TM 5-3895-374-24-2 Normally,  the  belt  can  be  trained  properly  onto  the  tail  pulley  by  manipulation  of  return  idlers  and  with  the assistance of self-aligning return rolls.  Seldom  is  any  adjustment  of  snub  or  tail  pulley  necessary,  but  the  snub can be used in supplementary training. Training of the top run, with the belt empty, usually is no problem if the belt is readily troughable. It should not be necessary to use the head pulley for training purposes if it has been aligned properly. With the empty belt trained satisfactorily, good operation with load is usually ensured.  Disturbances that appear with load are usually due to off-center loading or to accumulation of material from the load  on  snub  pulleys  and return idlers. When  equipment  is  known  to  be  properly  aligned,  training  action  should  be  taken  slowly  that  is,  in  small  steps because the belt requires some time to respond to corrective measures.  It should begin at some point preceding that  where  run  off  occurs  and  then  gradually  proceed  forward,  in  the  direction  of  belt  travel,  until  the  run  off condition has been corrected. page 3 - 1256
