The hour meter is connected to a pressure switch installed in the engine block and it records the number of hours that the engine has run. If the ignition switch is left on without engine running, hour meter will not run.

Note: This switch is not a low oil sensor and will not alert the operator if the engine oil is low.

The hydraulic lift switch is used to raise and lower the mower deck.

Push the front portion of the hydraulic lift switch down to raise the mower deck to the desired height.

Push the rear portion of the hydraulic lift switch down to lower the mower deck to the desired height.

Fuel Shut-Off Valve

Located in fuel line by fuel tank and fuel filter.

The fuel shut-off valve is used to shut off the fuel when the machine will not be used for a few days, during transport to and from the jobsite, and when parked inside a building.

Rotate the valve 1/4 turn clockwise to shut off fuel. Rotate the valve 1/4 turn counterclockwise to turn on fuel.

Fuel Gauge

Located at the rear of the right fuel tank.

The fuel gauge monitors the amount of fuel in the right fuel tank only. The left tank does not hold fuel.

Pre-Start

Fill fuel tanks. For best results use only clean, fresh regular grade unleaded gasoline with an octane rating of 87 or higher. Regular grade leaded gasoline may also be used; however, combustion chamber and cylinder head will require more frequent service. See Engine Owner’s Manual.

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.
