Action
Remove one of the two modified fly wheels
(P/N: M0771294), and fix the original fly
wheel and the 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 as the modified fly wheel is installed between the original fly
wheel and the mainframe.
If the results are accepted by the customer, complete the procedure.
If the results are unaccepted by the customer, remove the modified fly wheel so that only
the original fly wheel is installed for each station.
