Okay, there are two allen bolts nested in the end. You will install and remove the crank arm with the inner one. The outer is for removing the extractor. You assemble the crank in the BB, mount this arm and tighten it down until you hit probably 40nM.
This system does not set preload or spacing for the bearings. You accomplish that with spacers and a single wave washer on the left side. So either you have the spacers or you'll need to go and get them. Assembling without spacers will allow you to estimate what you'll need. Put a roughly equal thickness on both sides.
