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).

Note: Brake must be engaged, motion control levers out (neutral lock position) and PTO switch “OFF” to start engine. (It is not necessary for the operator to be in the seat to start the engine.)

Drive wheel release valves are used to release the hydrostatic drive system to allow the machine to be pushed without the engine running. Unhook seat latch and tilt seat up to gain access to pumps.

With a 5/8 inch wrench, turn both valves one turn counterclockwise to release drive system. Turn clockwise to reset system. Do Not overtighten. Do

Not tow machine.

Hour Meter

Located on the right fuel tank.

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.

Fuel Shut-Off Valve

Located directly below the right side of console, next to the cubby.

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.

The valve has three positions, each position made in 1/4 turn increments.

Tracking Adjustment Knob

Located under the seat on the LH pump control link.

Rotating this knob allows fine tuning adjustments so that the machine tracks straight with the drive levers in the full forward position.

Stop machine and wait for all moving parts to stop. Engage park brake. Unhook seat latch and tilt seat forward to gain access to the tracking knob. Rotate the knob clockwise (as viewed from the rear of the machine) to cause the machine to track more to the right and counterclockwise to cause the machine to track more to the left. Adjust in quarter-turn increments until the machine tracks straight. Check that the machine does not creep when in neutral with the park brake disengaged.

Important: Do Not rotate the knob too far, as this may cause the machine to creep in neutral. Refer to the Motion Control Linkage Adjustment section in Maintenance.

PTO Engagement Switch

Located on right fuel tank.

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.

Fuel Gauge

Located on the left fuel tank.

The fuel gauge monitors the amount of fuel in the left tank only. Use the fuel from the right fuel tank first. When the right fuel tank is empty, switch to the left fuel tank. Fuel gauge will monitor the remaining fuel.

Coolant Temperature Gauge

Located at the front of the left fuel tank.

The coolant temperature gauge monitors the temperature of the engine coolant. An engine overheating condition is indicated by the red area on the gauge and an alarm will sound. Refer to the Warning Buzzer in the Troubleshooting section.

Drive Wheel Release Valves

Located on the top right front corner of hydrostatic pumps.

Voltmeter

Located next to the Coolant Temperature Gauge at the front of the left fuel tank.
