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.
