EXPLODED VIEWS
NOTE:
-XX, -X mean standardized parts, so they may
have some differences 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
parts list.
