Tracker Control<br />
4. Turn on 750/752 Tracker and check four-digit code.<br />
If codes on tracker and display match, thrust and<br />
rotation hydraulics on the drilling unit are enabled.<br />
If codes on tracker and display do not match, adjust<br />
tracker code:<br />
• Press and hold fore/aft/left/right button while<br />
making the following adjustments.<br />
• Use ON/OFF to advance first two digits (1). Use<br />
DEPTH to lower first two digits.<br />
• Use up arrow to advance last two digits (2). Use<br />
down arrow to lower last two digits.<br />
• Press and hold each button to advance or lower<br />
value quickly.<br />
• To start sending code from the tracker to the<br />
display, press and hold fore/aft/left/right button<br />
and press MODE. Thrust and rotation hydraulics<br />
on the drilling unit are now enabled.<br />
Troubleshooting Tip: If thrust and<br />
rotation are not enabled:<br />
• Check whether the green tracker<br />
control light located on carriage is on.<br />
If it is, communication has probably<br />
stopped between tracker and display,<br />
or tracker is set to incorrect code.<br />
• If communication cannot be restored,<br />
install tracker control key (shown) in<br />
drilling unit. Green tracker control light<br />
located on carriage will go off. Thrust<br />
and rotation will function.<br />
5. Remove tracker control key (shown). Keep in<br />
tracker operator’s possession.<br />
6. Drill and track bore.<br />
