Place the wrench (1) on the nut (2) so that the force
used to turn it is applied to the stationary jaw side of
the wrench.

wrench fits the nut as tightly as possible.
CAUTION
If the wrench does not fit tightly, it will slip
and round the corner of the nut.
3
Swing the wrench clockwise to tighten the nut.
4 After the nut is tight, set it up (final tightening).

site direction to that in which the pipe is to be
rotated.
2 Slip the end of the strap through the shackle (3) and
draw it up tightly.
3
Pull the handle (4) to turn the pipe in the desired
direction until the desired tightness is obtained.
