    CASING PHASE TOOLING STANDARD PILOT READY HEAD- Used in ground conditions that require the casing to be overcut. Recommended with a drift ring. Best practice to shim the inside of the casing were the ring makes contact in order to center the head. Shock rod and swivel should be used to keep the pilot string form rotating.

    Set Up PATHFINDER SET UP Set up a stringline above the bore pit with the transit. On the proposed bore path. Instal stakes at eather end deep enough to strech the string tight. Do this with the ability to have the sring removed as equipment is set in the pit.
  • Page 20 Aline the front and rear of the track by dropping plumbob’s down from the string line. The string must match the centerline of the track. Adjust the track as needed and retighten the track jack. If your not using a track jack you can weld the side of the track off to the trench box. If your in a slopped pit then you can acheve this by driving long beams into the ground and weld them off to the track.

  • Page 25 Place into the vertical stand 5. Place the monitor case on top of the fixture located above the operator’s station. Use the supplied rubber buggies to secure the monitor to the fixture. Open the lid. The lid has a self-locking gas strut to keep it open.
  • Page 26 6. Make two monitor electrical connections to the supplied junction box. NOTE- It’s a good practice to secure the junction box down to avoid dropping it and damaging connectors. Cables will only connect one way. Set Up...
  • Page 27 7. Make all connections at the theodolite. 8. Turn on the monitor by placing the rocker switch to the “Power” position. NOTE- The monitor is a complete touch screen computer. Take caution when handling it. The unit has a built in heater that will automatically turn on if working in a cold environment.
  • Page 28 9. Use the vertical adjustment to place the pivot point of the theodolite on the centerline of the boring machine. An easy way to do this is to place a level or a straight edge across the top of the thrust frame then measure from the bottom of the level to the pivot point of the theodolite.
  • Page 29 11. Use the horizontal adjustment and a plum bob hung from the string line to center the theodolite with the bore path. Lock the horizontal adjustment down by tightening the thumb screw. 12. Check the bubble levels again if not level redo steps 10 and 11. Set Up...
  • Page 30 13. Use the peep sight mounted on top of the theodolite and right, front knob on the base of the theodolite to spin the theodolite and align to the previous installed string line. The farther away the string is from the theodolite the more accurate the camera will be. PEEP SIGHT Lock this adjustment down by tightening the larger portion of the adjustment knob.
  • Page 31 14. Turn the theodolite on by gently pressing the yellow power button on the lower right side of the display. 15. Now that the theodolite is completely lined up press the “0 SET” button twice to set the horizontal readout to 0 as shown in the photo above. If the numbers switch from 0 to any other number you know the horizontal alignment is off and needs adjusted back to 0.
  • Page 32 16. Setting the grade. Gently push the “V/%” button on the display. This will flip the readout from percent to degrees. Choose the appropriate setting. NOTE- The theodolite will not display the grade if the unit is not level. 17. Use the rear knob above the display to set the grade. Lock this adjustment down by tightening the larger portion of the adjustment knob.
  • Page 33 The theodolite is now set up and ready to install the pilot string. The target may appear to be way off line and grade. This is common and must be fixed by penetrating the ground and steering the target to the crosshairs on the monitor.
  • Page 34 19. Using the magnifier on the lower tool bar to enlarged the image up to600%. This is helpful when piloting for a long distance. 20. Shut down the monitor by clicking the windows icon and selecting “Shut down”. When the unit turns off it’s safe to switch the rocker switch to the off position.

  • Page 36: Operation

    BASIC OPERATION 1- Using the thrust lever, complely retarcted the carriage to load a rod. The rod support will rase up into position automaticly. When setting a rod in place be sure to push the rod forward into the femail end of the previous rod then rest it on the rod support. Prep the threads with copper cote antiseaze/ lubercant.
  • Page 37 3- Rotate clockwise to make up the tool joints on both ends. It’s always best to make up each tool joint tight enough that reverse rotation can be made without loosening a tool joint downhole. 4- Use the float on the piston end of the cylinders during the thread up process. This will greatly reduce the wear on the threads.
  • Page 38 5- Rotate and thrust independently to steer the pilot into the ground. Excessive rotation will create heat and sometimes drop the pilot between the machine and the target housing. Causing loss of the top of the target (sag) as it’s displayed on the monitor. LINE AND GRADE CROSSHAIRS...
  • Page 39 7- After you’ve successfully inserted the rod into the ground. Close the front clamp and reverse rotate until the joint is unthreaded. Use the float from step 4. 8- Carefully close the rear clamp making sure not to bite onto the mail threads. Break the tool joint at the spindle and unthread, again paying attention to the position of the float.

  • Page 40: Lubrication

    LUBERCATION Use a Barbco Bentonite Pump to mix and pump fluid to reduce torque as needed. Excessive pumping will sometimes drop the pilot between the machine and the target housing. Causing loss of the top of the target (sag) as it’s displayed on the monitor. Make sure to flush out the rod when the pilots complete.
