‹4.5.11 CHANGING THE ENGINE AIR CLEANER

To replace the engine air cleaner, (part number 0A4637), remove the air cleaner cover and replace the air filter making sure it is positioned properly before reattaching the cover.

See the “Service Schedule,” Section 6, for air cleaner maintenance.

‹4.5.12 SPARK PLUGS

Reset the spark plug gap or replace the spark plugs as necessary. See Section 6.

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 com- mercial 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 6, for recommended inspection.

3.Check the spark plug gap using a wire feeler gauge. Adjust the gap to 1.01 mm (0.040 inch) by carefully bending the ground electrode (Figure 4.3).

‹4.5.13 COOLANT CHANGE

Every year, have an authorized service dealer drain, flush and refill the cooling system. See SPECIFICA- TIONS (Section 1.10) for cooling system recommen- dations.

4.6MISCELLANEOUS MAINTENANCE

‹4.6.1 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 deal- er 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.

‹4.6.2 BATTERY

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.
