Getting ready to blow
Attach the bottle to the Cannon’s screw in intake, being careful to not cross-thread it, then shake it well with your thumb over the adapter tip to stop it splashing out.
Now attach the Cannon to the pressure washer, turn on the water, then power it up.
For the thickest foam possible, turn the Cannon’s top blue air adjustment knob clockwise towards the “-” symbol. If you desire less foam or wish to use less foam solution, turn it the opposite way towards the “+” symbol.
