I watch the entire video even though i dont have plans on buying a pressure washer. IDK. It relaxes me. HAHA
lol
I farted out my ass
@@xenomorph7299 i mean where else do you fart from
I'm only here to keep the yearly comment streak. 👍
@@thatonekid8685 you dare ask
Wow, I’ve seen a lot of videos on different topics but this one goes to exactly how the unit functions and the caveats associated with poor maintenance. Most excellent presentation.
Compliments on the obvious intelligence and organization that went into this video's production. Unlike so many others, this video did not waste one second of my time while viewing. On a scale of 10 . . . you get a 20 from me.
I only came here for how a pressure washer works but also included how an engine works even if it was needed liked it
It is definitely a useful product! We're glad you like the video.
Pressure washers are awesome! Very powerful. Glad you liked the video.
Great video...does a great job explaining everything from head to toe on the washer. My 3 YO really loved the fast portion of the engine combustion. I had to play that part over and over. :0)
We're glad you found it informative and we're happy we could entertain your 3 year old at the same time :-)
Thank you
Thanks for the comment and for the suggestion!
Thank you! Think are explain with clarity.
GREAT VIDEO

amaaaaaazing thanks to you i will majorer ma cti tank u very much
tank you very moche
of course every one know zat u are the GOD of the cti
This is very well done, top notch, I’m just looking for the wand specifically, my wand is leaking like a geyser out of the trigger. I’m changing the o rings but I’m doubtful that will be my only issue.
Very informative video. Thanks 🙏

A normal well pump is designed for pressures between approximately 30 - 60 pounds of pressure. A pressure washer pump is designed for much higher pressures approximately 1500 - 3000 or more pounds of pressure depending on the model. A pressure washer pump is designed for low volume of water but at a high pressure. You need to use special nozzles with a small hole to produce the pressure.
You did a good job on how a 4 stroke engine works, but limited info on how the pump works. Like how much hp is needed for a certain pressure and gpm. Why does the wand have to be so long? Does a longer wand increase pressure?
If anything, it would be the wand's tube inner diameter responsible for the output pressure..
IME, a long wand is a good thing (giggity!) because you want to be back from the high pressure water, or you'll get even wetter than you already will. Plus, the wand is sized about right to spray the ground in front of you without stooping, assuming you're of average height.
@@bcubed72 Your a nut! Please don't reply back that saying that's where all the pressure is created🤣🤣
Moving water will not freeze and the pump will keep warm when it is running. The problem is when it is turned off. You would need to put some pump saver in the unit each time the unit is shut down. Remove the pressure hose and drain all the water out after each use or store it inside your house. The pump saver part # is 1941855 on our website.
very informative great vedio thank you
It is possible the unloader valve is stuck and not releasing the pressure. Don’t get this mixed up with the thermal release valve they are two different things. The unloader valve recirculates the pressurized water back through the pump to avoid damaging the pump.
great video, i was using this today at work it was really fun!!! CLEANS ANYTHING. i was also having a bit of fun with it shooting it in the air :p
You can remove the unloader valve and see if the engine will turn over. If not you might try removing the pump from the engine to determine if it is the engine or the pump that is not turning. The unloader is most likely under a cap and will need to be pulled out to see if it is working properly. You can look at one on our website for reference. Part # 1971071 although this may not be the one for your unit.
The higher pressure nozzles do not let enough water pass by the injector venturi to draw the chemicals. We can't recommend altering the manufactures design. If you put a tube on the inlet side there won't be enough water passing thru the hose to draw chemicals unless a larger nozzle size is used on the high pressure side. The other thing you need to think about is if you put chemicals in the inlet side, compressing the chemicals could potentially be dangerous and the chemicals can harm the pump.
I like that you just jump right to replace the carb instead of cleaning it.
Great video, very useful and informative...I use the product itself, and it's awesome! Work become effortless and I recommend it to my friends to buy it also :)
U guys should make a video on how an electric powered pressure washer works. And really good video u guys are the best.
You taught me things
Love this channel
What do you mean by a normal pump?
Do you guys have a video about how a Four wheeler engine works? If not I would like to request a video like that because I am big into engines.
+cat vs dog We do not have a video for that product type at this time.
So being an internal combustion engine, how is the heat dissipation controlled? Cars have a cooling system, what do these have?
That is completely dependent on what brand and model of pressure washer you own.
I pulled a GVC 160 out of the trash last night. I just got done cleaning the carb, it fired up on the 4th pull. Now I need to ops check the pumping system.
Most small engine carberators can be rebuilt as well by the user most home improvment store washers are of 3 brands kholer, briggs and Stratton or honda many small engine places have em if u have to have it going that same day it has alot of small parts so many coose to replace but common issues are vowl float failure and nozzle clogging
I noticed that in the animation when you pull the starter rope, the flywheel spins the opposite way from the way that you pulled the cord. It should turn clockwise and not counter-clockwise.
actually it's going right way
Never going to buy or use one. Idk, does anyone else like videos like this because the narrator speaks with such certainty. I need this kind of structure in my life. He’s just spitting straight facts, I don’t question it. It relaxes me for some strange reason. Makes me feel like someone is in charge. If there is a God, he sounds like this narrator.
when I'm spraying water and I release trigger on the wand it keeps spraying this is a problem with the wand correct. just wanted to know before I buy a new one
+steven Reed The gun is probably defective.
What would cause my pressure washer to not crank? This is my first time using the product and was working fine until it ran out of gas. So I let the engine cool for a bit, added gas and then pulled on the start cord. Nothing budged. I did release the pressure at the hose trigger, even disconnected the water hose from the unit. Still the crank shaft will not move. I suspect the pump still has high pressure inside and that is why I am not able to crank the engine. Any suggestions?
What's the difference between normal pump and pressure washer pump?
How does the HEAT relief valve work ?
Why does a chemical injection location have to be on the outport pipe? I have a gas/portable prssure washer I need to use to spray my 35 ft tall trees. The low pressure option to suck treatments squirts maybe 10'. I need to mix the trtmnt into the high pressure shooting 40 to 50'. The car wash sprayers have an option for soap and etc. I need to make a pitot tube attachment at the water inlet. Comments ? Options? how tos?
how long works with a gallon of gas?
Well, like normal house pump(idk. what's the name), and jet pump.
4:19 is when the video starts. I appreciate your detailed information but telling people to skip four minutes if they know what an electric motor is and how an engine works.
Hello,
I´d like to buy a underbody lance for an AR Blueclean 610. This pressure washer has the specifications of 1885 PSI (130 bar) and 2.1 GPM (8.3 L/min) and it has a valve to adjust the pressure water. It has the VARI-SPRAY NOZZLE HEAD AL413R (I couldn´t find the orifice size data of it). I´d like to ask you about the exact nozzle size: do I have to consider the maximum PSI and GMP for select the correct nozzle for the lance? In this case the nozzle size will be 3.5. What about the other pressure achieved with the adjustable pressure valve? For example, if I adjust it to 1000 PSI, will I have to change the nozzle tip to another (example: 4.0)? or always I have to use the same tip with its orifice size related to the MAXIMUM PSI and GMP even when I decrease the pressure? Thanks a lot in advance.
The correct terminology is 4 Stoke, not 4 cycle. A cycle is a course or series of events or operations that recur regularly and usually lead back to the starting point. Note that is states leads back to the same starting point. To use cycle to represent ½ revolution of the crankshaft, (which is what you are doing), means that at the end of every ½ revolution, the same set of events will occur. This is not true; a different set of events occur next that when they are completed, a different set of results then occur. This happens every ½ revolution of the crankshaft, which equates to the piston moving either upwards or downwards in the cylinder one time, an action called stroke. It takes four such piston movements for the engine to fire a cylinder, hence the term 4 stroke. You prove my exact explanation of why it's called 4 stroke starting at 7:38 when you describe what happens inside the engine in order for it to run. Oh, BTW, vacuum does not draw air into the cylinder, atmospheric pressure at the throat of the carburetor pushes ir through it and into the engine. Although you probably state it that way to simplify it for people that don't know how a internal combustion engine works. At least I give you kudos for not ever calling it a motor.
A 2 stroke engine accomplishes the same events, (albeit in a different way using less parts), in two ½ revolutions of the crankshaft; hence the 2 stroke term. Each stroke consists of a series of events that without the other(s) that are necessary for the engine to run, do not constitute a cycle. Why the change of terminology to use a word that is totally inaccurate doesn't make sense. Does stroke offend some people?
i seen you don't have parts to simmm presure washers
Not currently, no.
Dang lots of problems with these things... if there was only a air compressor powered pressure washer that itself had no moving parts. No pump, or motor. One anybody could make themselves. The king will solve this age old problem. I'll call it... The king's power washer gun. An air compressor powered pressure washer! You are welcome to check it out, and invited to leave a comment. Have a great one!
It's a simple design
Can't "recommend it" ? gotta cover ur self....lol..... Besides that, we see the pressure whasers at the car wash allows soap and etc to come on high pressure, how is that system plumbed? Thee is a way to plumb it. Can anyone here instruct where or how that is done? Thanks!
to start, as i pull the string, it jerks back. what causes this and how can i fix it?
There are a few possible causes for this. Enter your pressure washer's model number in our website's repair help system for model-specific troubleshooting and repair help: www.repairclinic.com/repairhelp?TLSID=1773.
The Honda HP wash, and almost anyone, are 2 stroke engines and not 4 strokes.
They are wrong on the gas tank you never close the black cap if you do pressure builds up in the tank and will eventually explode
We wanna know how the pressure washer system works not how an internal combustion engine works 😅
I shoot my hand with the 0 degree tip today on a job. Holy shit that hurt.
Yikes!
Sorry, I am laughing and the first thought through my head was, "IDIOT!" LOL. We may not all admit it, but we all have done that at one time or another. I was using the 22 degree tip and that hurts pretty good to. My washer is 2700 psi so the 0 degree would probably rip skin and bore a hole into my hand..
It's good to have a pressure washer at your house cause you wont have to go to the car wash and use there pressure washer.
1500-3000 pounds, about 750-1500 kilos, never expect that.
No explanation on hot water systems works
mines broken
Always wondered how these work. You could skin an animal with one of these
They are definitely powerful!
I'm going to buy a pressure washer only for the purpose of going to dirty places and washing them, not even going to ask just doing it
I didn't ask how a 4 stroke engine works !!!!!
Now we use electric pressure washer
I clicked on this to learn more about power washers not about gas engines. Thumps down
