Hello Bertram28,
We are sorry to hear about your frustrating experience with the X7. We are thinking that perhaps the tip size you were using was too small for the primer you were trying to spray. The X7 can support up to a 0.017 inch tip, such as a 517. The tip that ships with the X7 is a 515 with a 0.015 inch orifice. Spraying a material that is too think for the tip will result in continually clogging the tip. Using the correct size spray tip would eliminate your clogging issue. Another recommendation would be to strain the paint. That is always a good idea.
As a side note, all of our tips are made at our factory in Sioux Falls, SD. Our tips are the best on the market and are made to highest quality standards.
Also, the motor does not run constantly. Our airless sprayers only run the motor as needed to maintain the pressure.
If you do run into issues again, we ask that you give our Tech Support team a call so that one of our experts can help. They can be reached at 889.541.9788 M-F 7:30-5:30.
