Adjusting the Wrenches

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. It’s

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.
