wipe lightly with a cloth.
5-2. Precautions
(1) When replacing any part, always replace the cut washer that was
removed with a new one.
(2) This mechanism does not have control adjustment. If the control
cannot be set as required, clean and or replace parts.
(3)On the oil
a) Always use the specified oil. (Using another kind of oil can cause
various kinds of trouble.)
b) Always use clean oil, without any mixed-in dirt, to lubricate bearings.
(Using oil with dirt mixed in can cause the bearings to wear or to
stick.)
c) One drop of oil is the amount shown in the Fig. 1, on the point of a
pin.
(4)Perform circuit repair, tape running adjustment, etc. with the cassette
controller assembly attached to the mechanism.
(5)When operating the mechanism separately, apply voltage to the
loading motor. However, the terminal voltage must be DC3V~4V.
(When the mechanism is connected to the main PWB, do not apply
external voltage to the loading motor. It may cause a trouble.)
(Forcing the gears to turn by hand entails danger of breakage.)
If the mechanism is separated from the unit, the capstan motor may rub
and be damaged if spacing under the mechanism is inadequate.
(6)To install the cassette controller, push section A in the Fig. 2. Do not
push anything else.
(7)Do not deform any of the mechanical parts.

8-3. How to operate with the circuit board without the cassette controller assembly.
In this method, if the procedure is followed incorrectly there is danger of damaging the mechanism and the tape, so except in special
cases, such as when measuring the VSR torque, do not perform this procedure. Normally operate this unit with the cassette controller
assembly attached.
Be sure to follow each caution mentioned.
(1) Apply DC3 ~ 4V to the loading motor to enter the standby mode.
(2) Securely press the movable piece L of the down SW with
cellophane tape or similar to turn on SW. (Take care that the
movable piece turns only in the shown arrow direction.)
Note: To enter REC mode, press the pin of the recognition switch M.
(Unnecessary in other modes.)

9. ADJUSTING THE ELECTRICAL CIRCUITS
Before starting the electric circuit adjustment
• The adjustment methods described herein are used, in most cases, when the expendable mechanical parts, including
the video head, have been replaced, at which time the electrical circuits need to be readjusted. Before adjusting the
electrical circuits, make sure that the mechanism works properly (i.e., the mechanism is properly adjusted). Incase of
the occurrence of any problem to the electrical circuits, be sure to use the specified measuring instruments to locate
the area to which the problem is occurring, and then take the necessary action, including repair, replacement or
adjustment, exactly as instructed in the electrical adjustment methods that will follow.
Do not attempt to make adjustments without using the proper measuring instruments.
• This machine is configured so that the electrical circuits inside its PWB unit are composed, for the most part, of highdensity, small surface-mounted component parts for downsized machine body.
To perform repair service or parts replacement, do so using a soldering iron, but in as short a time as possible; this is
because surface-mounted component parts are generally so small in size and susceptible to heat, as compared with
the large discrete parts used in TV sets, desk-top video decks, etc., that attempting to heat their electrodes for a longer
time than is necessary with a soldering iron may result in their becoming defective.
This applies particularly when replacing the laminated chip capacitors.
For this purpose, ceramic soldering irons with a temperature regulator are recommended (iron tip temperature 250°C
and soldering time 5 seconds or shorter).
