4. Insert retaining pin (29) half way into one hole of the mouthpiece
body (30). Capture both loop ends of the braided nylon cord (24)
using your thumb and index finger facing up, slide the hose (25)
back for clearance. Rotate your wrist pointing your thumb and index
finger down to form a "Larks Head Knot" on both loop ends. Capture
the knot onto the pin (29) of the mouthpiece body.
5. Press the pin (29) by hand until it engages equally into both
holes of the mouthpiece body (30). Apply a small amount of Gas-
gacinch to the diameter of the mouthpiece body hose barb. Allow
15 seconds for the adhesive to get tacky and slide the hose onto
the mouthpiece body with the mouthpiece facing to the right hand
side of the user as worn.
6. Secure each of the two clamps (23) to the spiral hose (25). The
outside clamp head faces in line with the mouthpiece. Clamp edge
distance to the end of the hose is 3.18mm (1/8 inch). The other
clamp faces the opposite direction over the pin (29).
