Surface Drill Head
1. Guide drill head to target pit or up through surface. Make all bends gradual. See “Recommended Bend
Limits” on page 56.
2. Clean area around exit point.
3. Turn fluid flow control to off position as soon as drill head emerges.
4. Allow tracker operator to turn off tracker to disable drilling unit thrust/pullback and rotation hydraulics.
Tracker operator waits for green light to enter pit and change tools.
5. Clean drill head especially around threads.
6. Disconnect EZ-Connect joint or use quick wrench to remove drill head. Keep threads clean. See
“Quick Wrench” on page 115.
Moving tools will injure or kill. Shut off drill string power when anyone can
be struck by moving or thrown tools. Never use pipe wrenches on drill string.
Turning shaft will kill you or crush arm or leg. Stay away.
NOTICE:
• Tracker operator and drill operator should maintain two-way communication.
• Keep everyone clear of the exposed drill string.
• No one should enter pit until clear communication is given by the drill operator that the drill unit is
shut down. Do not enter pit until tracker control is turned off and green light on drill unit is lit.
• Drill operator should be instructed to discontinue drill string rotation as soon as drill bit exits the
bore. Use thrust only to extend drill string beyond exit hole.
