TM 10-3930-659-10 2-7.  GENERAL PMCS PROCEDURES (Con’t). (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 Unit Maintenance. (5)    Electric  Wires  and  Connectors.    Look  for  cracked  or  broken  insulation,  bare  wires,  and  loose  or  broken connectors.  Tighten loose connectors and ensure that the wires are In good condition. (6)  Air and 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, report it to Unit Maintenance. (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 the status of your forklift truck.  Learn and be familiar with them, and remember - when in doubt, notify your supervisor! Leakage Definitions for Operator/Crew PMCS Class I Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops. Class II 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. CAUTION When  operating  with  Class  I  or  II  leaks,  continue  to  check  fluid levels In addition to that required In PMCS.  Parts without fluid will stop working or may be damaged. (a) Equipment operation is allowable with minor (Class I or 11) 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. (b) IMMEDIATELY report Class III leaks to Unit Maintenance. 2-13
