or unsoldering. Check leakage as described below.

This appliance is classified as a CLASS 1 LASER product. LEAKAGE TEST

The CLASS 1 LASER PRODUCT MARKING is located on The AC leakage from any exposed metal part to earth ground and
the bottom. from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indica-
tion is 0.75 V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-
amples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2 V AC range are suit-
able. (See Fig. A)

NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical

3-14. CARRIAGE

1 After taking out drawer from chassis, overturn the drawer and place on a jig, to prevent scratches on the drawer.
2 On the left hand side of the drawer, has a gear call the bevel gear.
Make sure after taking out drawer from the chassis, this gear is still attached to the drawer.
If not, please refer to the picture below and fix back the bevel gear.

3 Using the left hand thumb and place on the bevel gear and the other hand holding the drawer.
4 By turning the bevel gear anti clockwise direction, this gear turning will cause the upper pinion to turn.
The result, it will cause the upper carriage to move out in the direction as shown in the picture below.

5 When bevel gear is turned anti clockwise, the upper pinion will in also turn 5 times.
When the upper pinion turns, it will transport the upper carriage out from its original position.
When the upper carriage moves to it’s max position (upper pinion turns 5 times) the lower carriage will drop down next.
Carriage up/down is controlled by this part called star gear.
From here, the upper carriage can be taken out. Method as shown below in the picture.

6 Next to take out the lower carriage. The bevel gear is turned anti clockwise.
The lower pinion will turn 5 times. After turning the front star gear will turn slightly.
After finishing, next the upper pinion will turn 5 times.
While it turns, it will transport the lower carriage out to its max position.
From there, the carriage is taken out the same way as how the upper carriage is taken out.

Note: Carriage having two punches is cavity No. 3.

4 When placing the carriage into the drawer, make sure the carriage is fixed underneath the star gear
and the last teeth into the front teeth of the upper pinion.
After confirming position, the other side of the carriage will have to be pressed down (RHS)
underneath the other side of the star gear.

5 Turn the bevel gear in a clockwise direction and the carriage will move to the back of the drawer.
Pinion will turn 5 times.
6 After the carriage reaches to the back of the drawer, the front star gear will turn slightly,
after that, the lower pinion will turn 5 times. After that, the back star gear will turn slightly and lift the carriage up.
(Help is needed to push the carriage upwards by hand)

Note: The other piece of carriage must be place on the drawer,

same as the first process, before the upper pinion starts to turn.

7 Place the next piece of carriage with the same way as the first piece of carriage is done.
8 Turn the bevel gear in clockwise direction and the 2nd piece of carriage will move in.
Before the next carriage is placed onto the drwar, the first carriage must be pushed up by hand.
