Hi Mike, Is the pressure of this model adjustable only through the gun or can you adjust the pressure on this cat pump as well?
Mark

Answer
There is a regulator between the spray gun and spray lance to allow you to dial down your pressure. There is ALSO an unloader valve on the CAT pump allowing you to adjust the pressure there as well.
