Laser wash 4000 tri foam

[Matfry]

Trying to figure out 2 things the tri foam will spray out but the red and the blue also drip straight down off the head what causes that air pressure or bad heads then next problem is when tri foam is being applied sometimes the bridge goes all the way back to end limit instead off stopping behind car. Any help is appreciated thanks matt

Both problems could be related. Is the dripping hitting the Tbar eyes? We added a shield over the eye on the t bar to keep foam from dripping on the eye.

If you havent changed chemical or air settings, try Cleaning the foam generators. They can clog over time affecting your foam.
