This pressure washer features an engine that should be run at full throttle. If the throttle is run at less than full, the pressure washer pump will not produce its max output(gpm and psi).

Question

Couple of questions - Does this unit have an adjustable engine throttle? An answer to another question about true psi - does that mean that 3300 psi

in standby changes to 3000 because of the pressure drop when the water starts to move when spraying? Is this how all PWs are measured, in that the advertised pressure is always the standby pressure? If the detergent injection is downstream, does that mean it's not going thru the pump, and is mixing with high pressure spray constantly, and can that injection be turned off? Many thanks! Richard

The NorthStar Cold Water Pressure Washer does offer adjustable pressure setting of the pump. Also, various pressures can be achieved by using a different nozzle pattern. All pressure washers are rated by the standby pressure which will decrease when in operation.
The downstream detergent injector will flow after the pump. This will not flow through the pump. The chemical is distributed by using the chemical nozzle that will provide low pressure only. After the chemical has been applied, the chemical nozzle will be replaced with the high pressure nozzle to continue pressure washing.

How low can the pressure be set?

Since the CAT pump on this unit has an adjustable pressure regulator I am wondering how low the pressure can be set?

The pressure when turned all the way down is approximately 450-500 PSI. To get an accurate PSI reading we recommend a pressure gauge item#32154.
