ADJUSTMENT
OF PINCH
ROLLER
at
. Set the unit to the PLAY mode.
2. Apply
a tension gauge to the pinch roller. Read
the gauge at the
precise moment when the pinch roller separates from the capstan.
3. If the gauge reading is within a range of more than 200 g, no adjust-
force of the spring coil. (See exploded view No. 23)

TORQUE
ADJUSTMENT
1. Set the unit to the PLAY, FAST FORWARD
or REWIND
mode.
2. Measure the each torque with a torque gauge. They
should be as
following;
PLAY
30 — 60 g/cm
FAST FORWARD
55 — 110 g/cm
REWIND
55 — 110 g/cm
3. If the each torque fails to reach the standard value. Clean the drive
belt, flywheel, métor pulley, take-up reel, idler and rewind roller
with a cotton swab soaked in alcohol.
AUTO
SHUT-OFF
ADJUSTMENT
1. Set the unit to the PLAY mode.
2. Apply a tension gauge to the sensor. Push the gauge and measure
the sensor pressure.
3. The sensor pressure should be 30 — 50g.
4. If a sensor pressure of more than 50 g, or less than 30 g, adjust the
spring coil (See exploded view No. 25).
