If you want to protect your investment as I'm sure everyone would want to take care of their Wagner Airless Sprayer system. Use care when cleaning it:
Warm soapy water for LATEX or water based products; and mineral spirits or lacquer thinner if cleaning sprayer after using oil based paints, stains or sealers.
Be sure to preserve sprayer between uses with pump preserver or just plain WD-40--it will save you a lot of headaches when you pull it out to use after its been sitting 10 or 20 months.
