• Remove the cassette housing control assembly.

• After short-circuiting TP801 provided at the center

(facing to the main PWB), plug in the power cord.

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

supply reel disk.

2. Switch from the FF mode to the STOP mode.
3. Disconnect the power cord.

• Checking

Turn the torque gauge at a rate of about one turn/2 sec
in the CW direction/CCW direction with respect to the
supply reel disk so that the reel disk and torque gauge
pointer rotate at equal speed, and make sure that the
value is within the setting (CW direction: 4.9 to 13.7mN·m
(50 to 140gf·cm); CCW direction: 2.9 to 9.8mN·m (30 to
100gf·cm).

• Adjustment
1. If the indication of torque cassette meter is lower than

the setting, shift the tension spring engagement to the
part A.

2. If the indication of torque cassette meter is higher than

the setting, shift the tension spring engagement to the
part B.

• Checking the brake torque at the take-up side

• Checking
1. Turn the torque gauge at a rate of about one turn/2 sec

in the CCW direction/CW direction so that the reel disk
and torque gauge pointer rotates at equal speed and
make sure that the value is within the setting (CCW
direction: 4.9 to 13.7mN·m (50 to 140gf·cm), CW direc-
tion: 3.9 to 10.8 mN·m (40 to 110gf·cm).

2. Adjustment of the brake torque at the supply side and the

take-up side

• Unless the supply side brake torque or take-up side

brake torque is within the setting, clean the felt surface
of reel disk (supply, take-up) brake lever, check again
the brake torque.

• If value cannot be set within the setting yet, replace the

main brake ass'y or main brake spring.
