Check for the following: • overall grade or slope • changes in elevation such as hills or open trenches • obstacles such as buildings, railroad crossings, or streams • signs of utilities (See “Inspect Jobsite” on page 73.) • traffic • access • soil type and condition • water supply • sources of locator interference (rebar, railroad tracks, etc.
JT30 /JT30 All Terrain Operator’s Manual Prepare - 72 Inspect Site Select Start and End Points Select one end to use as a starting point. Consider the following when selecting a starting point: Slope Fluid system should be parked on a level site. Consider how slope will affect drilling unit setup, bending pipe, and fluid flow out of hole. Traffic Vehicle and pedestrian traffic must be a safe distance from drilling equipment. Allow at least 10’ (3 m) buffer zone around equipment.
Prepare - 73 JT30 /JT30 All Terrain Operator’s Manual Classify Jobsite Classify Jobsite Inspect Jobsite • Follow U.S. Department of Labor regulations on excavating and trenching (Part 1926, Subpart P) and other similar regulations. • Contact your local One-Call (811 in USA) or the One-Call referral number (888-258-0808 in USA and Canada) to have underground utilities located before digging. Also contact any utilities that do not participate in the One-Call service.
JT30 /JT30 All Terrain Operator’s Manual Prepare - 74 Classify Jobsite Apply Precautions Once classified, precautions appropriate for jobsite must be taken. Electric Jobsite Precautions Use one or both of these methods. • Expose line by careful hand digging or soft excavation. Use beacon to track bore path. • Have service shut down while work is in progress. Have electric company test lines before returning them to service.
Prepare - 75 JT30 /JT30 All Terrain Operator’s Manual Plan Bore Path Plan Bore Path Plan the bore path, from entry to end, before drilling begins. The Ditch Witch Trac Management System Plus is available for planning your bore path. This special software can be run in the field using a laptop computer equipped with Windows® 95 or higher operating system. See your Ditch Witch dealer for details.
JT30 /JT30 All Terrain Operator’s Manual Prepare - 76 Plan Bore Path Recommended Bend Limits Ditch Witch drill pipes are designed to bend slightly during operation. Slight bending allows for steering and correcting direction. Bending beyond recommended limits will cause damage that might not be visible. This damage adds up and will later lead to sudden drill pipe failure. IMPORTANT: Consider recommended bend limits during any bend, not just during bore entry.
Prepare - 77 JT30 /JT30 All Terrain Operator’s Manual Plan Bore Path Bend Radius JT JT30 drill pipes have a tested minimum bend radius of 155’ (44.2 m). This means that a 90-degree bend in the bore path: • has a radius (A) of 155’ (44.2 m) • requires approximately 243’ (74 m) of drill pipe (B). AT JT30 All Terrain drill pipes have a tested minimum bend radius of 145’ (47.2 m). This means that a 90degree bend in the bore path: • has a radius (A) of 145’ (47.2 m) • requires approximately 228’ (69.

Prepare - 81 JT30 /JT30 All Terrain Operator’s Manual 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).
JT30 /JT30 All Terrain Operator’s Manual Prepare - 82 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.

JT30 /JT30 All Terrain Operator’s Manual Conduct a Bore - 122 Backream Backream Sometimes it is necessary to drill a pilot hole first, then enlarge the 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.
