Push the crown (10) into

the larger threaded end

of the crown holder (8). Using

the seat installation tool (pn

127686), engage the crown and

turn clockwise until the tool dis-

engages from the crown. This is

the pre-set for the crown.

Fit a new MP seat (18) into the poppet (19). Replace the

entire valve insert assembly (18-24) into the case (5).

While holding the valve insert assembly (18-24) inside the

case (5), hold the lever (22) down and thread the crown

holder assembly (8-14) clockwise into the valve insert until the tab

on the ring locker (14) locks into the notch on the case.

Slide the tab on the ring locker (14) out of the notch on the

case (5) and rotate the crown holder (8) one more revolution

until the ring again locks into the notch. Confirm the crown holder

will not turn anymore.

CAUTION:

Failure to perform this last step and tighten the crown

holder all the way will cause a leak at first pressurization.

ADJUSTING LEVER HEIGHT

Attach the swivel end of the MP hose (28) to the second

stage by turning the swivel nut clockwise until it is secured

in place by the hose locker (12). Finally, attach the first stage to a

test bench or a fully charged 3000 psi (206 bar) cylinder. Slowly

pressurize the first stage.

Using the crown/lever adjustment tool (pn 125727), slide the

tool across the top of the case (5). The lever (22) must

touch the cutout on the tool without causing any air loss. This

lever setting is 2.5mm above the case edge. If the second stage

leaks the lever is set too high, use a ¼" nut driver to adjust the lock-

nut slightly CCW. If the lever is not touching the cutout in the tool it

is too low, turn the locknut CW to raise it. Once the lever height has

been confirmed, turn off the air supply and purge the regulator and

remove the MP hose (28) from the second stage.

Insert the venturi knob (17) into the opening on the right side

of the case (5) with the locking tab facing upward.

Insert the venturi (4) into the cutout in the venturi knob (17).

You should hear it "click" as the venturi locks into place.
