4. Always perform PMCS in the same order so it gets to be a habit. Once you have had some practice, you will spot anything wrong in a hurry. If the equipment does not perform as required, refer to the appropriate trouble-shooting procedure in Chapter 3.
5. If anything looks wrong and you cannot fix it, write it on your DA Form 2404 or DA Form 5988-E. If you find something seriously wrong, IMMEDIATELY notify Field Maintenance.
6. Before performing PMCS, read all the checks required for the applicable interval and prepare all that is needed to make all the checks. You will always need a rag (WP 0022, Item 19)or two.
WARNING
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low-toxicity material. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in well-ventilated areas. Keep away from open flames and other sources of ignition. Failure to follow this warning may result in injury or death to personnel.
CAUTION
Be especially careful when cleaning electrical system components, including lighting.
Damage or impaired operation could result if this caution is not observed.
a. Keep Equipment Clean. Dirt, grease, oil, and debris may cover up a serious problem. Clean as you work and as needed. Use cleaning compound, solvent, type III (WP 0022, Item 3) on all metal surfaces. Use detergent, general purpose, liquid (WP 0022, Item 5) and water when you clean rubber, plastic, and painted surfaces. Spot paint as required to prevent corrosion.
b. Hazardous Waste Disposal. Ensure all spills are cleaned up and disposed of IAW local policy and ordinances.
c. Rust and Corrosion. Check metal parts for rust and corrosion. If any bare metal or corrosion exists, clean and apply light coating of oil, lubricating preservative, corrosion inhibitor (WP 0022, Item 17), and notify Field Maintenance.
d. Bolts, Nuts, and Screws. Ensure that they are not loose, missing, bent, or broken. Report loose, missing, or damaged bolts, nuts, and screws to Field Maintenance.
e. Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. Report bad welds to Field Maintenance.
f. Electrical Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or broken connectors. Report loose connections and faulty wiring to Field Maintenance.
g. Hoses, Lines, and Fittings. Look for wear and damage. Check for loose clamps and fittings. Report any worn, damaged, or loose hoses, lines, and fittings to Field Maintenance.
h. Fluid Leakage. It is necessary for you to know how fluid leakage affects the status of your machine. The following are definitions of the types, or classes, of leaks you need to know to determine the status of your machine. Learn and be familiar with them, and remember, when in doubt, notify Field Maintenance.

GENERAL PMCS PROCEDURES – CONTINUED
CAUTION
EXCEPT FOR ANY TYPE OF FUEL OR COOLANT LEAK, operation is allowable with Class I and Class II leakage. WHEN IN DOUBT, NOTIFY FIELD MAINTENANCE. When operating with Class I or Class II leaks, check fluid levels more frequently. Any type of fuel or coolant leak, or any Class III leaks, must be reported immediately to Field Maintenance.
Failure to do this will result in damage to machine and/or components.
NOTE
• Notify Field Maintenance of any leaks you cannot fix.
• Use a drain pan to collect draining or leaking fluid. Dispose of all fluids IAW Unit SOP.
• Contain and clean up any spilled or leaked fluids IAW Unit SOP.
LUBRICATION PROCEDURES 00011
NOTE
• Refer to Lubrication Order 5-2410-241-13 for tables, localized views, and procedural notes.
• While reading this manual, keep in mind that right and left designations are as if you were sitting in the operator’s seat.
1. Recommended intervals are based on normal conditions of operation, temperature, and humidity. When operating under extreme conditions, lubricants should always be changed more frequently. When in doubt, notify Field Maintenance.
2. Keep all lubricants in a closed container and store in a clean, dry place away from extreme heat or cold. Keep container covers clean and DO NOT allow dust, dirt, or other foreign material to mix with lubricants. Keep all lubrication equipment clean and ready for use. All stored lubricants must be properly labeled and IAW hazmat requirements.
3. Maintain a good record of all lubrication performed and report any problems noted during lubrication. Refer to PAM 750-8 for maintenance forms and procedures to record and report any findings.
4. Keep all external parts of equipment not requiring lubrication free of lubricants. Before lubrication, wipe lubrication fittings with a clean rag (WP 0022, Item 19). After lubrication, wipe off excess oil or grease to prevent accumulation of foreign matter.
5. Refer to FM 9-207 for lubrication instructions in cold weather.
6. Refer to AR 70-12 for use of standardized lubricants.
