‹4.6.3 BATTERY MAINTENANCE

The battery should be inspected per the “Service Schedule,” Section 6. The following procedure should be followed for inspection:

1.Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary.

2.Check the battery fluid level of unsealed batteries and, if necessary, fill with DISTILLED WATER ONLY. DO NOT USE TAP WATER IN BATTERIES.

3.Have the state of charge and condition checked. This should be done with an automotive-type bat- tery hydrometer.

DANGER

Storage batteries give off explosive hydrogen gas. This gas can form an explosive mixture around the battery for several hours after charging. The slightest spark can ignite the gas and cause an explosion. Such an explosion can shatter the battery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smoking, open flame, sparks or any spark producing tools or equipment near the battery.

Battery electrolyte fluid is an extremely caustic ! sulfuric acid solution that can cause severe

burns. Do not permit fluid to contact eyes, skin, clothing, painted surfaces, etc. Wear protective goggles, protective clothing and gloves when handling a battery. If the fluid is spilled, flush the affected area immediately with clear water.

Do not use any jumper cables or booster bat- ! tery to crank and start the generator engine. If

the battery has completely discharged, remove it from the generator for recharging.

Be sure the Auto/Off/Manual switch is set to ! the OFF position before connecting the battery

cables. If the switch is set to AUTO or MANUAL, the generator can crank and start as soon as the battery cables are connected.

Be sure the utility power supply is turned off, or sparking may occur at the battery posts as the cables are attached and cause an explosion.
