OPERATOR/CREW PREVENTIVE MAINTENANCE
CHECKS AND SERVICES (PMCS)--Continued
GENERAL PMCS PROCEDURES
Solvents can burn easily, can give off harmful vapors, and are
harmful to skin and clothing. To avoid injury or death, keep away
from open fire and use in a well-ventilated area. If solvent gets on
skin or clothing, wash immediately with soap and water.
Keep equipment clean. Dirt, oil, and debris may cover up a serious problem. Clean as you work and as
needed. Use cleaning compound on all metal surfaces. Use solution of soap and water on rubber, plastic,
and painted surfaces.
While performing PMCS, inspect the following components:
Bolts, Nuts, and Screws. Make sure they are not loose, missing, bent, or broken. Tighten any that are
Welds. Inspect for gaps where parts are welded together. Report bad welds to your supervisor.
Electrical Wires or Connectors. Inspect for cracked or broken insulation, bare wires, and loose or
broken connectors. Report defects to your supervisor.
Hoses, Lines, and Fittings. Inspect for wear, damage, and leaks. Make sure clamps and fittings are
tight. If leak originates from a loose fitting or connector, tighten it. If not authorized, report it to your
SPECIFIC PMCS PROCEDURES
Operator PMCS procedures are listed in Table 1. Always perform PMCS procedures in the order listed.
Once this becomes a habit, you will spot anything that is not right in a minute. If anything wrong is
discovered through PMCS, perform the appropriate troubleshooting task. If any component or system is
not serviceable, or if the service given does not correct the problem, notify your supervisor.
Before performing PMCS, read all the checks required for the applicable interval and prepare the tools
needed to make all the checks.
The column headings in Table 1 are defined as follows:
Item No. The item number column of your PMCS table is to be used for reference. When completing DA
Form 2404 or DA Form 5988-E, include the item number for the checks and services indicating a fault.
Item numbers also appear in the order that you must do the checks and services for the intervals listed.
Interval. This column tells you when to do a certain check or service. Special intervals will also be
specified (e.g., every 100 hours) when the component requires service more frequently than
semiannually or annually.
Item To Be Inspected. This column tells you what item is to be inspected and how to do the required
checks and services. Carefully follow these instructions. If you do not have the tools, or if the procedure
tells you to, have Organizational maintenance do the work.
