TM 9-2520-238-34 HOW TO USE THIS MANUAL (cont) Before starting, get all tools, supplies, and personnel, listed on the setup page needed to do the WP. Be sure to read the WP before performing the maintenance. If any other WPs are referenced, you must go to the setup page for each of those WPs to find out what tools, parts, and materials will be needed. Start with step 1 and do each step in given order. Look at the illustrations. These show you what to look for when reading a maintenance WP. Maintenance Instructions WPs Doing maintenance WPs will keep the carrier in shape to operate. Maintenance WPs are used to present maintenance instructions. Each maintenance WP details steps which you need to perform. If the carrier and parts need maintenance that is not included in any WP in the manual, report this to your supervisor. Read the INITIAL SETUP section carefully before you start a WP. Get the tools and supplies listed and the personnel needed to perform the WP. Be sure that the equipment is in the condition required. DEFINITION OF WP TERMS WARNINGS, CAUTIONS, AND NOTES Be sure to read all warnings and cautions in the WP. Ignoring a warning could cause death or injury to yourself or other personnel. Ignoring a caution could cause damage to equipment. Notes contain facts to make the WP easier. Warnings, cautions, and notes always appear just above the WP step to which they apply. WARNINGS Call attention to things that could kill or injure personnel. Warnings are also listed in the Warning Summary section (page a). CAUTIONS Call attention to actions or materials that could damage equipment. NOTES Contain important facts to make the procedure easier. HELPER Helpers are needed for WPs that require more that one person such as lifting heavy objects or acting as an observer. If a helper is needed to perform a procedure, the INITIAL SETUP will list “Helper” under the PERSONNEL REQUIRED heading. If helper assists with a step, the step will include: “Have helper assist”. If a helper performs the action alone, the step will start with “HELPER”. REFERENCES References within a WP refer to a different manual or to another WP in the same manual. A step in one WP may be a complete WP someplace else. Below is an example of a reference step from the WP: REPAIR BRAKE SHOE ASSEMBLIES. Example: Check wear limits and clearances of parts, (WP 0021 00). The tools needed to do the task will be listed in that task. MATERIALS/PARTS For all WPs, the following comments apply: Parts which are listed on the setup page will be referred to as “new” in the WP setup when installed. Examples are: “locknuts”, “lockwashers”, “cotter pins”, and some “gaskets”. These and othernew parts are listed under MATERIAL/PARTS in the initial set up. GENERAL MAINTENANCE Cleaning, inspecting, checking for leaks, and similar procedures which apply to most WPs are found in the GENERAL MAINTENANCE PROCEDURES (WP 0014 00). Use these steps to clean and inspect any part being removed, repaired, or installed. Special cleaning will be covered in the WP step. Below is a step that would require general cleaning. vi
