Guidelines

Guidelines
Follow these guidelines before operating any jobsite equipment:

• Complete proper training and read operator’s manual before using equipment.
• 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. Mark proposed path with white paint prior to contacting One-Call or
utilities.
• Classify jobsite based on its hazards and use correct tools and machinery, safety equipment, and work
methods for jobsite.
• Mark jobsite clearly and keep spectators away.
• Wear personal protective equipment.
• Review jobsite hazards, safety and emergency procedures, and individual responsibilities with all
personnel before work begins. Safety videos are available from your Ditch Witch® dealer.
• Replace missing or damaged safety shields and safety signs.
• Use equipment carefully. Stop operation and investigate anything that does not look or feel right.
• Do not operate unit where flammable gas may be present.
• Contact your Ditch Witch dealer if you have any question about operation, maintenance, or equipment

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, assume an electric strike has occurred.

CMW®
Safety - 14 RT100 Powershift Operator’s Manual
Emergency Procedures

If an Electric Line is Damaged

If you suspect an electric line has been damaged and you are on tractor, DO NOT MOVE. Remain on
tractor and take the following actions. The order and degree of action will depend upon the situation.

• Warn people nearby that an electric strike has occurred. Instruct them to leave the area and contact
utility.
• Raise attachments and drive from immediate area.
• Contact utility company to shut off power.
• Do not return to jobsite or allow anyone into area until given permission by utility company.

If you suspect an electric line has been damaged and you are off tractor, DO NOT TOUCH TRACTOR.
Take the following actions. The order and degree of action will depend upon the situation.

• LEAVE AREA. The ground surface may be electrified, so take small steps with feet close together to
reduce the hazard of being shocked from one foot to the other. For more information, contact your
Ditch Witch dealer.
• Contact utility company to shut off power.
• Do not return to jobsite or allow anyone into area until given permission by utility company.

Gather Information

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

Review Job Plan

Review blueprints or other plans. 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.

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
RT100 Powershift Operator’s Manual Prepare - 63
Inspect Site

Inspect Site

• changes in elevation such as hills or other 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

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.

CMW
Prepare - 64 RT100 Powershift 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 trench
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
crystalline silica (quartz) dust

within 10’ (3 m) of any other hazard other

NOTICE: 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.

CMW
RT100 Powershift Operator’s Manual Prepare - 65
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.

• 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 positioning equipment upwind from gas lines, use one or both of these methods.

• Expose lines by careful hand digging or soft excavation.

• Have gas shut off while work is in progress. Have gas company test lines before returning them to
service.

Crystalline Silica (Quartz) Dust Precautions

Breathing crystalline silica dust may cause lung disease. Cutting, drilling,
or working materials such as concrete, sand, or rock containing quartz may result in
exposure to silica dust. Use dust control methods or appropriate breathing protection
when exposed to silica dust.

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.

Safe Slope Operation

Tipover possible. Machine can tip over and crush you.

To help avoid injury:

• Only operate equipment on slopes if absolutely necessary.

• Always operate with heavy end uphill. Keep attachments low and travel up and down the slope.
• Drive cautiously, in the lowest gear, at all times.
• Never jerk control levers. Use a steady even motion.
• Do not park unit on slope without lowering digging attachment to the ground, returning all controls
to neutral position, shutting down unit, and applying parking brake.
• Assess the site to determine if the slope and conditions are conducive to a safe working
environment.

Operating safely on a slope depends upon many factors including:

• Distribution of machine weight, including front loading and absence of load

• Height of load
• Saturated, 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.

RT100 Powershift Operator’s Manual Drill - 93
Prepare Jobsite and Equipment

Prepare Jobsite and Equipment

Approach Trench (1)
1. Mark path where you intend to bore.
2. Dig an approach trench (1) along the intended
drill path.

IMPORTANT: The approach trench should

be at least:

• deep enough for pipe to lay flat and

enter soil at correct angle
• 20’ (6 m) long
• 4” (100 mm) wide

Target Trench (2)

1. Select a completion point for the drilling project.
2. Dig a target trench (2) across the anticipated completion point.

IMPORTANT: The actual length of the target trench depends on soil conditions and length of pipe
sections. Make it deep enough for drill bit to enter slightly above the trench floor.

Drill Pipe and Equipment

1. Assemble at least 20’ (6 m), but not more than
30’ (9 m), of drill rod.

NOTICE: More than 10-15’ (3-4.5 m) of drill

rod out of the trench increases the
tendency of drill rod to bend.

2. Install drill bit to the cutting end of the drill string.

3. Put drill string in approach trench.
4. Move tractor to the approach trench and align the drilling attachment with the intended bore path.
5. Turn off engine.
6. Attach drill string to drilling attachment.

EMERGENCY SHUTDOWN: Release drilling control and turn ignition switch to STOP.

1. Start tractor’s engine and begin clockwise (forward) rotation.

2. Slowly advance tractor while maintaining clockwise rotation.

NOTICE:

• Drilling too quickly causes bit to drift off course and may bend drill rod. After bore path is
established, speed may be slightly increased.
• If drill rod starts to bend, stop forward movement of unit and back the unit slightly until rod
straightens. Do not drill with bent rod.
• If drill rod hits an obstruction, rotate drill string counterclockwise to back up slightly.

Using Drill String Guide

Turning shaft will kill you or crush arm or leg. Stay away.

To help avoid injury: Keep everybody at least 10’ (3 m) away from drill rod during
operation. Do not straddle trench or drill rod while drilling.

Use drill string guide to align drill string as it

enters the soil. When using drill string guide,
follow these guidelines:

• Use only approved Ditch Witch drill string

guide
(p/n 179-737).
• Stand only on the left side of the approach
trench.
• Keep drill string guide at least 3’ (1 m) behind
bit.
• Use drill string guide to control only the first 5’
(1.5 m) of the bore path.
• After drilling 5’ (1.5 m), stop unit and remove
drill string guide.
• Do not use drill string guide during
backreaming or any time the drill string is
being pulled back.

CMW
RT100 Powershift Operator’s Manual Drill - 95
Add Rod

Add Rod
1. Stop drilling attachment.
2. Back up tractor 6" (150 mm) to loosen drill rod in ground.
3. Disconnect drill rod from drilling attachment.
4. Move tractor away from bore.
5. Add one drill rod to continue bore.

Backream
After drill bit enters target trench, the bore hole may be enlarged by changing the drill bit to a backreamer
and drawing it back through the initial bore.

1. Turn tractor ignition switch to STOP.

2. Replace drill bit with backreamer.
3. Start tractor engine and begin clockwise rotation.

IMPORTANT: Always rotate clockwise during backreaming. Rotate counterclockwise only to

dislodge a dry bore bit or reamer that has seized in the bore hole.

4. Slowly back up tractor while maintaining rotation.

5. When backreamer exits the bore hole, stop rotation immediately.

IMPORTANT:

• Do not try to increase hole size too much in one pass. Several passes using successively
larger reamers will save wear on machine.
• During backreaming, keep drill string straight. Sharp bends in the drill rod at the motor
coupling can cause rod failure.

Chain, Teeth, and Sprockets

Chain, Teeth, and Sprockets

Chain and Tooth Maintenance
• Always replace sprockets at the same time you replace the digging chain. Sprockets and chain are
designed to work together. Replacing one without the other will cause premature wear of the new part.
• Keep digging teeth sharp. Using dull, worn teeth will decrease production and increase shock load to
other trencher components. It can also cause chain stretch, which leads to premature chain wear and
failure.
• Maintain the proper amount of tension on the digging chain. Overtightening will cause chain stretch
and loss of machine performance. For correct tightening procedure, see page 117.
• Use the tooth pattern most appropriate for your digging conditions. If you move to a different soil type,
contact your Ditch Witch dealer for information about the most effective chain type and tooth pattern.

• Use caution and wear personal protective equipment such as safety eyewear, when charging or
cleaning battery.
• Keep sparks, flames, and any ignition source away from batteries at all times. Internal contents are
extremely hazardous. Leaking fluid is corrosive. Battery may be explosive at higher temperatures.
• NEVER lean over battery when making connections.
• Do not allow vehicles to touch when charging.
• Do not attempt to charge a battery that is leaking, bulging, heavily corroded, frozen, or otherwise
damaged.
• NEVER short-circuit battery terminals for any reason or strike battery posts or cable terminals.
• Refer to MSDS for additional information regarding this battery.

Before You Start

Electronic components can be easily damaged by electrical surges. Jump starting can damage electronics
and electrical systems, and is not recommended. Try to charge the battery instead. Use quality large
diameter booster cables capable of carrying high currents (400 amps or more). Cheap cables may not
allow enough current flow to charge a dead/discharged battery.

IMPORTANT: Some equipment may have a positive booster cable terminal located externally. If
so equipped, use this terminal instead of connecting directly to battery.

Read all steps thoroughly and review illustration before performing procedure.
