Correct Dropped Pipe
To return a dropped pipe to the drill string, turn off engine and manually retrieve pipe. Return it to the pipe
box by loading it as a single piece of pipe. See “Add Single Pipe” on page 180.
Correct Misaligned or Jammed Pipe
A pop-up message on the upper display will indicate a misaligned or jammed pipe. Turn off engine and
inspect pipe in active column. If drill pipe is bent, remove it from pipe box and discard.
Rotate Drill Pipe Order
Rotating the drill pipe is a manual process. Rotate drill pipes in the drill string weekly.
Guidelines
• Rotate only as many columns as used on the longest bore of the week. For example, if the longest
bore was 320’ (98 m), then only rotate the four columns used.
• Plan to rotate the pipes during the longest bore of the week.
Procedure
1. Remove rotate pipe retainers (301-8546) from stowed position.
2. Raise pipe until the center of the bottom row of pipe is centered in the bottom slots in the pipe box.
3. Insert rotate pipe retainers into the bottom slot on front and rear of pipe box on the first row of pipe.
4. Secure rotate pipe retainer with lynch pin (p/n 110-228).
5. Adjust row stop to second row of pipe.
6. Operate drill until only one row of pipe remains.
7. Set row stop to first row.
8. Raise pipe lifters to take weight off of rotate pipe retainers.
9. Remove rotate pipe retainers and secure in stowed position.
10. Operate drill until pipe box is empty.
11. Fill box using normal operating procedures.
