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

5.3 ASSEMBLY OF SECOND STAGE
1. Re-install the cleaned and lubricated O-ring onto the adjustable orifice . Install the
adjustable orifice back into the orifice housing. Push it in with your finger as far as it will go.
2. Install the exhaust valve into the case by inserting the nipple into the small hole 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.

that the Blizzard and Oasis style lever assambly will be installed with the heat transfer fins
still attached. The fins must be installed into the mouthpiece on the correct side of the
locating tabs in the top and bottom of the mouthpiece tube. When looking through the case
mouthpiece tube from the outside (mouthpiece end) the fins must be on the right side of the
locating tabs. Screw the orifice housing onto the threads of the lever support . Use a 6"
or 8" adjustable wrench to tighten the orifice housing onto the lever support assembly snugly
70 in. lbs. (8 joules).
