Changing the oil in a mini compressor, like using it, is not very complicated and can easily be done at home. In general, you should change the oil once a year, even more often if you use the compressor frequently.
Be sure to switch off the Mini Compressor before you start changing the oil!
It is also important that you use oil recommended by the manufacturer. If you do not take care of the compressor or use the wrong oil, the unit may break down and the warranty may be voided.
The process is very similar to changing the oil in a car, so it's best to follow these simple steps:
Drain the old oil: First you need to provide a container for the used oil. Then place the container under the oil drain plug so that there is no mess. If you want to make the job easier, you can use a suction pump or a suction syringe. Both are available separately and do not cost the earth.
