TM 9-2330-392-14&P Section V. GENERAL MAINTENANCE INSTRUCTIONS 4-15. GENERAL. a. These general maintenance instructions contain general shop practices and specific procedures you must be familiar with to properly maintain the trailer. You should read and understand these practices and procedures before performing any maintenance procedures. b. Before beginning a task, find out how much repair, modification, or replacement is needed to fix the equipment. Sometimes the reason for equipment failure can be seen night away, and complete tear-down is not necessary. Disassemble equipment only as far as necessary to repair or replace damaged parts. c. In some cases, a part may be damaged by removal. If the part appears to be good, and other parts behind it are not defective, leave it on and continue with the procedure. Here are a few simple rules: (1) Do not remove dowel pins or studs unless loose, bent, broken, or otherwise damaged. (2) Do not remove bearings or bushings unless damaged. If you need to remove them to access parts behind, carefully pull out bearings and bushings. (3) Replace all gaskets, lockwashers, self-locking nuts, seals, cotter pins, and performed packings. d. The following ’Initial Setup" information applies to all procedures: (1) “Equipment Conditions" must be performed prior to performing the maintenance task. (2) Resources are not listed unless they apply to the procedure. e. All tags and forms attached to the equipment must be checked to learn the reason for removal of equipment from service. Modification Work Orders (MWOs) and Technical Bulletins (TBs) must be checked for equipment changes and updates. f. Work Safety (1) Observe all WARNINGs and CAUTIONs. (2) Before beginning a procedure, think about the safety risks and hazards to yourself and others. Wear protective gear such as safety goggles or lenses, safety shoes, rubber apron, gloves, and breathing mask when instructed to do so. (3) Immediately clean up spilled fluids to avoid slipping. (4) When lifting heavy objects, have someone help you. Ensure that lifting equipment or jack is working properly, that it meets weight requirements of part being lifted, and that it is securely fastened to part. (5) Always use power tools carefully. 4-17
