* For the F side void amount, the target is 2mm.
[4 – 4.5 = -0.5 (mm)]
[4 – 4.5 = -0.5 (mm)]
(3) Calculate the adjustment value.
Subtract 5 from the shift amount of -0.5mm.
* For the shift amount of 0.1mm, the adjustment value is
varied by 1.
When the current value is 50:
[50 – 5 = 45]
(4) Enter the adjustment value for SUB-DSK.
