Air Filter Maintenance
Routine maintenance of the air filter helps maintain proper airflow to the carburetor. Occasionally verify that the air filter is free of excessive dirt. The
air filter will require more frequent cleaning when the generator is operating in extremely dusty areas.
To clean the air filter, remove the foam filter element from the generator and wash it in warm water and household dish detergent. Thoroughly rinse
and dry. Pour a little amount of motor oil onto the filter, ring out ALL excess oil, and reinstall the foam filter element in the generator.
Unscrew the bolts, or unsnap the clips at the top and bottom of the air filter cover, located below the choke lever, to access the foam filter element.
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.
2.
Unscrew the spark plug from the generator by using the spark plug wrench.
3.
Visually inspect the spark plug. If it is cracked and/or chipped, replace with a new spark plug. An E7TC spark plug, such as
NGK
BP6HS
, 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 9.)
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 the generator.
7.
Replace the spark plug cap.

To store this generator for extended time, drain gasoline out from the carburetor AND fuel tank.
To drain gasoline from the generator:
1. Turn the fuel valve to the
“
OFF
”
position and let the engine run until it stops.
2.
Remove the fuel filter cup.
3.
Empty the fuel filter cup of any fuel.
4.
Place a container underneath this generator to catch gasoline as it drains.
5.
Turn the fuel valve to the
“
ON
”
position and allow all gasoline to drain out.
6.
Turn the fuel valve to the
“
OFF
”
position.
7.
Replace the fuel filter cup.
8.
Store the drained gasoline in a suitable place.
To store this generator for extended time, the fuel needs to be drained out from the carburetor completely.
To drain the gasoline from the carburetor, turn the fuel valve to the
“
OFF
”
position while the engine is running. The generator will shut down when
all the gasoline in the carburetor has been used up, OR, unscrew the draining bolt on the bottom side of the carburetor to drain all gasoline out
completely.
