How to replace the vacuum pump oil
1. Run the pump for about 3-5minutes until it is warmed up to runs out the pump oil.
2. When the pump is running, open the air inlet port at the same time to let the oil flow
back to the oil tank. The pump must stop when replacing the oil.
Stop the pump and open the oil drain plug. Then open the catcher to speed up the
process of oil exhausting.
3. Tilt the pump body to completely drain the residual oil, and tighten the drain plug.
4. Open the catch device and add the new pump oil.
5. Cover the air inlet cap and start the pump to run-check the oil level after one
minute.If the oil level is below the lower limit, slowly add the oil until it reaches the
normal oil level. Finally, screw on the catcher.
