1.
Slide the wrench end marked "Tighten" over and into
the threads of the fitting, not over the locknut!
2.
Engage the angled tab between the peaks of the locknut
and move the wrench downward to secure the locknut. (see pictures above)
3.
Tighten to desired torque, being careful not to over
tighten or break the fitting.
NOTE:
Do not use the torque handle extension with the straight wrench, as it was not designed or intended for this purpose!
Use the extension as shown above with the 90 degree wrench. The supplied torque handle slides
over the unused curved end of the 90deg wrench to provide the leverage required to tighten or loosen the locknut.
