two digits are the spray angle.
*The chemical injector tip is brass and has a larger
opening and a black plastic cap.

3. Without holding your hand over the spray tip (A), pull
back the quick coupler ring (B). Remove the current
tip. Install a different tip. Push quick coupler ring
back into place.
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, deacti-
vates the chemical injector and produces high pres-
sure for rinsing. The chemical filter can be left in the
chemical container during high pressure spraying.
To regulate the flow rate of the chemical, turn the
chemical adjustment knob on the injector.
