JT100/JT100 All Terrain Operator’s Manual Prepare - 89 Plan Bore Path Entry Pitch Entry pitch is the slope of the drill frame compared with the slope of the ground. Determine entry pitch one of two ways: 1. With Pitch Beacon • Lay pitch beacon on the ground and read pitch. • Lay pitch beacon on drill frame and read pitch. • Subtract ground pitch from drilling unit pitch. 2. With Measurements • Measure from the ground to front end of drill frame (H1).
PAGE 91
Prepare - 90 JT100/JT100 All Terrain Operator’s Manual Plan Bore Path Minimum Setback Setback is the distance from the entry point to where pipe becomes horizontal (B1). NOTICE: If setback is too small (B2), you will exceed bend limits and damage the pipe. 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.

Conduct a Bore - 128 JT100/JT100 All Terrain Operator’s Manual Backream Backream Sometimes it is necessary to enlarge the pilot hole to accommodate larger product. As a general rule, the final hole should be 1.5 times larger than the diameter of the product being installed. The number of passes needed depends on soil conditions. Do not try to increase hole size too much in one pass. Several passes using successively larger reamers will save wear on machine. Moving tools will kill or injure.
