WARNING
– RISK OF EXPLOSIVE GASES
a.
Working in the vicinity of a battery is dangerous. Some batteries generate explosive gases during normal battery operation. For this
reason, it is of utmost importance that each time before using this unit, you read this manual and follow the instructions
b.
To reduce risk of battery explosion, follow these instructions and those published by the battery manufacturer and manufacturer of
any equipment you intend to use in the vicinity of the battery. Review cautionary marking on all products.
8. PERSONAL PRECAUTIONS:
a.
Someone should be within range of your voice or close enough to come to your aid when you work near a battery.
b.
Have plenty of fresh water and soap nearby in case the battery electrolyte contacts skin, clothing, or eyes.
c.
Wear complete eye protection and clothing protection. Avoid touching eyes while working near a battery.
d.
If the battery electrolyte contacts skin or clothing, wash immediately with soap and water. If the electrolyte enters the eye,
immediately flood the eye with running cold water for at least ten (10) minutes and get medical attention immediately.

f.
Be extra cautious, DO NOT drop metal onto a battery. It might spark or short-circuit the battery or cause an explosion.
g.
Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a battery. A battery can produce a
short-circuit current high enough to weld these items causing severe burns.
h.
NEVER charge a frozen battery.
