10. WARNING – RISK OF
EXPLOSIVE GASES.

a. WORKING IN VICINITY OF A LEAD-

ACID BATTERY IS DANGEROUS.
BATTERIES GENERATE EXPLOSIVE
GASES DURING NORMAL
BATTERY OPERATION. FOR THIS
REASON, IT IS OF UTMOST
IMPORTANCE THAT YOU FOLLOW
THE INSTRUCTIONS EACH TIME
YOU USE THE CHARGER.

b. To reduce risk of battery explosion,

follow these instructions and those
published by battery manufacturer and
manufacturer of any equipment you
intend to use in vicinity of battery.
Review cautionary marking on
these products and on engine.

11. PERSONAL PRECAUTIONS

a. Consider having someone close

enough by to come to your aid when
you work near a lead-acid battery.

b. Have plenty of fresh water and

soap nearby in case battery acid
contacts skin, clothing, or eyes.

c. Wear complete eye protection and

clothing protection. Avoid touching
eyes while working near battery.

d. If battery acid contacts skin or

clothing, wash immediately with
soap and water. If acid enters eye,
immediately flood eye with running
cold water for at least 10 minutes and
get medical attention immediately.

e. NEVER smoke or allow a spark or

flame in vicinity of battery or engine.

f. Be extra cautious to reduce risk

of dropping a metal tool onto
battery. It might spark or short­circuit battery or other electrical
part that may cause explosion.

g. Remove personal metal items such

as rings, bracelets, necklaces, and
watches when working with a lead­acid 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.

h. Use charger for charging LEAD-ACID

or Absorbed Glass Mat (AGM) batteries
only. It is not intended to supply power
to a low voltage electrical system other
than in a starter-motor application.
