Align the holes of the O-mixer and N-wheel axle, and then insert the D-split pin.
Fold the split pin if necessary.
Install one K-support pole, one G-short spring, one H-gasket, one J-wheel, and
one H-gasket into one side of the axle in order, and then lock them with I-M12 nut.
Pay attention to the orientation of the J-wheel. Repeat the steps for another wheel.
The steps for the rest wheels are similar (not having the O-mixer and K-support
pole).
