When do I use which tip?

When do I use which tip?

These are the 5 most commonly supplied nozzles. The White 45 degree nozzle is the best choice for cleaning wood surfaces. The reason is that the 45 degree fan delivers the pressure over a larger area which is less injurious to the surface of the wood in comparison to the others. Further note, the nozzles have been color coded for not only the sake of identification but also in order of their intensity on a surface. Red = Strong and Dangerous, yellow = Caution, green = Ok, white = safest. The black nozzle utilizes the lowest pressure a machine can give.

How do I know which size orifice to use to change the pressure of my machine?

Use a chart to determine your machines current output with regard to its GPM rating, then select the nozzle size that gives the pressure you are looking for in relation to your machines gpm. A chart is located here: http://www.dultmeier.com
