2-10-2, ALIGNMENT CONDITIONS
Adjust each head to satisfy each of the following conditions:
Example of
TILT
The head surface should be parallel to the tape guide
f
pin surface.
} |
AZIMUTH
The gap of the head core should be perpendicular
to the tape path.
HEIGHT
The upper edge of the upper core of the head should
be level with the upper edge of the tape.
TANGENCY
The dotted line should be perpendicular to the sur-
| face of the tape.

ALIGNMENT
PROCEDURE
1. By visual observation, align the erase, record, and playback heads
so that the proper tilt is obtained for each.
2. Coarse-adjust the azimuth of the erase, record, and playback
heads by observing each without a tape threaded.
. Load a TEAC YTT-8013 test tape and play it.
4. The erase head core should protrude 0.1 mm above the tape
while in motion. If not, readjust the azimuth and recheck the
tilt and height. Adjust as necessary.
5. Fine-adjust the height of the record and playback heads until the
brass-colored spacers appear above the moving tape. (The brass-
colored spacers appear about as thin as a pencil line.) When ad-
justing, make sure all the screws are turned proportionately so
that the tilt and azimuth previously adjusted is not altered.
6. If required, make a coarse adjustment of any head requiring
tangency correction, while the tape is running.

FREQUENCY
AND
VOLTAGE
CONVERSION
General Export Models Only:
If it is necessary to change the frequency and line voltage settings,
follow the instructions below:
ALWAYS
DISCONNECT
THE POWER
LINE CORD
BEFORE
MAKING THESE ADJUSTMENTS.
1. Remove the metal housing covering the top and sides of the deck
by unscrewing the three screws from each side.
2. Locate the voltage selector on the right (as seen from the front).
The frequency selectors are jocated near each motoras illustrated.
Voltage Conversion:
3. Turn the slotted center post of the selector with a screwdriver or
coin as illustrated until the proper setting is obtained.
Frequency Conversion:
4. For each reel motor, loosen the screws on the respective fre-
quency selector bar and jumper the bar to the terminal corre-
sponding to the AC line frequency of your area, then retighten
the screws.
5. Replace the housing and retighten the screws.
* Decks in some areas have a wooden case which can be removed by
unscrewing the screws on the bottom (feet) and sides,

2-12 LUBRICATION
Oiling is needed after every 1,000 hours of operatiw or once a
year if the deck is used infrequently. TEAC spindle oil( from TEAC
TZ-255 oil kit), Mobil D.T.E. Oil Light, and similar ty>es of oil are
recommended. Lubrication is normally not necessary o<cept at the
points shown.
1. Place the deck in a horizontal position.
2. Apply a few drops of oil to the respective spindles siown, except
the capstan and the reel motors. Spread the oil evenly on the
spindle surfaces using a cotton cloth or similar appliaator.
. For the capstan and reel motors, apply a few drop to the indi-
cated positions but do not spread the oil.
. After oiling all points, operate the deck for 1 to 2 hrs until the
oil is thoroughly absorbed.
