The   dispatcher   normally   maintains   a   Heavy Equipment  Dispatcher’s  Log,  a  class  C  assigned Dispatcher’s  Log,  and  a  class  B  assigned  Dispatcher’s Log.  The  heavy  equipment  log  is  used  for  dispatching construction and weight-handling equipment, the class C   log   is   used   for   dispatching   automotive   and material-handling  equipment,  and  the  class  B  assigned log  is  used  to  record  dispatched  class  B  assigned vehicles. Vehicles assignments are divided into three dispatch categories: class A, class B, and class C. The  class  A  dispatch  category  is  the  full-time assignment of a vehicle to an individual that is only authorized by the Chief of Naval Operations (CNO). The class B dispatch category in the NCF is the once a week assignment of a vehicle that requires a DD Form 1970.  The  class  B  assignment  in  an  NMCB  is recommended  by  the  equipment  officer  and  approved by the commanding officer. The class C dispatch category covers all equipment not under class A or class B. Class C assignments are made on an “as-needed” basis. However, members and project  crews  are  normally  assigned  the  same  vehicle each day. The heavy equipment and class C logs are closed out daily, and the class B assigned log, in an NMCB, is closed out weekly. Closing out a log is done by adding all the ending mileage and hour meter readings and enclosing the reports and records inside the appropriate folded Dispatcher’s Log. On the outside of the log, the dispatcher records the date, total mileage, and total operating  hours  of  all  the  equipment  dispatched. On  the  first  work  day  of  each  week,  the transportation  supervisor  collects  the  Dispatcher’s  Logs for the Alfa company operations supervisor so they can be  reviewed  as  required  by  the  COMSECOND/ COMTHIRDNCBINST  11200.1  Series. In the NCF, the logs are retained on file by the dispatcher for a period of 90 days. At a public works, the DD Form 1970 is retained for 90 days and the Dispatcher’s Logs are retained for 36 months. TROUBLE  REPORTS  FILE.—  The  Trouble Reports Fide, commonly known as the  Hard-Card File, is  used  to  hold  the  NAVFAC  9-11240/13  (Hard  Card) and  the  NAVFAC  11260/4  (Operator’s  Daily  PM Report)  that  have  documented  repairs  above  the operator’s   area   of   responsibility   not   requiring immediate attention and are not a safety-related item. 6-20 To  avoid  disrupting  the  PM-to-interim  repair  ratio, you should store these cards with documented repairs in the Trouble Reports File until the piece of equipment is scheduled   for   a   preventive   maintenance   (PM) inspection.  The  PM-to-interim  repair  ratio  is  the number  of  scheduled  preventive  maintenance  actions compared  to  unscheduled  maintenance  actions  (interim repairs).  The  normal  goal  is  three  scheduled  PM inspections  to  each  interim  repairs.  The  standard interval  between  PM  service  inspections  for  NCF equipment  is  40  working  days;  therefore,  the  Trouble Reports  File  is  divided  into  40  PM  group  sections, covering each of these working days. When apiece of equipment is scheduled for PM, the cards in the Trouble Reports File for that USN are forwarded with the piece of equipment. YARD BOSS The yard boss and the dispatcher work as a team. The  yard  boss  has  a  key  part  in  the  Equipment Management  Program  by  enforcing  and  providing technical   guidance for   operator   pre-   and post-operational  checks  and  maintenance  procedures that  reduce  equipment  breakdown.  Additionally,  the yard boss manages the equipment yard and the vehicles parked in it, establishes and enforces traffic control through the yard, such as stop signs, speed limits, and one-way-traffic  flow,  and  is  in  charge  of  yard maintenance and the establishment of parking lines and areas, such as a ready line and awaiting-entry-into-shop line. The yard boss sees and hears the equipment that dispatchers cannot see while sitting behind their desks. The  yard  boss  is  also  responsible  for  cycling equipment  in  the  pool  that  is  not  regularly  used. Equipment must be maintained in a standby status and cycled on a weekly basis at its rated capacity for its intended  use.  Cycling  exercises  and  protects  equipment from   deterioration. Equipment  cycling  must  be documented in a cycle log maintained by the yard boss, documenting the date, USN number, duration of cycle, and  deficiencies. Tool Kit To   provide   tools   for   operator   maintenance procedures, the yard boss has a tool kit in the Battalion Table of Allowance for the support of the Yard Boss Program.  The  Kit  80111  provides  the  minimum  tools and  equipment  resources  necessary  to  support  operator maintenance.  For  control tools,  the  yard  boss  should and accountability of the have  operators  sign  a  log
