Removal of Optical Pickup Head (Fig.10 and Fig.11)

1. Remove 3 screws (F1).

Caution

Use care so as not to cause any damage to the gear.

(The damaged gear will cause abnormal noise to occur

while searching.)

The leaf spring (A) attached to the P.U. will be reused

when replacing the pickup. It is not supplied with the

optical pickup.

3. Using tweezers or the like, pull the PU shaft from the

base a little. Pull only enough to allow the pickup to

come off. If it is pulled off completely, the oil on the

shaft will be scraped off.

Be sure to keep oil on the shaft!
