BATTERY MAINTENANCE
Severe burn hazard.
A filled battery contains
sulfuric acid. Avoid contact with skin, eyes or clothing.
NOTICE:
To protect battery case from chipping and goug-
ing, do not let battery sit on concrete floor. Install battery on
a shelf or protective pad (plywood, 2x4s, etc.). Always in-
stall battery in a dry location that is protected from flooding.
Follow the battery manufacturer’s recommendations for
maintenance and safe use of battery.
