Disassembly Note

Shutter Speed Selector
1.1.
To remove the shutter speed selector
(6), unsolder the black lead from SW4
and remove four screws [(6)-1 x 2 and
(6)-2 x 2].
Notes:
1. One of the (6)-1 screws is partially
hidden by flex (5) and hard to remove.
2. Be careful not to damage the main flex.
1.2 To remove the selector (6) completely,
unsolder the black and brown leads and
disengage the tungsten cable.
1.3 To temporarily remove (6) without
removing the tungsten cable:
1)
Set the shutter to the "B" position and
remove the screws. Carefully lift the
selector off.
2) Place the selector out of the way but
where the cable will remain taut and
not become kinked.
2. Mounting screw (9)-2 for the winding
base is under main switch (8).
3. The entire 2nd curtain brake assembly
(17) can be removed without
disassembling it by removing three
screws (15) and collar (16). Disengage
the brake lever from the
master gear and (17) can be removed.
Assembly and Adjustment Notes
1.
The shutter speed selector (6) TV double
brushes must be aligned both vertically
and radially, so they will both make
contact with the correct pad.
2. Clean the TV resistor board (2) and install
it so that break in the pattern is at the
upper right with the shutter at "A".
