Note:
Whenever replacing the reel disk, perform the height check-
ing and adjustment.

Notes:
1. Hold the torque gauge by hand so that it is not moved.
2. Do not keep the reel disk in lock state. Do not allow long-

time measurement.

• Setting
1. Set a torque gauge to zero on the scale. Place it on the

supply reel disk.

2. Press the rewind button.
3. To calculate the remaining capacity, slowly rotate the

take-up reel disk, and then shift it into the rewind mode.

• Checking
1. Turn the torque gauge slowly (one rotation every 2 to 3

seconds) by hand in the CCW direction.

2. Make sure that the indication of torque gauge is not less

than 30mN·m (306gf·cm).

• Setting
1. Set a torque gauge to zero on the scale. Place it on the

take-up reel disk.

2. Press the FF button.
3. To calculate the remaining capacity of the play back

mode, slowly rotate the supply reel disk, and then shift
it into the forward mode.

• Checking
1. Turn the torque gauge slowly (one rotation every 2 to 3

seconds) by hand in the CW direction.

2. Make sure that the indication of torque gauge is not less

than 30mN·m (306gf·cm).

• Adjustment
1. If the rewind winding-up torque is less than the specified

value, clean the capstan D.D. pulley, reel belt, and
limiter pulley with cleaning liquid, rewind again, and
check the winding-up torque.

2. If the winding-up torque is still out of range, replace the

drive belt.

• Setting
Press the playback button and rewind button to set the
video search rewinding mode.

• Checking
Place the torque gauge on the supply reel disk, and turn it
counterclockwise very slowly (one rotation every 1 to 2
seconds) and check that the torque is within the set value

• Checking
1. Make sure that value is within the setting 6.9     mN·m

(70    gf·cm).

2. The winding-up torque fluctuates due to variation of

rotation torque of limiter pulley ass'y. Read the center
value of fluctuation as setting.

3. Set the LP record mode (x2) and make sure that the

winding-up torque is within setting.

• Adjustment
If the playback winding-up torque is not within the setting,
replace the limiter pulley assembly.
Note:
When the torque cassette is set, put a weight (500g) to
prevent rise.
When the cassette torque meter is taken out.
Turn off the power switch.

Note:
Surely put the torque gauge on the reel disk to measure. If
the torque gauge is raised, accurate measurement is
impossible.

• Adjustment
If the rewinding playback winding-up torque is not within the
setting, replace the limiter pulley assembly.

Note:
The winding-up torque fluctuates due to variation of rota-
tion torque of supply reel disk. Read the center value of
fluctuation as setting.

• Checking
Press the play button to set the playback mode.
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 pull-

ing force when the pinch roller contacts the capstan
shaft.

4. Make sure that the measured value is within setting

change to 9.8 ± 2N (1.0 ± 0.2kgf).

• Checking
1. Set a cassette tape, push the REC button to place the

unit in the SP record mode. Now check the tension pole
position.

2. Visually check to see if the position of the tension pole is

within the 0         mm from the left side line.

Insert the tension pole adjustment driver to main chassis
hole, and rotate counterclockwise.
