6.  Repair  Precaution  &  Examination

The  primary  complain  occurring  in  the  operation  is  mainly  because  of  mechanical 

parts  and  hydraulic  parts  problem.

Mechanical  difficulties  appears  in  each  boom,  CRACK  occurred  in  other  structures 

and  destroy,  etc,  hydraulic  defects  is  hard  to  find,  so  check  them  well.

A.  Check  Points  before  Operation

  A)    Is  hydraulic  pressure  oil  in  the  oil  tank  sufficient?

          Fill  the  Hydraulic  pressure  oil  less  than  the  minimum.  (In  this  case  less  than  the   

          middle  of    Oil  pressure  gauge  on  the  tank) 

          Inspection  of  Hydraulic  pressure  oil  check  the  outrigger  on  refold.

  B)  Isn't  there  oil  leakage  from  connecting  parts  such  as  hydraulic  pressure  hose,     

        pipe,  valve  or  cylinder? 

        Damage  pipes  and  hoses  need  to  replace,  when  poor  connection  make  it                 

        tighten.

  C)  Is  there  crack  or  damage  of  the  structure?

  D) 

When  the  control  lever  operates  well  and  put  the  lever,  is  it  back  to  neutral  position?

  E)  Is  it  good  to  operate  the  valve,  when  operating  the  remote  control?

  F)  Isn't  there  loose  or  damage  from  connecting  parts,  bearing  and  bushing,  shaft,     

        pin  etc?

  G)  Isn′t  there  damage  of  wires  and  cables?

B.  Check  Points  during  Operation

  A)    Is  there  leakage  of  hydraulic  pressure  oil? 

  B)    Is  there  generation  of  suspicious  noise  during  operation?

  C)    Isn't  the  temperature  of  hydraulic  pressure  oil  very  high?

  D)  During  boom  operation,  does  lifting  of  outrigger  foothold  appear  in                           

          phenomenon?

C.  Check  Points  after  Operation

  A)  Is  the  condition  good  as  much  as  the  next  operation? 

  B)  Is  there  crack  or  damage  of  the  structure?

  C)  Isn't  there  oil  leakage  from  connecting  parts  such  as  hydraulic  pressure  hose,     

        pipe?
