TM 9-2350-267-10 LOOSE, DAMAGED OR MISSING BOLTS, NUTS AND SCREWS. Check for obvious looseness or damaged condition. Without using a wrench, it maybe difficult to spot loose hardware. However, you can often identify loose bolts by chipped or missing paint around the bolt head and bare metal at the base of the bolt head. If you find a loose bolt, tighten it. If a bolt is missing, or if a dam- aged bolt, nut or screw is discovered, report it to Organizational Maintenance. FRAYED ELECTRICAL WIRES AND LOOSE CONNECTORS. Electrical wiring should be checked for cracks due to aging or adverse weather condi- tions. Tighten loose clamps and connectors. If exposed wiring or damaged connectors are discovered, notify Organizational Maintenance. FLUID LEAKS. Look for wear, damage and leaks under fluid hoses, lines and fittings. Make sure fittings and clamps are tight. Wet spots indicate leaks but stains around a fitting can mean a leak too. If a leak comes from a loose fitting or connector, tighten the connection. If a hose, fitting orconnectoris broken or worn out, report it to Organizational Maintenance. It is necessary for you to know how fluid leakage affects your vehicle. The following classi- fication system defines the three types of leaks you will encounter while doing PMCS. Be- come familiar with the system so that you can determine the readiness status of your vehi- cle. CLASS I LEAK - Seepage of fluid (indicated by wetness or discoloration) not great enough to form drops. CLASS II LEAK - Leakage of fluid great enough to form drops, but not enough to cause drops to drip from the item being checked/inspected. CLASS Ill LEAK - Leakage of fluid great enough to form drops that fall from the item being checked/inspected. CAUTION Equipment operation is allowable with minor leak- age (Class I or Class II). Of course, consideration must be given to the fluid capacity In the item/sys- tem being checked/inspected. When in doubt notify your supervisor. When operating with Class I or Class II leaks, continue to check fluid levels as re- quired in your PMCS. Class Ill leaks should be reported to your supervisor or Organizational Maintenance. 2-26
