Engine Operation
Before Starting the Engine
Check the Oil
NOTE: The engine was shipped from the factory filled with oil. Check the level of the oil. Add oil as needed. See the engine manufacturer’s instructions for the type of gasoline and oil to use.
1.Make sure the unit is level.
NOTE: Do not check the level of the oil while the engine runs.
2.Check the oil. Follow the procedure in the engine manufacturer’s instructions.
3.If necessary, add oil until the oil reaches the FULL mark on the dipstick. The quantity of oil needed from ADD to FULL is shown on the dipstick. Do not add too much oil.
Add Gasoline
WARNING: Always use a safety gasoline container. Do not smoke when adding gasoline to the fuel tank. Do not add gasoline when you are inside an enclosure. Before you add gasoline, stop the engine and let the engine cool for several minutes.
Fill the fuel tank with regular unleaded gasoline. Do not use premium unleaded gasoline. Make sure the gasoline is fresh and clean. Leaded gasoline will increase deposits and shorten the life of the valves.

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.
3.After storage, make sure you use fresh fuel. See the storage instructions for additional information.

How to Start the Engine
WARNING: The electrical system has an operator presence system that includes a sensor switch for the seat. These components tell the electrical system if the operator is sitting on the seat. This system will stop the engine when the operator leaves the seat. For your protection, always make sure this system operates correctly.
NOTE: The engine will not start unless you depress the brake pedal or engage the parking brake and disengage the blades.
1.Push the brake pedal completely forward. Keep your foot on the pedal.
2.Make sure the blades are disengaged.
3.Move the throttle control completely forward to the FAST position.
