Precautions On Reassembling

When reassembling, also refer to the
disassembling procedures.

Mounting the Traverse Mechanism

1. When mounting the pickup assembly, attach the feed slide

shaft assembly to the traverse chassis.

Apply E-JC-525 grease to the shaft.

2. Mount the middle gear and the feed slide shaft to the traverse

chassis and secure them with the screw (14) through the
shaft holder.

3. Before mounting the mechanism PCB assembly, move the

pickup to the outer edge position, then secure the PCB
assembly using the screw (15).
At this time, check that the rest switch is correctly placed.

4. To mount the rack arm, first move the pickup to the middle

position and secure it with the screws (16).
