Adjustment Checking the brake torque at the take-up side
If the reading of the cassette torque meter is less than
specified, move the tension spring hook toward A.
If the reading of the cassette torque meter is more than
specified, move the tension spring hook toward

Setting
Set a torque gauge to zero on the scale. Place it on the

Switch from the mode to the STOP mode.
Disconnect the AC power plug.

Checking
Rotate the torque gauge one revolution per 2 sec-
onds) in the clockwise direction and counterclockwise
direction of the supply brake so that the reel disk and
the indicator of the torque gauge rotate at an equal rate.
Check that the values are within the range of
direction =

and that the brake torque in the

Adjustment of the brake torque at the supply side and
the take-up side
If the supply or take-up brake torque is outside the range,
clean the supply or take-up reel disk brake lever pad, then
recheck the torque.
Note:
If the supply or take-up brake torque is still outside the
range, replace the main brake
When the main brake is replaced, per-f the height checking
and adjustment of reel disks (see page and the brake
torque checking.
