Step 3. Install the gasket by pushing it over the pipe until the center stop of the gasket is in contact with the end of the pipe.
Slide the other pipe end into the gasket ensur- ing it has also made contact with the center leg of the gasket. Both ends should be aligned ver- tically and horizontally.
The gasket should now appear evenly spaced between the two grooves and the outside of the gasket should be parallel with the pipe.
Note: The gasket should not protrude into the grooves on either pipe segment.
Step 4. “Swing” the coupling housing over the gasket. Verify that the housings are over the gasket and that the housing keys are fully engaged into the grooves.
Step 5. Slide the Coupling Bolt and nut into the housing and tighten the nut until finger tight. Verify that the bolt head is fully recessed in the housing and the nut is recessed into the counter-bore around the slot.
Step 6. Tighten the nut on the Coupling Bolt until properly tightened. There is no need to tighten the nut on the Pivot Bolt.
Visually inspect the coupling to assure that the housing keys are engaged into the grooves.
NOTICE
Figure 740 and Figure 640 Pivot-Bolt Rigid Cou- plings have an intended gap of up to 1/16 of an inch on the Coupling Bolt side to allow for posi- tive rigid gripping onto the pipe. The patented tongue-and-groove design provides protection to the back of the gasket during installation.
When setting the torque on power impact wrenches, always refer to the manufactur- er's recommended bolt torque specifications. Failure to use the manufacturer's settings and abide by manufacturer instructions may result in loss of warranty protection, invalidate listing certifications and/or cause personal injury or property damage.
