● 1 step of the set value corresponds to about 0.127 mm shift.
● Calculate the set value from the formula below.
B/0.127 (mm) = Lead edge void adjustment value <B: Lead edge
void (mm)>
B/0.127 (mm) = Lead edge void adjustment value <B: Lead edge
void (mm)>
Example: When setting the lead edge void to 2.5 mm:
2.5 /0.127 = about 20
Note: If the set value is not obtained from the above formula, per-
form the fine adjustment.
