Hello we recommend washing your nozzle insert with warm water after every use.

Hello thanks for the question, if you also know the flow rate of your machine you can work out the required nozzle size by using our online nozzle sizing chart. The chart itself just lists 175 bar across the top but this should be ok to use as a reference. Simply move down until you reach your flow rate then look at the corresponding nozzle size figure in the green box on the left hand side for your size. You don't need to click on the boxes because all Turbo nozzles are pencil jet and do not have angles. www.gspen.co.uk/interactive-nozzle-chart

Hello thanks for the feedback, just wondering if you are pumping up the sprayer enough?

Hello, thank you for your question. You may have a nozzle that is too small for the flow rate and pressure of the machine. Our nozzle sizing chart may be able to help www.gspen.co.uk/interactive-nozzle-chart

Hello, If you are based in the UK you can buy this from our large network of distributors. You can use our distributor locator here www.gspen.co.uk/distributor-map

Hi if you can explain a little more we may be able to help.

Hello, sorry to hear this it should unscrew like the demonstration video shows. You may need to take this back to your supplier to see if they can help.

Hello son 😊😊

Hi David as a general rule ensure that the surface of the fitting is clean and free of dirt, oil, grease, moisture, and other contaminants.

No problem thank you for the feedback.

Hello, as the O'rings come as part of the valve kit, we take them out to inspect anyway, so might as well replace them at the same time as a preventative maintenance measure.

Hi no problem, yes Loxeal 55-03 will be good for this.

Hello Gerry, you should be ok to leave the product in the container for next use. Although we would advise that you depressurise the unit and if you wanted you could give the nozzle insert a rinse.

Hello, I feel we may need to produce another video with a closer shot of the paint being removed from the container. You can clearly see the black paint being removed at the start of the video. However you are right it doesn't highlight the paint coming off the container very well.

Thank you, yes this is a good replacement for PTFE tape.

Thanks for the question. With the nozzle screwed directly into the ST330, everything should lock into place at 60bar. Any extension piece out of the swivel, adds weight/force, which then doesn't allow it to lock safely at 60bar.

Hello Mark, the ST160 should work with the Northstar pressure washer, and should be fitted to the outlet of the machine using the relevant QR system. Unfortunately the K1700 doesn't produce enough flow for these to work. The minimum flow reuired would be 2.3gpm/10lpm

The soap is injected by a RM Suttner ST160 chemical Injector attached between the hose and pressure washer outlet. The ST75 foam head enables low pressure which creates a vacuum/venturi effect which opens the chemical check valve inside the injector introducing chemical to the water stream. When changing from ST75 foam head to rinse lance the pressure is too great for the venturi effct to take place within the injector, this means you can rinse off with no chemical being mixed with the water. hope this helps.

@@GSPenrithLTD good to know. Also, I understand that the injection ratio is already set but do we have to use a specific pressure washer?

@@markevanado9463 Hello, they are designed to work on commercial and industrial pressure washers over 10lpm and running at more than 80bar. They will also only work on pressure washers that dont already have an injector fitted internally.

@@GSPenrithLTD how would I connect this to a northstar 230v 2500psi/3gpm on demand?

Hello Mark, thanks for your question. The K-lock is fitted to the newer Karcher machines which come with easyforce threads. They are not M22 as per older models.

Hello, thank you for your comment. Yes you are correct you can simply remove the ST75 foam head and easily attach your high pressure rinse lance and no chemical will be drawn. We have a chemical injector chart to help you select the correct chemical injector and foam lance for the flow and pressure of the machine you are using. Take a look www.gspen.co.uk/interactive-foam-nozzle-chart

@@GSPenrithLTDis the number 20-250 on the top row the pressure of your pressure washer in bar & the left side column the flow rate of the pressure washer?

@@wd8005 Hello yes this is correct.

@@GSPenrithLTD Can I ask where did the chart come from? Is it your own calculated chart or is it directly from Suttner?

@@wd8005 Yes the chart has come from RM Suttner. We have developed the chart to make it interactive for our website.

Good afternoon Thank you for your enquiry With the ST167 1.8mm version you ideally need the 2.1mm (13) nozzle in the ST75 Foam Lance Too small a nozzle will create too much back pressure which won’t drop the pressure enough to activate the valve in the injector. Too big a nozzle will give you a wet foam, and you may get liquid pouring out the front of the lance, rather than through the nozzle. www.gspen.co.uk/interactive-foam-nozzle-chart

@@GSPenrithLTD I can't thank you enough!!!!

@@GSPenrithLTD what about the rinsing nozzle? If I choose to put a 11 size nozzle will there be accidentally sent foam too?

@@chrisracer2007 Foam may come through if the lever on the ST167 hasn't been touched. The ST167 is designed to allow full flow of clean water through it when the lever is put in the correct position, so even with the size 11 it should be ok.

@@GSPenrithLTDif I wanted the st-160 how could I make it work.... It doesn't have the bypass lever!! I would not like to choose a bigger orifice as the flow would exceed 26 liters per minute and the st-75 can't handle it which would mean that I would have to check out other solutions ($$$). To sum up should I risk it and go with the st-160 or play it safe with the st-167

Hi, we certainly can. We will do a demonstration video soon.

Hi Emma apologies for the slow response the lance is 800mm.

Hi yes this is no problem we will do this video this week. Watch out for it early next week.

Hi Juan thanks for your question. Where are you based ?

With gun and lance. Full set

@@jitchem757 Hi thanks for your question. If you wish to buy this kit we will happily put you in touch with one of our distributors. Feel free to contact us anytime on 01768 865985

Thanks for your question. The coloured collars are used more as a reference and help to distinguish between two different chemicals when using a twin chemical injector.

Hi Jeff thanks for the feedback. There is another video to follow, this will go into more detail about the different foam produced from each insert. Subscribe to make sure you dont miss it.

Thank you, If there are any proucts you would like us to demonstrate or produce maintenance video's for just let us know.

@@GSPenrithLTD can u do a video arround kew spigot setup thanks you

@@McCaithnessfilms thats no problem. Could you give us some more detail on what you would like to see ? The spigot itself is relatively straight forward to assemble.

@@GSPenrithLTD I meant like building the gun and info about the different between standard lance and Kew spigots

Hi Krystian, the nozzles need to be at an angle for the surface cleaner to be effective. This allows the swivel bar to rotate more quickly.

Hello Vinu, The nozzle in the video is 65116 1/4"F which has 3 rear jets and no front jet. The nozzle in the thumbnail picture for this video is 200049805

Hola, lo siento, mi español no es genial. ¿Quieres saber cuál es la mejor boquilla turbo para usar?

Si

@@franklinbautista4736 Es importante que se utilice el tamaño correcto de la boquilla para el flujo de la bomba y la presión de funcionamiento.
