Intended Use
Intended Use
Ditch Witch pipe bursters are intended for the replacement of buried pipes and conduits. The PR95
produces 187,400 lb (88 t) of pullback force. A power unit provides hydraulic power to run the pipe burster.
The unit is designed for operation in temperatures typically experienced in earth moving and construction
work environments. Provisions may be required to operate in extreme temperatures. Contact your Ditch
Witch dealer.
Ditch Witch pipe bursters and power units should be operated, serviced, and repaired only by persons
familiar with their particular characteristics and acquainted with the relevant safety procedures.
Use in any other way is considered contrary to the intended use.

Safety Alert Classifications
Safety Alert Classifications
These classifications and the icons defined on the following pages work together to alert you to situations
which could be harmful to you, jobsite bystanders or your equipment. When you see these words and
icons in the book or on the machine, carefully read and follow all instructions. YOUR SAFETY IS AT
STAKE.
Watch for the three safety alert levels: DANGER, WARNING and CAUTION. Learn what each level
means.
indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury.
indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.
indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury.
Watch for two other words: NOTICE and IMPORTANT.
NOTICE can keep you from doing something that might damage the machine or someone's property. It
can also alert you against unsafe practices.
IMPORTANT can help you do a better job or make your job easier in some way.

Emergency Procedures
Emergency Procedures
Before operating any equipment, review emergency proc edures and check that all safety precau tions have
been taken.
EMERGENCY SHUTDOWN - Turn ignition switch to stop position or push remote engine stop button.
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. Almost one-third of 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.

Gather Information
Gather Information
A successful job begins before the burst. 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 ha ve take n enlargement during pullback into a ccount.
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
Call area One-Call or similar services and have existing lines located and marked. Call any utilities in your
area that do not subscribe to One-Call.
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 informa tion. 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.

Jobsite hazards could cause death or serious injury. Use
correct equipment and work methods. Use and maintain proper safety
equipment.
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 bursting.
• Verify location of previously marked underground hazards.
• Mark jobsite clearly and keep spectators away.

Select Exit and Burster Pit Locations
Consider the following when selecting pit locations:
Traffic
Vehicle and pedestrian traffic must be a safe distance from bursting equipment. Allow at least 10’ (3 m)
buffer zone around equipment.
Space
Check that starting and ending points allow enough space for exit and burster pits.
Check that exit area has enough space for product to be installed.
Check that there is enough space to work.

Plan Burst Path
Plan Burst Path
Plan the burst path, from entry to end, before job b egins . Locate the en tire rou te of the pi pe to be replaced
to ensure a straight path. Expose all crossing or parallel utilities within 18” (500 mm) of the pipe being
burst. Visually verify that bursting head does not damage utility.
Prepare Jobsite
Jobsite hazards could cause death or serious injury. Use
correct equipment and work methods. Use and maintain proper safety
equipment.
NOTICE:
• 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.

Ditch Witch products have been tested to deliver acceptable performance in most conditions. This does not imply they will deliver
acceptable performance in all conditions. Therefore, to assure suitability, products should be operated under anticipated working
conditions prior to purchase.
Defects will be determined by an inspection within thirty (30) days of the date of failure of the product or part by CMW or its authorized
dealer. CMW will provide the location of its inspection facilities or its nearest authorized dealer upon inquiry. CMW reserves the right
to supply remanufactured replacements parts under this warranty as it deems appropriate.
Extended warranties are available upon request from your local Ditch Witch dealer or CMW.
Some states do not allow exclusion or limitation of incidental or consequential damages, so above limitation of exclusion may not
apply. Further, some states do not allow exclusion of or limitation of how long an implied warranty lasts, so the above limitation may
not apply. This limited warranty gives product owner specific legal rights and the product owner may also have other rights which vary
from state to state.
