3.Install the black, large–orifice, chemical tip. (Installing and Changing Spray Tips page 12).

4.Trigger gun for a few seconds. Chemical solution will begin mixing in spray pattern.

The large orifice of the chemical tip causes a drop in pressure that actuates the chemical injector. Changing back to a small orifice spray tip deactivates the chemical injector and produces high pressure for rinsing. The chemical filter can be left in the chemical container during high–pressure use.
