Press both the bump up and bump down buttons for one second and release, the instrument cluster should read 'CAL THROTTLE' or 'CAL FTR'. Smoothly move the brake pedal from release to applied position two-to-four times. When the machine being calibrated is properly displayed, press both the bump up and bump down buttons for one second and release, the instrument cluster should read 'CAL BRAKE' or 'CAL BRK'. The improper horsepower range selection will cause the calibration to be incorrect and machine functions will be impaired. If needed, use the bump up/down buttons to select the machine horsepower rating that is being calibrated, 70-80 (650K / D75), 80-90 (750K / D85), or 90-100 (850K / D95). Start the engine and continue to hold the bump up and bump down buttons until 'HP XX-XX' is displayed. Push and hold the bump up and bump down buttons on the directional control handle. I don't believe the dealer will be of much value at this point, as you can test everything you need to through the cluster. There is no linkages to the hydrostatic pumps, as they are controlled by solenoids. Joysticks can not be tested by the dealer, unless they have a machine in the yard to plug it into.

The brake potentiometer output (number 521 wire) must be set so that the voltage is 2.75 volts to 4.5 volts with the pedal released (in the full UP position), and 0.5 to 2.25 volts with the pedal fully depressed.Īfter you have done this, perform a calibration in the dash.Īssuming my statements are correct, your joystick is not your issue.
The potentiometer often sticks.Ĭheck the brake potentiometer output.

You will not get a fault code if the failure is within the accepted voltage range. Your issue is present in forwards and reverse.Īssuming the above statements are correct, it sounds like your brake potentiometer is likely your issue. The travel speed % properly shows in the cluster.Ĥ.
The travel speed of the machine will increase and decrease with the rabbit and turtle buttons on the joystick.ģ. 1.Your max travel speed is relatively low, as compared to last year or previous experience.Ģ.
