Adjust the travel speed of the 1st curtain to be faster than that of the 2nd curtain by 0.05 - 0.1 ms.
Adjust it as follows
(1) Place the speed dial (05044) on the speed selector disc (05058) and set the speed dial at 1/1000 sec.
(2) Measure the curtain travel speed.
(3) Ease the two set screws (Set T 1.4 x 2) and rotate the worm (05041) clockwise to increase the shutter
curtain travel speed; and counter-clockwise to slow it down. When (05041) is turned clockwise,
slightly turn it counter-clockwise afterward.
(4) Fasten the two set
screws
(set T 1.4 x 2).
(5) Re-check the curtain
travel speed.
c. ADJUSTMENT OF HIGH SPEED EXPOSURE TIMING (1/60 sec.—1/000 sec.)
(1) Measure the speed at 1; 1000 sec. (1 ms).
(2) Ease the adjust nut (05111)
with
the special tool 225 K-F 48-A.
Rotate the set screw (Set T 1.4 x 2.5) clockwise to increase the exposure timing; and counter-
clockwise to slow it down. Fasten (05111).
(3) Re-check the speed at 1/1000 sec.
At this stage, re-measure the curtain travel speed as explained in paragraph 5, b. If the travel speed is
not within the tolerance, re-adjust it.
(4) Check the speed at 1/125 sec. (8 ms).
(5) If the speed is not within tolerance, adjust it as per 2) above.
