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.

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 4.4 out of 5 by 114.
Rated 5 out of 5 by from Great pressure washer I bought mine several years ago and it has made me 100x's the cost back in jobs done. The Honda motor is worth the extra cost, another thing is it came with a cat pump which is one of the best pumps on the market. The gun was lacking in quality but I changed it out for a professional one after about a year. It needs another 25 ft of hose so you don't have to move machine as much. Cost for additional hose will run you 69.00. I also recommend getting a 10ft extension wand for doing houses saves a lot of time getting on a ladder. Overall after 3 yrs of use would I purchase this machine again, yes definetly.

Rated 5 out of 5 by from Great set up easy use and pump parts are easy... Great set up easy use and pump parts are easy to find and replace. Have bought 4 of these units and they are all still running. You can use the Honda engine with a triplex pump with a pulley system. Unfortunately the shaft driven pump parts wear out from a commercial industrial use stand point.

Rated 5 out of 5 by from Great washer Washer has plenty of cleaning power. Easy to roll on uneven surfaces​. Large fuel capacity. Fueled it up and added the oil,it started on the 3rd pull . It died out when I squeezed the wand.I restarted it and let it warm up and has worked and started great since. The only wish I would have is an easier to use hose. The hose is stiff and hard to roll but I guess that's part of having a 4200psi washer.

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.
