ASSEMBLY AND ADJUSTMENT
Before assembling, disassembled parts need a careful washing and/or dusting with either a piece of cloth or a blower. General rules are summarized below:
- Parts equipped with rotating shafts and/or shaft bearings should be thoroughly washed with high quality gasoline or benzine.
- Exposed plated and anodized parts should be thoroughly wiped either with a brush or with a clean piece of cloth.
- Painted parts need only be lightly dusted with a brush.
- For wiping optical elements, mixed liquid comprising 70% ether and 30% alcohol should be used.
- For wiping plastic parts, use mixed liquid composed of 50% ether and 50% alcohol.
- Stained mirror surface should be wiped very lightly with a piece of cloth soaked with mixed liquid composed of alcohol and ether.
- Ammeters, CdS cells, variable resistors and semi-fixed resistors should never be washed.
It is of utmost importance to observe the right kind of lubricants, lubricating positions and lubricant quantity.
Troubleshooting and error codes
| DEFECTS: | CAUSES: | SERVICING: |
|---|---|---|
| Correct exposure cannot be obtained, Pictures taken are either extremely over-exposed or under-exposed. | 1. The voltage of the battery is getting low; perhaps not to zero, but is below 1.3V. 2. Faulty indication of the needle of the ammeter. |
1. Replace the battery. 2. Replace the ammeter. |
| Even when the warning signal (the index of the shutter speeds) turns to red, the needle of the meter does not rest properly. | The two terminal plates (10029) affixed to the variable resistor do not make contact with the contact piece (10032). | Set the ASA scale on the shutter speed dial at ASA 100 and the shutter speed at "B" and bend (10029) with tweezers so as to make it contact with (10032). |
