7.8.10 Tuning the SuperFlow
1) Remove the clamp, cover and diaphragm.
2) Screw the adjustment knob (clockwise) all the way
in, towards the regulator body.
3) Pressurize the regulator to between 120-150 p.s.i.g.
of supply pressure.
4) Screw the adjustment knob out (counterclockwise)
until the regulator starts to free flow, then screw the
adjustment knob in (clockwise) until the free-flow just
stops. Depress the lever several times to ensure the
free-flow has stopped.
If the free flow does not stop, the adjustment nut is too
tight. If the roller lever is sloppy (loose) the adjustment
nut is too loose.
5) Insert the inlet valve holding tool into the balance
hole on the inlet tube. Push forward on the tool to
stop the inlet valve stem from turning. Adjust the nut
until there until the freeflow just stops and there is
1/16 inch (1.5 mm) to 1/8 inch (3.0 mm) of free play
at the end of the lever.
6) Remove the inlet valve holder tool.
7) Put the diaphragm and cover in place, depressing
the cover tightly to simulate a properly tightened
clamp.
Insert the inlet valve holding tool into the balance hole on
the inlet tube.
8) Depress the purge button in the center of the cover.
9) There must be 1/16 inch (1.5 mm) to 1/8 inch (3.0
mm) of free travel before the purge button actuates,
resulting in a slight flow of gas. If a slight flow of gas
develops with the purge button depressed less than

Push down on the regulator cover to simulate a tightened
clamp.
1/16 inch (1.5 mm) the lever will require bending
down.
If the purge button travels further than a 1/8" (3.0
mm) before gas flow starts, the lever will require
bending upward.
NOTE: Before bending the lever, double-check
the adjustments. It is rare that the lever requires
bending. Usually levers only require bending be-
cause of they were improperly serviced previously,
or because of damage during disassembly.
10) To bend the lever up, you'll need to remove the
lever and carefully place it in a vice. Grip the lever
from the side with a pair of long nosed pliers and
bend the roller end up with your finger. Bend it only
a small amount at a time.
NOTE: Be very careful to not place undue stress
on the lower arms of the lever as this will disfigure
the lower blades and cause spongy operation.
