• Preparation of service jig

(open/close of tray, up/down operation of traverse unit by

described on the items for disassembly procedures.)
- For preparation of gear (for servicing), perform the
procedures as follows.
- In case of re-servicing the same set, the "gear for
servicing" may be took off because it had been used. So,
the "gear for servicing" must be stored.
Step 1: Cut the gear out from the top cover.
Note: The bigger gear is for loading hole and the smaller gear
is for traverse hole.
Step 2: Insert the gear into the hexagonal wrench.
