Ly Stator circuit When replacing any of these components, use only manufacturer's specified parts.
1636 CNIO4 * $309 (end detection switch) will be replaced by MN1400PE of which the end detec-
tion unit is built into MN1400PA (1C301) in the course of manufacture.
At the time of servicing, it is possible to replace MN1400PA with MN1400PE, but not
MN1400PE with MN1400PA. Incidentally, MN1400PE will be supplied as repair parts.
