Stage(fig 4，fig 5)

Push the cover glass slowly into the jaw, then clamp

glass gently.

Rotate handwheel to move ruler athwartships or

length ways. The specimen will be moved to a place

you need.

★Be careful to change objectives. When you have

observed the specimen with a Low-power objective

and needed to change objective, objective may

encounter specimen.

★The degree of tightness of handwheel can be

adjusted. Please Draw down handwheel A and find

two adjusting ring(B,C),then rotate ring. B is the

adjusting ring of X direction. C is the adjusting ring

of Y direction.

★the altitude of handwheel also can be adjusted.

Draw down handwheel A and D can rise integral

handwheels. You can also adjust it to negative

direction and rise handwheels.
