Install the black, large–orifice, chemical tip. (
Instal-
ling and Changing Spray Tips
page 15).
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 chemi-
cal injector and produces high pressure for rinsing.
The chemical filter can be left in the chemical container
during high–pressure use. To regulate the flow rate of
the chemical, turn the chemical adjustment knob on the
injector.
