Great video as always. I think it is best to know how to fix the gun yourself in case problems like this arise (and what parts to order) rather than paying for the shipping in both ways. I did use quite a bit high vacuum grease (from Dow Corning) to prevent leaks in rubber o-rings in metal evaporation chambers, molecular beam epitaxy chambers, liquid nitrogen cooled dewers etc when I was at the grad school at UCLA. I wonder if you can use the same on the white (teflon?) o-ring, and perhaps on the barrel that slides back and forth on the plastic guide as well. Take care, Pete.
As long as the grease doesn't affect rubber, normally neoprene in these, it should be ok. Obviously, keep in mind that the area these components are in is in the air train of the gun, so only enough to lubricate as excess can come through the gun onto your work
@@peteshobbies5383 The Dow Corning high vacuum grease is "designed" for rubber (neoprene) o-rings. So, I wouldn't think even it harms a teflon o-ring. The main emphasis behind the high vacuum grease is that it does NOT degas under vacuum or pressure. I sometimes used to put this grease on threads to eliminate microscopic leaks in liquid nitrogen cooled dewers. Anyways, in your case you mentioned there might be a possibility that it could migrate to mix with your paint. However, there is always a positive pressure in the air chamber to push the grease back towards the threads. In the vacuum work, this was just the opposite where the grease starts migrating towards the sample, and we never encountered any trace of organic residue when we examined the chemical composition of gold contacts using atomic spectroscopy. I think in air guns this should work even better due to outward pressure. I wouldn't use petroleum jelly or any type of thick oil. My 2 cents.
@windsurfingphd From what I can see, the inward pressure follows on through the gun, so it would take any excess through the gun, as long as people don't put an excessive amount it doesn't cause a problem. I normally use a silicone based lithium complex grease for rubber parts but don't in the case of spray guns because of the problems that would cause
I bought WS400 at the end of last year. It´s a series 1 gun, didn´t know the series 2 was going to be launched, I have used the gun less than 10 times and it started leaking air from the front air horn. Used Sata as a hobby painter for years, was disappointed about theyr atomisation ability, never any air leak problems tho. Also bought Kiwami 4, liked kinda how it sprays solvent base and water base colors. Had quite a lot troubles to get the WS400 to spray clear. Not sure if i bought the wrong guns for me. Another choice was Sagola, regreting now for not trying out theyr guns.
Hi Jan, sorry to hear the WS400 is giving you trouble. Have you contacted the supplier you bought it from? It should be under warranty. It will be a problem with the air valve behind the trigger, letting air pass. Have you seen my videos on angling the air cap on the WS400? It makes it spray the same as the series2
I have 1.3 HD and 1.4 HD fluid tips and both of them are in 45 degree angle, so i would need to twist the air cap 45 degree. Haven´t tried it cuz i thought it would feel funny, too much in a angle. Struggling with the low fluid flow, used to that Sata will consume much more fluid.
All the split tip guns are slower than their conventional cousins. The atomisation is definitely finer, but, as you say, it's at the expense of speed, Series2 isn't any faster it just easier to use as you don't have the fan separation problems the original has when the fan is opened up
Hi Bob, yes, I have more Iwatas than anything else and most are no problem at all, this one wasn't so good although its still usable and just annoying really. I've had a couple of people say they have had the same problem with the Kiwami4, one guy say it does it sometimes and not others which is odd, thanks for watching 👍
I finally found an Anest Iwata company representative. I was sent a Kiwami4 parts list with individual part numbers. I am waiting for a reply to the availability and pricing for the individual parts for replacing the Valve Guide and Air Valve assemblies, and asked for the Repair Service Maintenance kit part number for the Kiwami4. Will update you when I hear back and learn more.
@@peteshobbies5383 The rep is sending me pricing tomorrow. They also verified there are other parts they specify for other models which also work on the Kiwami4, but has not provided those cross reference part numbers. From the schematic of the link you have shared, here is the corresponding actual part numbers: Part Number 5 - 93001640 - Air Valve Assembly 6 - 93001690 - Air Valve 7 - 93001700 - Air Valve Spring (probably never will be needed to be replaced) 8 - 93012630 - Valve Guide Assembly 11 - 93001790 - Valve Stem I did a google search on the part numbers. Some parts show up as being for the Wider2 model. One of the parts showed up as being for the Wider1 series. These part numbers should help. Discovering the cross reference part numbers would be more helpful for providing us with more choices. The rep will get back to me tomorrow with the pricing. I still have to determine if it would make sense to replace parts, or replace the gun. Some ebay sellers in my search results are getting over $50 for air valve assembly. At that pricing, the idea of replacing parts would make it difficult to repair the gun.
Hi Shaq, your not the only one, I've been replacing my W400's with Kiwami4's so i know how you feel, I would say hopefully it's a one off but this is the third Iwata to do this, at least it doesn't stop it working, it's just annoying 👍
The replacement parts pricing for 5, 6, 7, 8, and 11 are about $80. The quoted DHL shipping to my zip code was an additional $80. Unfortunately, Part 5 assembly was quoted at $31 and part 8 assembly was $18. At that pricing, and that DHL shipping was still going to be $80, purchasing replacement parts makes no sense, when another new gun would be the same cost. I only paid $153 for my Kiwami4 and that was with shipping cost included, from Japan. It is unfortunate. I have not been told the part number for a "kit" which would contain both assemblies, though I had asked 3 different e-mails, so I am not certain a kit yet exists.
Thanks for putting the prices Neal, it's often the case that repairs just aren't worth doing as in this case, if i need parts i will order them with something else as the shipping should be virtually nill
@@peteshobbies5383, the rep got back to me and informed me that there is no service repair maintenance Kit, with both assemblies, currently offered for the Kiwami4. Told me that consumers typically order the individual part they want. Unfortunately, the rep did not provide the cross reference numbered parts, of the same parts from other Iwata gun models, which could also be used to service the Kiwami4.
So nothing better there as Iwata advertized.... They said spray gun has new and better quality air valve but as we see the same plastic and cheap... I don't remember any old style W400 or LPH 400 with the same issue after only a year of low usage....
thanks Pete, very informative video , i try to fix my W400”s vale seat once, probably thinner got in from the back of the gun and worn off the o ring. You doing great, i learn alot from you, please keep doing these great video👍🏿
Hi Mate, I don't think so, I have 2 Kiwami4 BA4J versions, one came from Paintingtoolsjapan which i know is a recognised distributor for Iwata and the one with the leak, both are identical. I do have some fake Chinese guns and there are slight differences so i would expect the differences to be there on this if it was a fake. This is the third Iwata I've had this problem with, the other was a LPH80 and a W101 so it's not unprecedented, everything wears out, i get that, but shouldn't after such a short time, I spray most days now but have many guns to chose from so nothing get loads of use really
Thank you David, I spent 40 years as a mechanical engineer repairing air, electric, 4 stroke petrol, diesel and 2 stroke engines as well as hydraulics so I'm glad some of it has been retained 🙂
What is a good website link to purchase service repair parts or kits for the Kiwami 4? I am in the USA. I cannot find any schematic with correct part numbers for the Kiwami4-13BA4 with the Kiwami4-BA4J Needle and Cap set. I have checked the Anest Iwata websites from USA, Japan, Vietnam and South Africa, and not one of them offers actual part numbers or a resource of where the Fluid Adjusting Guide or the Air Valve Seat parts can be obtained, or the actual part numbers for either of those parts or a service kit part number. The websites which are available - all seem to be out of date or links within those sites do not work. Not one of the sites supports parts for the Kiwami4. Thank you.
Hi Neal, I don't know the part numbers but the instructions on the link below have a diagram with item numbers, anest-iwata.store/product/kiwami4-ba-bellaria/ Once you know the item number contact paintingtool_jp on Instagram, they can sauce any part you want, link is below instagram.com/paintingtool_jp?igshid=YmMyMTA2M2Y= Hope that helps 👍

Here is my last follow up of what I have tracked down regarding repair parts for the Kiwami4. Iwata does not sell the parts directly to consumers. If you bought the Kiwami4 from outside your country because your country doesn't allow the gun to be sold, and you do not know where to get replacement parts, here is the answer. The Air Valve Seat assembly(5) and the Valve Guide assembly(8), for Kiwami4 spray gun are the parts that fail and cause air leaks. Those same parts and part numbers are also used in the Wider2 model. So, if Kiwami4 isn't sold in your country and the Wider2 is, you can get the replacement parts. In South Africa, Iwata sells the Valve Guide assembly(8) for $31, and from Iwata USA it is $53.48. In S Africa, the Valve Seat assembly(5) sells for $18, and in USA it sells for $25.91. Likewise, the Air Valve(6) and Valve Stem(11), are the same exact parts and part numbers as the WS200 SuperNova model gun. So, if the WS200 is sold in your country and not the Kiwami4, and you need the Valve and Stem, the Air Valve(6) in USA sells for $31.97 and the Valve Stem(11) sells for $22.05. I am told the only parts used for air leak repair are the two assemblies, #5 and #8, and the Air Valve(6) and Stem(11) are not typically replaced, due to solvents wearing out the plastic/silicone seals of the assemblies. There are no Kiwami4 Service "repair kits" that are sold by Iwata, only the individual parts are, and only through authorized distributors. The two distributors from Iwata USA, I was told to go to are jbtools.com and megadepot.com. For places where the Kiwami4 is not sold, but you need to get the parts - as here in the USA, find the parts from sellers of the WIDER2 or WS200 SuperNova guns, to repair the air leak. I was told that no "local" Iwata distributor typically carries parts. Due to my research you can now find and get them, now that you know the part number/s to order. Good luck.
Hi Pete Am having a similiar problem with two Sata 3000rp’s. Getting air bubbles in cup when pulling trigget. Think it is needle packing needs replacing?
Hi buddy, normally that is air leaking past the fluid tip, I haven't used the 3000rp's but do they have a little nylon seal at the back of the fluid tip like all the Sata's i have? , that's normal the thing that causes it, they sell them in a pack of 4 or 5 normally
Hi Sataman, the 5500x still has the seal at the back of the tip, Sata put a packet of 5 in the box when new now, they are relatively cheap and easy to replace so not a worry really, would be nice to not need them though 👍
Any Sata dealer should be able to supply them, you can sometimes find them on ebay but the price is quite high, often only a bit cheaper than a pack of 5
Hi Jeffrey, only just seen this so sorry for the late reply, yes, i can get parts from Japan but it probably not worth it at the moment, i doesn't stop the gun working it just annoying really, someone else was telling me they have the same problem but it's intermittent
Hello Pete,hope you’re well mate, I have to say this is a bit disappointing as I very much like Iwata spray guns, it’s disappointing because as you mentioned it’s across several models, just hope they get this sorted out, although it doesn’t look like a huge problem, just more annoying than anything else, great video highlighting the issue
Hi Roger, yes, my thoughts exactly, I've already sold a few W400's in exchange for Kiwami4 gun's so I'm hoping this doesn't continue, as i say, it's 3 gun's I've had do it and although I'm spraying most day's I have a load of sprayguns so none get used that much in the scale of things
@@peteshobbies5383 that’s the scary part, I to have guns that get seldom use , some of mine haven’t been used in over a year as I don’t have the opportunity to do as much as I would like to, I think I would be extremely disappointed. If a gun I used once or twice developed any kind of problem like this
Great video as always. So knowing about this design issue with Iwata what would your number one pick be for a quality low volume air consumption gun to be used for smaller items.
@@peteshobbies5383 Thank you for the advice. Turns out the Meiji F55-G and Meiji Finer Spot gun are locally available at good prices. Devilbliss is harder to come by where I live. I mainly paint smaller items and don't mind taking an extra few minutes for something bigger. Have you noticed any reliability issues with these? Your insight is always appreciated.
Hi Andrew, I am impressed with the Finer Spot, a good little spray gun, very similar in output to the Iwata LPH80 in 1.2 so if you don't mind the bigger parts taking you longer it sounds like it's what you want, haven't had any problems with it but it's very early days, the Meiji Spray Guns are very well engineered so i don't anticipate any troubles
Interesting video Pete. Not had a problem with my kiwami4. Been going great. It’ll be interesting to know how much these replacement service parts are? From brand to brand, seems like some expensive guns have cheap service parts and the cheaper guns have very expensive service parts…. Me thinking in general that owning an expensive gun will probably cost less in the long run if one factors in service parts costing…. Perhaps an idea on a future video Pete, to compare these service part prices 👍
Hi mate, the part that's required is the needle guide, the bit you screw in at the back, the W400 equivalent part is £38 from sprayguns direct so i would imagine these will be similar, may even be the same part, not expensive but shouldn't be necessary on a year old little used gun, hopefully you won't get problems, I'm in the process of changing my W400's to Kiwami4's so I'm hoping to not get any more problems 👍
Hi Les, I'm growing to like HVLP, the biggest drawback of course is the air usage, haven't really found any true LVLP guns, conventional caps are a good compromise, after all, most of this is caused by the need to be kinder to the environment rather than the finish we can obtain, are you after a full size gun?
@@les1ed They claim it's LVLP but the spec doesn't say it is, pressure 24 to 32 psi, consumption 8 to 10 CFM, that's very average for what looks like a copy of a sata, looks over priced compared to many imo
You could try putting silicone or lithium grease around the brass that fits in the plastic seal, should stop the leaks. But I wonder if you will always be afraid of grease contamination when you're spraying.
Hi buddy, that's the problem really, i use a lite smear of petroleum jelly to lubricate internal components, trouble with any lubricate you run the risk of contamination and silicone would be a nightmare, i do understand the thought behind it, cheers 👍
Hi Pete, great video mate! It’s a disappointing show from iwata, these are not cheap spray guns and cheaper can do better, you can forgive it if the gun was misused in some way but I know how you keep your guns and it’s thanks to you that I split mine down and clean them after every use, but this is unacceptable really. At least you showed how you can repair the gun I’m assuming that you can get the bits, although it’s a good failure to have in a way as it doesn’t impede on the spraying performance, just a bit of wasted air. Cheers mate see you in the next one.
Thanks Steve, yeah, it's a bit disappointing really, I recommend it to a lot of people that ask so felt i had to put something up to show what happened so people know with the stuff purchased from Japan you are taking a chance re the warranty, this particular one i got off ebay and the seller isn't there anymore, all the rest I've got from paintingtool_jp who seem very good, but if i did have problems I would probably have to send it back which i fully understand, it's just an additional expense that people need to factor in if they buy from abroad, cheers mate 👍
it is surprising for a firm with such a reputation i can maybe tolerate one instance, but 3 on 3 different guns ... maybe is problem with ebay seller/s, u never know that u get genuine product, did other 2 come form ebay or from reputable store? i had similar problem with gun that is old 30+years and did not had any use in last 20+ years (my father gun) and it was kinda mid quality gun from some firm that i cant get any info now it have simpler design and i fixed it by gently warming that soft plastic/gum to soften it and make it more flexible im not sure that this info will help you or that you can fix it that way (dont know what kinda plastic it is) but you should not had to repair and thinker with "brand new" gun ...
Hi Vedran , yes, my thoughts exactly, the other guns were purchased from authorised distributors in the UK, it was a few years ago now but exactly the same problem, air leaking from the back. Of course it doesn't affect the working of the gun but it is irritating especially as the gun is so new, I am sure its a genuine gun but i have had no such problems with any other make at all, sure, things wear out but not after relatively little use, appreciate you taking the time to comment 👍
@@peteshobbies5383 If you have an exploded diagram with part numbers it's possible that the Supernova uses the same parts that you're having trouble with. If so, you'll be able to obtain these replacement parts domestically as Iwata uses the same parts for many of their guns. Iwata's unique design, where the air and the fluid are both controlled by one valve instead of two is the root cause of this problem. I've never had an issue with it on any of my Iwata's but I can see how this could happen.
Hi Sataman, the design is the same with virtually all the Iwatas as you say but the parts are slightly different, I can obtain the parts quite easily from Japan but they are quite expensive and shouldn't be necessary on such a new gun and my thinking is will it do the same next year after new parts? , I am in the process of changing some of my W400's for Kiwami4's and hopefully this isn't a mistake, only time will tell

There are no Kiwami4 Service "repair kits" that are sold by Iwata, only the individual parts are, and only through authorized distributors. The two distributors from Iwata USA, I was told to go to are jbtools.com and megadepot.com. For places where the Kiwami4 is not sold, but you need to get the parts - as here in the USA, find the parts from sellers of the WIDER2 or WS200 SuperNova guns, to repair the air leak. I was told that no "local" Iwata distributor typically carries parts. Due to my research you can now find and get them, now that you know the part number/s to order. Good luck.
Thanks Neal, much appreciated 🙏
Hi Pete
Am having a similiar problem with two Sata 3000rp’s.
Getting air bubbles in cup when pulling trigget.
Think it is needle packing needs replacing?
Hi buddy, normally that is air leaking past the fluid tip, I haven't used the 3000rp's but do they have a little nylon seal at the back of the fluid tip like all the Sata's i have? , that's normal the thing that causes it, they sell them in a pack of 4 or 5 normally
@@peteshobbies5383 Only exception is the X5500 which doesn't have these gaskets.
Hi Sataman, the 5500x still has the seal at the back of the tip, Sata put a packet of 5 in the box when new now, they are relatively cheap and easy to replace so not a worry really, would be nice to not need them though 👍
Thanks for repying Pete.
Will try Spraygunsdirect for some replacements.
Do you know anyone else that supplies them?
Any Sata dealer should be able to supply them, you can sometimes find them on ebay but the price is quite high, often only a bit cheaper than a pack of 5
Can you order a part?
Hi Jeffrey, only just seen this so sorry for the late reply, yes, i can get parts from Japan but it probably not worth it at the moment, i doesn't stop the gun working it just annoying really, someone else was telling me they have the same problem but it's intermittent
@@peteshobbies5383 ok. I hope it gets fixed
Hello Pete,hope you’re well mate, I have to say this is a bit disappointing as I very much like Iwata spray guns, it’s disappointing because as you mentioned it’s across several models, just hope they get this sorted out, although it doesn’t look like a huge problem, just more annoying than anything else, great video highlighting the issue
Hi Roger, yes, my thoughts exactly, I've already sold a few W400's in exchange for Kiwami4 gun's so I'm hoping this doesn't continue, as i say, it's 3 gun's I've had do it and although I'm spraying most day's I have a load of sprayguns so none get used that much in the scale of things
@@peteshobbies5383 that’s the scary part, I to have guns that get seldom use , some of mine haven’t been used in over a year as I don’t have the opportunity to do as much as I would like to, I think I would be extremely disappointed. If a gun I used once or twice developed any kind of problem like this
What size allan wrench did you use? Thanks
It's a 10mm Allan wrench David👍
Great video as always. So knowing about this design issue with Iwata what would your number one pick be for a quality low volume air consumption gun to be used for smaller items.
Hi Andrew, if money was no object i would say the Devilbiss DV1s with S1 cap, or the Pro lite S if budget is more limited
@@peteshobbies5383 Thank you for the advice. Turns out the Meiji F55-G and Meiji Finer Spot gun are locally available at good prices. Devilbliss is harder to come by where I live. I mainly paint smaller items and don't mind taking an extra few minutes for something bigger. Have you noticed any reliability issues with these? Your insight is always appreciated.
Hi Andrew, I am impressed with the Finer Spot, a good little spray gun, very similar in output to the Iwata LPH80 in 1.2 so if you don't mind the bigger parts taking you longer it sounds like it's what you want, haven't had any problems with it but it's very early days, the Meiji Spray Guns are very well engineered so i don't anticipate any troubles
Interesting video Pete. Not had a problem with my kiwami4. Been going great. It’ll be interesting to know how much these replacement service parts are? From brand to brand, seems like some expensive guns have cheap service parts and the cheaper guns have very expensive service parts…. Me thinking in general that owning an expensive gun will probably cost less in the long run if one factors in service parts costing…. Perhaps an idea on a future video Pete, to compare these service part prices 👍
Hi mate, the part that's required is the needle guide, the bit you screw in at the back, the W400 equivalent part is £38 from sprayguns direct so i would imagine these will be similar, may even be the same part, not expensive but shouldn't be necessary on a year old little used gun, hopefully you won't get problems, I'm in the process of changing my W400's to Kiwami4's so I'm hoping to not get any more problems 👍
what are your recommendations for lvlp guns if any I personally dont put too much faith in hvlp
Hi Les, I'm growing to like HVLP, the biggest drawback of course is the air usage, haven't really found any true LVLP guns, conventional caps are a good compromise, after all, most of this is caused by the need to be kinder to the environment rather than the finish we can obtain, are you after a full size gun?
yes but it seems the closest I can find online is the Atom X 27 i think
@@les1ed They claim it's LVLP but the spec doesn't say it is, pressure 24 to 32 psi, consumption 8 to 10 CFM, that's very average for what looks like a copy of a sata, looks over priced compared to many imo
Summitracing LVLP, Eastwood LT100, Sprayit 33000, Italco shine LVMP, Italco Gloss LVMP
You could try putting silicone or lithium grease around the brass that fits in the plastic seal, should stop the leaks.
But I wonder if you will always be afraid of grease contamination when you're spraying.
Hi buddy, that's the problem really, i use a lite smear of petroleum jelly to lubricate internal components, trouble with any lubricate you run the risk of contamination and silicone would be a nightmare, i do understand the thought behind it, cheers 👍
Hi Pete, great video mate! It’s a disappointing show from iwata, these are not cheap spray guns and cheaper can do better, you can forgive it if the gun was misused in some way but I know how you keep your guns and it’s thanks to you that I split mine down and clean them after every use, but this is unacceptable really. At least you showed how you can repair the gun I’m assuming that you can get the bits, although it’s a good failure to have in a way as it doesn’t impede on the spraying performance, just a bit of wasted air. Cheers mate see you in the next one.
Thanks Steve, yeah, it's a bit disappointing really, I recommend it to a lot of people that ask so felt i had to put something up to show what happened so people know with the stuff purchased from Japan you are taking a chance re the warranty, this particular one i got off ebay and the seller isn't there anymore, all the rest I've got from paintingtool_jp who seem very good, but if i did have problems I would probably have to send it back which i fully understand, it's just an additional expense that people need to factor in if they buy from abroad, cheers mate 👍
it is surprising for a firm with such a reputation
i can maybe tolerate one instance, but 3 on 3 different guns ...
maybe is problem with ebay seller/s, u never know that u get genuine product, did other 2 come form ebay or from reputable store?
i had similar problem with gun that is old 30+years and did not had any use in last 20+ years (my father gun) and it was kinda mid quality gun from some firm that i cant get any info now
it have simpler design and i fixed it by gently warming that soft plastic/gum to soften it and make it more flexible
im not sure that this info will help you or that you can fix it that way (dont know what kinda plastic it is) but you should not had to repair and thinker with "brand new" gun ...
Hi Vedran , yes, my thoughts exactly, the other guns were purchased from authorised distributors in the UK, it was a few years ago now but exactly the same problem, air leaking from the back. Of course it doesn't affect the working of the gun but it is irritating especially as the gun is so new, I am sure its a genuine gun but i have had no such problems with any other make at all, sure, things wear out but not after relatively little use, appreciate you taking the time to comment 👍
@@peteshobbies5383 If you have an exploded diagram with part numbers it's possible that the Supernova uses the same parts that you're having trouble with. If so, you'll be able to obtain these replacement parts domestically as Iwata uses the same parts for many of their guns. Iwata's unique design, where the air and the fluid are both controlled by one valve instead of two is the root cause of this problem. I've never had an issue with it on any of my Iwata's but I can see how this could happen.
Hi Sataman, the design is the same with virtually all the Iwatas as you say but the parts are slightly different, I can obtain the parts quite easily from Japan but they are quite expensive and shouldn't be necessary on such a new gun and my thinking is will it do the same next year after new parts? , I am in the process of changing some of my W400's for Kiwami4's and hopefully this isn't a mistake, only time will tell
Hi if you get on ebay and pay around 250$ this is chip China gun not original it all . I got Belaria and got same problem.
Hi Mate, the W400 Bellaria and LPH400 have the same problems, and so do the LPH80, W101 etc, it happens to a lot of the Iwatas
