Notes on Replacement ・Bearings have a front and back. They will still function even if the orientation is reversed. ・For the first few uses, apply a heavy oil such as lever oil or key oil to the bearings each time. The oil will settle in, and the clicking sound will decrease. ・When using the included screws, use a 1.5mm hex wrench. You can also reuse the original screws. ・S-shaped rods are not supported. Please make your own judgment at your own risk. If replacement is difficult, please ask a music store for assistance.
