change, the following message will appear when the user enters vacuum mode:
CHANGE THE VACUUM OIL AS SOON AS POSSIBLE!

OIL CHANGE MENU/PROCESS
Under the setup menu, one of the choices is CHANGE VACUUM OIL.

(xxx.x is the current remaining time. 501.4, for example)
PRESS START TO BEGIN OIL CHANGE
When the START key is pressed, the vacuum pump starts and the display shows
a two-minute countdown. The pump runs until the countdown reaches zero. This
warms and circulates the vacuum pump oil so it drains easier. The display will
then show:

PRESS START WHEN COMPLETE
Drain the old oil and replace 5 ounces. Press START. The display will then
show:
FILL WITH NEW OIL TO CENTER OF SIGHT GLASS (APPROX. 13.0 OUNCES)
PRESS ENTER WHEN COMPLETE
After the user presses ENTER, the pump will stop and return to the start-up
screen.
