My Dual monitor Workfit A with worksurface was installed last week and I am having problems with the whole unit tilitng forward about 30 degrees. When it is all the way down it will stay flat for a time frame then the whole arm will just tilt forward. Tilting the monitors, worksurface, and keyboard tray causing everything to fall on the floor. In the standing position it is constantly tilted forward to the point where it is unusable. I can force it down flat and I can work in the sitting position, but if I attempt to rotate or move any of it, it will once again pop up and tilt forward. I have attempted adjusting everything, but I'm not sure what exactly I should be adjusting. Please help.
