    -

Any other condition that may affect safe operation.

 • If an engine problem occurs, have it checked by a qualified service technician before further use.

Do not use damaged equipment.

 • Before each use, make sure the engine’s oil and gas levels are adequate. If necessary, fill the

crankcase until the oil level is even with the oil hill hole and/or fill the fuel tank.

 • Before each use, remove all debris with a soft brush, rag, or vacuum.

 • Lubricate all moving parts using a premium

quality, lightweight machine oil.

Air cleaner service

NOTE: Never run the generator without the air cleaner. Rapid engine wear

             will result.

A dirty air cleaner will restrict air flow to the carburetor. To prevent carburetor malfuncion, service
the air cleaner regularly. Service more frequently when operating the generator in extremely dusty 
areas.

WARNING! Using gasoline or flammable solvent to clean the filter element

               can cause a fire or explosion. Use only soapy water or nonflammable
               solvent.

1. Unsnap the air cleaner cover clips, remove the air
    cleaner cover, and remove the element.

2. Wash the element in a solution of household detergent 
    and warm water, then rinse thoroughly, or wash in
    nonflammable or high flash point solvent. Allow the 
    element to dry thorughly.

3. Soak the element in clean engine oil and squeeze
    out the excess oil. The engine will smoke during
    initial start-up if too much oil is left in the element.

4. Reinstall the air cleaner element and the cover.
