NOTE:
If error message (A) appears when calibrating the knife drive
system, follow the instructions in the message to fix the
error. Press X (B) to exit the message. If the knife
calibration fails:
• Confirm that the engine and hydraulics are at operating
temperature.
• Confirm that the hydraulic system is free of any
restrictions and is in working order.
• Confirm that the throttle is working:
– Check the engine codes to confirm that engine is not
de-rated or throttle-inhibited
– The throttle is controlled via the powertrain’s CAN
network 1. Check the network’s wiring and connectors for an open or intermittent connection
• Confirm that the sensor mounting is secured properly and that the sensor’s gap is set correctly.
• Check the sensor wiring and connectors for an intermittent connection.
• Replace the sensor.
Calibrating Header Position Sensors on Harvest Performance Tracker Display
The header position sensors need to be recalibrated whenever the Harvest Performance Tracker (HPT) is replaced, a
position sensor is replaced, sensor readouts are erratic, a pump has been replaced, or when a new header type or
attachment is connected to the windrower.
DANGER
Never start or move the machine until you are sure that all bystanders have cleared the area.
