2.To shut down your pump after use
To help prolong pump life and promote easy starting.
for shut down.
( 1 ) Close the manifold valve between the pump and the system.
( 2 ) Remove the hose from the pump inlet.
( 3 ) Cap the inlet port to prevent any contamination or loose particles from entering
the port.
TO MAINTAIN YOUR HIGH VACUUM PUMP
1.Vacuum pump oil:
The condition and type of oil used in any high vacuum pump are extremely
important in determining the ultimate attainable vacuum. We recommend the use of
High Vacuum Pump Oil.This oil has been specifically blended to maintain maximum
viscosity at normal running temperatures and to improve cold weather starts.
2.Oil Change Procedure
(1)Be sure the pump is warmed up.
(2)Remove the OIL DRAIN cap. Drain contaminated oil into a suitable container
and dispose of it 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 exhaust fitting 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 180-800ml(reference the technical
data).
(5)Be sure the inlet ports are capped, then turn on the pump. Allow it to run for
one minute, then check the oil level space. If the oil is below the sight glass OIL
LEVEL line, add oil slowly (with the pump running )until the oil reaches the OIL
LEVEL line. Replace the exhaust fitting, making sure the inlet is

a)If the oil is badly contaminated with sludge that forms when water is allowed
to collect in the oil,you may need to remove the oil reservoir cover and wipe
it out.
b)Another method of dealing with heavily contaminated oil is to force the oil from
the pump reservoir. To do this, allow the pump to run until it is warmed up. While the
pump is still running, remove the oil drain cap. Slightly restrict the exhaust. This will back-
pressure the oil reservoir and force the oil from it, carrying more contamination.
When the oil ceases to flow, turn off the pump.
Repeat this procedure as required until the contamination is removed.
Replace the OIL DRAIN cap and refill the reservoir to the proper level with
fresh pump oil.
