• Carry out the following maintenance and periodic checks not only to fully display the functions and performance of the set, but also for
the equipment and tape. After replacing, service the set as follows, regardless of the length of use.
2-1. CLEANING OF ROTARY DRUM ASSEMBLY
1. Press a wiping cloth (J-2) moistened with cleaning fluid (J-1)
against the rotary drum assembly gently, and clean it while
rotating the rotary drum assembly slowly with your finger in
the counterclockwise direction.
Note:
Do not rotate the motor on power or rotate the rotary drum
assembly in the clockwise direction with your finger. The
head tip will also be damaged if the wiping cloth is moved

above instructions when cleaning the rotary drum assembly.
Note: When overhauling, refer to the checks above and replace
parts.
Note:

various problems may occur.
(Use SG-941 for all parts of the R mechanism.)
