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.

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.

HT115 Tier 3 Operator’s Manual
AutoTrack
AutoTrack
Overview
The HT115 ground drive is a computer-controlled speed/direction system. A variety of sensors send input
data to an ECU (Electronic Control Unit) that compares inputs with pre-programmed memory and sends
output voltage to a variety of actuators to adjust and operate the tractor speed and direction within
specified parameters.
The AutoTrack feature allows the operator to save a set of input control settings. These settings maintain
the speed/direction outputs for hands-free operation. Settings can be temporarily overridden by the
joystick or changed during operation by using the speed switch and/or steering switches.
AutoTrack controls include:
•
ground drive joystick
•
trigger switch
•
speed switch (resume/set)
•
steering selector switch (left/right)
The cruise control indicator on the front console illuminates to tell the operator when the AutoTrack system
is activated. The indicator flashes to alert the operator to an error in the ground drive control system.
Direction and speed can be controlled by the ground drive joystick and by speed and steering switches. To
turn, move the joystick left or right from neutral while traveling. Turning radius decreases as the joystick is
moved farther from neutral. When AutoTrack is not activated, moving the ground drive joystick beyond 2/3
of full travel to either side of neutral causes the track on the inside of the turn to counter-rotate (moves at
the same speed as the outside track but in the opposite direction).
When the joystick is returned to neutral while driving, tractor will derate and stop.
AutoTrack can be activated while the tractor is stationary by pulling and holding the set switch or trigger
switch on the joystick, and moving the joystick forward. When the cruise control indicator lights, release set
switch and return joystick to neutral. The tractor will not move until the RESUME switch (increase speed) is
pressed and held. Release the switch when the desired speed is reached. Steering can be adjusted by
pressing the steering switches. Release the switch when the tractor is turning as desired.
To activate AutoTrack while moving, move the joystick until the desired speed and direction are achieved,
press and release the set switch, and return the joystick to neutral. Speed and direction can be adjusted
while moving by using the speed switch and steering switches.
To temporarily increase speed or change direction while AutoTrack is activated, move the joystick to the
desired settings. Return the joystick to neutral to return to previous speed and degree of turn.
Deactivate AutoTrack by pulling the joystick back, past neutral (reverse direction), then back to neutral.
After deactivating AutoTrack, (when ignition has not been switched off), you can reactivate AutoTrack
using existing settings by pressing and holding the RESUME switch and moving the joystick forward out of
neutral. The tractor will return to the previously established settings.

AutoTrack
Operate AutoTrack
EMERGENCY SHUTDOWN - Turn ignition switch to stop position.
1. Following procedures in “Operation” on page 93, begin plowing to desired depth.
2. When desired depth is reached, ensure throttle is fully open.
3. Adjust ground drive speed to match digging conditions.
4. To activate AutoTrack while moving, move the joystick until the desired speed and path are achieved,
press and release the set switch, and return the joystick to neutral. Speed and direction can be
adjusted while moving by using the speed switch and steering switches.
5. To deactivate AutoTrack and stop tractor, momentarily pull joystick to reverse.
Stopping
The tractor will decelerate and stop when:
•
joystick is returned to neutral while AutoTrack is not activated
•
joystick is pulled past neutral (in reverse) when AutoTrack is activated
•
operator leaves the seat
•
parking brake switch is moved to the on position
The HT115 parking brake is automatically applied whenever the joystick is in neutral and AutoTrack is not
active (cruise control indicator is not lit), or when the operator is not in the seat.
NOTICE: The parking brake indicator does not light for this automatic function.
Pressing the parking brake switch engages and locks the brake, lights the parking brake indicator, and
causes the joystick and AutoTrack switch inputs to be ignored.

HT115 Tier 3 Operator’s Manual
AutoTrack
Ground Drive Diagnostics
The HT115 Tier 3 AutoTrack ground drive system uses hydraulic valves actuated by electrical solenoids
energized by output voltage from the machine controller. The system is self-diagnostic. The cruise control
indicator flashes to alert the operator to a ground drive control system error. An electronic diagnostic tool
(EDT) can be used to view system faults and perform diagnostics. Accumulated codes can be retrieved
only by dealership service technicians with this specialized electronic equipment.
Should a fault occur, the cruise indicator will flash on and off for 10 seconds, then return to either on or off,
depending upon whether AutoTrack is activated. If the ignition key is turned off, all faults are cleared. The
next time the controller is powered up the indicator will resume normal operation until a new fault is
detected.
IMPORTANT: Contact your Ditch Witch dealer if the cruise indicator starts flashing.

Tier 3 Engine
Tier 3 Engine
Overview
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.
Diagnostic Codes
When a monitored fault condition occurs in the Tier 3 system, diagnostic codes are displayed on the
tachometer/diagnostic gauge or read directly from the diagnostic connector located on the rear console.
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
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 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.
IMPORTANT:
•
For more information on the operator alert indicator and how to operate and read the diagnostic
gauge, see “Indicators” on page 24.
•
For an explanation and interpretation of codes, see “Tier 3 Engine Diagnostic Codes” on page 185.

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.
•
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.

AutoTrack Diagnostics
AutoTrack Diagnostics
The HT115 Tier 3 AutoTrack ground drive system uses hydraulic valves actuated by electrical solenoids
energized by output voltage from the machine controller. The system is self-diagnostic. The cruise control
indicator flashes to alert the operator to a ground drive control system error. An electronic diagnostic tool
(EDT) can be used to view system faults and perform diagnostics. Accumulated codes can be retrieved
only by dealership service technicians with this specialized electronic equipment.
Should a fault occur, the cruise indicator will flash on and off for 10 seconds, then return to either on or off,
depending upon whether AutoTrack is activated. If the ignition key is turned off, all faults are cleared. The
next time the controller is powered up the indicator will resume normal operation until a new fault is
detected.
IMPORTANT: Contact your Ditch Witch dealer if the cruise indicator starts flashing.
Tier 3 Engine Diagnostic Codes
The 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.
To read a step-by-step troubleshooting sequence for each code, see repair guide.

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.
