ENGINE AIR FILTER CHANGE

The generator engine is equipped with a dry element air filter to block particles in the combustion air from getting into the engine and causing excessive engine wear. Over time this dirt builds-up on the filter, restricting the amount of combustion air available to the engine, in turn leading to a loss of generator power output. To avoid these problems, periodic replacement of the engine air filter is recommended at the intervals outline in the service schedule table on page 25. To change the air filter, follow the listed steps.

CAUTION

•Never run this equipment without the complete air cleaner system installed on the engine. Failure to do so will result in premature engine wear and significantly reduced engine life.

1.Locate the air filter cover snaps as shown in Fig. D and pull them upward to release the cleaner cover.

2.Remove the air cleaner cover to access the filter elements, then remove the dirty paper filter element and foam element.

3.Carefully wipe the inside of the air cleaner housing and lid clean with a clean, lint-free rag, taking care not to knock dirt into the engine intake opening.

4.Wash the foam element in warm soapy water, rinse, and allow to dry completely. DO NOT oil the foam element.

5.Place the new paper filter element into the air cleaner housing, then re-install the foam filter.

6.Complete the replacement by putting the air cleaner cover back in position and snapping the cover snap closed.

BATTERY MAINTENANCE

WARNING

•Read and understand all warnings and cautions on page 16 of this manual before preceding with any battery maintenance.

Correctly maintaining the battery at regular intervals is vital to ensure consistent engine starting. Poorly maintained batteries loose charge over time and may not provide enough power to crank the engine fast enough for reliable starts. The steps below are suggested to care for the battery and charger.

1.Access the battery (A) by removing the 3 access panel screws (B) shown in Fig E using a 5/16" wrench. The hinge panel (C) is then rotated to expose the battery.

2.Keep the battery cable clamps at the battery posts tight and free of corrosion. Replace the battery cables if cracks are found in the clamps.

3.Check and adjust the level of battery electrolyte according to the battery manufacturer’s instructions if not using a “maintenance-free” battery. If electrolyte is low, add only distilled water to the battery. Do not add tap water to the battery.

4.Use a battery hydrometer to check the condition of the electrolyte in each of the battery cells. Follow the instructions provided by the hydrometer manufacturer to assess the quality of the battery.
