Air Filter Maintenance; Spark Plug Maintenance - Sportsman GEN4000TRI Instruction Manual

Air Filter Maintenance

Occasionally verify that the air filter is free of excessive dirt. The air filter will require more frequent cleaning when operating this generator in extremely
dusty areas.
1. Unhinge the clasps at the top and bottom of the air filter cover as shown in Figure 15.
2. Remove the sponge-like elements from the casing.
3. Wipe the dirt from inside the empty air filter casing.
4. Wash the sponge-like elements in household detergent and warm water. Do not use gasoline or a flammable solvent.
5. Allow the sponge-like elements to dry thoroughly.
6. Drip several drips of engine oil onto the sponge-like elements. Squeeze out any excess oil. The engine will smoke during initial startup if too much
oil is left in the air filter.
7. Replace the sponge-like elements in the air filter casing (the fine element first) and replace the cover.

Spark Plug Maintenance

The spark plug is essential for proper engine operation. The spark plug should be intact, free of deposits, and properly gapped. A bad or incorrectly
installed spark plug can cause engine damage. To inspect the spark plug:
1. Remove the spark plug by pulling on the spark plug cap. Fig 16
2. Unscrew the spark plug from this generator by using the included spark plug wrench.
3. Visually inspect the spark plug. If it is cracked and/or chipped, discard and install a new spark plug. A F7RTC spark plug, such as
NGK BPR6ES is recommended.
4. Measure the spark plug electrode gap with a gauge. The gap should be 0.020-0.028in (0.5 -0.7mm). (See Figure 17.)
5. If re-using the spark plug, use a wire brush to clean any dirt from around the spark plug base and then re-gap the spark plug.
6. Screw the spark plug back into place on this generator by using the included spark plug wrench.
7. Replace the spark plug cap.
