My name is Robert and i'am from Holland.
My german is not so good,so i write in english.
I'am building an Komatsu pc490-11 from Fumotec.
The problem is that the hoses from the boom to the servo's constant grinding against the frame or fold.
I hope there is someone who can help me with a picture of how its done.
I put a few pictures here and hope it clears the problem.
