Prevent Battery Explosions

 Battery gas can explode.
 Keep sparks, lighted matches, and flame away from the
top of battery.
 Never check battery charge by placing a metal object
across the posts. Use a voltmeter or hydrometer.
 Do not charge a frozen battery; it may explode. Warm the
battery to 16 ˚C ( 60 ˚F ) first.
 Do not continue to use or charge the battery when
electrolyte level is lower than specified. Explosion of the
battery may result.
 Loose terminals may produce sparks. Securely tighten all
terminals.
 Connect terminals to the correct electrical poles. Failure
to do so may cause damage to the electrical parts or fire.
 Battery electrolyte is poisonous. If the battery should
explode, battery electrolyte may be splashed into eyes,
possibly resulting in blindness.
 Be sure to wear eye protection when checking electrolyte
specific gravity.

Service Air Conditioning System Safely
