TM 5-3895-373-10 2.1.2 Switch    Panel.    The    switch  panel  provides  the following control features to the operator. 1. SCREED LIFT switch In  the  up,  LIFT  position,  the  screed  moves  up. In the down, FLOAT position, the screed moves down.  The center, HOLD position, is the screed hold position. 2. HORN switch Operates  the  paving  machine  horn.    Power  to the  paving  machine  is  not  required  to  operate the horn. 3. EMERGENCY STOP switch When pushed in, this switch cuts off all power to the paving machine, except to the horn and work lights, and stops the engine.  After the switch  is pushed   in,   it   must   be   pulled   out   before   the engine   can   be   restarted   and   paving   machine functions operated. 4. FLOW GATE switches Control   up   and   down   movement   of   the   flow gates,   which   control   the   amount   of   material reaching the augers.  In the up, OPEN position, the  flow  gates  open,  and  in  the  down,  CLOSE position,  the  flow  gates  close.      In   the   center, OFF position, the flow gates remain in position. 5. AUGER/CONVEYOR switches Select    between    center    OFF    position,    down "MAN",    and    up    "AUTO"    for    control    of    the auger/conveyor  systems.    In    the    up,    "AUTO" position,        the    auger/conveyor    systems    are automatically   controlled   by   the   position   of   the feed  limit  switch.    In  the  down,  "MAN"  position, auger/conveyor system operates regardless of the position of the feed limit switch. In  either  position,  the  feeder  control  switch  on the   screed   control   panel   must   be   in   the   ON position. 6. HOPPER WING switches In   the   up,   RAISE   position,   the   hopper   wings close.  In the down, LOWER position, the hopper wings open. CAUTION Use  extreme  caution  when  retracting extension    screed    when    auger    and fender  extensions  or  bolt-on  screed extensions  are  installed.    Damage  to extension screed can occur. 7. EXTENSION SCREED CONTROL switches Two switches control the extension and retraction of the extension screeds.  Moving  the left   switch   to   the   left   and   right   extends   and retracts  the  left  extension  screed,  respectively. Moving   the   right   switch   to   the   right   and   left extends and retracts the  right  extension  screed, respectively. 8. SCREED VIBRATOR switch Select    between    center    OFF    position,    down "MAN"   position,   and   up   "AUTO"   position,   for control    of    the    screed    vibrators.        When    in "AUTO", the screed vibrators operate only when the   control   handles   are   stroked   in   forward   or reverse directions and the travel switch is in the up, forward/reverse "F/R" position.  In the down, "MAN"      position,   the   screed   vibrators   operate continually. 9. This location is for the truck hitch control switch, which is not installed on the paving machine. 2.1.3 Auqer/Conveyor Speed Control Valves. The left speed  control  valve  regulates  the  speed of    the    left  auger/conveyor  system  and  the  right speed control  valve  regulates  the  speed  of  the  right auger/conveyor  system.    Turning  the  speed  control valve  counterclockwise  will  increase  speed  of  each auger/conveyor   system.      Turn   the   speed   control valve  clockwise  to  decrease  system  speed  and counterclockwise to increase system speed. 2-4
