are smooth and positive. Mechanical stage, and rack stop serve to
minimize damage.

SET-UP
1. GETTING THE MICROSCOPE READY FOR USE
First, familiarize yourself both visually and physically with the mechanical parts of your microscope. Gently
operate each part by hand (no tools required) to see how it behaves and what result it produces.
2. MOUNTING THE OBJECTIVE AND EYEPIECE
To put the eyepiece in place simply slide it into the eyepiece tube. The objective lenses screw into the rotating
nosepiece. If the four objectives are already mounted in the nosepiece, check to see if they are tightly in place.
To do this, grip the knurled ring on the objectives with your fingers and turn it to the right. Do not tighten them
with tools, they need only to be “finger tight”. With all four objectives mounted in the nosepiece the entire nose
-
piece can be rotated by hand. As you rotate the nosepiece you will notice that each objective lens has a “click
stop” which stops and holds the objective lens being used in its proper position relative to the optical axis of the
microscope.
3. ILLUMINATION
In order to provide illumination for your new microscope, simple plug the power cord into an electrical socket
and switch your microscope “ON”, and you are ready to begin working.
