FOREWORD___________ 3 This manual contains illustrated parts lists to help you select quality ProTech ® Replacement parts for your Ditch Witch ® equipment. Using other replacement parts will lessen the productivity of your equipment. Part numbers enclosed in a box are no longer available from The Charles Machine Works, Inc. Your local Ditch Witch dealer may be able to locate the part for you. Footnotes provide more information to help you identify parts shown in the manual. Assembly instructions and Tech Bits articles referenced in footnotes are available through your local Ditch Witch dealer. Description and specifications in this book were current at publication.

However, The Charles Machine Works, Inc. reserves the right to improve equipment, so this manual might not reflect the most current improvements. Instructions on recommended equipment use and maintenance are in the Operator’s Manual that was shipped with your equipment. Keep the following in mind when ordering ProTech replacement parts: Specify parts you need by part number and description, not by illustration reference numbers. Have equipment model and serial number on hand to help ensure you get the right parts for your machine whether it’s old or new. Thank you for buying and using Ditch Witch equipment and ProTech replacement parts. 8/6/2010, Rev-B 800-001
