Teac A-6300 - 14. SERVICING AND MAINTENANCE; LUBRICATION GUIDELINES

1 4. SERVICING AND MAINTENANCE
1. Power supply:
Make sure that the power supply is stable at the rated voltage.
Fluctuations will result in uneven tape speed, and wow and flutter
in the recorded signal.
2. Cleaning the heads:
TEAC TZ-261A for Head cleaning, TZ-261B for Rubber cleaning must
be used.
3. Demagnetization of the head:
If the record or playback head becomes magnetized, noise will in¬
crease and fidelity will deteriorate. For this reason, it is ad¬
visable to use brass or other such non-magnetic tools when working
near the heads.
Similarly, the use of a tester or vacuum tube ohm-meter should be
avoided in checking the heads, as these instruments operate by
applying a DC current, and will thus induce magnetism. If the heads
have had any contact with DC currents or magnetic tools, demagnetize
the heads with a TEAC Model E-3 Head Demagnetizer.
4. Lubrication:
Under normal operating conditions, lubrication is required only once
each year. Before lubricating, clean the drive belt and drive pulleys.
Operate the deck for 30 minutes to 1 hour immediately prior to oiling.
After oiling, keep the deck in the upright position for 3 to 4 hours to
allow thorough absorption of the oil.
Approximately once each year or after 2000 hours of use, apply TEAC
TZ-255 Lubricating Oil to the following places only;
Pinch roller shaft bearings *••• 1 drop
Capstan shaft bearing.2 drops
* Remove the dust cap and washer for access to the felt
Capstan motor . 0.5 cc maximum to each oiling tube
NOTE: Apply 3 or 4 drops at a time through the oiling tubes.
The oil level can be seen to drop as the felt material
in the motor bearings absorb oil. When the level ceases
to drop, no more oil is needed. Do not attempt to force
oil into the motors nor exceed the maximum.
WARNING:Excessive oiling will scatter oil inside the deck. This
oil will cause drive belt slippage and other difficulties.
Check for slippage and clean all parts inside the deck
before operating after lubrication. Check for oil emission
after operation before returning deck to the customer.
