and back out the screws which position the top ring of the dropping
mechanism within the chamber cover. Remove the six screws holding the
chamber cover and handles to the service ring, and carefully lift the cover up

exposed bottom flange of the chamber cover, and keep the flange clean.
4.1.1.2.Replacing the Dropping Chamber Cover
Inspect the chamber O-ring and sealing surfaces. Coat the O-rings with a very
light film of Apiezon L
grease, if necessary, and re-install the chamber cover
and lifting handles. Tighten the mounting screws in a star pattern.
With the chamber cover mounted, rotate the four snubber screws on the top
rod ring out until they come in contact with the inside of the chamber cover
walls. Tighten the screws equally an additional 1/8 turn and lock in position
with the locking nuts.
Inspect the top flange O-ring and sealing surfaces. Coat the O-rings with a
very light film of Apiezon L
grease, if necessary, and mount the top flange to
the chamber cover.
NOTE: Whenever the chamber cover is removed or the support snubbers of
the top rod ring are adjusted, the vertical alignment of the dropping chamber
must be checked and the level bubbles on the tripod tray must be reset. See
the section on “Leveling the Dropper”.
