
There is no vacuum pump oil of the newly delivered machine. Please fill the oil for
its first use.

Check the color of the vacuum pump oil
The vacuum pump oil is bright and clear without any foam or muddle. If there are white
materials after precipitation, it indicates there are foreign materials in the oil. Please do
replace the blackened vacuum pump oil or the oil with foreign materials.

The service time of the vacuum pump oil
The service time of the vacuum pump oil depends on its working environment. To
extract clean and dry gas, the vacuum pump oil should be replaced every 500 working
hours normally or at least once every six months.

Check the oil level at least once every week. Observe the oil level through oil
indicator and add oil if the oil level is too low.

It is suggested to replace the vacuum pump oil-mist filter at the same time when
replacing vacuum pump oil.
Keep the pump running for several minutes before replacing, to get a proper
temperature of the oil and the pump, so that the wet air and the impurities can be
better absorbed and filtered. High temperature will volatilize the wet air in the pump to
reduce the rust.

Replacing oil

Open the back cover.

Place a basin for oil under the oil-drain hole.

Unscrew the oil-drain plug with wrench in correct size.

Drain the oil.

Put the oil-drain plug back after oil-draining.

Dispose the waste oil as the environmental protection law regulates.
Note: When you unscrew the oil-drain plug, the oil flow through the oil-drain hole, so
there should be a basin for oil. At the end of the oil-draining, please lean the
machine slightly so that the residual oil can flow away.
