NOTE :
• -XX, -X mean standardized parts, so they
may have some difference from the original
one.
• Items marked “ * ”are not stocked since they
are seldom required for routine service. Some
delay should be anticipated when ordering
these items.
• The mechanical parts with no reference
number in the exploded views are not
supplied.
• Hardware (# mark) list and accessories and
packing materials are given in the last of this
