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.
Battery electrolyte is poisonous. If the battery should ex-
plode battery electrolyte may be splashed into eyes, pos-
sibly resulting in blindness.
•
Be sure to wear eye protection when checking electro-
lyte specific gravity.
