FORSEGL ALLE SKRUER I BANDLOPET ETTER JUSTERINGENI

Ved nett pa og apparatet i opptak eller avspilling skal en klaring pa
0, 5 - 2 mm sikre at pressvalsen er 1 inngrep. Kraften malt pa
pressvalsen skal vaere 1,3 - 1, 5 kp, og kan finjusteres ved a variere
klaringen.

Vinkel for stopp av pressvalsearm. Bestemmer pressvalsearmens
og dermed bandets posisjon i stopp og hurtigspoling. Bandet skal
ligge ca. 0,5 - 1,0 mm fra avspillingshodet.

Senitjustering (parallelljustering) av pressvalse.

Asimutjusering av pressvalse.

Svinghjulaksen (capstan) skal stéi vertikalt pa bandlopsplaten. Jus-
tering foretas ved a lpsne pa de tre skruene som holder svinghjul-
braketten og forskyve denne parallelt med bandlopsplaten.

Knappen pa thrustefjaeren (trykklageret pa bladfjaeren) skal kun be-
rore drivakselen uten press.

Justering av signalsperrebryter (muting switch) skal skje nétr band-
opptakeren star i PLAY (avspilling). Bryteren skal vaere fipen i
PLAY og i REC, og skal kortslutte eventuelle signaler i WIND og
REWIND.

Sidestilling av formagnetiseringshode.
(avsnitt 2. 2).

En klaring pa 0,6 - 1, 0 mm i PLAY sikrer at formagnetiserings-
hodet ligger an mot innspillingshodet med minst 100 g. Justeres
ved a boye fliken pa kryssfeltarmen.

(Dvrige bandlpps- og hodejusteringer skal utfpres som beskrevet
for 6000X serien.

Unntak: Fluttertrinsens asimut- og senitstilling justeres med de
3 skruene pa braketten. Juster aksialklaringen ved hjelp av
plastgjengestiften med spor, pa toppen av braketten.

NOTE I

BE CAREFUL TO SEAL ALL SCREWS IN THE TAPE PATH
AFTER THE ADJUSTMENT.

With the power switched on, and the machine in a record/playback
mode, a gap of O. 5 - 2 mm will ensure the pinch roller to be in
operation. The force excerted by the pinch roller shall be

1. 3 - 1. 5 kp, and can be adjusted by altering the gap.

Angular bracket serving as stop for the pinch roller arm. Ensures
correct position for tape and pinch roller arm in STOP, WIND and
REWIND modes. The tape shall be 0.5 - 1 mm from the playback
head.

Zenith (tilt) adjustment of the pinch roller.

Azimuth adjustment of the pinch roller.

The capstan shall be positioned vertically to the tape path plate.

If the capstan is out of position, loosen the three screws holding
the fly-wheel bracket and adjust by moving this bracket parallel

to the tape path plate.

The capstan end-thrust bearing on the leafspring shall just touch

li htl .

Tlgie muting switch shall be adjusted with the recorder in PLAY
mode. The switch shall be open in PLAY and RECORD, and Short
(closed) in WIND and REWIND modes.

Horizontal adjustment of the bias head. See electrical adjustments
(paragraph 2. 2).

PLAY position. Adjust gap to O. 6 - 1 mm by bending tab on cross.
field arm to ensure that the bias head pressure against the play-
back head is at least 100 g.

The other adjustments of heads and tape path are accomplished in
the same way as for Series 6000X.

Exception: The azimuth and zenith position of the flutter
roller shall be adjusted with the 3 screws on the bracket.
Adjust axial movement of flutter roller with the plastic screw
used as thrust bearing at the top of the bracket.
