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.

Inspect Site
Inspect Site
Inspect jobsite before transporting equipment. Check for the following:
•
changes in elevation such as hills or other open trenches
•
obstacles such as buildings, railroad crossings, or streams
•
signs of utilities (“Inspect Jobsite” on page 74)
•
traffic
•
access
•
soil type and condition
Identify Hazards
Identify safety hazards and classify jobsite. See “Classify Jobsite” on page 74.
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.

•
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
Crystalline silica dust is a naturally occuring substance found in soil, sand, concrete, granite, and quartz.
Breathing silica dust particles while cutting, drilling, or working materials may cause lung disease or
cancer. To reduce exposure:
•
Use water spray or other means to control dust.
•
Refer to U.S. Department of Labor Occupational Safety and Health Administration guidelines to learn
more about appropriate breathing protection and permissible exposure limits.
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
Safe Slope Operation
Tipover possible. Machine can tip over and crush you.
To help avoid injury:
• Always operate with heavy end uphill.
• Drive cautiously 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.
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.

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 “Check Digging Chain
Tension” on page 155.
•
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.

The engine is this unit 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
engine operation manual for more information.
IMPORTANT: 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 using fuel with sulfur
content above 5000 ppm (0.05%, low sulfur diesel in the U.S.), reduce oil change interval by half.
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. 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.

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

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.
