b. Blade Pro® Motor Grader Control System Valve Calibration.
Valve calibration is required whenever you change hoses, lift cylinders, or any other
repairs to the hydraulic system. Failure to perform valve calibration could result in
improper equipment performance or damage to equipment.
Perform the sensor calibration procedures prior to performing the valve calibration
procedures. Failure to comply could result in improper 130G Grader performance.
Operate the machine until the hydraulic oil has reached normal operating temperature
before starting the valve calibration. Failure to comply could result in improper Blade
Pro® Motor Grader Control System performance.
Blade Pro® Setup will be displayed across both windows for a few seconds, then
REFERENCE and 0.00 will be displayed.
Ensure 130G Grader is on level ground, A-frame is centered, and blade is perpendicular
Valve calibration and sensor calibration settings are specific for the make, model,
bumper number, and serial number once calibration is completed.
