Pre-Start

Operation

The brake lever engages the park brake on the drive wheels.

Pull the lever up and rearward to engage the brake.

Push the lever forward and down to disengage the brake.

When parking on a steep slope, the wheels must be chocked or blocked in addition to the brake being engaged. The unit must be tied down and brake engaged when transporting.

Park brake must be disengaged to move speed control out of neutral or engine will kill.

Drive Wheel Release Valves

Located on the left rear corner of the hydrostatic pumps.

Drive wheel release valves are used to release the hydro-static drive system to allow the machine to be moved by hand without the engine running.

With a 5/8 wrench, turn both valves one turn counterclockwise to release the drive system.

Turn clockwise to reset the drive system. Do Not overtighten.

Ignition Switch

Located on the left side of the control console.

The ignition switch is used to start and stop the engine. The ignition switch has three positions, “Off ”, “On” and “Start”. Insert key into switch and rotate clockwise to the “On” position. Rotate clockwise to the next position to engage the starter (key must be held against spring pressure in this position). Operator must have speed control lever in neutral, OPC levers depressed and PTO disengaged to start engine. When engine starts, release key.

Hour Meter

Located on the front left hand side of console just above the PTO switch.

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 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.

Fuel Shut-Off Valve

Located in the fuel line midway between the tank and engine.

The fuel shut-off valve is used to shut off the flow of fuel when parking inside a building, during transportation to and from the job sites, and when the machine will not be used for a few days.

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

Tracking Adjustment Knob

Located on the right-hand side of the rear of the fuel tank support.

The knob can be adjusted so that machine will “track” straight ahead with the drive levers released.

PTO Engagement Switch

Switch is located on left side of control console.

The switch must be pulled out to the “Rotate” position to engage the blades. The switch is pushed in to the “Stop” position to stop the blades. Operator must have operator presence control levers depressed when PTO is engaged or engine will stop.

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 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.
