LITHIUM ION

 BATTERY PACKS

.  The use of other 

types of batteries or equipment may result in personal injury or 
equipment damage.  Under no circumstances attempt to connect the 
charger to any power supplies or other equipment that is not specifically 
and expressly designated for use with this model charger. 
 

2.

  

AVOID DANGEROUS CONDITIONS AND ENVIRONMENTS

.  Do 

not charge battery packs in damp or wet conditions.  Avoid using the 
charger in direct exposure to rain or snow.  Do not use the battery pack 
or charger in the presence of explosive gases or flammable materials 
because sparks will be generated whenever a battery pack is plugged or
