I just did Maintenance on Both of my PCP compressors, First the Spritech and then the GX, very easy to do, I took the cover off, removed the copper tube compression fittings, removed the top valve cover, pulled the valve spring and seal out, removed the top head and cleaned all gunk off, removed the top cylinder and cleaned, removed the lower cylinder and cleaned all crud, cleaned entire piston assembly, inspected all parts and seals, replace seals as needed, lube all parts with Synthetic oil, I used Royal Blue Synthetic Compressor lube, Reassemble exactly how it came apart, you should be able to do this maintenance in about 30-45 minutes, depending on brand and ease of access to the piston cylinder.
Don't forget to grease the piston rod or shaft and crank bearing.
Good luck and Happy Shooting
