Replace the lid (Fig. 10). Remember to ensure the pressure release plug is pulled all the way out while closing, otherwise the air cannot escape. Squeeze the lid closed all the way with the hissing of expelled air. Screw home the pressure release plug (Fig. 11). There is no need to excessively tighten this plug. The seal is made by internal O-rings. The O-ring on the underside of the plug is just to keep out dirt.

After replacing the lid, make a final visual inspection of the main O-ring for contamination (Fig. 12).
