eyewear when working with batteries.  

  
Avoid spilling or  contacting battery acid. Neutralize battery 

acid spills with baking soda and water. Do not expose the 
batteries or the charger to water or rain during charging. 

 

 

Explosion Hazards  

Keep  sparks,  flames  and  lighted 
tobacco away from batteries. Batteries 
emit an explosive gas.  
  
The  battery  tray  should  remain  open 
during the entire charging cycle.  

 

 

Do not contact the battery terminals or the cable clamps with 

tools that may cause sparks.

  

 

Component Damage Hazard  

Do not use any battery charger greater than 24V to charge 

the batteries.  

  

Electrocution Hazards

 

 

 

 

Connect  the  battery  charger  to 

grounded, 

AC 

3-wire 

electrical  outlet  only.  Inspect

items before operating.  
  

Avoid electrical shock from contact with battery 

terminals. Remove all rings, watches and other 
jewelry.  

  

Tip-over Hazard  

Do not use batteries that weigh less than the 

original equipment. Batteries are used as 
Counterweight and are critical to machine 
stability Each battery must weigh 65 pounds / 28 
kg.
