Points to be remembered when making adjustment.
1.b. Release the shutter at "B". While pressing the shutter button, measure the pressure of the lst dia. lever
(02029) with use of the tension guage, at the spot where the lever presses the dia. pin of the lens.
The pressure should not exceed 320g, cm. In case the pressure is over and above this limit, the tension of the
mirror seat spring (02065) would not be strong enough to
the dia. lever joint spring (02119).
Therefore, when the pressure is over and above 320g, cm.
tweezers or pliers to keep the pressure within the tolerance of 280g, cm. - 320g, cm
Remember that if the pressure is below 280g, cm.
l.c. When (02065), (02018) and (02019) do not function satisfactorily, the usual cause may be traced to an
improper positioning of the hook of (02065).
When (02065) is replaced, be sure to check carefully if the hook of
Put your flnger on the tip of (02019) and try to tension (02065), and from the feelings of your finger as well
as from the sound of the ports, you can find out if (02065) and (02019) are functioning well.
2.c. In case where the old type 4mm-wide shock absorber (02079) is used, shorten its width by lmm. Where
required, cut off both ends of (02079) so that the entire shock absorber can be covered completely by the
mirror seat.
3.a. When the curtain actuator lever (02020) calked to (02018) does not attain its position when the mirror
actuator lever top assembly (02018) stops its movement due to the flip- up of the mirror, file away the slanted
port of the tip of (02110) that touches (02037).
However, care must be exercised not to file away the port to on excess because if filed away excessively, it
will result in incomplete flipping-up of the mirror.
