1. The mounting screws of the disc motor also serve as adjustment screws. When reinstalling the
disc motor, first turn the screws A, B, and C as far as they go by usual force to secure them
(do not overtighten).
2. Back off the adjustment screws A and C two complete turns and secure them.
3. Back off the adjustment screw B one and a half turns and secure them.
This makes it nearly possible to play back disks and adjust the jitter.
Thereafter, adjust the adjustment screws C and A as indicated.
