Manual Calibration Procedure
N OT E
Calibrations can be automatic or manual.
If equipped with linkage position sensors, calibraions for lift and tilt valves will be automatic. If
not equipped with linkage position sensors, calibration will be manual. Auxiliary control is a man-
ual calibration. However, the auxiliary control calibration is still described in section for auto-
matic calibration since this is normal state for calibration of auxiliary control. Manual calibration
starts same way as automatic calibration. MSD will automatically display appropriate calibra-
Manual calibration requires operator input todetermine movement of linkage while automatic
calibration determines movement with help of linkage position sensors.
Procedure for calibrating current fow to solenoid valves in main control valve is automatic cali-
bration. Solenoids for implement control valve are calibrated through MSD.
Ensure there are no active diagnotic codes for hardware faults.
Joystick sensors are factory calibrated and shoud not require calibration. However, calibration
may be necessary if problems exist activating detents.
Up arrow refers to LOWER position. Down arro refers to RAISE position. Right arrow refers
to DUMP position. Left arrow refers to TILT BACK position.
For auxiliary control, up arrow refers to au iliary lever in FORWARD position. Down arrow
refers to auxiliary lever in REARWARD position.
For additional information on joystick control, refer to TM 5-3805-291-10.
