Note：Before and after the adjustment, check the accuracy by moving the main mirror up- and downwards a few times.
If the inspection/adjustment is made only for the front body, inspect again after the rear body is assembled.
・Angle adjustment of the main mirror to 45°
① Check for the left-right deviation
In case the deviation is out of standard, make an adjustment by loosening 3 screws (#1532) and moving the shaft plate
for the main mirror (#B239).
② Check for the up-down deviation
In case the deviation is out of standard, make an adjustment by turning the eccentric pin for the main mirror.
・Angle adjustment of the sub mirror to 49°
Check for the up-down deviation within the range of left and right 15' each.
In case the deviation is out of standard, make an adjustment by turning the eccentric pin for the sub-mirror.
