with cool water. In serious cases or if eye contact
is made, seek medical attention IMMEDIATELY.

the caps of the battery cells are removed, NEVER
look directly into them while charging batteries.

tery cell holes.
3. Clean the terminals and inside the battery clamps by
using a battery cleaning tool, wire brush, or medium
grade sand paper.
NOTE: When done, these areas should be shiny, not dull.
