Need help with assembling a QU-AX QX

[Kal]

Hey!

I recently bought a QU-AX QX (my first own unicycle) and I am a little embarrassed to say this, but I cannot figure out how to assemble it. I have looked in the manual and all over the Internet to no avail. There's a YouTube video that shows how to assemble a QU-AX, but it's a different model and it doesn't seem to work the same way on the QX.

Basically, what I can't figure out is how to attach bearing holders to the the fork. It seems to me that the screws are too short. And on the video I saw the bearing holders had grooves in them that prevented the screw from spinning, but there are no such grooves on mine. I also have no idea what tools I need.

So if anyone can help me out here that would be greatly appreciated!
