Karcher K5.80

Hello,

I've just bought a Karcher K5.80 pressure washer refurbished, i tried it and it works but the noice is really loud like a screetching sound. The power of it is superb but the noice makes me not want to use it.

Is my pressure washer faulty?

Here is the video of the sound

Thank you

Mike
