engine to cool for several minutes.
2. Release the four clips then remove the air filter cover.

ENGINE OIL LEVEL CHECK
Avoid skin contact with engine oil. Wear protective
clothing and equipment. Wash all exposed skin with
soap and water.
Always use the specified engine oil. Failure to use the
specified engine oil can cause accelerated wear and/or
shorten the life of the engine.
When using the generator in dusty conditions or in
extremely hot weather, change the oil more frequently.
Ambient air temperature will affect engine oil performance.
Change the type of engine oil used based on weather
conditions.
