MISCELLANEOUS MAINTENANCE

‹CLEANING THE GENERATOR

Keep the generator as clean and as dry as possible. Dirt and moisture that accumulates on internal gen- erator windings have an adverse effect on insulation resistance.

Periodically clean generator exterior surfaces. A soft brush may be used to loosen caked on dirt. Use a vacuum system or dry, low pressure air to remove any accumulations of dirt. The generator is housed inside an all-weather enclosure, clean the enclosure with a soft, damp cloth or sponge and water.

Once each year have the generator cleaned and inspected by an Authorized Service Dealer. That dealer will use dry, low pressure air to clean internal windings. Parts inside the control console should be cleaned and inspected at this time as well.

Finally, have the insulation resistance of stator and rotor windings checked. If insulation resistances are excessively low, the generator may require drying.

‹BATTERY

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 charg- ing. The slightest spark can ignite the gas and cause an explosion. Such an explosion can shat- ter the battery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smok- ing, open flame, sparks or any spark producing tools or equipment near the battery.

Battery electrolyte fluid is an extremely corro- sive 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 fluid is spilled, flush the affected area immediately with clear water.

All lead-acid storage batteries discharge when not in use. Refer to specific instructions and warnings that accompany the battery. If such information is not available, observe the following precautions when handling a battery:

•DO NOT use jumper cables and a booster battery to crank or start the generator engine.

•DO NOT recharge a weak battery while it is installed in the generator. Remove battery from generator and recharge in a well-ventilated area, away from fuel vapors, sparks, heat or flames.

•Battery electrolyte fluid is an extremely caustic sulfuric solution that can cause severe burns. DO NOT permit fluid to contact eyes, skin, clothing, painted surfaces, wiring insulation, etc. If any bat- tery fluid is spilled, flush the affected area with clear water immediately.

•Always wear safety glasses, rubber apron and gloves when handling a battery.

•Batteries give off explosive hydrogen gas while charging. The gas can form an explosive mixture around the battery for several hours after charging. Any spark, heat or flames can ignite the gas and cause an explosion which can shatter the battery, causing blindness or other serious injury.

‹BATTERY MAINTENANCE

The battery should be inspected per Section 4.7, Scheduled Maintenance. The following procedure should be followed for inspection:

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

12/05 B .Rev Maint006

Do not use any jumper cables or booster battery 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 120VAC power supply to the battery is turned OFF, or sparking may occur at the bat- tery posts as the cables are attached and cause an explosion.

‹BATTERY REPLACEMENT

When replacing batteries, use the same number and the type of battery that follows:

 

BCI Group No.

CCA

 

 

26

525 @ 0 deg. F

 

 

 

 

 

NOTE:

The BCI number should be located directly on the battery.
