4-1-3. Maintenance Parts Replacement
It is recommended to replace the wear parts periodically if the FDD
is operated at a specially heavy duty condition or if it is operated
over five years.
Periodic replacement is not required for the parts
if the F D D .
is operated at a normal operation duty.
Table 403 shows all of the maintenance parts.
Replace the wear parts
according to the recommended replacement cycle.
Periodic replacement
is not required for parts without a recommended replacement cycle.
The replacement of the parts should be done according to each referred
item in Table 403.
Notes for Table 403:
(1) If two parts numbers are listed for one part, either of the two may be
used.
Fundamentally, parts without brackets are used at the shipment
though parts with brackets may be used since they are interchangeable
as spare parts.
(2) Since the parts number versions of the PCBA MFD control #B and the PCBA
front OPT vary depending on some factors such as signal interface
condition, be sure to confirm the version by checking the name plate
on the actual printed circuit board.
(3) The head carriage Ass'y are used always in pair with two guide shafts.
The head carriage Ass'y represented by listed parts number in Table 403
includes these guide shafts which parts number is different from that
of a head carriage Ass'y itself without these guide shafts.
(4) The listed parts numbers of the front bezel Ass *y and the front lever
Ass’y are those of standard color (black).
For designating other
color, use the corresponding parts number.
(5) The parts number version of the front bezel Ass'y and the front lever
