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 Top wrench nut

(TN) 1" larger than the Middle

wrench nut (MN) and the Bottom

wrench nut (BN).

4. Rotate the Middle wrench nut (MN)

and the Bottom wrench nut (BN) to

the OD tool joint size. Visually align

the end face (F) of the wrench nut with

the scale (S) on the wrench.
