. If this happens, wash immediately with soap and water. Then get medical at- tention.

Avoid touching your eyes while working with a battery. Acid particles

(corrosion) may get into your eyes. If this occurs, flush eyes immediately with running cold water for at least 10 minutes. Then immediately get medi- cal attention.

Remove all personal metal items from your body such as rings, brace- lets, necklaces and watches, while working with a lead-acid battery. A bat- tery can produce a short circuit current high enough to weld a ring (or the like) to metal, causing a severe burn.

Take care not to drop any metal tool or metal object onto the battery. This may spark or short circuit the battery or another electrical device that may cause an explosion.

Always operate the battery charger in an open, well-ventilated area.

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

Neutralize any acid spills thoroughly with baking soda before attempting to clean up.
