SPARK PLUGS
Reset the spark plug gap or replace the spark plugs as neces- sary.
1.Clean the area around the base of the spark plugs to keep dirt and debris out of the engine. Clean by scraping or washing using a wire brush and commercial solvent. Do not blast the spark plugs to clean.
2.Remove the spark plugs and check the condition. Replace the spark plugs if worn or if reuse is questionable. See the “Service Schedule” section for recommended inspection.
3.Check the spark plug gap using a wire feeler gauge. See the Specifications section for the required spark plug gap.
BATTERY MAINTENANCE
The battery should be inspected per the Service Schedule section. The following procedure should be followed for inspection:
1.Inspect the battery posts and cables for tightness and corro- sion. 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
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 smok- ing, open flame, sparks or any spark producing tools or equipment near the battery.
nBattery 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.
nDo 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.
nBe 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
NOTE:
Unit DOES NOT include battery.
When supplying or replacing the battery, the recommended num- ber and type of battery is listed in the Specifications Section.
NOTE:
The BCI number should be located directly on the battery.
BATTERY FLUID
Check battery electrolyte fluid based on the Service Schedule. Fluid should cover separators in all battery cells. If fluid level is low, add distilled water to cover tops of separators. DO NOT USE TAP WATER IN BATTERY.
CLEANING THE STATIONARY EMERGENCY GENERATOR
Keep the generator as clean and as dry as possible. Dirt and moisture that accumulates on internal generator 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
Once each year have the generator cleaned and inspected by a Service Dealer. That dealer will use dry, low pressure air to clean internal windings.
Finally, have the insulation resistance of stator and rotor windings checked. If insulation resistances are excessively low, the genera- tor may require drying.
