TM 10-3930-659-20 3-6. GENERAL PMCS PROCEDURES (Con't). (3) Bolts,  Nuts,  and  Screws.    Check  bolts,  nuts,  and  screws  for  obvious  looseness,  missing,  bent,  or broken condition.  You can't try them all with a tool, of course, but look for chipped paint, bare metal, or rust around bolt heads.  If you find one you think is loose, tighten it. (4) Welds.  Look for loose or chipped paint, rust, or gaps where parts are welded together.  If you find a bad weld, report it to your supervisor. (5) Electrical  Wires  and  Connectors.    Look  for  cracked  or  broken  insulation,  bare  wires,  and  loose  or broken connectors.  Tighten loose connectors and ensure that wires are In good condition. (6) Hydraulic  Hoses  and  Lines.    Look  for  wear,  damage,  and  signs  of  leaks.    Ensure  that  clamps  and fittings are tight.  Wet spots indicate leaks, of course, but a stain around a fitting or connector can also mean a leak.  If a leak comes from a loose fitting or connector, tighten it.  If something is broken or worn out, correct it if authorized by the Maintenance Allocation Chart (Appendix B).  If not authorized, report it to your supervisor. (7) Fluid  Leakage.    It  is  necessary  for  you  to  know  how  fluid  leakage  affects  the  status  of  your  forklift truck.  The following are definitions of the types/classes of leakage you need to know to be able to determine whether the forklift truck is mission-capable.  Learn and be familiar with them, and remember - when in doubt, notify your supervisor! CAUTION Equipment operation Is allowable with minor (Class I or II) leakage.  Fluid levels In an Item/system affected with such leakage must be checked more frequently than required In PMCS.  When In doubt, notify your supervisor.  IMMEDIATELY report Class III leaks to your supervisor. Leakage Definitions for Unit PMCS Class I Seepage of fluid (as Indicated by wetness or discoloration) not great enough to form drops. Class I Leakage of fluid great enough to form drops, but not enough to cause drops to drip from the item being inspected. Class III Leakage  of  fluid  great  enough  to  form  drops  that  fall  from  the  item  being inspected. 3-3
