1-6. CLEANING AND LUBRICATION
1-6-1. CLEANING TAPE MECHANISM
Periodic cleaning is necessary to insure continued excellent
performance of the tape mechanism. To clean the following
parts, patch and solvent are available.
1. Capstan shaft.
2. All tape guide posts.
3. Clitch pulley.
4. Pinch roller.
5. Belt capstan.
6. Capstan motor pulley.
1-6-2. CLEANING OF ROTATING & STATIONARY
HEADS
To clean video heads, full erase head, audio/control (A/C)
head we recommend to use head cleaning kit and solvent.
Note : ‘When cleaning video heads, move. the cleaning
“slick in the direction of head rotation. _ Wiping i ina
» vertical direction n may damage the heads. :
Press a chamois cloth which has been dipped in cleaning
fluid lightly against the rotating cylinder assembly, then do
the cleaning by slowly rotaing upper cylinder ass'y by
hand.
Note’: Never try'to clean by using the motor to tum the
cylinder ass'y.
1-6-3, LUBRICATING TAPE MECHANISM
The tape transport mechanism is properly lubricated at the
factory.
In normal use cycles, and with average environmental
conditions, additional lubrication should not be required
during the first year of operation.
Depending on the frequency of use and environmental
conditions, periodic lubrication may be required.
When relubricating, remove old lubricant first, then
sparingly apply new lubricant.(Excessive lubricant may be
transferred to other assemblies causing malfunction).
Use grease on the following parts every 1,000 hours of
operations. (See exploded view for location)
1. Between base pole assembly (L, R) and main base.
_ 2. Gear escalator.
3. Gear Eft drive.
4. Gear loading L, R.
5. Slide main.
6, Lever tension control.
7, Lever shift.
Oil may be required for the following parts after 1,000
hours of operation.(See exploded view for location)
Main base
1. Arm tension molding.
2. Shaft reel disk L, R molding.
3. Shaft gear relay T, $1,S2, $3 molding.
4, Shaft clutch.
5. Shaft gear review.
Other parts which are not listed above do not require
lubrication, except when parts are replaced.
Use appropriate oil or grease as indicated on exploded
view.
