Answer
That is a very good question- and I've sent 2 emails to Simpson asking about this and haven't heard back from them yet.
Usually with questions like this one of the variables have been changed during the bench test of the unit- for instance, a higher RPM motor will increase the performance of the pump over what the pump manufacturer publishes.
You may want to contact Simpson directly at 877-362-4271 to see what their tech staff says about their rating.

You said this unit has a cat 4ppx pump. Although this might be true, no such pump exists on the cat web-site. Why? Are you sure this isnt a 4DNX series pump? If so, please identify the whole model number of 4DNX. Thanks.

How to heck pump oil

Answer
There will be a sight glass on the front of the pump. This will be a clear window where you will see the yellow-ish color oil sitting. There is a red dot in the center of this sight glass. The oil should be at that red dot, not over or under. Figure 12, page 17 of the attached Owner's Manual will show and describe this as well.

The question I submitted yesterday was about the Simpson ALH3228-S power washer. I was wanting the capability to dial down the pressure for some work at my house. So, would I need another tip/wand to achieve that with this model and if so where would I find that?

Answer
I would recommend pairing it with the Simpson Dial-N-Wash model 82235. This unit will allow you to adjust the pressure from the gun between 1000PSI and the full 3200 PSI I have attached a link for you to view that item.
