To maintain your high vacuum pump . . .
For maximum performance, Robinair recommends changing vacuum
pump oil after each use.
The condition and type of oil used in any high vacuum pump are
extremely important in determining the ultimate attainable vacuum.
Robinair recommends the use of its Premium High Vacuum Pump
Oil. This oil has been specically blended to maintain maximum
viscosity at normal running temperatures and to improve cold
weather starts.
Robinair Premium High Vacuum Pump Oil is available in handy quart
containers or in convenient gallon containers. Order by part number:
13119 — Pint (shipped 12 pints per case)
13203 — Quart (shipped 12 quarts per case)
13204 — Gallon (shipped 4 gallons per case)
1. Run the pump for approximately one minute to warm the oil.
2. Remove the OIL DRAIN cap. Drain contaminated oil into a suitable
container, and dispose of it according to local, state, and federal
regulations. Oil can be forced from the pump by opening the inlet
and partially blocking the exhaust with a cloth while the pump is
running. Do not operate the pump for more than 20 seconds using
this method.
3. When the ow of oil has stopped, tilt the pump forward to drain
residual oil.
