ADJUSTMENTS CASSETTE MECHANISM General Remarks • Before attempting to adjust the mechanism, wipe clean all tape-contacting surfaces (pinch roller, REC/PB head, erase head, and capstan), as well as the contact surfaces of the driving parts (motor pulley, flywheel, pulley, belt, and clutch assembly), with a piece of soft cloth moistened with denatured alcohol. Grease stains may cause trouble.
