General Inspection Tips

  1. Look for fuel leaks around the fuel tank, fuel hose, fuel valve and carburetor. Close the fuel valve and repair leaks immediately.
  2. Look and listen for exhaust leaks while the engine is running. Have all the leaks repaired before continuing operation.
  3. Check for dirt and debris and clean as necessary.
  4. Check the engine oil level and add oil as necessary.
  5. Do not use gasoline or low flash point solvents for cleaning. They are flammable and could explode under certain conditions.

Cleaning the Air Filter

Using gasoline or other flammable solvents can cause a fire or explosion. Do not operate this product without an air filter.

  1. Rotate the knob counterclockwise to release.
  2. Lift the filter cap to remove from the filter.
  3. Remove the foam filter.
  4. If the foam filter is dirty, clean it in warm soapy water, rinse, and allow it to dry thoroughly, or clean in non-flammable solvent and allow to dry.
  5. Dip the foam filter in clean engine oil, then squeeze out all excess oil. The engine will smoke when started if too much oil is left in the filter.

Changing the Engine Oil

Used motor oil can cause skin irritations if left in long-tern contact with skin. Wash hands thoroughly with soap and water after handling oil. Do not dispose of used oil in drains or on soil. Local service shops provide environmentally-friendly disposal methods.

  1. Stop the engine and remove oil filler cap.
  2. Place a pan under the engine.
  3. Remove the oil drain screw and allow the oil to completely drain into the pan.
  4. Reinstall drain screw before filling the engine with fresh oil. Do not overfill oil reservoir. Use a funnel to prevent spillage.
  5. Reinstall the oil filler cap and tightly fasten
