Karcher K2.02 - Connecting the water supply and washing with detergent

Hello, from today I am the owner of the k2.02 washer. The washer works and does its job, but its operation is not entirely known to me.
1. During washing, water is fed through a hose from a tap under low pressure and often before I turn on the washer and press the trigger of the lance, the hose under water pressure will already slide off. Same when I stop pressing the trigger on the lance. Is there no way to cut off the running water so as not to fly every now and then and turn around and spill a lot at the same time?

2. I read that it is possible to wash with water and detergent. How and where is the cleaning agent poured?

There is no such possibility - connect the supply water honestly on good quick connectors.
Karcher detergent is taken with a hose from any container - look for such a hose or read the instructions.
maybe your karcher has a tray - all the more so is the manual.
Usually there is a mark on the capacity knob on the nozzle - a wide open outlet causes a large flow of water and the venturi tube causes a vacuum in the hose that sucks the washing agent.

it's like you could show which quick connectors they will be because there are a lot of them and I have an old metal faucet, unfortunately

Possibly, the option of tightening with metal bands would pass?

would pass.
Quick couplings are bought in a brass castorama - you also need to buy a nipple screwed onto the faucet spout so that you can attach the hose with a quick coupling. faucet is always replaced.
You can afford a washcloth, then a tap.
You can also buy in gardening stores - the seller is a source of information.

Basically, I have a faucet outside http://www.instalacja-wodna.snk.pl/img/w31.jpg something like this
Would a quick coupler fit there?

Dude, I have a feeling you're either joking or asking for directions.
And what do you see plastic on this valve and what do you think suggests to it?
You wrote that you have an old type faucet - this is a fairly new ball valve.
Close this topic, because it's embarrassing, unless you're blonde.
