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
in SETUP - TRACKING - PAGE 2. See
implement offset section. 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.
