Loosely fasten a strap clamp (60) into the groove at the base

using diagonal pliers.
NOTE: The mouthpiece can be adjusted to several
different user preferred positions. (Reference the

be heard as the hose nut is tightened into place. Check the
hose nut is locked into place and cannot be loosened without
squeezing the locking slide ring (58).
