To mount the tracing ball on the individual func-
tional tray of the maxilla:
▷ Select long or short tracing ball depending on
space vertically available (here: Tracing ball,
long [4]).
▷ Screw tracing ball together with lock nut [4a]
about halfway into tracer mounting.
This leaves enough threads in both rotation
directions for subsequent adjustment.
▷ Protect the threads of the tracing ball facing
towards the palatinal side with wax or a piece of
the plastic hose [12].
▷ Screw in retention screws [3a] of tracer mount-
ing [3] to the stop. Insulate the threads with
vaseline (petroleum jelly).
