6 Maintenance and Troubleshooting
Do not allow oil to rise above the midway position when the pump is run-
ning. Doing so may cause oil to splash into the oil filter causing con-
tamination.
7. Check the washer or O-ring used at the oil-filling port and replace if necessary.
8. Insert the oil-fill plug and turn clockwise to tighten.
9. Check the alumina in the oil vapor trap. If most of the pellets are no longer white,
replace the alumina before reattaching the vacuum pump. See "Replace the Alu-
mina in the Oil Vapor Trap" on the facing page.
10. Reconnect the vacuum pump hose.
11. Reconnect the power cord to the power source.
12. Turn the vacuum pump on and recheck the oil level.
13. Allow the pump to run a few hours (overnight if possible) to eliminate air and mois-
ture from the fresh fluid and to produce efficient vacuum operations.
