9. MECHANICAL SECTION ASSEMBLY AND PARTS REPLACEMENT
(DISASSEMBLY AND REASSEMBLY)
Mechanical section disassembly and reassembly are explained in this section.
For removal of the cabinet, etc., refer to 4. DISASSEMBLY OF THE SET.
<Precautions>
1. Always replace cut washers that have been removed, for example in parts replacement, with new ones.
2. When reassembling, be careful not to allow screws, washers or foreign matter to enter. They can cause mechanical misoperation.
3. Use the cleaning liquid, oil, grease and screw lock that are specified below. Use of any other kind can cause mechanical
misoperation.
Oil: Cosmo Petroleum : Cosmo Hydro HV22/HVlOO Screw lock: Three Bond :14OlB
Grease: Dow Corning : Moly Coat YM-103
Cleaning liquid: Industrial-use ethyl alcohol
4. Turn the mechanical section over, do not place it on, for example, a desk. Deformation and scratching of mechanical parts can
cause trouble.
9-1. On the mechanical modes
To operate the mechanism, apply DC3-4V to the loading motor.
At this time, disconnect the loading motor FPC from the connector.
[I) EJECT mode
The mechanism position to take out the cassette where the
EJECT lever is extremely shifted in the A direction. (It is impos
sible to lock the cassette controller assembly in this mode.)

3) LOADING START mode
This is the mode where the tape is wound around the winding
reel when a cassette with visible wind start leader tape is
loaded. (The brake shifter moves to the left, the S main brake
is separated from the S reel base and the Tu main brake is
separated from the Tu reel base.)

(2) STANDBY mode
The mechanism position to set the cassette where the slide
chassis is at the farthest position from the drum and the
EJECT lever is in clockwise rotated position (position where
the cassette controller assembly can be locked).

:4) REWINDING (VSR) mode
The mechanism position to rewind the tape (fast rewinding
playback). The S and T pole base is pressed, the pinch roller
is pressed to the capstan axis, the brake shifter VSR brake
section engages with the Tu reel base gear.
