JUMP-STARTING
Battery Explosion - Avoid
Do not jump-start or charge a battery that is frozen or low on electrolyte.
Avoid explosion hazard.
Do not allow vehicle used to jump-start to be in contact with the disabled machine. Vehicles in contact have a
ground connection which allows a spark to occur at the battery when the positive jumper cable is connected or
removed. If equipped with battery caps, they must be in place and tight to reduce risk of battery explosion.
IMPORTANT: Use only a 12-volt system for jump-starting.
Battery Burns - Avoid
Battery contains sulfuric acid which can cause severe burns. Avoid contact with eyes, skin, and clothing.

External: Flush with plenty of water. If eyes have been exposed, flush with water for 15 minutes and get
prompt medical attention.
Internal: Drink large quantities of water or milk, follow with milk of magnesia, beaten egg, or vegetable oil.
Call a physician immediately.
WARNING: Battery fumes are flammable and can explode. Keep all burning materials away
from battery. Battery explosion can blind. Acid can blind and burn. Tools and cable clamps can
make sparks.
