Airless sprayers work at very high fluid pressure. A jet of paint can inject fluid through the skin: it looks like a small cut, but it is a medical emergency, so get immediate medical attention and tell the doctor what the fluid was. Before you service any part, follow the pressure relief procedure in the manual for your exact model, switch off and unplug an electric sprayer, and wear eye protection while you work. Our pressure relief article explains the idea; the manual for your sprayer has the exact steps.
