7. Continue to move the drill carriage slowly down the
frame until the male threads on the pipe are under
the thread-joint-compound applicator and apply
thread-joint compound to the threads.
8. Release and retract the pipe gripper, rotating it all the
way out to the third row of pipes.
Important: Ensure that you fully retract the
pipe gripper and rotate it all the way out or the
carriage may collide with the gripper, damaging
the machine.
9. Continue to rotate the drive spindle clockwise, until
the male pipe threads are fully seated into the sonde
housing or the lead bar.
Note: Torque the threads to 2305 N-m (1700 ft-lb).
Installing the Drill Head
1. Using the exit-side-lockout transmitter, enable the exit
side lockout.
WARNING
If the drill rotates or extends while you or
others are manually working on the drill bit or
pipe in front of the machine, the worker could
get caught in the bit or pipe causing serious
injury, amputation, or death.
• Enable the exit-side lockout on the
exit-side-lockout transmitter before
approaching the dill bit or pipe when
attached to the machine. This will disable
the drill carriage.
• Do not wear loose clothing or jewelry when
working on a drill bit or pipe attached to
the machine. Tie long hair up.
2. Hand thread the lead bar onto the pipe threads then
clear away from the front of the machine.

3. When the area is clear of people, disable the exit-side
lockout using the exit-side-lockout transmitter
(the OK-to-Drill light on the control panel should
illuminate); press the exit-side-lockout, reset switch on
the control panel.
4. Pull the drill pipe and lead bar back through the pipe
guide and into the wrenches, aligning the thickened
upper joint of the lead bar with the upper wrench
(Figure
30).
Important: Do not clamp the wrench on the body
of a pipe or it may damage the pipe. Grip the pipes
on the shoulder near the joint.

5. Using the upper wrench, clamp the lead bar and tighten
it to full machine torque.
6. Using the exit-side-lockout transmitter, enable the
exit-side lockout.
7. Double check the drill head and bit to ensure that the
fluid ports are clean and free from obstructions.
8. Install the drill head onto the end of the lead bar as
directed by the drill head manufacturer, then clear away
from the front of the machine.
Important: Do not pull the drill head into the
pipe guide or you may damage the machine or the
drill head.
Boring the Entry Shaft
The first boring step is to create the entry shaft. In this step,
you push and bore the drill bit and first few pipes into the
ground at an angle from 0 to 16 degrees (with the tracks flat
on the ground) until you reach the desired depth of your
installation.
Important: Drill and ream in a clockwise rotation.
If you use a counterclockwise rotation the pipe will
