GENERAL REMARKS
e
Before
adjusting
the
mechanism
of
the
unit,
clean
the
tape
contacting surfaces with a soft cloth soaked in alcohol.
Trouble may occur because of oi! and grease stains.
The Belts must be kept clean while the adjustments are
performed.

Silicone
grease
(Example:
SHIN-ETSU
SILICONE
KS-64)
is
applied
to
the
Drive
Belt
and
the
Take-up
Belt
to
protect
them
from
abrasion.
If
necessary,
apply
a
proper
amount
of
silicone
grease
(Example:
SHIN-ETSU
SILICONE
KS-64)
to
each
groove
of
the
Flywheel
and
Friction
assemblies.
NOTE:
Silicone grease is not applied to the Replacement Parts.
@
Never
apply
grease
or
oil
to
the
ASO
Belt.
If
applied,
wipe
it
clean with benzine.

Do not excessively bend it.
ADJUSTMENTS
FLYWHEEL THRUST ADJUSTMENT
Check to see that the clearance between the Flywheel Thrust
and Flywheel is 0.09 — 0.17mm with the chassis upside down as
illustrated. If necessary, adjust the clearance by the following
procedure.

1. While moving the Capstan up and down, slowly turn the
Flywheel Thrust clockwise to obtain the clearance of "O”
between the Thrust and the Flywheel.
NOTE:
Do not turn the Flywheel Thrust forcibly.
2. Turn the Thrust counter-clockwise by 45° — 90° from the
position.
3. After the adjustment, secure the Flywheet Thrust with paint
or glue.
TAKE-UP TORQUE ADJUSTMENT
1. Insert the cassette-type torque meter into the unit and
measure the torque of the Take-up Reel Gear with the unit
in the playback mode. It should be 30 — 50g-cm.

If the torque value is more than 100g-cm, apply a proper
amount of silicone grease (Example: SHIN-ETSU SILICONE
KS-64) to the groove of the Friction Assembly. Then, make
the Motor rotate and apply the silicone grease to the
Take-up Belt.
If the torque value is less than 55g-cm, replace the Take-up
Belt with a new one.
MOTOR SWITCH ADJUSTMENT
1.
Set the unit in the Stop mode and check to see that the
clearance between the Motor Switch and the Brake is
0.1 — 1.5mm as illustrated, and that the Motor Switch is
turned on by pressing one of the Select Buttons (PLAY, FF,
or REW).

TAPE RUNNING CONDITION ADJUSTMENT
1.
Prepare the cassette tape (C-120} as the test tape for this
adjustment.
Insert the test tape into the cassette compartment and play
it back. Then, check to see that the tape is not curling along
the Tape Guide of the Erase Head while the test tape is
being played back.
\f necessary, tighten the adjusting screw and slowly loosen
the
