TM 10-3930-653-14&P MAINTENANCE SECTION (PREVENTIVE) DAILY CHECKS BEFORE OPERATION CHECK TO BE SURE THAT ANY PREVIOUS FAILURES HAVE BEEN CORRECTED. If at any time a powered industrial truck is found to be in need  of  repair,    defective,    or    in    any    way  unsafe,  the matter    should    be    reported    immediately        to        the designated  authority,  and  the  truck  should  be  taken  out of  service  until  it  has  been  restored  t,,  safe  operating condition. CAUTION Don’t   make   repairs   or   adjustments unless   specifically   authorized   to   do so. CHECK LEAKS OF OIL, FUEL OR WATER Check joints of the hydraulic piping, engine, radiator and driving system for  oil  and  water  leaks.  Check leakage with your finger as well as visually. CAUTION Do not attempt to operate the truck if leaked fuel is found during preoperational      check.      Correct   the leak before starting the engine. HUB NUT TORQUE CHECK Check  hub  nuts  for  correct  torque.    All  hub  nuts  should be tightened to the specified torque securely. TIRE INFLATION PRESSURE CHECK Check  condition of  tires.  Low air pressure reduces tire service life and increases fuel consumption. Unevenness  of  air  pressure  between  right  and  left  tires or  unevenly  worn  or   badly   damaged   tires      will   cause uneven steering forces. WARNING All nuts and bolts should be properly installed and torqued before inflating  tire and rim    assembly. An   inflated   tire   contains   potentially explosive energy. DON’T OVERINFLATE. WARNING When  using  an  air  compressor,  first adjust the air pressure of the compressor.      Failure   to   do   so   will cause  a  serious  accident,   since   the compressor    delivers    the    maximum pressure. The  standard  tire  pressures are indicated below: (Inflation Pressure)  [kg/cm2 (psi)] Drive Wheels ....................................................... 7 (100) Steering Wheels....................................................7 (100’ Turn  the tire valve cap counterclockwise and remove it. Using    a    tire    pressure    gauge,    measure    the    inflation pressure,   and   adjust   it   to   the   specified   pressure,   if needed. After making sure there is no air leakage  from  the  tire valve, reinstall the cap. Check that each tire is not damaged at the tread surface or side face or bending at the rim. Since   the   forklift   truck   needs   tires   that   have   a   high inflation pressure to carry  heavy  loads,  even  a  small bending  of  rims  or  damage  at  the  tread  surface  could cause  an    accident.    If  the  operator  finds  any  defect  in the tires, consult your Supervisor. 3-1
