OPERATOR'S PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)

INTRODUCTION

This work package contains Operator's PMCS requirements for the PLS AC system. The PMCS table in this work

package contains checks and services necessary to ensure that the AC system is ready for operation. Using

PMCS tables, perform maintenance at specified intervals. Perform PMCS listed in TM 9-2320-364-10, before

performing these PMCS checks.

GENERAL MAINTENANCE PROCEDURES

a. Cleanliness.

Dirt, grease, oil, and debris may cause or cover a serious problem. Clean all metal surfaces.

b. Bolts, nuts, and screws. Check bolts, nuts, and screws for obvious looseness, missing, bent, or broken

condition. Look for chipped paint, bare metal, or rust around boltheads. If any part seems loose, tighten it, or have

the part repaired or replaced.

c. Welds.

Look for loose or chipped paint, rust, or gaps on welds. If a bad weld is found, notify Field Level

Maintenance.

d. Electrical wires and connectors. Look for cracked or broken insulation, bare wires, and loose or broken

connectors. Tighten loose connectors and make sure wires are in good shape. If a wire or connector is bad, notify

Field Level Maintenance.

e. AC system leaks. Look for air conditioner lubrication leakage and corrosion, and damage to fittings,

hoses, and other components. Inspect lowest points of fittings, and hoses for indication of lubrication leakage.

If lubrication leakage is found, notify Field Level Maintenance.

NOTE

Always observe the warnings and cautions appearing in your PMCS table. Warnings and

cautions appear before applicable procedures. You must observe these warnings and

cautions to prevent serious injury to yourself and others or prevent equipment from being

damaged.
