Questions & Answers

Will the unit come with oil?

When purchasing new in box, will the unit already have oil in the engine and some fuel in tank? Also, does it come with the detergent siphoning tube?
Asked by: Damian
Yes, all Dewalt preessure washers come with a container of oil. They also come with a chemical siphon tube and filter.

My Dewalt DXPW4200 PSI pressure washer only puts out 3200 psi

The adjustment knob is turn all the way down and it puts out only 3200 PSI. I can't find out how to turn it up. I paid for a 4000 psi washer not a 3000 psi washer need help. When I first used the Dewalt DXPW4200 it seam low on PSI. I ordered a inline gauge to check the pressure to see if I was right and I was.
Asked by: JKR
Pressure, horsepower, flow rates, etc., are always inflated above real-world performance. Same deal with vacuum cleaners, air compressors, motors, pumps, etc. It has always been thus. At best these numbers are useful only for comparing one model relative to others. Unfortunately this is the only way a manufacturer can compete, because they all do it.

Is this model good for vinyl siding homes. Or is this machine too powerful for siding. Do u have psi 4400 or higher.

Asked by: Me
ME, this will work on siding and the 4200 PSI is the largest machine available in the Dewalt line up.

ARE YOU ABLE TO HOOK UP ADDITIONAL HOSES TO IT SO TWO PEOPLE CAN WORK AT ONCE?

ARE YOU ABLE TO HOOK UP ADDITIONAL HOSES TO IT SO TWO PEOPLE CAN WORK AT ONCE?
Asked by: Zak
I believe so,, if one could make the plumbing manifold to divide the output in 2 -- Although you'll probably see a pressure and water volume drop -- Point is,,, one person will move twice as fast as two lower volumes and psi flows,,, and 2 people at reduced volume will move twice as slow than one,,, -- So what's your point in doing this

Honda GX390 4,200 PSI 4 GPM Gas Pressure Washer is rated 4.3 out of 5 by 127.

I purchased one and it was supposed to NOT have oil in it, and therefor I put the oil that came with the unit in as well without checking to see if it had any in it.. causing it to be overfilled and blew out a seal.. they swapped it out for a new one without issue. its a good, powerful unit however, it is a little hard to start.. it would be great if it had an electric start. my smaller dewalt unit that is identical looking, starts first pull overtime. overall great units!

Rated 5 out of 5 by from C I converted this power washer into a water jetter for clogged drains. Out of the box and after prepping it started on the first pull. I tested it on a few things, it ripped through a old Rubbermaid bin. This machine has lots of power. After setting it up ive used it on two sewer clogs and performed perfectly. Im very satisfied.....so far.
