3. Play Torque Adjustment
Put the two pawls of the circular plate spring on proper
stepped position of the reel rest. The adjustable torque
range is 40 to 70 g-cm.
To make the torque high, put the pawls on a shallow
step. For lower torque, put them on a deeper step.
Torque can be adjusted by shifting position of the spring

When the motor (Reel motor MO02) is worn, FF and
REW modes may not function properly. In such a
case, renew the motor.
5. Pinch Roller Pressure
360g + 50g
Measure the pressure of the pinch roller using a gauge
as shown. For measurement, draw the pinch roller in
the arrow direction in which it is detached from the
capstan shaft and gradually return it toward the capstan.
Read the gauge at the time when the pinch roller starts
turning. The standard pressure is 360g + 50g.
