ASSEMBLY AND ADJUSTMENT
Note:
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. Especially, the parts lubricated with “L” lubricants need careful washing and drying.
However, the pipes containing curtain springs and governor assembly should never be immersed in
cleaning liquid for washing purposes.
Exposed plated and anodized parts should be throughly wiped either with a brush or with a clean piece of
cloth. When stains are found, lightly wipe off the stained parts with a clean piece of cloth soaked with
liquid composed of ether and alcohol at the ratio of 60% and 40%.
Painted parts need only be lightly dusted with a brush. Stains on the outer surface of black-finished
cameras should be wiped either with a silicon cloth (similar to the one usually used for wiping glasses and
is readily available on the market) or with the aforementioned liquid (60% ether and 40% alcohol). Wipe
them very lightly so as not to erase the engraved white letters.
For wiping optical elements, mixed liquid comprising 70% ether and 30% alcohol should be used. For this
purpose, a clean piece of cotton or hemp cloth, properly washed beforehand and entirely devoid of starch,
or a piece of soft paper is recommended.
For wiping plastic parts (such as Fresnel and ground glass), use mixed liquid composed of 50% ether and
50% alcohol, which gives satisfactory results.
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. Lubrication should be in strict accordance with the attached list of lube oils, as wrong use of oil
will invariably result in malfunctioning of various parts and may cause defects.
