[@ComradeDylan49]

Can the Dirt Blaster attachment be used on a wooden deck? Or is is only recommended for stone?

[@bigtedshome]

I don't have any decking so can't speak from experience but I suspect that the dirtblaster lance might be too aggressive for wood. Karcher recommend using a surface cleaner if you have one www.kaercher.com/uk/home-garden/how-to-guides/pressure-washers/patio-deck-cleaning.html

[@lugassydavid]

Hi! Thanks for the eplanation.
Quick Question, how do you enter Mix Mode? Because on the lance it's just Soft - Hard.. Thanks!

[@bigtedshome]

Hi David, to go into mix mode you just turn the vario lance to minimum power (fully clockwise). Alternatively, if you use a foam cannon or simply remove the lance, the k4 will enter mix mode.

[@lugassydavid]

@@bigtedshome thank you!

[@jocelynmeehan5995]

Thank you. Really impressive. Just a query on attaching the water hose. Is it just a click into the machine?

[@bigtedshome]

If the hose is not already attached to the machine, you push it into the back of the machine and there is a U shaped metal clip that holds it in place. This video shows how to remove and fit a hose to the K4: czcams.com/video/_mPLwbM-vvQ/video.html
I hope this helps 🙂

[@jocelynmeehan5995]

Thank you so much

[@Sara-fx1or]

Thank you, just need to know hoe to attache the water!

[@bigtedshome]

You need a connector like this on the end of your garden hose: amzn.to/4c440bD
It then pushes onto the water inlet (towards the bottom LHS as you look at the yellow front of the K4). Hope this makes sense 🙂

[@beverleynorth4914]

Very helpful video
Do you need to pull the hose through the slot before attaching the lance?

[@bigtedshome]

You don't have to pull the hose through the slot. Personally, I found it easier not to. It's fairly straightforward to disconnect the lance from the hose if you want to try both options.

[@beverleynorth4914]

Had 1st go today with new K4. Patio T5 cleaner is a game changer. Very impressed with it. Have to watch out that it doesn’t pick up bits of gravel, etc.
Did you have 2 spare screws?? They go in the long dowels that fix the base in place.
What are best mods, improvements for it. Hose?? Then what?

[@bigtedshome]

@beverleynorth4914 Thanks for the info re. the screws, I did get there eventually (with help from others on here) 🙂
The hose is the first thing I would upgrade. Then if you intend to wash cars, I would recommend a short trigger gun and a foam cannon. There are videos featuring all of these upgrades on my channel.
This video is important czcams.com/video/F125OkLZwJo/video.html as is not storing your K4 anywhere where the water inside it could freeze as the expansion could crack the pump.

[@Thiscrime]

Appreciate your time and effort to make this video, I just finished assembling thanks to you and off I go now with the T5, just a question, do I need to remove the detergent after I use it or it lock when I am on hard setting.?!

[@Rewind787]

Fantastic video, just what I needed, thank you. I do have a (very amateur) question with regards to the setup. I have recently had an outside tap fitted, however I haven't needed to use it yet, so I haven't bought any hoses/connectors/adapters. My question is, what do I actually need to buy in order to attach to the outside tap to the Karcher machine itself. I know that a hose will be needed, but with regards to the connectors I am a little clueless being as I have never needed one before. Any help (and possibly a website link to which product(s)) would be very much appreciated. Thanks so much.

[@bigtedshome]

Thanks for the great feedback. To connect your pressure washer to your outside tap, you will need a tap connector to screw onto your outside tap, 2 hose connectors, a hose and I would recommend a hose reel. Assuming a 25m hose will be long enough for you, this kit contains everything you should need: amzn.to/4a1HUoB
Also available at Screwfix if you don't use amazon: www.screwfix.com/p/hozelock-2-in-1-reel-with-hose-25m/63087

[@roderickwho1983]

Hello Big Ted. Thanks for the video. After assembly of my K4 I have 2 small screws left over. No idea where they're supposed to go....
What would you nozzle/power setting would you suggest for cleaning wood stain and bird droppings off a wooden deck ? Thanks.

[@bigtedshome]

Hi Roderick. As far as I'm aware there should be 8 small screws, 2 go into the top of the lance holder, 4 hold in the lance visor and 2 to secure the handle. Watch the video between approx 4:20 and 5:40 to see where they go. I'm sorry but I don't have any decking so can't really help you with your second question. I would think it would depend on the condition of the wood and would suggest starting on the lowest power and working up.

[@roderickwho1983]

Thanks Big Ted. I'll take your advice regarding the pressure settings.
WRT the leftover screws: my instruction bucklet shows a picture E and refers o two screws "b" and "c", but for the life of me I can't find the location pictures ! If the pressure washer flies apart when I start it up I'll know I dropped the ball :-)

[@bigtedshome]

I don't have my assembly instructions anymore but I can't see how any of the screws would affect the safety of your pressure washer. They are just used to attach the peripherals like the lance stand and handle. I would just give all of these a pull to make sure they are secure before using it. Good luck 🙂

[@bigtedshome]

@DonDomDomi If the paving is really dirty, I would use the Karcher stone cleaner that was supplied with the K4. In most cases though, I just use water. The block paving shown in the video was cleaned just using water.

[@DonDomDomi]

[@juicer404]

Do u add detergent to unit or just spray on surface

[@bigtedshome]

If you are using the triangular karcher detergent bottle, it plugs into the top of the machine. If you are using a different detergent, just spray it on.

[@James_08_07]

How did you get the hose to pull through the hole when unwinding? Mine kinked severely about 5 times on first use. I've given up and the hose no longer passes through the hole in main Assembly, I just coil it up and hang it on the back.

[@bigtedshome]

I gave up on it as well after a while and did the same thing. After battling with it for 6 months, I changed the plastic hose for a 10m reinforced rubber hose and found that upgrading made a big difference. This video shows how I did it: czcams.com/video/_mPLwbM-vvQ/video.html

[@James_08_07]

@@bigtedshome Amazing! I think I'll do the same. Honestly, why on earth did they make that the standard hose, terrible decision!

[@bigtedshome]

@James_08_07 I assume they chose the plastic hose it to keep costs down. It lets down what is otherwise a great machine.

[@gavbrown9808]

How do I get the gun handle when using the patio cleaner to go to the hard setting?

[@bigtedshome]

You can't as far as I'm aware. The k4 selects the correct pressure when you attach the patio cleaner (it does the same thing if you attach a foam cannon). You can adjust the pressure by turning the dial on top of the patio cleaner.

[@rapiddd3469]

Is it normal if I have two screws left over? It’s the longer screws and there was only two of them.

There's a comment below (from Mozgar) that might help. I suspect that your two spare screws should be used to screw into the 2 long pins that push up into the stand.

[@nikolaykarcher]

Несколько советов, чтобы Ваша мойка Karcher прослужила как можно дольше. 📌
Постараюсь перечислить по пунктам (не в порядке важности, они все важны).
1) Прочитайте инструкцию по эксплуатации и соблюдайте её (это для сильных духом):))
2) Ставьте дополнительный фильтр, регулярно очищайте внутренний и если есть, внешний фильтр. Следите за чистотой воды, избегайте грязи и абразива.
3) Соблюдайте режим работы. Давайте остыть аппарату минут 15-20, если непрерывно моете более 1,5 - 2 часов. Это если у Вас К5-К7, если К2-К3 то каждые полчаса.
4) При мойке старайтесь реже отпускать-нажимать клавишу пистолета, сократив при этом количество срабатываний клапанов и микровыключателя на остановку.
5) Не мойте горячей водой. Для минимоек серий K2-K5 максимальная температура воды 40C. Для K6-K7 60C.
6) Храните мойку в тёплом месте. Если храните в холодном, сливайте всю воду, при возможности закачивайте антифриз.
7) Не оставляйте аппарат под давлением на длительное время. Если делаете перерыв в мойке на 5 минут - стравливайте давление, нажмите клавишу пистолета. Обязательно после мойки не забывайте стравить давление!
8) Не используйте интегрированные в корпус моек бачки для химии. Не поскупитесь на пенную насадку, и используйте её для нанесения шампуней. Если всё же наносите химию через Керхер, то обязательно после каждой мойки промывайте систему чистой водой. Химия (особенно агрессивный бесконтакт) не очень хорошо воздействует на внутренние элементы и детали насоса.
9) Следите, чтобы мойке хватало воды. Модель серии K5 потребляет около 8 литров воды в минуту. В Вашей системе водоснабжения при работе всегда должно быть достаточно воды. Для подключения используйте шланг на 3/4 и длиной не менее 10 метров.
10) Следите за напряжением в сети, оно не должно быть менее 220В. Если бывают перепады - используйте стабилизатор соответствующей мощности.
11) Очень аккуратно эксплуатируйте Ваши аксессуары к Вашей мойке Karcher, они стоят очень приличных денег. Не бросайте, не наступайте, не наезжайте машиной на струйные трубки, пистолеты, шланги.
12) С любовью и нежностью относитесь к купленной Вами дорогой технике, как советский дедушка к своему ВАЗ 2101 :)) и она ответит Вам взаимностью.

[@bigtedshome]

Thank you Nikolay for this excellent advice. Comment 12 made me smile 🙂

[@sslalaninz]

Hi Big Ted, thanks for the video. I am thinking to buy this unit but am unsure about a point, please see if you could help. The intention is to clean house/building walls using K4, how good it is to clean walls, and how high the water could go? Would it cover a two-story building with sufficient pressure to clean the high-reaching areas such as the eaves? Many thanks

[@bigtedshome]

The K4 is excellent for cleaning walls but you would not be able to clean a two story building with the supplied lances. The lance needs to be close to the wall to have enough pressure to clean it and using the lance from a ladder would be too dangerous. Karcher do make a telescopic lance which would appear to be ideal for your application. You can find he details here: amzn.to/3qycYb8

Do you mean that you can't connect a hosepipe to the k4? If so, you will need a hose end connector on the end of the hosepipe. This will then push onto the water inlet towards the bottom left (as you look at it from the front) of the k4.

How long did it take to do the whole patio ???

[@bigtedshome]

I think it took a couple of hours.

How come I can’t connect the end of the hose into the handle? It comes out at the slightest tug and when the water turns on it leaks everywhere

[@bigtedshome]

The hose has a quick connect fitting which should click into place when you depress the yellow trigger and push the hose in far enough. Release the trigger and give the hose a good pull to test if it is located properly before turning on the water. It can take a few attempts to locate the hose fitting in the handle correctly but once it is secure it shouldn't leak.

This was two years ago - I wondered if you still use it? Did it keep working?

[@bigtedshome]

It's coming up to 3 years now and I've been very happy with my K4. Changing the stiff plastic hose for a rubber one made a big difference. There are a few other K4 videos on my channel that might help you decide if this is the pressure washer for you.

@@bigtedshome Too late - the box is sitting downstairs. 👍
Glad to hear it.
I've also already ordered a new hose thanks to another of your videos.
Cheers. 👍

@@M123OCT Just be careful. Pressure washing can become addictive 🙂

Bro k3 pressure washer can I used in 220 voltage I am very confused please telling me?

[@bigtedshome]

If you look at the K3 specifications on the karcher (kaercher.com) website, it says that the voltage it needs is 220 to 240V so it should be OK. To be sure, you could email them to check it will work using the power supply where you live.
