Emergency Procedures

Emergency Procedures

Safety - 17


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



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.

CMW

Safety - 18



If an Electric Line is Damaged

If you suspect an electric line has been damaged and you are on drilling unit or bonded equipment, DO

NOT MOVE. Remain on drilling machine or mats and take the following actions. The order and degree of action will depend on the situation.

• Warn people nearby that an electric strike has occurred.

• Have someone contact electric company.

• Reverse drilling direction and try to break contact. Do not touch drill pipe with hands or hand-held tools.

• Press electric strike system status button.

• If alarm sounds again, stay where you are and wait for electric company to shut off power.

• If alarm does not sound and there is no other indication of a strike, wait at least one full minute before moving away from equipment. Utility might use automatic reclosers which will restart current flow. If alarm sounds again while waiting, stay where you are until electric company shuts off power.

• If alarm does not sound but all lights in strike indicator are on, assume strike is continuing and stay where you are until electric company shuts off power.

• Do not resume drilling or allow anyone into area until given permission by electric company.

If you suspect an electric line has been damaged and you are off drilling unit or bonded equipment, DO

NOT TOUCH ANY EQUIPMENT connected to drilling unit. Take the following actions. The order and degree of action will depend on the situation.

• Stay where you are unless you are wearing electric insulating boots. If you leave, do not return to area or allow anyone into area until given permission by electric company.

CMW



If a Gas Line is Damaged

Safety - 19




If you suspect a gas line has been damaged, take the following actions. The order and degree of action will depend on the situation.

• Immediately shut off engine(s), if this can be done safely and quickly.

• Remove any ignition source(s), if this can be done safely and quickly.

• Warn others that a gas line has been cut and that they should leave the area.

• Leave jobsite as quickly as possible.

• Immediately call your local emergency phone number and utility company.

• If jobsite is along street, stop traffic from driving near jobsite.

Gather Information

Gather Information

Prepare - 51

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


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.

CMW

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 54.)

• 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 54.


NOTICE:

• 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.

CMW

Manual

Inspect Site

Select Start and End Points

Prepare - 53

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.

Space

Check that starting and ending points allow enough space for gradual pipe bending. See “Minimum

Setback” on page 60.

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.

Apply Precautions

Once classified, precautions appropriate for jobsite must be taken.

Electric Jobsite Precautions

Prepare - 55



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




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.

CMW

Prepare - 56

Crystalline Silica (Quartz) Dust Precautions


Manual


NOTICE: Cutting, drilling, or working materials such as concrete, sand, or rock containing quartz may result in exposure to silica dust. Use water spray or other means to control dust. If workers are exposed to dust they 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.

CMW

Manual

Plan Bore Path

Plan Bore Path

Prepare - 57

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.

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 61 and use these measurements to

help plan your bore.

CMW

Prepare - 58

Manual


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.

Pipe Pitch

Ditch Witch drill pipe is tested to bend at a maximum percent pitch. For JT922 drill pipe, make sure pitch (A) changes no more than 6% 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 page 38.

Bend Radius

JT922 drill pipes have a tested minimum bend radius of 105’ (32 m). This means that a 90-degree bend in the bore path:

• has a radius (A) of 105’ (32 m)

• requires approximately 165’ (50 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.

IMPORTANT: Use the charts on the next page to keep bends within safe limits.

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 bore path 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.

CMW

Manual


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.

Prepare - 61

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.

Manual

Prepare Jobsite


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.

Steer Unit

To steer drilling unit, follow instructions for type of steering desired. See page 22 for more information.

To steer while moving forward, move one control slightly more than the other to turn in the desired direction. Drilling unit will gradually turn to left or right.

To steer while moving backward, move one control slightly more than the other to turn in the desired direction. Drilling unit will gradually turn to left or right.

For tight steering at low speed, one control to reverse and one control to forward to turn in the desired direction. Tracks will counter-rotate and turn drilling unit in a tight circle.

Tips to Reduce Track Wear

Rubber tracks are best suited at soil-based job sites with minimal rock and debris. Sharp objects such as gravel, steel shards, and broken concrete will damage rubber tracks and undercarriage components.

Excessive operation on concrete or asphalt will shorten track life. When storing your machine, keep tracks away from rain and direct sunlight.

Wash tracks daily to remove foreign objects and abrasive soil from sprockets and idler rollers. Drive slowly and make wide turns when possible. Regularly check undercarriage components (sprocket, rollers, idler)

for wear and damage. Maintain proper track tension. (See “Check Track Tension and Condition” on page 147.)

To prevent premature wear, avoid the following:

• Spinning tracks under heavy load.

• Turning on sharp objects such as stones, stumps and debris.

• Quick turns or “spin” turns on asphalt or concrete.

• Driving over curbs, ledges, and sharp objects.

• Driving with sidewall edges pressed against hard walls, curbs or other objects.

• Driving on slopes.

• Operating on corrosive materials such as salt or fertilizer. Wash immediately.

Correct Direction

Correct Direction

Correcting direction is a skill operators gain with experience and knowledge of equipment and soil conditions. These instructions cover only basic procedures. For information about specific equipment or jobsites, contact your Ditch Witch dealer.

To track progress and make corrections, one crew member locates the drill head and sends instructions to the operator. Corrections are made by tracking the drill head, comparing current position to bore plan, and steering drill head as needed.

Basic Rules

• Steering ability depends on soil condition; bit, drill head, and nozzle used; roll of drill head; and distance pushed without outer rotation.

•

All corrections should be made as gradually as possible. See “Recommended Bend Limits” on page 58.

• Over correcting will cause “snaking.” This can damage pipe and will make drilling and pullback more difficult. Begin to straighten out of each correction as early as possible.

• Do not push an entire piece of drill pipe into ground without rotation. This can exceed bend radius and cause pipe failure.

Procedure

1.

Locate drill head. Take readings available with your beacon and locating equipment such as:

• depth

• pitch

• left/right information

• temperature

• beacon roll

2.

Compare position to bore plan. Determine direction drilling should go.

3.

Position drill head.

4.

Push in drill pipe as needed to change direction.

5.

Rotate in remaining length of drill pipe.

CMW


Record Bore Path

Drill Head Position

The drill head position is determined by reading beacon roll. Roll is displayed as a clock face position.

1.

Read beacon roll.

2.

Slowly rotate pipe until locator displays desired beacon roll.

To change direction:

1.

Rotate pipe to clock position you intend to travel.

2.

Push pipe into ground.

To move forward without changing direction:

Rotate pipe into ground.


Record Bore Path

Locate drill head every half-length of pipe. As the job is completed, record the actual data for each drill pipe. List pitch and depth of each joint and a brief description of the procedure. In addition, draw a simple sketch of the site and record depth and rough location of pullback.

The Trac Management System Plus is also available for plotting and tracking your bore path. It utilizes the

750 Tracker, 750 Display, a tracking beacon, and special software. The display can store jobs in its memory or the system can be run in the field using a laptop computer equipped with the Windows

®

95 or higher operating system. See your Ditch Witch dealer for details.

Surface Drill Head


Surface Drill Head



NOTICE:

• Tracker operator and drill operator should maintain two-way communication.

• Keep everyone clear of the exposed drill string.

• No one should enter pit until clear communication is given by the drill operator that the drill unit is shut down. If using tracker control, do not enter pit until tracker control is turned off and green light on drill unit is lit.

• Drill operator should be instructed to discontinue drill string rotation as soon as drill bit exits the bore. Use thrust only to extend drill string beyond exit hole.

1.

Guide drill head to target pit or up through surface. Make all bends gradual. See “Recommended

Bend Limits” on page 58.

2.

Clean area around exit point.

3.

If using tracker control mode, tracker operator turns off tracker to disable drilling unit thrust/pullback and rotation hydraulics. Tracker operator waits for green light to enter pit and change tools.

If not using tracker control mode, tracker operator signals to drilling unit operator to stop engine before changing downhole tools.

4.

Turn fluid flow control to off position as soon as drill head emerges.

5.

Clean drill head especially around threads.

6.

Disconnect EZ-Connect joint or use quick wrench to remove drill head. Keep threads clean. See

“Quick Wrench” on page 114.

Assemble Backream String

Assemble Backream String


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.



NOTICE: Continue to use strike system during backreaming.


NOTICE:

• Maintain two-way communication with tracker operator.

• Begin backream only when tracker operator has communicated that everyone is clear of the exposed backream string or has disabled thrust and rotation hydraulics using tracker control.

• Do not allow anyone to stand to the side of the exposed drill string. Drill string and backreamer can move sideways suddenly if rotated while away from the exit hole.

CMW




To test for current at strike levels:

1.

Put two or three loops through current transformer.

2.

Follow steps above to test.

3.

Display should show the following:

• All lights should turn on.

• Alarm and strobe should turn on.

With two loops,

• Current "A" should be 80-110%.

• Strike indication might go on and off.

With three loops,

• Current should be 130-160%.

• Strike indication should be continuous.

Voltage Test

1.

Place voltage limiter on something insulated from ground and drilling unit (such as dry board or tire), but near frame of drilling unit.

2.

Clip one lead to frame.

3.

Clip other lead to one voltage limiter mount.

4.

Move simulator switch to "voltage" and press test button.

5.

Watch screen and lights above display on strike system.

• All lights should turn on.

• Alarm and strobe should turn on.

• Voltage "V" should show 90-110%.

It is normal for simulator voltage levels to drift below strike level. When this happens, light in triangle should go off and alarm and strobe should stop working. If the level drifts above strike level again, light, alarm, and strobe should be turned on again.

• Quik-Gel™ dry powder bentonite (p/n 259-804)

• E-Z Mud™ liquid polymer (p/n 259-805)

• Liqui-Trol™ liquid polymer suspension (p/n 259-808)

• Quik-Trol™ dry powder polymer (p/n 259-809)

• Bore-Gel™ drilling fluid (p/n 259-807)

• Con-Det™ water-soluble cleaning solution (p/n 259-810)

Guidelines

Match drilling fluid to soil type. This chart is meant as a guideline only. See your local Ditch Witch dealer for soil conditions and drilling fluid recommendations for your area. Also see our interactive Drilling Fluid

Formulator at www.ditchwitch.com.

Soil type smooth, flowing sand coarse sand or light soil heavy clay swelling clay rock

Drilling fluid recommendation bentonite or Bore-Gel + medium chain polymer bentonite or Bore-Gel long chain polymer + Con-Det long chain polymer + Con-Det

Bore-Gel

Polymer

This drilling fluid additive provides excellent lubrication and increases viscosity in average soils and heavy clay. In swelling clay, polymer can reduce swelling that traps pipe in the bore.

There are two types of polymer:

• long chain such as Baroid EZ-Mud

• medium chain such as Baroid Quik-Trol

CMW




Bentonite

Bentonite is a dry powder. When properly mixed with water, it forms a thin cake on bore walls, lubricating the bore, keeping it open, and holding fluid in the bore.

Some things to remember when mixing bentonite:

• Use clean water free of salt, calcium, or excessive chlorine.

• Use water with pH level between 9 and 10.

• Use water with hardness of less than 120 ppm.

• Do not use bentonite containing sand.

• Mix bentonite thoroughly or it will settle in tank.

• Do not mix bentonite to a funnel viscosity of over 50.

For information on measuring funnel viscosity, see “Funnel Viscosity” on page 105.

Mixtures

Bentonite does not mix well in water containing polymer. To use both, mix bentonite first, then add polymer.

When adding other products follow the order listed below.

NOTICE:

• If chemicals are added in the wrong order, they will not mix properly and will form clumps.

• If tank contains bentonite/polymer mix and more drilling fluid is needed, completely empty tank and start with fresh water before mixing another batch.

General mixing order:

1.

Soda ash

2.

Bentonite

3.

Polymer

4.

Con-Det

Bore-Gel contains premixed bentonite, polymer, and soda ash. Use approximately 15 lb/100 gal (7 kg/380

L) in normal drilling conditions, up to 45 lb/100 gal (21 kg/380 L) in sand or gravel and up to 50 lb/100 gal

(23 kg/380 L) in rock.

Drilling Fluid Requirements

1.

Determine drilling conditions and choose appropriate drilling fluid mix.

2.

Estimate amount of supplies needed and check availability.

• Drilling fluid

• Water supply. If more water than can be carried with the unit will be needed, arrange to transport additional water.

• Bentonite and/or polymer

3.

Check water quality.

• Use meter or pH test strips to test pH of water. If pH is below 9.0, add 1 lb (454 g) soda ash per tank. Test and repeat until pH is between 9 and 10.

• Check water hardness using hardness test strips. Treat with soda ash if hardness exceeds 125 ppm.

CMW



Funnel Viscosity


Viscosity is the measure of internal resistance of a fluid to flow; the greater the resistance, the higher the viscosity. Viscosity of drilling fluids must be controlled.

To determine viscosity, you will need a Marsh funnel (p/n 259-267) and a measuring cup, available from your Ditch Witch dealer.

IMPORTANT: Make sure Marsh funnel is clean and free of obstruction and that you have a stopwatch available for timing the viscosity.

1.

Using wash hose and a clean container, take a fresh sample of drilling fluid. The sample must be at least 1.5 qt (1.4 L).

2.

With finger over bottom of funnel, fill with fluid from the container through the screen until fluid reaches the bottom of the screen.

3.

Move funnel over 1 qt (.95 L) container.

4.

Remove finger from bottom of funnel and use the stopwatch to count the number of seconds it takes for 1 qt (.95 L) of fluid to pass through the funnel. The number of seconds is the viscosity.

5.

Thoroughly rinse measuring cup and Marsh funnel.

CMW


Tracker Control

Overview


Tracker Control



This mode allows the tracker operator to disable hydraulic power to drilling unit thrust and rotation.

NOTICE: This mode does not disable thrust and rotation immediately. Functions are disabled within 16 seconds.

Use tracker control any time you change downhole tools or during other times when the drill string is exposed. Tracker control works by stopping communication between the tracker and the display. When this happens, the green tracker control light on the drilling unit comes on and thrust and rotation are disabled.

Operation

Enable Thrust and Rotation

1.

Start drilling unit.

2.

Turn off 750 Display.

3.

Press and hold DOWNLOAD (1) while turning on 750 Display until a four-digit code (2) appears.

CMW




4.

Turn on 750 Tracker and check four-digit code.

If codes on tracker and display match, thrust and rotation hydraulics on the drilling unit are enabled.

If codes on tracker and display do not match, adjust tracker code:

• Press and hold fore/aft/left/right button while making the following adjustments.

• Use ON/OFF to advance first two digits

(1). Use DEPTH to lower first two digits.

• Use up arrow to advance last two digits

(2). Use down arrow to lower last two digits.

• Press and hold each button to advance or lower value quickly.

• To start sending code from the tracker to the display, press and hold fore/aft/left/right button and press MODE. Thrust and rotation hydraulics on the drilling unit are now enabled.

Troubleshooting Tip: If thrust and rotation are not enabled:

• Check whether the green tracker control light located on drilling unit anchoring console is on. If it is, communication has probably stopped between tracker and display, or tracker is set to incorrect code.

• If communication cannot be restored, install tracker control key (shown) in drilling unit. Green tracker control light located on anchoring console will go off. Thrust and rotation will function.

5.

Remove tracker control key (shown) from set-up console at rear of drilling unit. Keep in tracker operator’s possession.

6.

Drill and track bore.

CMW


Disable Thrust and Rotation

1.

When drill head enters target pit or exits the ground, turn off tracker.

After 8-16 seconds, green tracker control light

(shown), located on drilling unit anchoring console, will come on. Hydraulic power to thrust and rotation will be disabled.

2.

Turn engine off.



IMPORTANT: Tracker operator cannot disable thrust and rotation from tracker if tracker control key (shown) is installed in drilling unit and turned to the disable

position. See “Tracker control key” on page 23 for more information.

NOTICE: If you are not using tracker control, turn off drilling unit before changing downhole tools.

3.

Change downhole tools.

4.

If you are tracking backreamer’s path, turn on tracker and enable code transmission. After 8-16 seconds, green tracker control light on drilling unit anchoring console will go off and thrust and rotation will function.

Backream Fluid Requirements

Backreaming is only successful when enough fluid reaches the bore. The amount of fluid needed depends on size of bore and soil condition.

Follow these steps to find the minimum amount of fluid needed in perfect conditions.

IMPORTANT: Use more fluid than recommended or the backream might be dry and unsuccessful.

Instructions

1.

Find amount of fluid needed for your size of backreamer. See the table on the next page.

2.

Multiply this number by distance per minute you plan to backream. The answer is an estimate of amount of fluid you will need for each minute of backreaming.

Example

U.S. A 6” backreamer requires at least 1.47

gal/ft.

Metric A 152-mm backreamer requires at least

18.24 L/m.

U.S. 1.5 gal x 2 ft/min = 3 gal for each minute of backreaming.

Metric 18 L x .5 m/min = 9 L for each minute of backreaming

IMPORTANT: After you have determined how much fluid you will need, see your Ditch Witch dealer for nozzle recommendations.

Drill Pipe

Drill Pipe

Perform Regular Drill Pipe Care

Precondition New Pipe

Repeat this procedure three times for each piece of pipe before it is used the first time:

1.

Hand-lubricate entire surface of threads and shoulders of both ends of pipe with copper base tool

joint compound. See page 130 for correct lubricant.

2.

Join pipe and tighten joint.

3.

Break joint.

NOTICE: Failure to follow this procedure could result in fused joints. Pipe will be damaged or destroyed.

Lubricate Joints Before Each Use

Lubricate threads and shoulders of male joints with copper base tool joint compound. This prevents rust

and reduces wear on shoulders and threads. See page 130 for correct lubricant.

Clean the Threads

Clean the threads as needed with high-pressure water and detergent.

NOTICE: Do not use gasoline or other petroleum-based solvents. This prevents tool joint compound from sticking to the joints and will reduce thread life.

After cleaning, hand lubricate entire surface of threads and shoulders.

CMW


Drill Pipe

Use Caps and Plugs

Install plug on saver sub before transporting.

Cap and plug male and female ends of drill pipe during prolonged storage.


Replace Worn Saver Sub

Because each pipe comes in contact with the saver sub, check saver sub regularly for wear. Replace it

when it is worn, or it will damage your drill pipe. See page 147 for replacement procedure.

Precondition a new saver sub the same way you do new pipe. See “Precondition New Pipe” on page 116.

Rotate Pipe Order

Because the lead drill pipe is in the ground longer, it is subjected to higher shock loads and experiences more wear. To help spread this wear evenly over all pipe, move the lead pipe from the previous job out of the first position.

CMW


Use Drill Pipe Correctly

Align the Joints

Always carefully align the male and female ends of pipe before screwing them together.

Poor alignment can damage the threads and destroy the usefulness of the joint.

IMPORTANT: The first pipe drilled must be in a straight line with the unit. A misaligned pipe can damage threads on each pipe that is added.

Clamp Pipe Correctly

Clamp on pipe when joint is centered between wrenches. Clamp only on the tool joint of the drill pipe as shown. This portion of the drill pipe is designed for clamping and is considerably thicker and stronger than the rest of the pipe.

NOTICE: Clamping anywhere else on the pipe will weaken the pipe. Pipe can later break, even when operating under normal loads.

See “Clamp Pipe” on page 79 for more

information.


Drill Pipe

CMW


Drill Pipe

Make Up and Break Out Joints Correctly


• Make up and break out joints slowly. Do not ram pipes together during makeup or force them apart during breakout. Carefully time rotation with carriage travel speed, and always connect and disconnect joints slowly and deliberately. This will help prevent thread crossing, galling, and shoulder swelling.

• Torque joints fully. Once the joint is connected and the shoulder faces are touching, torque them to full machine torque. Improperly torqued joints will damage the shoulder faces and threads, and will cause joints to leak or break while drilling or backreaming.

Do not Overwork the Pipe

Never exceed the bend radius for your pipe. See “Recommended Bend Limits” on page 58. Do not

oversteer.

NOTICE: Bending pipe more sharply than recommended will damage pipe and cause failure.

Approved Fuel

This engine is designed to run on diesel fuel. Use only high quality fuel meeting ASTM D975 No. 2D,

EN590, or equivalent. At temperatures below 32° F (0° C) winter fuel blends are acceptable. See the engine operation manual for more information.

IMPORTANT: For machines operated in the U.S.: The engine in this product is certified to operate on low sulfur diesel fuel (LSD) with a sulfur content of 500 ppm (0.05%) or less. Use LSD or ultra low sulfur diesel fuel (ULSD) only. Using fuels with higher sulfur content will affect exhaust emissions. Such action is a violation of the US Clean Air Act and US EPA regulations and will result in fines.

For machines operated outside the U.S.: Fuel sulfur content should be less than 5000 ppm (0.5%).

Worldwide fuel sulfur regulations vary widely. Fuel used should always comply with local regulations. If fuel sulfur content exceeds 5000 ppm, use a lube oil meeting API CJ-4 (or other low SAPS equivalent) and fuel with sulfur content above 500 ppm (0.05%, low sulfur diesel in the U.S.), reduce oil change interval to 250 hours.

Biodiesel blends up to 5% (B5) are approved for use in this unit. The fuel used must meet the specifications for diesel fuel shown above. In certain markets, higher blends may be used if certain steps are taken. Extra attention is needed when using biodiesel, especially when operating in cold weather or storing fuel. Contact your Ditch Witch dealer or the engine manufacturer for more information.
