16. Measure the distance between the two lines (B).
For a new chain:
•
If the difference (B) is 1
–
4 mm (0.04
–
0.16 in.), no more
adjustment is required.
•
If the difference (B) is greater than 4 mm (0.16 in.),
repeat Steps

For a used chain:
•
If the difference (B) is 3
–
8 mm (0.12
–
0.31 in.), no more
adjustment is required.
•
If the difference (B) is greater than 8 mm (0.31 in.),
