11.  WARNING - RISK OF EXPLOSIVE GASES

a)  BATTERIES GENERATE EXPLOSIVE GASES 

DURING NORMAL BATTERY OPERATION. 

FOR THIS REASON, IT IS OF THE UTMOST 

IMPORTANCE THAT EACH TIME BEFORE 

USING YOUR CHARGER, YOU READ THIS 

MANUAL AND FOLLOW THE INSTRUCTIONS 

CAREFULLY.

b)    Follow these instructions and those published by the battery manufacturer and the 

manufacturer of any equipment you intend to use in vicinity of battery. 

12. PERSONAL PRECAUTIONS

a)   Some one should be within voice range or close enough 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)   Always 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 short-circuit battery or other electrical part that may cause explosion.

g)   Remove personal metal items such as rings, bracelets, necklaces, and watches 

when working with 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. 

h)   Use charger for charging a LEAD-ACID battery only. It is not intended to supply 

power to a low voltage electrical. Do not use battery charger for dry-cell batteries 

that are commonly used with home appliances. These batteries may burst and 

cause injury to persons and damage to property.
