Note that the legs of the lever must be properly
aligned and in the same plane for the lever to work
correctly.
10) To bend the lever up, it’s best to remove the lever
and 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.
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.
11) To bend the lever down, place the disk end of the
KMDSI 1/4 ” wrench onto the flat area of the adjust
-
ment tube within the regulator, sliding the disk as far
as possible under the lever. With your finger, slightly
bend the lever down over the disk to the desired
height. Be careful not to bend the lever too far! Bend
it slightly then check it.
12) Replace the diaphragm and the cover. Test the
purge button. Continue until proper tolerances are
reached.
7.8.10 Regulator Steady Flows When
Pressured Up: Special Tools Used
Tools Required:
Small flat blade screw driver.
Small jewelers screw driver or metal scribe.
Needle nose pliers.
KMDSI regulator tool kit if available.
A few words about the demand regulator: The demand
regulator is very rugged and reliable. However, to
maintain optimum performance it should be checked
prior to each diving day in accordance with the brief
procedure "7.8.1 Demand Regulator Test for Correct
Adjustment, Fully Assembled" on page 76.
If after completing the demand regulator test as out
-
lined in Section 7.7.3 adjustment is necessary and
the special KMDSI tool kit is not available proceed
as follows.
1) Remove the regulator clamp, cover and diaphragm.
2) Adjust the regulator adjustment knob all the way
in, finger tight only.
3) Pressurize the regulator to between 135-150 p.s.i.g.
(8.5-10 bar).
4) Slowly back out on the adjustment knob until a
slight free flow is heard and then rotate the adjust
-
ment knob in (clockwise) 1/4 turn and depress the
lever momentarily. Repeat this procedure until the gas
flow stops. Usually at this point the regulator adjust
-
ment knob will be between 5 and 7 turns out.
Note:
If when backing the adjustment knob out from the
full “in” position, the regulator starts free flowing
at less than five turns, then this usually indicates
insufficient free play at the lever.
5) Upon completion of step 4. Check the free play at
the lever. The lever should have between 1/16-1/8 inch
(1.5-3.0 mm) play. If adjustment is necessary, adjust
using the KMDSI tools as explained in step 5, or the
alternative method described below.
6) KMDSI tools: Using the inlet valve holding rod, (L
shaped rod), insert the end of the rod into the balance
hole as shown. Lightly apply force by pushing on the
rod making it act as a lever to put friction against the
inlet valve shaft. At this point, the KMDSI wrench
can be used to rotate the lever nut. Rotate the nut “In”
(clockwise) to reduce lever play or “Out” (counter
clockwise) to increase lever play.
Only rotate the nut 1/8 turn at a time. Remove the
tools and depress the lever several times after adjust
-
ing to ensure the correct play is achieved. It may be
necessary to repeat this procedure several times, as
the method requires estimating the correct position of
Use the inlet valve holding tool with the KMDSI
wrench to adjust the regulator.
