Tracker Control
Overview
This mode allows the 750 Tracker operator to disable hydraulic power to drilling unit thrust and rotation.
Use tracker control any time you change downhole tools or during other times when the drill string is
exposed. Tracker control works by stopping communication between the tracker and the display. When
this happens, the green tracker control light on the drilling unit comes on and thrust and rotation are
disabled.
Operation

NOTICE: This mode does not disable thrust and rotation immediately. Functions are disabled within 16
seconds.
