Setting the Stage's Stop-Limit

1. Unlock the stop-limit, which is the switch inside the left hand focusing knob.

2. Adjust the stage to the desired maximum height.

3. Lock the stop-limit. This will allow you to limit the movement of the stage from the bottom of the range up to

the point that it is set at.

4. To reset it, unlock the stage and reset the stage to the new height that you would like it to limit at. If no limit is

desired, simply unlock the stop-limit, but be careful when using the oil immersion lens (100x), as with no limit you

can hit the slide, damaging the lens or your sample.

1. To adjust the tension of the focusing knobs, first locate the black ridged tension knob on the inside of the coarse

focusing knob.

2. To decrease tension, rotate the adjustment forward, towards the stage (counterclockwise). To increase, rotate

away from the stage (clockwise).

Note: If your stage is slipping down after setting the focus, you need to increase the tension.

1. Before changing the light bulb, first pull the plug out of the electrical socket and wait for the lamp to cool down.

The light can get hot when a halogen system is in use, so please be careful to avoid being burned.

2. Grab the base section and pull forward to remove the cover around the light.

3. You may now change the bulb by removing and replacing it. Be sure that the bulb is not hot before touching it

to avoid burning.
