Maintenance
General
Wipe with damp cloth to clean the exterior.
Do not use solvents.
Storage
Empty or replace oil at the end of every job.
Don’t leave old oil in the machine. Store the pump
and oil in dry clean areas for longest life.
Oil can lose its sealing properties if left
uncovered. Keep oil sealed until it’s ready for use.
Vacuum Isolation Test
Perform this test to ensure your vacuum pump
and your micron gauge are working properly.
1. Connect your vacuum gauge directly to a port on your pump.
2. Seal the 3 other ports.
3. Ensure the gas ballast is closed (page 26).
4. Switch your pump ON to create a vacuum at your gauge.
If your gauge measures below 200 microns within 1 minute, you
know your vacuum pump and micron gauge are working correctly.
If your gauge does not reach 200 microns, there is a problem with
your gauge, vacuum pump, or both.
Oil Window Cleaning
It’s important to see the condition of your oil
as well as the LED indicators located in the oil
reservoir.
The large oil drain ball valve will typically drain
solids and sludge when changing the oil. When
it becomes hard to see through the window, you
can remove the oil window for easy cleaning.
1. Ensure oil is drained from the reservoir.
To reduce residual oil spillage, do not lay the pump on its side.
2. While holding the black bezel (frame) in place, use a hex key (Allen
wrench) to remove the 4 hex socket screws.
3. While holding the glass oil window in place, remove the black bezel
and notice the o-ring located behind the window.
4. Slowly remove the glass oil window while making sure to locate
and remove the o-ring seal.
5. Wipe away any spilt oil, but leave a bit of oil on the o-ring to ensure
a good seal.
6. Clean the glass oil window and set aside to dry.
7. If desired, you can use a light bristle brush clean out the oil reservoir
itself, but performance is rarely affected by a dirty reservoir.
8. Place the o-ring back into its groove.
9. Place the glass oil window over o-ring and hold in place.
10. Reinstall the bezel over the glass oil window using the 4 hex socket
screws. To avoid breaking the window, start all 4 screws before hand-
tightening any of them. Do not overtighten.
