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.
