PERIODIC CHECK AND REPLACEMENT
In order to obtain the best performance from this unit and make full use of its capabilities, and to extend the life of the unit and tapes, it is recommended that the following periodic checks and maintenance be performed. * The following must be done after every repair regardless of how many hours the user has operated the machine.
2-1.
1)
CLEANING OF ROTATING HEAD DISK ASSEMBLY
2-2.
1)
CLEANING OF THE TAPE MOVEMENT SYSTEM
2)
Press a chamois cloth (Jig Ref. No. J-4) which has been dipped in cleaning fluid (Jig Ref. No. J-3) lightly against the rotating drum assembly, then do the cleaning by slowly rotating the rotating head disk by the hand. (Never try to clean by using the motor to turn it.) Never try to clean by moving the chamois cloth at a vertical angle to the head tip. There is a very great danger of damaging the head tip if this is done.
Clean the surfaces which the tape contacts during its movement (tape guide, drum assembly surface, capstan, pinch roller, etc.) with a chamois cloth that has been dipped in cleaning fluid.
