OPERATOR MAINTENANCE
PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) INTRODUCTION
GENERAL
PMCS means systematic caring, inspecting, and servicing of equipment to keep it in good condition and to prevent
breakdowns. Always perform the PMCS in the same order, so it gets to be a habit. Once you have had some
practice, you will quickly spot anything wrong. Perform the PMCS as follows:
1. BEFORE PMCS - just before you operate the M48A5 and M60A1 Armored Vehicle Launched Bridge
(AVLB). Pay attention to WARNINGS, CAUTIONS, and NOTES. Refer to WP 0048.
2. DURING PMCS - while you operate the AVLB. During operation means to monitor the AVLB and its related
components while it is actually being operated. Pay attention to WARNINGS, CAUTIONS, and NOTES.
Refer to WP 0048.
3. AFTER PMCS - right after operating the AVLB. Pay attention to WARNINGS, CAUTIONS, and NOTES.
Refer to WP 0048.
4. WEEKLY - once a week. Refer to WP 0048.
5. MONTHLY - once a month. Refer to WP 0048.
Use DA Form 2404 (Equipment Inspection and Maintenance Worksheet) to record any faults that you discover
before, during, or after operation, unless you can fxthem. You DO NOT need to record faults that you f x.
CORROSION PREVENTION AND CONTROL (CPC)
Inspect all external and internal parts and surfaces for corrosion. If corrosion is found, notify f eld maintenance.
Refer to WP 0001 for CPC requirements.
PMCS PROCEDURES
The PMCS table in work package 0048 lists the inspections and care required to keep the AVLB in good operating
condition. It is set up so you can perform BEFORE Operation checks as you walk around the AVLB. The PMCS
table includes the following columns:
1. The ITEM NO. column indicates the number assigned to each PMCS procedure. The procedures are
numbered in logical sequence of performance.
2. The INTERVAL column indicates when to perform a certain check or service.
3. The ITEM TO BE CHECKED OR SERVICED column identif es the vehicle component located where the
procedure is to be performed.
4. The PROCEDURE column indicates how to do the required checks and services. Carefully follow these
instructions. If you do not have tools, or if the procedure tells you to, notify your supervisor.
5. The EQUIPMENT NOT READY/AVAILABLE IF column indicates when the AVLB is non-mission capable
and why the equipment cannot be used.
If the AVLB does not perform as required, refer to Chapter 3, Troubleshooting. Refer to WP 0039. If anything looks
wrong and you cannot f x it, complete a DA Form 2404. IMMEDIATELY report the problem to your supervisor.
