TM 10-3930-669-34 (c) To select the neutral position for the transmission, move the control lever to the center position. (2) The  high/low  range  selector  switch  is  located  on  the  right  side  of  instrument  panel.    The  electric  control  rocker switch controls a solenoid in the transmission.  This solenoid switches the transmission into high range, when energized. The  truck  should  normally  be  operated  in  high  range  only.    Changing  from  one  range  to  the  other  is  accomplished  by pushing the transmission range control button.  The high range light will light on the instrument panel when high range is selected. c. Drive  Axle.    The  forklift  is  equipped  with  a  Clark-Hurth  Model  172  drive  axle.    This  drive  axle  features  gear reduction at the wheel ends and is equipped with wet brake discs that serve as the service brakes. d. Inching System.  The inching system works with both the drivetrain and the brake system.  The inching system permits extremely slow movement for precise load positioning.  Light brake application at slow engine speeds activates the inching solenoid valve.  This reduces the hydraulic pressure actuating the hydraulic  clutch  pack  allowing  the  clutches  to slip and the machine to be inched. 1-7
