Emergency Procedures

Emergency Procedures
Jobsite hazards could cause death or serious injury. Use correct equipment and work methods. Use and maintain proper safety equipment.
Before operating any equipment, review emergency procedures and check that all safety precautions have been taken.
EMERGENCY SHUTDOWN - Turn ignition switch to stop position or push remote engine stop button (if equipped).

Electric Strike Description

Electric shock. Contacting electric lines will cause death or serious injury.
Know location of lines and stay away.
When working near electric cables, remember the following:
Electricity follows all paths to ground, not just path of least resistance.
Pipes, hoses, and cables will conduct electricity back to all equipment.
Low voltage current can injure or kill. Many work-related electrocutions result from contact with less than 440 volts.
Most electric strikes are not noticeable, but indications of a strike include:
power outage
smoke
explosion
popping noises
arcing electricity
If any of these occur, or if strike alarm sounds or flashes, assume an electric strike has occurred.

Gather Information

Gather Information
A successful job begins before the bore. The first step in planning is reviewing information already available about the job and jobsite.

Review Job Plan

Review blueprints or other plans and make sure you have taken bore enlargement during backreaming and pullback into account. Check for information about existing or planned structures, elevations, or proposed work that may be taking place at the same time.

Notify One-Call Services

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.

Examine Pullback Material

Ask for a sample of the material you will be pulling back. Check its weight and stiffness. Contact the manufacturer for bend radius information. Check that you have appropriate pullback devices.

Arrange for Traffic Control

If working near a road or other traffic area, contact local authorities about safety procedures and regulations.

Plan for Emergency Services

Have the telephone numbers for local emergency and medical facilities on hand. Check that you will have access to a telephone.
Prepare - 62 JT60/JT60 All Terrain Operator’s Manual

Inspect Site

Inspect Site
Inspect jobsite before transporting equipment. 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 64.)
traffic
access
soil type and condition
water supply
sources of locator interference (rebar, railroad tracks, etc.)
Take soil samples from several locations along bore path to determine best bit and backreamer combinations.

Identify Hazards

Identify safety hazards and classify jobsite. See “Classify Jobsite” on page 64.
Jobsite hazards could cause death or serious injury. Use correct equipment and work methods. Use and maintain proper safety equipment.
To help avoid injury:
Wear personal protective equipment including hard hat, safety eye wear, and hearing protection.
Do not wear jewelry or loose clothing.
Notify One-Call and companies which do not subscribe to One-Call.
Comply with all utility notification regulations before digging or drilling.
Verify location of previously marked underground hazards.
Mark jobsite clearly and keep spectators away.
Remember, jobsite is classified by hazards in place -- not by line being installed.
JT60/JT60 All Terrain Operator’s Manual Prepare - 63
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
Always level machine before drilling. 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.
Space
Check that starting and ending points allow enough space for gradual pipe bending. See “Minimum Setback” on page 72.
Check that there is enough space to work and to set up electric strike system.
Comfort
Consider shade, wind, fumes, and other site features. Drill downhill when possible so fluid will flow away from drilling unit.
Prepare - 64 JT60/JT60 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.
Inspect jobsite and perimeter for evidence of underground hazards, such as: – “buried utility” notices
– utility facilities without overhead lines – gas or water meters – junction boxes – drop boxes – light poles – manhole covers – sunken ground
Have an experienced locating equipment operator sweep area within 20’ (6 m) to each side of bore path. Verify previously marked line and cable locations.
Mark location of all buried utilities and obstructions.
Classify jobsite.

Select a Classification

Jobsites are classified according to underground hazards present.
If working . . . then classify jobsite as . . .
within 10’ (3 m) of a buried electric line electric within 10’ (3 m) of a natural gas line natural gas in sand, granite, or concrete which is capable of producing
crystalline silica (quartz) dust within 10’ (3 m) of any other hazard other
IMPORTANT: If you have any doubt about jobsite classification, or if jobsite might contain unmarked hazards, take steps outlined previously to identify hazards and classify jobsite before working.

JT60/JT60 All Terrain Operator’s Manual Prepare - 65
Classify Jobsite

Apply Precautions

Once classified, precautions appropriate for jobsite must be taken.
Electric Jobsite Precautions
Electric shock. Contacting electric lines will cause death or serious injury.
Know location of lines and stay away.
In addition to using a directional drilling system with an electric strike system, use one or both of these methods.
Expose line by careful hand digging or soft excavation. Use beacon to track bore path. Have someone observe clearance between drill head and backreamer when crossing a line.
Have service shut down while work is in progress. Have electric company test lines before returning them to service.
Natural Gas Jobsite Precautions
Fire or explosion possible. Fumes could ignite and cause burns. No
smoking, no flame, no spark.
Explosion possible. Serious injury or equipment damage could occur.
Follow directions carefully.
In addition to using a directional drilling system and positioning equipment upwind from gas lines, use one or both of these methods.
Expose lines by careful hand digging or soft excavation. Use beacon to track bore path. Have someone observe clearance between drill head and backreamer when crossing a line.
Have gas shut off while work is in progress. Have gas company test lines before returning them to service.

Classify Jobsite
Crystalline Silica (Quartz) Dust Precautions
Jobsite hazards could cause death or serious injury. Use correct
equipment and work methods. Use and maintain proper safety equipment.
To help avoid injury:
Use water spray or other means to control dust when cutting, drilling, or working materials such as concrete, sand, or rock containing quartz. The dust may contain silica.
Workers exposed to dust must wear appropriate breathing protection. Silica dust may cause lung disease and is known to the State of California to cause cancer.
Follow OSHA or other guidelines for exposure to crystalline silica when trenching, sawing or drilling through material that might produce dust containing crystalline silica (quartz).
Other Jobsite Precautions
You may need to use different methods to safely avoid other underground hazards. Talk with those knowledgeable about hazards present at each site to determine which precautions should be taken or if job should be attempted.

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. See your Ditch Witch dealer for details.
If not using Trac Management System Plus, mark the bore path on the ground with spray paint or flags, or record it on paper for operator reference.
For complicated bores, consult an engineer. Have the jobsite surveyed and bore path calculated. Be sure the engineer knows minimum entry pitch, bend limits of drill pipe, bend and tension limits of pullback material, pipe lengths, and location of all underground utilities.
For less complicated bores, plan the bore based on four measurements:
recommended bend limit
entry pitch
minimum setback
minimum depth
IMPORTANT: See the following pages for more information about these measurements. If not using Trac Management System Plus, see “Bore Path Calculator” on page 73 and use these measurements to help plan your bore.

Recommended Bend Limits

NOTICE: Only use approved JT60 Power Pipe HD, All Terrain Power Pipe, or Power Pipe Forged with this drilling unit.
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.
Pipe Pitch
Ditch Witch drill pipe is tested to bend at a maximum percent pitch. For JT60 or JT60 All Terrain drill pipe, make sure pitch (A) changes no
more than 7% over the full length of each pipe.
NOTICE: Bending drill pipe more sharply than recommended will damage pipe and cause failure over time. Changes in pitch must be equally distributed over the length of a pipe. Maximum changes in pitch within 1-2’ (300-600 mm) of pipe create sharp bends that will damage pipe.
Monitor the pitch of each pipe with the remote display on the operator’s console. (See tracking system operation instructions.)
Bend Radius
JT60 All Terrain drill pipes have a tested minimum
bend radius of 205’ (63 m). This means that a 90­degree bend in the bore path:
has a radius (A) of 205’ (63 m)
requires approximately 471’ (143.6 m) of drill pipe (B).
NOTICE: Bending drill pipe more sharply than recommended will damage the pipe and cause failure over time.
If bend radius is reduced, drill pipe life is reduced.
If bend radius is increased, drill pipe life is increased.
JT60/JT60 All Terrain Operator’s Manual Prepare - 69
Plan Bore Path
JT60 Power Pipe drill pipes have a tested minimum bend radius of 170’ (57.8 m). This means that a 90­degree bend in the bore path:
has a radius (A) of 170’ (57.8 m)
requires approximately 267’ (81.4 m) of drill pipe (B). JT60 Power Pipe Forged drill pipes have a tested
minimum bend radius of 168.7’ (51.4 m). This means that a 90-degree bend in the bore path:
has a radius (A) of 168.7’ (51.4 m)
requires approximately 265’ (80.8 m) of drill pipe (B).
NOTICE: Bending drill pipe more sharply than recommended will damage the pipe and cause failure over time.
If bend radius is reduced, drill pipe life is reduced.
If bend radius is increased, drill pipe life is increased.

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).
Measure from the ground to back end of frame (H2).
Subtract (H1) from (H2). Record this number.
Measure the distance between front and back points (C).
Divide (H2-H1) by (C), then multiply by 100. This is your pitch.
IMPORTANT: A shallow entry pitch (A1) allows you to reach horizontal sooner and with less bending. Increasing entry pitch (A2) makes minimum setback longer and deeper.

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.
JT60/JT60 All Terrain Operator’s Manual Prepare - 73
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.

Prepare Jobsite

Prepare Jobsite
Jobsite hazards could cause death or serious injury. Use correct equipment and work methods. Use and maintain proper safety equipment.
To help prevent injury:
Classify jobsite as electric if jobsite classification is in question or if the possibility of unmarked electric utilities exists.
Cutting high voltage cable can cause electrocution. Expose lines by hand before digging.

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.

Steer Unit

Safe Slope Operation

Tipover possible. Machine can tip over and crush you.
To help avoid injury:
Always operate with heavy end uphill.
Drive cautiously at all times.
Never jerk control levers. Use a steady even motion.
Do not park unit on slope without lowering anchor frame to the ground, returning all controls to neutral position, shutting down unit, and applying parking brake.
Operating safely on a slope depends upon many factors including:
Distribution of machine weight, including front loading and absence of load
Height of load
Even or rough ground conditions
Potential for ground giving way causing unplanned tilt forward, reverse or sideways
Nearness of ditches, ruts, stumps or other obstructions and sudden changes in slope
Speed
Turning
Braking performance
Operator skill
These varying factors make it impractical to specify a maximum safe operating angle in this manual. It is therefore important for the operator to be aware of these conditions and adjust operation accordingly. Maximum engine angle and braking performance are two absolute limits which must never be exceeded. These maximums are stated below since they are design limits. These design limits usually exceed the operating limits and must never be used alone to establish safe operating angle for variable conditions.
Maximum engine lubrication angle – 43° Maximum service brake retarding force – equal to traction of both tracks. Maximum secondary brake retarding force – equal to traction of one track. Maximum park brake holding force – equal to traction of both tracks.

Position Equipment

Position Equipment
1. Review bore plan and select drilling unit position and fluid unit position.
2. Move equipment into selected positions.

Connect Fluid System

Electric shock. Contacting electric lines will cause death or serious injury.
Know location of lines and stay away.
To help avoid injury, do not connect drilling unit to a public or private (business or home) water supply. If an electrical strike occurs while drilling unit is connected to a fluid system, the fluid system will also become electrified.
1. Connect fluid hose from mixing system to drilling fluid pump. A 3” (76 mm) or larger, non-collapsible hose is required.
2. Install y-strainer between mixing unit and drilling fluid pump. Position strainer so that drilling fluid flows in the direction of the arrow. In most cases, positioning strainer at outlet of mixing unit gives best results.
IMPORTANT: Clean y-strainer regularly.

Start System

1. Start drilling unit and remote fluid unit. Allow both engines to warm up.
IMPORTANT: Ensure that mixture of drilling fluid matches drilling conditions.
2. Enable tracker control mode if desired. See “Tracker Control” on page 133.
3. Press top of drilling unit throttle switch until engine is at full throttle.
4. Press and hold quick fill fluid pump switch until pipe fills and fluid pressure begins to rise.

Prime Drilling Fluid Pump

Prime Drilling Fluid Pump
Incorrect procedures could result in death, injury, or property damage.
Learn to use equipment correctly.
To help avoid injury, prime the drilling fluid pump before use. Failure to prime the drilling fluid pump will cause flow fluctuations, which will make it difficult to control the wash wand.
Pressurized fluid or air could pierce skin and cause injury
or death. Stay away.
Prime drilling fluid pump each time the tank is changed. To prime the pump:
1. Fill drilling fluid hose and connect hose to unit.
2. Operate mixing/transfer pump at full speed for 1 - 3 minutes to discharge air from system.
3. Return mixing/transfer pump to normal operating speed and continue the bore.
4. If drilling fluid pressure surges are observed, repeat step 2.

Operate Carriage Control

Operate Carriage Control
The thrust/rotation control has eight zones that allow four basic functions (forward, backward, clockwise, counterclockwise) to be combined. The chart below summarizes functions that occur when control is put at a combined position. Operator must be in seat for control to function.

Clamp Pipe

Clamp Pipe
Turning shaft can kill you or crush arm or leg. Stay away.
To help avoid injury, clamp pipe only where shown. Clamping anywhere else on the pipe will weaken the pipe. Pipe can later break, even when operating under normal loads.
Clamp on pipe when joint is centered between wrenches (1 and 2). Always clamp on the larger diameter areas on either side of the tool joint face.
