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). 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 carriage 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 carriage will go off. Thrust
and rotation will function.
