Troubleshooting the Malfunction: BAND SLIPS OFF
THE
WHEELS.
Two
conditions could cause the band to slip off the wheels:
(1) The upper wheel may not be aligned correctly, so that the band does
not track on the center of the wheel tire. Adjust the track of the band, if
needed, so that it tracks on the center of the wheel tire.
(2) The initial machine alignment may be wrong. When this is the case,
refer to TM 9-3419-228-10, page 2, for the procedure needed to solve the
problem.
