4. Turn on 750/752 Tracker and check four-digit code.
If codes on tracker and display match, thrust and
rotation hydraulics on the drilling unit are enabled.
If codes on tracker and display do not match, adjust
tracker code:
• Press and hold fore/aft/left/right button while
making the following adjustments.
• Use ON/OFF to advance first two digits (1). Use
DEPTH to lower first two digits.
• Use up arrow to advance last two digits (2). Use
down arrow to lower last two digits.
• Press and hold each button to advance or lower
value quickly.
• To start sending code from the tracker to the
display, press and hold fore/aft/left/right button

on the drilling unit are now enabled.
5.
Remove tracker control key (shown) from set-up
console at rear of drilling unit. Keep in tracker
operator’s possession.
6. Drill and track bore.
Troubleshooting Tip: If thrust and rotation are not
enabled:
• Check whether the green tracker control light
located on drilling unit anchoring console is on. If it
is, communication has probably stopped between
tracker and display, or tracker is set to incorrect
code.
• If communication cannot be restored, install tracker
control key (shown) in drilling unit and rotate
clockwise. Green tracker control light located on
anchoring console will go off. Thrust and rotation
will function.
NOTICE: Tracker operator cannot disable thrust and
rotation from tracker if tracker control key (shown) is
installed in drilling unit and turned to the disable
position. See “Tracker control key” on page 23 for more
information.
