1. Detach the pinch roller from the capstan shaft.

Do not separate excessively. Or the pinch lever and
pinch double action lever may disengage.

2. Engage the tension gauge adapter with the pinch roller

shaft, and pull in the arrow direction.

3. Gradually return the pinch roller, and measure the

pulling force when the pinch roller contacts the capstan
shaft.

4. Make sure that the measured value is within setting 8.8

N to 11.8 N (900 to 1,200gf).

4-12 CHECKING AND ADJUSTMENT OF

TENSION POLE POSITION

•

Remove the cassette housing control assembly.

•

After short-circuiting between TP803 and TP802
provided at operation PWB, plug in the power cord.

•

Setting

1. Turn off the power switch.
2. Open the cassette tape (T-120), and fix with tape.
3. Set the cassette tape in loading state.
4. Put the weight (500g) on the cassette tape.
5. Turn on the power switch.
6. Make the adjustment with the beginning of a T-120 tape.

4-10 CHECKING THE VIDEO SEARCH REWIND

BACK TENSION

• Remove the cassette housing control assembly.

• After short-circuiting between TP803 and TP802

provided at operation PWB, plug in the power cord.

• Checking
1. After pressing the play button, press the rewind button,

and set the video search rewind mode.

2. Place the torque gauge on the take-up reel disk, and turn

it counterclockwise very slowly (one rotation every 2 to
3 seconds) and check that the torque is within the set
value 3.4
