(Refer to Fig. 5-7.)
1)
Playback the tape and set the REV mode.

Confirm that tape slack does not occur in between the No.6

the TG7 nut 4 of the No.7 guide (TG7) 3 to remove the tape
slack.
3)
Playback the tape again and confirm that tape slack does not
occur between the capstan 2 and No.7 guide (TG7) 3. If the
tape slack occurs exceeding the specifications (specifications:
0.5 mm or less), rotate the TG7 nut 4 to make the tape slack
below the specifications (0.5 mm). When the tape slack between
the No.6 guide (TG6) 1 and capstan 2 is 0.3 mm or less in
the REV mode, it means that the adjustment is completed.
