OPERATOR MAINTENANCE
GENERAL INFORMATION
SCOPE
This manual contains instructions for operation, operator troubleshooting, and operator-performed maintenance on
the Hydraulic Excavator Type 1 (HYEX). The HYEX is used for construction operations.
MAINTENANCE FORMS AND RECORDS
Department of the Army forms and procedures used for equipment maintenance will be those prescribed by (as
applicable) DA PAM 750-8, The Army Maintenance Management System (TAMMS) Users Manual (WP 0094); or
AR 700-138, Army Logistics Readiness and Sustainability (WP 0094).
REPORTING EQUIPMENT IMPROVEMENT RECOMMENDATIONS (EIR)
If your HYEX needs improvement, let us know. Send us an EIR. You, the user, are the only one who can tell us what
you don't like about your equipment. Let us know why you don't like the design or performance. If you have Internet
access, the easiest and fastest way to report problems or suggestions is to go to https://aeps.ria.army.mil/
aespublic.cfm (scroll down and choose "Submit Quality Deficiency Report" bar). The internet form lets you choose
to submit an EIR, a Product Quality Deficiency Report (PDQR) or a Warranty Claim Action (WCA). You may also
submit your information using an SF Form 368 (Product Quality Deficiency Report). You can send your SF Form
368 via e-mail, regular mail, or facsimile using the addresses/facsimile numbers specified in DA PAM 750-8, The
Army Maintenance Management System (TAMMS) Users Manual (WP 0094), and mail it to us at: Department of
the Army, U.S. Army Tank-Automotive and Armaments Command, AMSRD-TAR-E, PDQR MS 268, 6501 E. 11 Mile
Road, Warren, MI 38397-5000. We will send you a reply.
CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (CPC) of Army materials is a continuing concern. It is important that any corrosion
problems with the HYEX be reported so that the problem can be corrected and improvements can be made to prevent
the problem in the future. While corrosion is typically associated with rusting of metals, corrosion can also include
deterioration of other materials, such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of
these materials may be a corrosion problem. If a corrosion problem is identified, it can be reported using Standard
Form 368, Product Quality Deficiency report (WP 0094). Use of key words, such as corrosion, rust, deterioration,
and cracking, will ensure that the information is identified as a CPC problem.
DESTRUCTION OF ARMY MATERIAL TO PREVENT ENEMY USE
For procedures to destroy the HYEX to prevent its use by the enemy, refer to TM 750-244-6, Procedures for
Destruction of Tank-Automotive Equipment to Prevent Enemy Use (WP 0094).
PREPARATION FOR STORAGE OR SHIPMENT
Contact Field Maintenance for instructions on preparation for storage or shipment.
