18. Hold the orifice housing in one hand. Temporarily install the adjuster knob and use it to

turn the orifice clockwise until it comes out of the orifice housing. Remove and discard the

o-rings on the orifice & , and the orifice housing & .

19. Before removing the exhaust valve from the case, bend it over as far as it will go from the

top, bottom, left and right sides. If it fails to snap back quickly, and does not lie perfectly flat

against the case, the valve should be replaced. If it does snap back satisfactorily, remove it and

inspect the sealing edges. If they appear smooth, and the locking tab on the nipple is good, the

valve can be reused.

20. Rinse all plastic and silicone parts in clean fresh water, and then blow the parts dry with

compressed air to remove any sand and dust particles.

21.

If necessary, clean all metal parts of the second stage in an ultrasonic cleaner or cleaning

solution. Remove the o-rings before cleaning any metal parts; most cleaning solutions are

damaging to the o-ring material. See

Section 6.3 for recommendations on cleaning solutions.

22. Inspect the case for any cracks. Look particularly closely at the area where the orifice

housing and the lever support clamp down. Replace the case if any cracks are found.

23. Inspect the sealing surface on the orifice (where the poppet insert seals) for any nicks,

scratches, or corrosion. Corrosion or minor scratches can be polished out using a fine-grit

rubberized polishing stick or a clean new pencil eraser. Do not apply heavy pressure when

rotating the polishing stick. Stop polishing immediately after the corrosion or scratch

disappears. An orifice will not be accepted for warranty replacement simply because it is dirty

or corroded. The technician must clean the orifice sealing surface at every service interval.

24. Blow all dust and debris out of the orifice housing with clean compressed air.

5.3 ASSEMBLY OF SECOND STAGE

1. Install the exhaust valve into the case by inserting the nipples into the small holes from the

outside of the case. Reach inside the case and pull the nipple firmly with the fingers until you

hear or feel it “click” into place. Inspect the exhaust valve to see that it is properly seated.

2. Install the lever support and assembly into the case, setting it firmly between the guide ribs

in the Case.

3. Lubricate and install new o-rings & from the annual service kit onto the orifice . Install

the orifice back into the orifice housing using the fingertip. Use the adjustor knob to turn the

orifice counter-clockwise fully, until it stops.

NOTE

: Prior to this point, you should have cleaned and inspected all parts, following proper servicing

procedures. Do not continue until this has been done.

NOTE

: If only the lever is to be replaced, do not totally remove the screw. You can remove the lever

from under the screw when the screw is almost all the way out.

NOTE

: If you use an ultrasonic cleaner to clean the second stage adjustable orifice , use a plastic

container to prevent the orifice from vibrating against other metal parts which could damage the orifice seal.
