5-2. Cautions in handling the mechanism
(1)Cut washers removed at the time of part replacement etc. should be
replaced with new ones without fail.
(2) Because no volume adjustment is available in this mechanism, cleaning or
part replacement should be performed if the setting is not satisfied.
(3) About oil
a) Be sure to use the specified oil. (If any oil other than the specified oil is
used, various troubles will occur.)
b) When lubricating the bearing, be sure to oil free from foreign particles
such as dust. (If oil in which foreign particles such as dust are mixed is
used, it will cause wear and seizure to the bearing.)
c) The term "One drop of oil" here means the amount of oil on the point of
a needle etc. shown in Fig.1.
(4) Repairing of circuits, final adjustment of running system, etc. should be
performed with the cassette controller assembly installed in the mechanism.
(5) When operating the mechanism singly, apply voltage to the loading motor
to drive it. The voltage between the terminals should be 3 to 4V DC. (Do
not apply external voltage to the loading motor with the mechanism
connected with the main circuit board. Doing so could cause a failure.)
(Turning the gears forcedly by hand may cause them to get damaged.)
When placing the mechanism singly, use an appropriate spacer so that the
capstan motor is not rubbed.
(6) When installing the cassette controller, push the portion indicated by "A" in
Fig.2. Do not push other portions.
(7) Take care not to deform the components of the mechanism.

6. ADJUSTING AND CHECKING OF MECHANISM
The items described here are relevant to the general on-site servicing (field service). This section does not cover adjustment and
replacement for which sophisticated equipment, jigs and techniques are required.
In order to maintain the initial characteristics of the mechanism, it is necessary to perform maintenance and inspection and also it is
essential not to damage the tape etc. In the case of an adjustment that requires a jig, be sure to use the specified jig.
<Caution>
(1) When adjusting and checking the mechanism, be sure to see that the power supply and the status are as indicated in
Caution on the title.
(2) Do not apply external voltage to the loading motor with the mechanism connected with the main circuit board. (Doing
so could cause a failure.)
(3) When running the tape, be sure to do so with the cassette controller assembly installed.
6-1. Checking of PB (REC) winding torque
AC adapter used, Cassette controller assembly installed
(1) Set the torque cassette with the cassette controller installed in the mechanism. In the SP record mode (or in the PB mode
if signals have been SP-recorded on the tape), check that the winding torque is within spec.
<Spec for PB (REC) winding torque>(If there is a torque ripple, read the center value.)
0.7+0.2/-0.05N·m, Ripple: 0.1mN·m or less
6-2. Checking of VS-REW winding torque
AC adapter used, Cassette controller assembly not installed (Mechanism only)
(1) Remove the cassette controller, turn ON the down SW while referring to 8-3, operate
in the test mode (T01) and select the VS-REW mode.
(2) Set the torque gauge in the S reel table, push the tip of the tension pole with your finger
in the direction shown by Arrow A to release the tension band, and check that the
winding torque is within spec. (Fig.1) (Do not apply the own weight of the torque
gauge or rotate it during measurement.)
<Spec for VS-REW winding torque>
(If there is a torque ripple, read the center value.)
1.5 ± 0.15N·m, Ripple: 0.15mN·m or less
(3) After checking the winding torque, remove the torque gauge and turn OFF the down
SW. The mechanism will automatically go into the standby mode.
Fig.1 How to release the tension
band when measuring the
VS-REW winding torque
6-3. Checking of height of reel table
3 to 4V DC, Cassette controller assembly not installed (Mechanism only)
(1) Remove the cassette controller. (Refer to 8-2.)
(2) Apply 3 to 4V DC to the loading motor while referring to 8-1 and select the
PB mode.
(3) Fit the holes of the master plane to the two guides (portions A and B) shown
in the Fig.2, taking great care not to allow master plane to strike the running
parts such as the drum and guide roller or the MIC contact.
(4) Using a pair of vernier calipers etc., measure the heights of the reel-supporting
faces of the S reel table and Tu reel table from the top face of the master plane
and check that the measured heights satisfy the set values. (Fig.3)
When measuring the height of the S reel table, push the tip of the tension
pole with your finger in the direction shown by Arrow A to release the tension
band. (Fig.1)
(5) If the measured height does not satisfy the set value, replace the reel table
and make checking again.
<Note> After replacement, select the L start mode (see 8-1) and check that the
reel table rotates smoothly.

6-4. Checking and adjusting of tension pole position during
REC (PB)
3 to 4V DC, Cassette controller assembly not installed (Mechanism only)
(1) Checking
Check that the tension pole is located in the prescribed position as shown in Fig.4
at the start of a 60-minute tape.
If the tension pole is not located in the prescribed position, take out the tape and
make adjustment according to the procedure shown below.
(2) Adjusting (See Fig.4.)
1. Select the PB mode without setting a tape.
2. Slightly loosen the screw 1 (to such an extent that the T band adjustment base
2 can be moved.)
3. If the tension pole is dislocated inward from the prescribed position, shift the

9. METHOD OF ADJUSTING THE ELECTRIC CIRCUIT
-Before making adjustment-
· It seems that, in most cases, this adjusting method is used when it becomes necessary to adjust the electric circuit as a result of
replacement of worn mechanism parts or the video head. When adjusting the electric circuit, check that the mechanism operates
properly (the mechanism is adjusted completely). If a failure occurs in the electric circuit, be sure to locate the fault using a
measuring instrument and then perform repairing, replacement and adjustment, as described in this adjusting method.
Avoid performing undue adjustments etc. without using proper measuring instruments.
· The electric circuit components in the circuit board unit of this product are densely-packed into packages. Most of them are surfacemounted for downsizing.
When replacing components in servicing the product, perform replacement work swiftly with a soldering iron.
In general, surface-mounted components are inferior in heat resistance to large-sized discrete components used in TV sets,
stationary decks, etc. Heating the electrode of a surface-mounted component with a soldering iron for a long time needlessly will
therefore lead to a failure. Take great care not to do so.
Take special care in this respect when replacing chip multilayer capacitors in particular.
We recommend you to use a ceramic soldering iron (Tip temperature: 250°C, Contact time: 5 seconds or less).
