Change Vacuum Pump Oil
For maximum vacuum pump performance, change
the vacuum pump oil after every 10 hours of
operation.
1. Select SETUP MENU. Scroll to MAINTAIN

The display shows how long the vacuum pump
has operated since the last oil change and
the amount of time remaining until the next oil
change is needed:
VACUUM OIL TIME: XX:XX

CHANGE VACUUM PUMP OIL NOW?
SELECT YES TO CHANGE OIL OR NO TO EXIT
2. Select YES. The display shows
WARMING OIL FOR BETTER DRAIN.

Allow the vacuum pump to run until it
automatically stops. This will take approximately
one minute.
3. The display then shows
DRAIN USED OIL AND ADD 5 OZ OF NEW OIL.
PRESS NEXT TO CONTINUE OR EXIT TO ABORT.
Refer to Figure 15, and remove the plug from
the oil fill port. (The pump drains faster when
vented.)
4. Remove the oil drain fitting cap, and drain the oil
into a suitable container for disposal. Replace
the cap.
5. Attach the flexible tube/cap to the oil bottle (from
the accessory kit). Pour only five (5) ounces
of vacuum pump oil into the fill port. Note: You
will top off the oil in the next step as the vacuum
pump is running.
6. Select NEXT. The unit displays
FILL VACUUM PUMP WITH NEW OIL UNTIL
THE LEVEL REACHES THE MIDDLE OF THE
SIGHT GLASS.
REPLACE CAP AND PRESS EXIT WHEN
COMPLETE.
While the vacuum pump is running, slowly add
oil until the level rises to the center of the sight
glass.
7. Install the plug in the fill port, and select EXIT.
Review the laws in your jurisdiction
to determine the correct disposal
procedure for pump oil . It is the
responsibility of the user to determine
if a material is a hazardous waste at
the time of disposal. Ensure you are
in compliance with all applicable laws
and regulations .
