Remove Pullback Device
The pullback device can be removed when the last pipe is on the frame. It can also be removed when a
target pit along the bore path has been reached. Remaining pipe is then pulled back and removed.
1. Turn off drilling fluid.
2. Move drilling unit throttle control until engine is at low throttle.
3. Turn drilling unit engine off.
4. Use tracker control to verify that unit is turned off.
5. Clean pullback device.
6. Use quick wrench to remove pullback device. See “Quick Wrench” on page 107.
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.
