Canon NEW F-1 Service Manual page 3

The NEW F-1 is the base of a completely new Integrated Functional System. It is based on
the original F-1 but utilizing many advances in electronics, precision machining and precision
optics made since the original F-1 was developed ten years ago.
The following considerations should be kept in mind when repairing the New F-1:
1. To maintain complete interchangeability between the camera body and the system
accessories, repair personnel must understand the interfaces (mechanical
and electronic) between the body and accessories. They must also be familiar with
repair standards, checking, adjustment and tools maintenance procedures.
2 . Preventive maintenance (lubrication, adjustment and parts replacement) are
necessary to insure the reliability of the NEW F-1.
1. Many of the electrical contacts in the camera are molded into plastic insulators.
When making solder connections, the soldering time should be kept as short as
possible.
2. 3% silver solder should be used to solder the IC's.
3 . Many bearing balls are used in the winding mechanism. Be careful during assembly
and disassembly to insure that no balls get lost in surrounding mechanisms.
4. When the rewind crank is not installed, if the rewind shaft is pushed down past a
certain point it becomes impossible to open the back cover without removing
certain parts that normally need not be removed. This results in lost time.
5. Be sure that the elastic connectors used to connect the flexible and rigid circuit
boards are kept clean and free of contamination.
6. The water and moisture proofing complicates many repair procedures. Take care
that they are correctly performed
7. If the tungsten cable is kinked or frayed, repair is difficult and time-consuming. It is
much more cost efficient to be careful to not damage the cable than to repair or
replace it.
8 . The correct adjustment of the AV AE shutter speed indicator output resistor (RM
TV2) and the TV AE aperture determination resistor (RAE) are basic to maintaining
system interchangeability.
