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
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.
Test the response of the purge button.
NOTE: Before bending the lever, double-check the
adjustments. It is rare that the lever requires bend-
ing. Usually levers only require bending because 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.
11) To bend the lever down, place the disk end of the
KMDSI ¼" 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.
B
CAUTION
The legs of the lever must be properly
aligned in the same plane. If one leg is
up and the other is down, the regula-
tor will not perform properly.
Use the disk end of the KMDSI wrench to bend the lever
down.
12) Replace the diaphragm and the cover. Test the
purge button. Continue until proper tolerances are
reached.
Note that the legs of the lever must be properly aligned and
in the same plane for the lever to work correctly.
