OPERATION and MAINTENANCE
PRE-OPERATION
In all cases, motors are designed for operating voltages plus or minus 10% of the normal rating. Single
voltage motors are supplied fully connected and ready to operate.
1.
Check the On/Off switch to be sure it is in the OFF position before you plug the pump into an outlet. Remove
and discard the exhaust cap from the end of the pump’s handle.

to ON. When the pump runs smoothly, replace the cap on the inlet port. This may take from 2-30 seconds
depending on the ambient temperature. After the pump runs for approximately one minute, check the sight
glass for proper oil level. The level should be even with the sight glass oil level line. Add oil if necessary.
NOTE:
To help prolong the pump life and promote easy starting. Follow these procedures for shutdown.
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.
MAINTAINING YOUR HIGH VACUUM PUMP
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 V
acuum Pump Oil. This oil has
weather starts.
Oil Change Procedure: Be sure the pump is warmed up. 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.
the sight glass. The approximate oil capacity of the pump is 180-800ml.
Be sure the inlet ports are capped then turn off the pump. Allow it to run for one minute then check the oil level
space. If the oil below the sight glass oil level line add oil slowly (with pump running) until the oil reaches the
If the oil is badly contaminated with sludge that forms when the water is allowed to collect in the oil, you may
need to remove the oil reservoir cover and wipe it out.
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
oil.
