PRECAUTION
1. Clean the following parts with a denatured-alcohol-
moistened swab :
record/playback head pinch roller
erase head rubber belts
capstan idlers
2. Demagnetize the record/playback head with a head
demagnetizer. (Do not bring the head demagnetizer
close to the erase head.)
3. Do not use a magnetized screwdriver for the adjustments.
4. After the adjustments, apply suitable locking compound
to the parts adjusted.
