When the bin roller is replaced or reassembled, check the standard
dimensions and change and adjust the installing angle of the dummy
roller lower if necessary.
1) Adjustment procedure
Stand up the bin unit straight. Measure the distance between the
upper dummy roller (1) and the bin roller (2). If the distance is too
large, rotate the lower dummy roller (3) counterclockwise. If the
distance is too small, turn it clockwise. Turn and adjust so that the
distance is about 97.8mm.
