MAINTENANCE

The X117C and X117CLS are constructed of durable materials
which normally requiring no lubrication or periodic maintenance.
The two ‘O’ rings (2) (p/n 00951E) in the adapter (5) that seal
against the stainless steel actuating stem (1) will need replace-
ment if signs of leakage at the stem occur.

For replacement circuit board use p/n 3080206A. When installing a
new circuit board be sure that the small black and white plastic bear-
ing piece connecting the X117C main shaft to the circuit board
mounted potentiometer shaft remains in the transmitter housing. It
is not part of the replacement circuit board.
