Bucket calibration

All buckets are calibrated using the CAT interface. You cannot calibrate them using the Topcon 3D-MC software. Contact your local CAT dealer for information on the bucket calibration procedure.
The excavator operator must cycle the cab safety lever after changing the attachment on the CAT menu. Manually cycling the cab lever is the only way to change the attachment in 3D-MC.
