## Assembly 

<img src='content_image/723015.jpg'>

All the steps described for the assembly of the microscope must be undertaken with extreme care, and without forcing the placement of the distinct parts and elements of the microscope. 

A. Condenser (10): Turn the coarse focus knob (19) until the stage (8) reaches its highest position. Turn the focussing knob on the condenser (Fig.1) until the condenser holder reaches its lowest position. Unscrew the knurled locking screw on the condenser, and insert the condenser in the mounting ring so that the aperture of the diaphragm (9) faces the front of the microscope and so can be adjusted easily. Once firmly placed in the mounting ring, firmly tighten the locking screw, and turn the condenser focusing knob until in its highest position.
