So I checked now how this thing is called in english. It is a sewer jetter/hydro jetter and probably nearly the same one like this one hereCan you explain what you're doing here? i've heard of washing the frame by connecting a hose or something, is that what's going on? I just spend a while with a pressure washer but wonder if i'm missing a critical area and one day find i need to make a "is this too much rust" post.... i get a lot of beach sand laced with salt.
The point is while you can reach the most parts of the 200 kinda easy for cleaning the inside of the frame is hard to reach and there isn’t much drainage holes in it (probably a 20mm hole on the front part at the bottom on each side) and he doesn’t have any big open spots where you can just flush out with ease like on some pickups.
I tried with a normal water hose but the sand and stones where to heavy thats why I picked this combination (besides the fact that the Kärcher K3 is a rly weak pressure washer but for most stuff around the house and cleaning the car a bit he is enough)
So I went into the rectangular cutouts at the frame pushed the jetter in as far as I could and then went slowly out while always keeping the one bigger hole at the bottom of the frame free from blocking.
Looked pretty good and maybe in one or two weeks I will do a second rund when it got a bit warmer (April weather here, a week a go in shirt and shorts buying ice cream and on Tuesday it was snowing….).
I guess it could be a bit more challenging if you have AHC with all the stuff mounted on the side of the frame but should be still feasible.
