Thanks for the post EppNation!

BTW we have a breakdown of this compressor at the below link:

mastertoolrepair.com/portable-oilfree-ai...-b3511-p-747247.html

There isn't any maintenance needed for the oil-free pump itself, as the piston (compression) ring has a Teflon coating and doesn't need any maintenance.

The maintenance I would perform is to drain the air tank after you use it, every time. Keeping compressed air in the tank creates moisture, and this can eventually rust out your tank and create a pinhole leak, usually where the drain valve threads into the tank as this is where the steel is the thinnest.

Make sure your pressure gauges are accurate and there are no leaks after the unit shuts off. It's typical over time for the in-tank check valve to stick, thereby back-feeding air through the lines which can make the unit difficult to start and can create air leaks. As long as your tank constantly holds air, you're good.

Otherwise:

- Before storing the compressor for a prolonged period, use an air blow gun to clean all dust and debris from the compressor.
- Disconnect the power cord and coil it up. Pull the pressure relief valve to release all pressure from the tank (as mentioned above) to drain all moisture from the tank. Clean the filter element and filter housing; replace the element if necessary.
- Cover the unit when not in use to protect from dust and debris.

I hope this helps!
