1. WARNING: Wear complete eye protection and clothing pro-
tection, 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 bat-
tery 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 bat-
tery. 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 bat-
tery 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 carpet-
ing, upholstery, paper, cardboard etc. Charger may dam-
age 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 as-
sociated with accessories sold with this product, will ex-
pose you to lead, a chemical known to the State of Califor-
nia 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 bat-
tery without cell caps, carefully follow manufacturer's re-
charging 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 us-
ing 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.
