4.1.4 Adjusting the Play Timing
It is normal that when the PLAY pushbutton is
depressed, the take-up reel table turns first, then
the pinch roller is rotated. The reel table and
pinch roller must not start turning at the same
time,
NOTE: Make certain that such a subsequent
operation is made irrespective of locking
state is depressed slowly without load-
ing the tape.
(1) Checking for adjustment
Check whether or not the clearance between the
pinch roller and capstan is 0.2 to 0.5 mm when
the take-up reel table starts turning with the
PLAY pushbutton depressed slowly.
(2) Adjustment
Bend the pinch roijler bracket at the point that
touches the head chassis stopper. In the line
drawing, bending left reduces the clearance be-
tween the capstan and pinch roller.
NOTE: Make certain that the pinch roller
bracket does not leave touching the
head chassis stopper in the play mode
of operation as a result of excessive
bending.

4.1.5 Adjusting the Play Torque
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.
@ Checking the take-up clutch for sliding
Make certain that the flywheel rotates freely
when the reel table is locked. The flywhee!
that revolves irregularly or stops is not accept-
able.
4.1.6 Adjusting the Fast Forward and Rewind
Torque
The fast forward and rewind idler has a torque
adjust plate spring (part A in the line drawing),
which has two pawls (part B) at its ends. Set the
pawls in proper one of the three steps. To make
the torque high, set the pawls in the shallowest
step. For lower torque, set in the deepest step.
