 3. Slide the Drive Gear on to the microscopes fine focus drive plate so that the gear posts engage the slosts on the plate. Note: The drive gear will magnetically lock onto the plate. In some cases the microscopes find focus drive plate will be slightly warped preventing a flat fit – the flex coupler will compensate for this. 3.

 8. Lightly tighten the vertical and horizontal adjustment screws as shown. ​ Since the motor is usually self-aligning,​ this should be a good position for the drive. ​ Check the alignment by noting the drag while rotating the right-hand fine focus knob.  No noticeable drag should be felt for the full 360º rotation of the fine focus knob.  If any drag is felt other than the slight drag of the gears, loosen the vertical and horizontal adjustment screws and move the drive to a point where no drag is felt.  Then tighten the vertical and horizontal adjustment screws. 8.
