JT5 Operator’s <strong>Manual</strong> Prepare - 59 Plan Bore Path Minimum Depth Because you must bend pipe gradually, entry pitch and bend limits determine how deep the pipe will be when it becomes horizontal. This is called the minimum depth. • To reduce minimum depth (D1), reduce entry pitch. This also decreases setback. • To increase minimum depth (D2), increase entry pitch. This also increases setback. Bore Path Calculator Entry pitch, setback, and minimum depth work together with bend limits to determine the bore path. To find the setback (B) and entry pitch (A) that will take you to the desired minimum depth (D), use the chart below. Minimum depth (D) Entry pitch (A) Setback (B) Depth to begin steering (S) 2’ 0" (0.6 m) -18% 17’ 4" (5.3 m) 0’ 11" (0.28 m) 2’ 4" (0.7 m) -20% 18’ 8" (5.7 m) 1’ 0" (0.30 m) 2’ 9" (0.8 m) -22% 19’ 11" (6.1 m) 1’ 1" (0.33 m) 3’ 1" (0.9 m) -24% 21’ 2" (6.5 m) 1’ 2" (0.36 m) 3’ 6" (1.1 m) -26 22’ 5" (6.8 m) 1’ 3" (0.38 m) 3’ 11" (1.2 m) -28 23’ 8" (7.2 m) 1’ 4" (0.41 m) 4’ 5" (1.4 m) -30 24’ 11" (7.6 m) 1’ 5" (0.43 m) IMPORTANT: Numbers in table based on 70’ (21.3 m) minimum bend radius, beacon housing, EZ- Connect, connector, transition sub, and 1/3 of first drill pipe (L, totaling 5’ [1.5 m]) in the ground before steering.

Prepare - 60 Prepare Jobsite JT5 Operator’s <strong>Manual</strong> Prepare Jobsite Jobsite hazards could cause death or serious injury. Use correct equipment and work methods. Use and maintain proper safety equipment. NOTICE: • If jobsite classification is in question or if the possibility of unmarked electric utilities exists, classify jobsite as electric. • Cutting high voltage cable can cause electrocution. Expose lines by hand before digging. • All vegetation near operator’s station must be removed. Contact with trees, shrubs, or weeds during electrical strike could result in electrocution. Mark Bore Path Mark your planned bore path and all located utility lines with flags or paint. Prepare Entry Point For bore to be successful, first pipe must be straight as it enters the ground. To help ensure that the first pipe does not bend, dig a small starting hole so that the first pipe is drilled into a vertical surface. To prevent bending or straining pipe, position drilling unit for straight entry. CMW
