Controls

Motion Control Levers

The motion control levers located on each side of the console control the forward and reverse motion of the machine.

Moving the levers forward or backward turns the wheel on the same side forward or reverse respectively. Wheel speed is proportional to the amount the lever is moved.

Moving the levers outward from the center position into the T-slot locks them in the neutral position

(Figure 5).

rear, to the detent, will put the choke in the “OFF” position. Do Not run a warm engine with choke in the “ON” position.

The ignition switch is used to start and stop the engine. The 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). Allow the key to return to the “on” position immediately after the engine starts.

LH motion control lever.

The brake lever engages a parking brake on the drive wheels.

Pull the lever up and rearward to engage the brake.

Operation

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.

Align valve handle with the fuel line to open. Rotate

90° to close.

Drive Wheel Release Valves

WARNING

Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury or death.

Stop engine, remove key, allow all the moving parts to stop before accessing the drive wheel release valves.

WARNING

The engine and hydraulic drive units can become very hot. Touching a hot engine or hydraulic drive units can cause severe burns.

Allow the engine and hydraulic drive units to cool completely before accessing the drive wheel release valves.

Located on the left and right sides underneath the engine deck.

During normal operating conditions, the drive wheel release valves are positioned in front of the slots. If the machine has to be pushed by hand, the valves

must be in the “released” position (see Figure 9).
