This  section  provides  a  general  explanation  of  all maintenance and repair functions authorized at the various  maintenance  levels, The Maintenance Allocation Chart (MAC) in Section II designates overall authority and responsibility for the  performance  of  maintenance  functions  on  the identified end item or component. The application of the maintenance functions to the end item or compo- nent will be consistent with the capacities and capa- bilities of the designated maintenance Ievels. Section Ill lists the tools and test equipment (both special  tools  and  common  tool  sets)  required  for each maintenance function as referenced from Sec- tion Ii. Section IV contains supplemental instructions and explanatory notes for a particular maintenance func- tion. B-2.   MAINTENANCE   FUNCTIONS. Maintenance functions will be limited to and defined as follows: (1) (2) Inspect. To determine the serviceability of an item  by  comparing  its  physical,  mechanical, and/or   electrical   characteristics   with   estab- lished  standards  through  examination  (e.g.,  by sight, sound, or feel). Test. To verify serviceability by measuring the mechanical,  pneumatic,  hydraulic,  or  electrical characteristics of an item and comparing those characteristics with prescribed standards. (3) (4) (5) (6) (7) (8) Service.  Operations  required  periodically  to keep an item in proper operating condition, i.e., to  clean  (includes  decontaminate,  when  re- quired), to preserve, to drain, to paint, or to re- plenish   fuel,   lubricants,   chemical   fluids,   or gases. Adjust.  To  maintain  or  regulate,  within  pre- scribed limits, by bringing into proper or exact position, or by setting the operating character- istics to specified parameters, Aline. To adjust Specified variable elements of an item to bring about optimum or desired per- formance. Calibrate. To determine and cause corrections to be made or to be adjusted on instruments or test,  measuring,  and  diagnostic  equipments used  in  precision  measurement.  Consists  of comparisons of two instruments, one of which is a certified standard of known accuracy, to detect   and   adjust   any   discrepancy   in   the accuracy of the instrument being compared. Remove/Install.    To  remove  and  install  the same item when required to perform service or other maintenance functions. Install maybe the act of emplacing, seating, or fixing into position a spare, repair part, or module (component or assembly) in a manner to allow the proper func- tioning of an equipment or system. Replace. To remove an unserviceable item and install  a  serviceable  counterpart  in  its  place, “Replace”  is  authorized  by  the  MAC  and  is shown as the third position of the SMR code. B-1
