How to repair Harbor Freight Krause & Becker Paint Sprayer System. Failed to prime and spray. 

Just took mine out after only using it once, had the same problem. Did what you did and WALA!!! It works again! Great video. I would recommend a different sprayer, wasn’t too impressed with this one.

Dude!!! You are incredible and amazing. I woke up this morning to use my sprayer and same issue as what you encountered. I did exactly what you did but used WD-40 instead cause I was too lazy to get the other oil. And it's running great again. You totally made my day!! Thanks for uploading this!!!

Thanks to your including it won't prime with no spray hose you helped me so much, I had my whole sprayer ripped apart, all I needed was a hose and a gun hooked up thanks man!

This worked! Thank you! Mine sat for almost 4 years broken, then I found your video and it fixed it. Thank you :)

Thank your for showing how to rescue the air paint sprayer!!!

OMG! Bought this thing 5 years ago. Never used it. Super bummed it didn't work. Tried this and it works!! Thank you!!

Thanks for the videos... I bought one of these last year, built a small cart for it and then it rained every time I tried to use it. Will be using it for the first time this morning.

Thanks for putting up both of these videos on the sprayer. We plan on doing some home renovation this year and I've been thinking about purchasing it. One tip I read someone else mention for storage is to use Graco Pump Armor.

Your fix was spot on. I am back up and running or should I say spraying!! Thank you Thank you. Thank you

My problem was exactly the same as yours. Your video helped me corrected the problem quickly. Thank you very much!

Thanks for taking the time to make this. Very helpful!

You just saved me $200! I had this exact same issue. I always make sure to clean the whole system really well so I was perplexed as to why it wouldn't work after I used it a year ago. Unfortunately, just adding oil didn't work for me (no air bubbles and the level didn't drop over time). So, I put a piece of plastic sheeting over the inlet hole and zip-tied it on tight so that it would hold pressure. Then I put the spring and ball-bearing back in and screwed the piece back on. The process of screwing it on created pressure and since the inlet hole was covered the oil was forced into the pump. As soon as I flipped it to prime it shot the oil out of the outlet port and I knew I was back in business. I had actually already purchased a replacement one and this was my last ditch attempt before opening it up. Thank you!

This worked for me. I needed to clean out twice before it started working. Thank you for posting.

My pump didnt squirt the oil out like yours but I reattached everything and tried to prime anyway. I had to keep pushing and holding the pressure release button to finally get it to prime. Much appreciated!

Thank you. Took a few tries but worked. My model had a pin with no ball barren so had to be wait for the oil to bubble down . I used duct tape and my garden-hose to prime and flush as well.

You ROCK man, you saved me from having to go guy a whole new one took like 3 minutes. And YES it was my fault for not oiling it. I always say I'll do it when I get home and then you get busy. It's a great piece of equipment for the price, just take the extra few minutes to take care of it right!

Thanks! My sprayer had been sitting for 5 years and wouldn't prime. The ball and spring were worse than yours, but the oil made prime immediately. Great tip.

Thank you my friend You solved my problem I appreciate 🙏

Thank you!!!! This worked! You're my new best friend 😍

Thanks, sir. I have the same problem with my K&B. Used once a year ago. I'll use compressor oil tomorrow and give it a go.

Thanks for taking the time to make this video. I hope it works for me too.

Because of this video, by this most excellent man, I followed instructions that allowed me to complete my project. My old "paint gun", I thought was toast . . Renewed!

I've been using mine for staining a LOT of a large fence. Got about 10 hours on it already. Agree with the change of tip size. The absolute key to any sprayer using soap and water for cleanup is to make sure not to store it with water anywhere in the system. The 'recommended' Grayco Pump Armor is NOT necessary. Instead, use any kind of automotive anti-freeze. It's cheap and coats all the parts inside with an anti corrosive. Mix it down to 50/50 if you want. After hose is clear from cleanup, disconnect that and the gun. Prime with anti-freeze then switch to spray. As soon as you see it coming out, shut it down. That's it. Also recommend taking the gun completely apart - clean really good with soap and water. Let it dry or force compressed air thru all parts of the gun. As you put it back together, I use WD-40 and squirt it everywhere -- inside, all parts, tip, spray needle, screen filter, trigger - everywhere. Then store in a Ziploc bag with a final spray of WD-40 and seal the bag. And, yes, this is a good sprayer for the price -- I've had zero issues with mine. When I'm done with it (even for just a couple of days) I'll 'pickle' it as above. All hoses look brand new after each use -- takes less than an hour to fully clean it for short or long term storage.

Same problem with mine. Your fix worked great for me. Thanks!

Great video, thanks! Worked like a charm!

Thank you so much I was ready to throw my sprayer to the garbage God bless you

Awesome advice it worked right away

I just found your video, you just saved me some money. I did exactly what you did now it works fine Thanks.

Thank you this helps God bless you

That is great! Thanks!

Thank you. It worked 👍

Good video.....

Thank you so much!

thank your video help alout I'm going to try ...SEE IF I GET THIS SPRAYER GOING

Worked for me. Thanks. Used veggie oil as I didn’t have compressor oil

Awesome thank u

Excellent video. Thank you for showing how to repair the unit. Compressor oil! Do you use the compressor oil in the sprayer unit, while in storage?

Thank you for the tip

question...what goes first the steel or the spring? and does it come with a rubber ?

worked!

Thanks! Mine will prime, but it's continuously runs when I'm not spraying. Put it up dry 5 months ago, smh!

Mine just stays on and air comes out bottom how do I fix

I noticed that even when I switch mine to prime there’s still some pressure going into the outlet paint hose. When I switch toggle to spray it does stop any paint from coming out the prime tube. Any of you have this same issue?

Hola para que se oprime el botón rojo. Es que compre uno igual y me podrías decir como lubricar el piston. gracias

how do you get the gun filter out thru the bottom like it shows in the manual. the harder i pull, the more the spring stretches. i know you got yours out thru the top but i can't get it loose.

Just take off the suction screen from the suction hose turn it upright and fill with water replace the screen and prime works everytime for me.

Have you had problems with the clamp for the mesh screen on the suction tube rusting?

Is there a replacement hose that will work on this from another brand?

So I used my machine and stored it for about 4 days. Went to use it with a think brick paint. It sprayed for about 3 minutes than it wouldn't spray. Is paint to thick where it wouldn't go through machine or sprayer?

I am having the same problem. How did you get the steel ball out? Mine seems to be stuck, almost glued in, I've tried loosening it with acetone, thinner. It wont budge. The button on the button seems pressed in and stuck.. bought the sprayer used. Was clean outside, but inside was a mess. I've gotten it all clean and clear except this part. It's almost completely disassembled and I cant the ball out.

Same here, 1 lil project

Same thing with mine after one use. Thanks for uploading this. PS..I think mine was closer to 200 bucks. lol everything is more in california.

Maybe someone can help. I only use mine with water as many detailers are doing. With mine the pump wont shut off .. the pump should only kick on when spraying. Mine keeps going ... any ideas ?

Hi there! What size socket is needed to remove the nipple? Mine is stuck and won’t unscrew with a wrench.

Tengo una de las mismas amigo pero no sé apaga automáticamente y chirpea la pintura ayúdame con información de cómo reparar esa falla

Are you still happy with this? Would you buy different now? I'm looking to buy a painter, I'm just a homeowner not a pro, and trying to wisely spend my precious few paint-equipment dollars. Thank You.

How do you take off the pressure knob

donde hay repuesto de esas maquina

Where can get the ball ring? Thank you

So I've only used this pressure washer one time. ru-vid.comUgkxfQauTxLT0JLSvqkq10rD79TU4k0Vz8zP The one time I used it, it worked great. I recently had new siding installed but kept the old gutters and small areas surrounding my house that weren't replaced so they looked horrible and dirty because of the new siding. I needed to get it cleaned asap. When I used the pressure washer, man it just melted all the dirt and grime that was on those areas of my house. I used that krud kutter soap and it was over after that. Easy to assemble, feels durable, very simple to use. Also, I purchased a used one to save money and there was absolutely nothing wrong with it. I want to get more use out of it so I think I'll be washing the cars and update this comment as time goes on.

tip on sprays out on sides not middle

Where can I find new tips for the sprayer?

No comprastes la garantia de 20 dolar por 2 años
