• EXPLODED VIEWS
The components identified by
mark 0or dotted line with mark
0are critical for safety.
Replace only with part number
specified.
• 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 num-
ber in the exploded views are not supplied.
• Hardware (# mark) list and accessories and
packing materials are given in the last of the
electrical parts list.
NOTE:
• -XX and -X mean standardized parts, so they
may have some difference from the original
one.
