WARNING
!
TO PREVENT BODILY INJURY!
WEAR GOGGLES, RUBBER GLOVES
AND A PROTECTIVE APRON
WHEN WORKING WITH A BATTERY.
BATTERY POST CORROSION CAN CAUSE
SEVERE EYE DAMAGE AND SKIN BURNS.

Charging Batteries
Batteries should be charged outside the boat. Do not
smoke or bring fl ames near a battery that is being or has
recently been charged. The hydrogen gas generated by
battery charging is highly explosive.
Set the batteries on a block of wood not concrete since
the batteries will lose their charge if left on a cement
surface.
Do not allow a metal object or loose wires to spark across
battery posts while working close to the battery. Contact
across terminals will cause a short circuit and possible
electrical burns, fi re, explosion or personal injury.
