Pre-Start

Fill fuel tank. For best results use only clean, fresh regular grade unleaded gasoline with an octane rating of 87 or higher.

Do Not add oil to gasoline.

Do Not overfill fuel tank. Never fill the fuel tank so that the fuel level rises above a level that is 1/2 inch (13 mm) below the bottom of the filler neck to allow for fuel expansion and prevent fuel spillage.

Make sure you understand the controls, their locations, their functions, and their safety requirements.

Refer to the Maintenance section and perform all the necessary inspection and maintenance steps.
