CHECKING AND ADJUSTMENT OF TAKE-UP
TORQUE IN FAST FORWARD MODE
l Remove the cassette housing control assembly.
l Setting
Torque gauge
Set the scale to “0”
+
/
Setting
Take-up reel disk
Figure l-27.
l Checking
Turn the torque gauge slowly
(one rotation every 2 to 3
seconds) by hand in the
take-up direction
700gcm or more
The gauge is held at
Id
its maximum value.
(Red mark)
Take-up direction
Figure l-28.
l Adjustment
1. If the take-up torque is outside the range, clean
the capstan D.D. motor pulley, reel belt and reel
pulley with cleaning liquid, then recheck the
torque.
2. If the take-up torque is still out of range, replace
the reel belt.
Notes:
1. Hold down the torque gauge so that it may not
fly off.
2. When checking the take-up torque, do not keep
the reel disk locked for a longer time.
