Action
Remove one of the two modified fly wheels (P/N: M0771294), and secure one original
fly wheel and one modified fly wheel with TAPPING SCREW:4X12.
Repeat the procedure for all stations.
Note: The originally installed fly wheel should be visible when viewed from the non-
operator side of the unit, because the modified fly wheel is installed between the
original fly wheel and the mainframe.
If the results are accepted by the customer, the procedure is complete.
If the results are not accepted by the customer, remove the modified fly wheel so that only
the original fly wheel is installed for each station.
