I'm attaching a pic to illustrate parts of the regulator. When you turn the M tank on, the demand valve will be charged and ready to use. The mask flow control has no effect on the demand valve. You will leave it on "0" unless you use the O2 mask rather than the demand valve. You will need an adjustable wrench of sufficient size to attach the regulator to the tank and the demand valve to the regulator. Ensure the tank valve is closed before swapping regulators.
