4. Turn on 750 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 and
press MODE. Thrust and rotation hydraulics 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. Green tracker control light
located on anchoring console will go
off. Thrust and rotation will function.
