TM 10-4610-243-13 2-7. PMCS PROCEDURES - cont. NOTE Term "ready/available" and "mission capable" refer to the same status: Equipment is on hand and ready to perform its combat missions (See DA Pam 738-750) e. The "EQUII'MENT IS NOT READY/AVAILABLE IF column in Table 2-1 tells you when your equipment is not mission capable and why the system cannot be used. f If the equipment does not perform as required, refer to Chapter 3, Section II, Troubleshooting. g. If anything looks wrong and you can't fix it, write it on your DA Form 2404. IMMEDIATELY, report it to your supervisor. h. The following are checks that are common to the entire water system (1) Keep the equipment clean. Remove dirt, sand and debris from quick disconnect couplings, hose ends, gate valves and distribution nozzles to prevent excessive wear and contamination of the water system Use soap and water to remove dirt Do not contaminate system with any type of cleaning solvent. (2) Bolts, nuts and screws Check them for obvious looseness, missing, bent or broken condition on gate valves If you find a bolt, nut or screw you think is loose, tighten it or report it to your supervisor. (3) Hoses. Look for wear, damage and leaks. Make sure clamps and quick disconnect couplings are tight Wet spots show leaks, but a stain around a fitting or connector can also mean a leak. If a leak comes from a loose fitting or coupling, tighten it. If something is broken or worn out, report it to your supervisor. i. When you check for "operating condition", look at the component to see if it's serviceable. 2-8. LEAKAGE DEFINITIONS FOR OERATOR PMCS.
