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 operating this generator in extremely dusty areas.
To clean air filter, remove from generator. Wash in kerosene. Pour motor oil on filter, squeeze out excess oil and reinstall in the generator.
