Assembly

Assemble the lower carriage first (1). Note trapped nuts.

Then assemble the upper carriage (2).

Assemble the two halves together (3) using 6 M4x40 caps (don't forget the optoflag!). Tighten the middle two caps, keep the outer two pairs loose. When fully assembled use a piece of ø8 mm bar to set the distances between the bearings. Slide the bar between the bearings and tighten/slacken the outer two pairs of M4x40 caps to achieve a smooth, low resistance, running fit.

Assembly

Do not tighten the two adjuster bolts marked with a * in this diagram. These will be used to set the contact between the bearings and the Z shaft. If you attempt to tighten them now you may damage the bracket.
