Rubi Rubi tvh 200mm

[GoneGuy]

hi all,
I got a rubid nd200 and put a rubi tvh 200mm disc on it,
I've noticed it makes a whistling noise is this normal?
Also it doesn't seem to cut straight but a slight curve on it, I have taken it off and cleaned the boss and put it back on and seems the same.
Anyone had any of these problems?

Not used a tvh blade what ever that is, not had that problem with any blades in my nd200.
Might be worth checking the blade to see if it's bowed.

It's the Rubi blade blue one (turbo) , I'll check tomorrow.
Thanks for the reply
