Adjust for Make Up
1. Measure the tool joint with OD
calipers.
2. Use the 1 1/4" wrench to adjust
the Pointer (P) on the Pipe stop
index (PI) to the OD tool joint
size. Its always better to adjust
the pointer 1/4" larger than the
measured diameter of the tool
joint.
3. For safety, adjust the Bottom
wrench nut (BN) 1" larger than
the Top wrench nut (TN) and
Middle wrench nut (MN).
4. Rotate the Top wrench nut
(TN) and the Middle wrench
nut (MN) to the OD tool joint
size. Visually align the end face
(F) of the wrench nut with the
scale (S) on the wrench.
