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.

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
Jobsite hazards could cause death or serious injury. Use correct
equipment and work methods. Use and maintain proper safety equipment.
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..
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.

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 – 30°
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.

4. Slowly back up tractor while maintaining rotation.
5. When backreamer exits the bore hole, stop rotation immediately.
IMPORTANT:
CMW
•
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.

Cruise Control
Cruise Control
Cruise control is a standard feature that allows the unit to automatically adjust ground drive speed
according to digging conditions. In easier soil conditions, the ground drive speed will increase. When the
unit encounters difficult soil conditions, the ground drive speed will decrease. The unit does this by
adjusting ground drive pump output to maintain a preset engine speed.
Operate Cruise Control
EMERGENCY SHUTDOWN - Turn ignition switch to STOP.

Trench Depth Meter
Trench Depth Meter
Trench Depth Meter (TDM) is an optional electronic system for measuring and recording trench depth.
TDM also displays productivity and distance while trenching. Two lines of information are displayed on the
LED screen. If the system detects error conditions, diagnostic codes will be displayed on the second line.
IMPORTANT: For more information about TDM see the TDM Operator’s Manual (p/n 054-117).
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 136.
•
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.

Tier 3 Engine
Tier 3 Engine
Tier 3 is a computer-controlled fuel management system. A variety of sensors send input data to an ECU
(Electronic Control Unit) that compares inputs with pre-programed memory and sends output voltage to a
variety of actuators to adjust and operate the engine within specified parameters.
The system is self-diagnostic with stored trouble codes displayed on the tachometer/diagnostic gauge or
read directly from a diagnostic connector. For more information about the diagnostic system and trouble
codes see "Troubleshooting" in the repair guide.
An operator alert indicator tells the operator when warning faults or engine shutdown faults develop.
Warning faults occur when engine sensors indicate moderate trouble with coolant temperature, oil
pressure, charge air temperature, or fuel temperature. Warning faults cause the operator alert indicator to
flash, and the engine will begin a slow power derate. In some situations an alarm may also sound. A
trouble code is stored in the ECU. If the fault corrects itself, the engine will gradually return to normal
power. The alert indicator will continue to flash until the trouble goes away, but a trouble code will remain
stored.
Engine shutdown will occur due to severe faults in engine coolant temperature, oil pressure, or fuel
temperature. Before shutdown, the operator alert indicator will light continuously and the engine will begin
a rapid power derate. If the fault does not improve in 30 seconds the engine will shut down.
Engine Diagnostic Codes
Problems with the Tier 3 engine usually are indicated by the operator alert indicator and by a diagnostic
code displayed on the tachometer/hourmeter/diagnostic gauge.
RT115Q Operator’s Manual
Tier 3 Engine
Operator Alert Indicator
When a non-critical engine fault occurs, the operator alert indicator on the
gauge cluster will light. A fault code will be stored in the diagnostic gauge.
Engine Shutdown Indicator
When an critical engine fault occurs, the engine shutdown indicator will
light. A fault code will be stored in the diagnostic gauge, and the engine will
shut down within 30 seconds.

Ditch Witch Equipment and Replacement Parts
Limited Warranty Policy
Subject to the limitation and exclusions herein, free replacement parts will be provided at any authorized Ditch Witch dealership for
any Ditch Witch equipment or parts manufactured by The Charles Machine Works, Inc. (CMW) that fail due to a defect in material or
workmanship within one (1) year of first commercial use (Exception: 2 years for all SK5 attachments). Free labor will be provided at
any authorized Ditch Witch dealership for installation of parts under this warranty during the first year following “initial commercial”
use of the serial-numbered Ditch Witch equipment on which it is installed. The customer is responsible for transporting their
equipment to an authorized Ditch Witch dealership for all warranty work.
Exclusions from Product Warranty
•
All incidental or consequential damages.
•
All defects, damages, or injuries caused by misuse, abuse, improper installation, alteration, neglect, or uses other than those for
which products were intended.
•
All defects, damages, or injuries caused by improper training, operation, or servicing of products in a manner inconsistent with
manufacturer’s recommendations.
•
All engines and engine accessories (these are covered by original manufacturer’s warranty).
•
Tires, belts, and other parts which may be subject to another manufacturer’s warranty (such warranty will be available to
purchaser).
•
ALL IMPLIED WARRANTIES NOT EXPRESSLY STATED HEREIN, INCLUDING ANY WARRANTY OF FITNESS FOR A
PARTICULAR PURPOSE AND MERCHANTABILITY.
IF THE PRODUCTS ARE PURCHASED FOR COMMERCIAL PURPOSES, AS DEFINED BY THE UNIFORM COMMERCIAL
CODE, THEN THERE ARE NO WARRANTIES WHICH EXTEND BEYOND THE FACE HEREOF AND THERE ARE NO IMPLIED
WARRANTIES OF ANY KIND WHICH EXTEND TO A COMMERCIAL BUYER. ALL OTHER PROVISIONS OF THIS LIMITED
WARRANTY APPLY INCLUDING THE DUTIES IMPOSED.
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.
For information regarding this limited warranty, contact CMW’s Product Support department, P.O. Box 66, Perry, OK 73077-0066, or
contact your local Ditch Witch dealer.
