Thank you for choosing sears I would be happy to help you with your wine cooler. Upon researching model MCWC50DST; Check oil level in the crankcase daily. Remove the oil fill

Plug .The oil level should be even with the top of the fill hole and must not be allowed to be lower than 3/8" from the top (6 threads) at any time. It is recommended that the oil be changed after every 100 hours of operation. To drain the oil, remove the oil drain plug and collect the oil in a suitable container. Be sure to replace the plug securely before adding new oil. Use a special compressor oil such as Sears 9q6426 or SAE

20-20W SF motor oil. (Crankcase oil capacity is 16 fluid. If the drain cock valve is plugged, release all air pressure. The valve can then be removed, cleaned, and reinstalled. After the water has been drained, close the drain

cock (turn clockwise). The air compressor can now be stored.

I trust that this information will help you, thank you have a great day.
