Operation

The hour meter records the number of hours that the engine has run.

2.Low voltage indicator light

3.Hour/Voltage display

The hour meter is recording when the decimal point is flashing in Hour/Voltage display.

Hours are displayed when the key is off or when the machine is running.

Note: If the ignition key is turned to the “ON” position for a few seconds before cranking the engine, the battery voltage will display in the area where the hours are normally displayed.

Note: The LCD indicators appear when each control meets the “safe to start” mode (e.g. the indicator turns on when the operator is in the seat.)

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

Fuel Shut-Off Valve

The valve is located in the fuel line midway between the fuel tank and the engine behind the seat.

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.

Drive Wheel Release Levers

Located at the rear of the mainframe.

Drive wheel release levers are used to release the hydrostatic drive system to allow the machine to be pushed without the engine running.

Pull each lever rearward and outward to lock. Pull each lever inward and push forward to reset. Do Not tow machine.

PTO Engagement Switch

Located right of center on the console (left side of ignition switch).

Switch must be pulled out to the “ROTATE” position to engage the blades. Switch is pushed in to the “STOP” position to stop the blades.

The LCD indicator will appear when the PTO switch is disengaged (see Figure 6).

Low Voltage Indicator

Located on the center console in the message display (see Figure 6).

A low voltage condition (less than 12.3 volts) exists when the low voltage indicator light appears on the message display while the engine is running.

If the ignition key is turned to the “ON” position for a few seconds before cranking the engine, the battery voltage will display in the area where the hours are normally displayed.

Note: The indicator normally appears when the engine is off and the key switch is turned to the “ON” position.

Pre-Start

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

Important: Never use methanol, gasoline containing methanol, gasohol containing more than 10% ethanol, premium gasoline, or white gas because the fuel system could be damaged.

Do Not add oil to gasoline.

Do Not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system (if equipped).
