Customer Questions & Answers

Is the pressure manually adjustable?

Asked by: cl
Update: It seems that with the pump that now comes with this machine the AAA 11.6GA13 pump the unloader knob can be adjusted to lower the pressure by turning it counter clockwise. I guess the manual has not yet been updated. Another way to lower pressure is to use larger size nozzles; the machine comes with 4.0 nozzles, 5.0 nozzles should lower the pressure to about 2600 psi with the engine running at full speed.

can I use the pressure washer and lower the psi low enough to wash a car safely

Asked by: Frank
Yes. The variety of tips as well as being able to crank the pressure up and down will allow you to safely wash a car.

Does the pressure washer require the oil to be changed in the pump periodically?

The reason that I ask is because some pumps are sealed and don't require the oil to be changed.
Asked by: ericbob2468
Yes it does , from the manual "NOTE: The Pump was filled with oil at the factory. The preferred oil is SIMPSON ® Premium Pump Crankcase Oil. If this oil is not available, an SAE 15W-40 oil may be used. Change the pump oil after the first 50 hours of operation and every 100 hours thereafter, or every 3 months." Don't worry if you can't find any 15W-40 oil that's not primarily for diesel engines I don't think there is any.

PowerShot 4,200 psi 4.0 GPM Gas Pressure Washer Powered by Honda is rated 4.6 out of 5 by 42.
Rated 2 out of 5 by from Great engine, terrible pump. This pressure washer is built for power and the engine is awesome. Unfortunately the pump is terrible. I have two of these with the AAA pumps and they have both gone out in less than 2 months. The engine is heavy duty but the pump is not. It can't keep up with professional work. The service centers I was sent to were also terrible and very shady. I would only buy these if they put higher quality more durable pumps on them in the future. The AAA pumps are garbage.

Rated 4 out of 5 by from Easy to put together. I bit hard getting started the first time but, this thing puts out excelle... Easy to put together. I bit hard getting started the first time but, this thing puts out excellent flow and pressure. I have not used it on any extensive jobs yet, but so far so good. I used it to clean a sidewalk with the whirly tip on it and it certainly remove the dirt down to the concrete. The part that holds the hose is not big enough even for the 50' Hose. How ever since they are quick connect hoses, its probably easier to store it off the unit and unroll it prior to even think about using the unit.

Rated 5 out of 5 by from Very Nice Unit I recently purchased the unit and have used it twice. The setup was simple and I was quickly ready to do the first job. The unit is powerful, I was able to clean my gutters that my previous 3,200 gpm pressure washer failed miserably attempting. I am happy thus far.

Rated 5 out of 5 by from The beast This thing is a beast. Very powerful. With the 15"flat surface cleaning disc I cleaned my driveway in no time. FYI this is so powerful you have to help pressure towards the surface or the disc will take off like a UFO.... starts with one pull, would recommend to anyone looking for power.
