    Tips: Oil-Sealed Vacuum Pump Maintenance

    1. Keep the vacuum pump clean and prevent foreign matter from entering the pump.

    2. Keep the oil level. Do not have the pump run without oil.

    3. Keep the oil clean. If it becomes dirty, muddy or has water or other volatile substances that affect the ultimate vacuum, the oil should be changed. Before changing the oil, start the pump and run the pump for about 30 minutes to make the oil thin, and then stop it and drain the oil from the oil outlet. Then run the pump for 1-2 minutes with the air inlet open. During this time, add a small quantity of clean oil from the air inlet port so as to replace the remaining oil in the pump. Do it again. After making sure the pump is clean, put on the oil drain plug and then fill clean pump oil to the oil-level line from the oil filling port.

    4. If the vacuum pump is not used for a long time, put on the oil filling cap and exhaust cap, and keep the pump in a dry place. At the same time, the pump should be well protected against moisture and rust.

    5. If the pump needs disassembling and fixing, please ask for assistance from an experienced or professional technician.
