Mount the optics and the microscope

For this section you will need:

Place the microscope onto the microscope stand.
The lugs on the microscope should sit on the lugs of the stand.
Use four M3x10 cap head screws to fix the microscope in place using the same Allen key

Take the complete optics module and complete seperate z-actuator holding each upside down, side by side.
Insert the exposed mounting screw on the optics module through the keyhole on the seperate z-actuator.
Insert the 2.5mm Ball-end Allen key through the teardrop shaped hole on the back of the seperate z-actuator, until it engages with the mounting screw.
Slide optics module up the keyhole until it is 2-3mm below the flat section of the bottom of the z-axis while keeping the Allen key engaged with the screw.
Tighten the screw with the Allen key to lock the optics in place. If the optics module will not reach the required place with the Allen key inserted, tighten the mounting screw with the Allen key engaged before firmly pushing the optics module into the required position.

Place the Upright z-actuator mount on top of the main body, triangular face of each touching one another.
Place M3x10 cap head screws into the two externally showing holes at the front of the main body and a third screw through the top of the vertical bored hole. Screw tightly into the nuts.
Place a M3 nut into each of the 4 nut traps in the z-actuator mount.
Place the upside-down seperate z-actuator with the optics module now attached onto the z-actuator mount.
While holding these together, place 4 M3x10 cap head screws into the 4 bored holes in the seperate z-actuator and screw tightly into place.
