Diving With The Regulator - Sherwood maximus Owner's Manual

4. Once pressurized do not attempt to reposition the regulator to achieve a different
hose orientation. Further, do not attempt to carry the assembly by the hoses or by
using the installed regulator as a handle for lifting the cylinder. This may damage
components and compromise your dive.
5. Sherwood regulators (except BRUT SRB9150) provide the user with a device to
control the venturi assist that is intended to decrease inhalation resistance at high flow
rates. The maximum assist or least resistance is present when the switch is rotated
clockwise toward the mouthpiece of the second stage. The venturi assist is reduced
(breathing resistance is increased) when the switch is rotated counterclockwise toward
the front of the second stage. When the venturi assist is reduced the regulator will be
more stable when the second stage is unattended. When the user is breathing the
switch should be in the least resistance position.
WARNING
You must be aware of and observe special measures for diving in cold water
at temperatures below 50°F (10°C) in order to minimize the risk of regulator
freezing. Training must include emergency measures for dealing with regulator
free flow. Failure to obtain the necessary training and mastery of the skills
needed before diving in cold water could lead to hazardous conditions with
possibility of serious personal injury or death.
