CAUTION: A mixture of alcohol (ethanol or methanol) and gasoline (called gasohol), will attract moisture and cause acid deposits during storage. While the unit is in storage, the acids in the fuel can damage the fuel system.

To prevent engine problems with the fuel system, empty the fuel system before storage of 30 days or longer as follows.

1.Drain the fuel tank.

2.Start the engine. Let the engine run until the fuel lines and the carburetor are empty.

For your protection, always make sure this system operates correctly.

4.Turn the ignition key to the START position. Release the key when the engine starts.

NOTE: If the engine does not start after four or five tries, see the TROUBLE SHOOTING CHART.

5.Slowly move the throttle control to the SLOW position.
