TM 1-1510-218-10 2-88 2-71.  WINDSHIELD WIPERS. a.   Description. Two     electrically     operated windshield   wipers   are   provided   for   use   at   takeoff, cruise, and landing speed.   A rotary switch, placarded WINDSHIELD    WIPER,    located    on    the    overhead control panel, Figure 2-15, selects mode of windshield wiper   operation.    An  information  placard  above  the switch states:  DO  NOT  OPERATE  ON  DRY  GLASS.   Function  positions  on  the  switch,  as  read  clockwise, are: PARK / OFF / SLOW / FAST.  When the switch is held in the spring-loaded PARK setting, the blades will return to their normal inoperative position on the glass; then,   when   released,   the   switch   will   return   to   OFF position  terminating  windshield  wiper  operation.    The FAST    and    SLOW    switch    positions    are    separate operating   speed   settings   for   wiper   operation.      The windshield wiper circuit is protected by one 10-ampere circuit breaker, placarded  WSHLD WIPER, located on the overhead circuit breaker panel. CAUTION Do  not  operate  windshield  wipers  on  dry glass.  Such action can damage the linkage as well as scratch the windshield glass.  b.  Normal Operation. To start, turn WINDSHIELD   WIPER   switch   to   FAST    or    SLOW speed,  as  desired.     To  stop,  turn  the  switch  to  the PARK position and release.   The blades will return to their normal inoperative position and stop.   Turning the switch only to the OFF position will stop the windshield wipers  without  returning  them  to  the  normal  inactive position. 2-72.  CABIN FURNISHINGS. a.   Cabin Area Interior.   The cabin has seating arrangements for seven passengers.  Seating consists of   five   executive   chairs   and   one   two-place   couch attached   to   floor   mounted   rails.       Track   mounting accommodates    quick    seat    removal    and    spacing adjustment.  Five seats face forward.  On the right side of  the  aisle,  the  couch  faces  towards  the  aisle.   On a horizontal   leg   crossbar,   each   seat   is   placarded   as FWD FACING or  AFT FACING.   All chairs and each place  on  the  couch  are  equipped  with  lap-type  seat belts.       All    chairs    have    adjustable    headrests    and reclining  backs,  which  can  be  adjusted  by  a  lever  on the  side  for  individual  comfort.    Adjustable armrests, adjacent to the aisle, may be lowered to allow ease of entry.  All seat backs shall be in full upright position for takeoff and landing. b.  Aft  Cabin  Area  Interior    C  .    The  aft  cabin area has two parts: a toilet area (fwd part) opposite to the aircraft entry door, and a storage area that extends from  the  aft  side  of  the  doorway  to  the  back  of  the pressurized    compartment.        A    partition    wall,    with lockable  internal  sliding  doors  at  the  aisle,  separates the  passenger  area  from  the  toilet  area.    A  mirror  is mounted     on     the     right     forward     partition     and     a removable  low  profile  electric  toilet  faces  the  aisle.  A garment hang cable extends between the forward and back partitions above the toilet.  A seat belt is provided and allows approved seating of one passenger in the toilet area.  This area also has lighting, ventilation air, and   oxygen   provisions.      The   toilet  and  aft  storage areas are separated by a partial partition from the right fuselage   wall   to   the   aisle.      A   garment   hang   cable extends  from  this  partition  to  the  aft  bulkhead  of  the pressurized compartment.
