4, Release the guide roller. Fine-adjust the adjusting nut again until
there is no tape curling at the tape guide pin between the erase
head and the left (right) guide roller.
5. After adjusting the height of both left and right tension arms,
check that the tape running condition is good by repetition of
fast forward and rewind modes.
6. {f the tape running position is different when the guide roller
stops and when it turns, the condition when the guide roller is
rotating has priority.
2-9 TENSION ARM FORCE ADJUSTMENT
NOTE: The description below applies to both left and right sides.
1. Check the shut-off switch operates correctly with the deck in the
horizontal and vertical positions.
2. Adjustment can be done by changing the hooking position of the
tension arm spring against the spring hook.
2-10 DAMPER FUNCTION CHECK
NOTE: The explanation below applies to both left and right sides.
1. Check that the damper string begins to function after the tension
arm has moved 10 to 15 mm from the lowest position, while the
damping function is working, there is a feeling of resistance.
2. Check that the tension arm returns freely from the above posi-
tion to the lowest position.
