across the terminals in the connector of the wiring harness.
3.Start the engine.
4.Run the unit at least 5 minutes with the speed control lever at full forward speed to bring hydraulic system oil up to operating temperature. Return speed control lever to neutral (full rear) position.
5.To obtain the neutral position, adjust the left and right pump control rod linkages that connect the steering control to the pump control arms until the wheels stop, or creep slightly in reverse.
6.Adjust the left pump linkage by rotating the tracking adjustment knob.
7.Adjust the right pump linkage by using a wrench to turn the double nuts on the assembly (see Figure 17)
Set forward stop bolt:
1.Remove seat deck (with seat attached) to obtain a clear view of the steering control shaft to complete this adjustment.
2.Push the speed control lever forward to full forward speed position.
3.If either steering control lever surface does not contact the stop bar at the full forward speed position, adjust the stop bolt until contact occurs (see Figure 18). Once contact occurs, turn the stop bolt one more full turn to prevent bottoming of the hydraulic pump internal stops.
