<Adjustment Procedure>
c
Make measurements with a Yunitta's tension meter placed at the positions indicated by the
arrows in the figure below and check to make sure that the values are within the specification
value range.
(Note 1) When adjusting the Y-motor belt, measure the tension at several positions (at
least five positions) while rotating the pulley and check that the averaged value is
within the specification value range.
