Battery Handling

How to Handle Battery

CAUTION: If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt booster battery.

After connecting battery cables, ensure that they are tightly clamped to battery terminals for good contact.

Never add distilled water through the hole used to check specific gravity.

When working with batteries, always wear appropriate eye protection.


WARNING: Do not allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces.

After touching a battery, do not touch or rub your eyes until you have thoroughly washed your hands.

If acid contacts eyes, skin or clothing, immediately flush with water for
15 minutes and seek medical attention.
