CHECKING BATTERYCONDITION
Precautions
CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and explosive
hydrogen gas.
Do not cause a spark by contacting the battery
terminals with tools.
 Do not smoke or light a match near the battery.
The electrolyte contains poisonous and corrosive
sulfuric acid.
 Avoid contact with eyes, skin or clothes.
 Never inhale or swallow electrolyte.
 Wear protective safety glasses when working near
the battery.
 Keep children away from the battery.
EMERGENCY MEASURES
 If electrolyte gets in your eyes, flush your eyes with
clean water immediately and get immediate medical
attention. If possible, continue to apply water with a
sponge or cloth while traveling to the medical office.

If electrolyte gets on your skin, thoroughly
wash the contacted area. If you feel a pain or
burn, get medical attention immediately.
 If electrolyte gets on your clothes, there is a
possibility of its soaking through to your skin,
so immediately take off the exposed clothing
and follow the procedure above, if necessary.
 If you accidentally swallow electrolyte, drink a
large quantity of water or milk. Follow with milk
of magnesia, beaten raw egg or vegetable oil.
Then go immediately for emergency help.Checking battery exterior

1Terminals 2Hold±down clamp
Check the battery for corroded or loose
connections, cracks, or loose hold±down clamps.
1. If the battery is corroded, wash it off with a solution of
warm water and baking soda. Coat the terminals with
grease to prevent further corrosion.
2. If the connections are loose, tighten the clamp bolts
± but do not overtighten.
3. Tighten the hold±down clamp only enough to keep
the battery firmly in place. Overtightening may damage
the battery case.NOTICE
Make sure the engine and all accessories are
turned off before performing maintenance.
When checking the battery, remove the ground
cable first and reinstall it last.
Be careful not to cause a short circuit with tools.
Take care no solution gets into the batterywhen washing it.
