container and dispose of properly. 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 flow of oil has stopped, tilt the pump forward to drain
residual oil.
4. Replace the OIL DRAIN cap. Remove the OIL FILL cap, and fill the
reservoir with new vacuum pump oil until the oil just shows at the
bottom of the sight glass. The approximate oil capacity of the pump is
13 ounces.
