TM 10-3930-671-10 Operation How To Operate The Truck When  picking  up  a  load,  enter  the  load  carefully.    The forks must be fully under the load and spread as wide as possible to provide good stability and balance. If  the  forks  need  adjusting,  lift  the  fork  lock  lever.  Slide the  forks  on  the  fork  bar  of  the  lift  carriage  to  get  the correct  width  for  the  load.    Make  sure  the  fork  lock  pin fits into a locking notch on the fork carriage. Lower  the  lever  to  lock  the  forks  after  they  are  in  the correct position. E-80
