Header System Calibration; Calibrating Knife Drive On Harvest Performance Tracker Display - MacDon M1170 Unloading And Assembly Instructions

5.1.6 Header System Calibration

The Harvest Performance Tracker (HPT) recognizes when a header is attached to the windrower and determines which
systems will require calibration.
The following sensors may require calibration, depending on the type of header attached to the windrower:
• Header height
• Header angle
• Header float left
• Header float right
Recalibration is required in the following circumstances:
• The HPT is replaced
• A position sensor is replaced
• Sensor readouts are erratic
• A pump has been replaced
• A new header type or attachment is connected to the windrower

Calibrating Knife Drive on Harvest Performance Tracker Display

When a header is attached to the windrower, the windrower's Harvest Performance Tracker (HPT) will recognize the
header ID and choose the appropriate settings for that header. Before it can be operated, however, the header's knife drive
must be calibrated to ensure that the knife drive pump output is accurate.
DANGER
Ensure that all bystanders have cleared the area.
1. Start the engine.
2. Press soft key 5 (A) to open the Harvest Performance
Tracker (HPT) main menu.
NOTE:
Calibrations MUST be performed with the engine
running. Some calibrations will not be available with the
engine off.
3. Use HPT scroll knob (B) or the ground speed lever (GSL)
scroll wheel (not shown) to highlight SETTINGS icon (C).
4. Press HPT scroll knob (B) or the GSL SELECT button (not
