Install Instructions

VACUUM PUMP OIL:
• The condition and type of oil used in the hilmor Vacuum Pump are extremely
important to achieve deep vacuum. For premium performance, use
hilmor Vacuum Pump Oil, which is a low-vapor pressure oil that improves
vacuum performance and cold weather start-up.
• For best results, change the oil after every hilmor Vacuum Pump use.
OIL CHANGE PROCEDURE:
For best results, drain oil from the hilmor Vacuum Pump immediately after evacuation
to ensure that the pump is still warm and contaminants are still suspended in the oil.
1. Turn hilmor Vacuum Pump o.
2. Remove the oil drain plug, drain the contaminated oil into a container and
dispose of it properly. Tilt the hilmor Vacuum Pump forward slightly to remove
the residual oil.
3. Reattach the oil drain plug. Remove the oil fill cap, and fill the oil reservoir with
new hilmor Vacuum Pump Oil until oil level has reached between the Min and
Max markings on the sight glass.
4. Replace the oil fill cap.
IF OIL IS BADLY CONTAMINATED, FOLLOW THESE STEPS
TO FLUSH:
1. Drain any oil in the hilmor Vacuum Pump, following the steps above.
2. Remove the oil reservoir for cleaning by removing the four screws that hold it
to the hilmor Vacuum Pump.
3. Remove the oil reservoir and wipe with a clean rag.
4. Reassemble the reservoir by carefully placing the gasket into the groove,
being careful not to pinch the gasket.
5. Replace all four screws by tightening to 106 in–lbs (12 n-m), and make sure
the oil reservoir is tightly attached to the hilmor Vacuum Pump.
6. Refill with oil and check for leaks.
7. Let the hilmor Vacuum Pump run until it is warmed up.
8. Turn the hilmor Vacuum Pump o, then change the oil following the steps above.
