fat from unprotected fingers and scratching the sealing surface.

end.

Screw the adapter rod onto the adapter. Tighten by holding the adapter rod with a
wrench and then tighten with the hook wrench key hand-tight only. For the 100
column only: Hold the adapter rod with a wrench and then tighten using another
wrench.
The parts can loosen after using the column several times. Check that the
adapter rod is tight before performing each packing procedure.
Note:

If necessary, remove and replace the O-ring [104] in the adapter rod top.
This O-ring does not normally suffer from wear and its replacement is a
difficult procedure.
Note:
7
Fit the adapter rod top onto the adapter rod and (i) tighten the three lower screws
so that the rod top is centered on the adapter rod, and then (ii) tighten the two upper
stop screws [106] with an Allen key to fix the adapter tubing in the adapter rod.
CAUTION
After the adapter rod top has been fixed to the adapter tubing
do not loosen the adapter from the adapter rod. This may cause
leaks inside the adapter rod resulting from the adapter tubing
coming loose.
