attempting  any maintenance or cleaning.  Turning off controls will not reduce this risk. 
 
WARNING – THERE IS A RISK OF EXPLOSIVE GASSES AND 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 EXACTLY. 

 
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 . 
 

PERSONAL PRECAUTIONS:

 

1.

 

Someone  should  be  within  range  of  your  voice  or  close  enough  to  come  to  your  aid  when  you 

work near a battery. 

2.

 

Have  plenty  of  fresh  water  and  soap  nearby  in  case  the  battery  electrolyte  contacts  skin, 

clothing, or eyes. 

3.

 

Wear complete eye protection and clothing protection. Avoid touching eyes while working near a 

battery. 

4.

 

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. 

5.

 

Never smoke or allow a spark or flame in vicinity of a battery. 

6.

 

Be extra cautious, DO NOT drop metal onto a battery.  It might spark or short-circuit the battery 

or cause an explosion. 

7.

 

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.
