Calibration Surface
IMPORTANT: Vehicle must be on a hard, flat level
surface for calibration. If TCM is not
calibrated on a level surface or TCM
mounting angle is not level in relation
to vehicle angle (StarFire mounting
bracket or vehicle cab being slightly
offset, uneven tire pressures from one
side to other, etc.) operator may see
offset during operation. This offset
could look like a consistent skip (A) or
overlap (B) in pass-to-pass operation.
To eliminate offset, re-calibrate on a
level surface, drive down a pass, turn
around and drive down same pass in
opposite direction. If vehicle does not
follow same pass, measure offset
distance and enter in implement offset.
After initial calibration of TCM, it is not
necessary to calibrate again unless
TCM angle in relation to vehicle has
changed. For example, tire pressure has
been lowered on one side of vehicle
causing vehicle angle in relation to
ground to change.
Calibration Procedure:
1. Press CALIBRATION button.
2. Park vehicle on a hard, level surface and come to a
complete stop (cab is not rocking).
3. Press ENTER button.
4. Calibrating Status bar will appear. Once status reaches
100% it will automatically advance.
5. Turn vehicle 180 degrees to face opposite direction.
Ensure that tires are in proper location for fixed or
floating front axle and vehicle has come to a complete
stop (cab is not rocking).
6. Press ENTER CALIBRATION button.
7. Calibrating Status bar will appear. Once status reaches
100% it will automatically advance.
8. Once finished, a calibration value will be displayed. 0
degree calibration value is the difference between
factory calibration value and actual calibration value
which was just determined.
