5) Check the free play at the lever. The lever should
have between 1/16-1/8 inch (1.5-3.0 mm) play. If ad-
justment is necessary, adjust using the KMDSI tools.
6) KMDSI tools: Using the inlet valve holding rod,
(L shaped rod), insert the end of the rod into the bal-
ance hole. 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 the nut.
Note: if there is little (less than 1/16 inch /1.5 mm)
or no lever play, the regulator will free flow. If there
is too much free play, (more than 1/8 inch / 3.0 mm)
the regulator will not be capable of full demand flow
potential.
7) If the free flow did not stop after this procedure, re-
fer to regulator disassembly and cleaning procedures.
Alternate method: If a KMDSI tool kit is not avail-
able, a small jeweler's screwdriver or metal scribe
can be inserted in the slot on the end of the inlet
valve to keep it from rotating, and needle nose pliers
may be used to rotate the lever nut. Holding the slot
of the inlet valve from rotating, carefully rotate the
nut "In" (clockwise to remove lever play and "Out"
(counterclockwise) to increase lever play.
Only turn the adjustment nut 1/8 turn at a time. De-
press the lever momentarily after each adjustment
and observe the lever play. It may be necessary to
complete this procedure several times, as the proce-
dure requires estimating the proper position of the
nut. If the regulator free flow did not stop after this
procedure, refer to regulator disassembly and cleaning
sections of this manual.
8) When adjustment is complete, place the diaphragm
and cover in place, and press tightly down on the cover
to simulate the action of the clamp.
9) With the cover pressed tight against the diaphragm,
if the regulator starts to free flow, the lever may need
94
to be bent down slightly. If the regulator does not free
flow, slowly depress the purge button until a slight
free flow develops. The purge button should depress
no further than 1/8 inch (3.0 mm) before the regulator
develops a flow.
If the regulator does not develop a slight free flow
when the purge button is depressed in 1/8 inch (3.0
mm), then the lever will require slight upward bend-
ing.
Before bending the lever, double check the adjust-
ments. It is rare that the lever requires bending in a
regulator that has been in service. Usually levers only
require bending in new installations or because of
damage during disassembly.
10) Install the clamp and clamp screw. Tighten the
screw to the correct torque (see appendix for torque
specifications).
11) Again, press on the purge button in the cover. It
must have 1/16 inch (1.5 mm) minimum and 1/8 inch
(3.0 mm) maximum free travel before it contacts the
diaphragm. If there is more than 1/8 inch (3.0 mm)
travel, the lever must be bent upward, per this chapter.
If the button has only slight or no free travel, the lever
must be bent down.
12) If the purge button travel is correct, the adjustment
is complete.
