Teac A-6010GSL - Brake Torque Measurement & Adjustment

FAST WIND BACK TENSION ADJUSTMENT
1. Load a full 1800 feet 7" reel of tape
on the right reel table and an empty
reel on left reel table and set the
TAPE switch to REGULAR position.
2. Depress the ( < ) and the FAST button
simultaneously.
3. At this time observe the right tension. .
Adjust R7 so that the arm moves approx. Lpig, 6-8 Fast Wind Check:
i" to the right and remains there.
4, Interchange the both reels, full reel on the right and empty reel on
the left reel.
5, Repeat above step 2, the full reel should start rotating quickly and
smoothly.
6. Repeat above procedure until the desired results are obtained.
BRAKE TORQUE MEASUREMENT & ADJUSTMENT
Brake adjustments are made with no power, applied to the unit.
1. Place an empty 10cm(4") hub reel and spring scale on left reel table.
2. Wind several turns of string counter clockwise around the hub.
3. Pull the spring scale away from the reel. Take a reading only when
the reel is in steady motion since the force required to overcome
static friction will produce a false, excessively high initial
reading.
The reading should be 300 grams (1500 g-cm +50 g-cm).
. If adjustment is required, adjust the adjustable nut attached to the
brake spring bolt for the proper brake torque.
6. To check and adjust the right reel brake repeat all steps as described
for left reel with the exception that all directions of rotation are
clockwise.
un
IMPORTANT: The difference in torque between the right and left brake
should be kept within 10 grams (50 g-cm).
