Removing Drill Pipes
1. Using the exit-side-lockout transmitter, enable the exit
side lockout.
2. Install a drill-pipe wiper around the pipe and into the
retaining bracket on the front of the machine.
This will remove most of the dirt and mud from the
pipe as you pull it back into the machine, keeping the
machine clean. Contact your Authorized Toro Dealer
to purchase drill-pipe wipers.

3. Disengage the exit-side lockout and reset the system.
4. Begin rotating the drill spindle clockwise and slowly
retract the drill carriage to pull the pipe back into the
machine
5. When the joint between the pipes is centered between
the two wrenches, the drill carriage will stop, and a
green light will illuminate below the spray valve.
6. Close the lower wrench onto the pipe joint.
Note: The drilling fluid will automatically shut off
when you close the lower wrench.
7. Rotate the pipe gripper to the drill frame, extend the
pipe-gripper arms to the pipe, and grip the pipe to
support it.
8. Close the upper wrench onto the pipe joint.
9. Rotate the upper wrench counterclockwise until the
joint is loosened.
10. Release the upper wrench.
11. Pull back the carriage approximately 12.7 mm (0.5
inch).
Note: This will allow the carriage to float, and will not
damage the pipe threads.
12. Rotate the drill spindle counterclockwise moving
rearward slowly until the pipes are separated.

13. Move the drill carriage back until the male-pipe threads
just clear the female end of the lower pipe, then close
the upper wrench onto the shoulder of the pipe, but
not on the threads.
14. Rotate the drill spindle counterclockwise until the
upper-pipe joint is loose but not separated.
15. Release the upper wrench.
Note: The machine will stop at the carriage at the
load position and illuminate another green light under
the spray valve.
16. Rotate the drill spindle counterclockwise moving
rearward slowly until the spindle fully separates from
the pipe.
17. Retract the pipe gripper arms.
18. Rotate the pipe cam to the selected row.
Note: Fill the outside rows first.
19. Release the pipe gripper.
20. Raise the pipe into the pipe basket with the pipe
elevators.
21. Rotate the pipe gripper past 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.
22. Move the drill spindle down the frame under the
thread-joint-compound applicator, and spray the
spindle with thread joint compound.
23. Rotate the drill spindle clockwise and move the carriage
slowly forward to insert the spindle into the female end
of the pipe secured in the lower wrench.
Note: Tighten the joint until you reach no more than
2,304 N-m (1,700 ft-lb).
24. Release the wrench and continue reaming/retraction
as needed.
Removing the Last Pipe and the Reamer
Important: Do not pull the drill head into the pipe
guide or you may damage the machine or the drill head.
1. Using the exit-side-lockout transmitter, enable the exit
side lockout.
2. After the reamer has cleared the ground, if you have
not already done so, disconnect the product being
installed from the reamer.
3. Connect the drilling fluid pump to a source of clean
water.
4. Turn the pump on to flush clean water through the
pump, spindle, and reamer until the water runs clear.
