Part Number 601815

Avoid skin contact 
with battery acid

Do not overfill battery.

Electrolyte may overflow and damage 
paint, wiring or structure. When cleaning 
the battery, use soap and water into the 
battery. Be careful not to get soap and 
water into the battery. Use soda mixed in 
water to clean corrosion off the terminals.

Always wear eye protection when check-
ing the battery, acid can cause serious 
injury to skin and eyes. If contact occurs, 
flush area with clean water and call phy-
sician immediately. Acid will also damage 
clothing.

Do not allow open flame near the bat-
tery when charging.

Hydrogen gas forms inside the bat-
tery. This gas is both toxic and flam-
mable and may cause an explosion if 
exposed to flame. Always remove the 
negative ground first and replace it 
last.
