A single press of the white Manual Sample button during Standby, selects the current oil
circuit for sampling. Subsequent presses of the button are used to toggle through and
select a different oil circuit from the three available. Once a circuit is displayed, the timer
automatically counts down from 10 seconds and if the white button is not pressed again,
the listed circuit is selected for manual oil sampling. After the count down an oil purge is
performed as shown in Figure 6—13.
