TM 5-3895-374-24-2Normally, the belt can be trained properly onto the tail pulley by manipulation of return idlers and with theassistance of self-aligning return rolls. Seldom is any adjustment of snub or tail pulley necessary, but the snubcan 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 appearwith load are usually due to off-center loading or to accumulation of material from the load on snub pulleys andreturn idlers.When equipment is known to be properly aligned, training action should be taken slowly that is, in small stepsbecause the belt requires some time to respond to corrective measures. It should begin at some point precedingthat where run off occurs and then gradually proceed forward, in the direction of belt travel, until the run offcondition has been corrected.page 3 - 1256
