3.5CHECKING THE ENGINE

SPARK PLUG

Clean the spark plug and reset the spark plug gap every 100 hours of operation.

1.Clean the area around the base of the spark plug to keep dirt and debris out of the engine. Remove the spark plug and check the condition. Replace the spark plug if worn or if reuse is questionable.

2.Clean spark plug by scraping or washing using a wire brush and commercial solvent. Do not blast the spark plug to clean.

3.Check the spark plug gap using a wire feeler gauge. Adjust the gap to 0.030 inch (0.76 mm) by carefully bending the ground electrode (Figure 3.4).

Figure 3.4 – Setting the Spark Plug Gap

Sparking can occur if the wire terminal does

!not fit firmly on the spark plug terminal end. If necessary, re-form the wire terminal to obtain a tight fit.

3.6FUEL FILTER

Remove and replace the fuel filter (Figure 3.5) once each year or every 400 hours of operation, whichever comes first. Fuel filter is removed with a 15/16” deep well socket.

3.7CLEAN SPARK ARRESTOR

The engine exhaust muffler has a spark arrestor screen. Inspect and clean the screen every 50 hours of operation or once each year, whichever comes first.

NOTE:

If you use your generator on any forest-covered, brush-covered or grass-covered unimproved land, it must equipped with a spark arrestor. The spark arrestor must be maintained in good condition by the owner/operator.

Clean and inspect the spark arrestor as follows:

•Remove the screen retaining bracket by removing the screw.

•Slide the spark arrestor screen out from the tail pipe.

•Inspect screen and replace if torn, perforated or otherwise damaged. DO NOT USE a defective screen. If screen is not damaged, clean it with com- mercial solvent.

•Replace the screen and the retaining bracket.
