Replacing the Fine Adjustment Knob
(Fig. 21)
The fine adjustment knob has been attached on the right side
at the factory.
} The fine adjustment knob is designed detachable to prevent interference
with hand during manipulation of the X-and Y-axis knobs.
Usually attach the knob on the opposite side to the X- and Y-axis
knobs.
1. Using the Allen screwdriver, loosen the clamping screw @ and remove
the fine adjustment knob

.
2. Remove the seal from the fine adjustment knob screw hole on the other
side and attach the knob by reversing the removal procedure.
3. Attach a provided seal on the screw hole | of the removed fine adjustment
knob

} The fine adjustment dial

can be operated with your fingertip or finger
surface at the same time as manipulating the X- and Y-axis knobs.

Adjusting the Coarse Adjustment Knob Tension
(Fig. 22)
Adjust the coarse adjustment knob tension using the tension
adjustment ring @.
The coarse adjustment knob tension is preadjusted for easy use. However,
if desired, you can change the tension using the tension adjustment ring
@. Turning the ring in the direction of the arrow increases tension, and
vice versa.
The tension is too low if the stage drops by itself of focus is quickly lost
after adjustment with the fine adjustment knob. In this case, turn the ring
Fig. 22 in the direction of the arrow to increase tension.

Pre-focusing Lever
(Fig. 23)
} The pre-focusing lever ensures that the objective does not come in contact
with the specimen and simplifies focusing.
After focusing on the specimen with the coarse adjustment knob, turn this
lever @ in the direction of the arrow and lock; the upper limit on coarse
adjustment movement is set at the locked position.
After changing a specimen, approximate refocusing is easily accomplis-
hed by rotating the coarse adjustment knob to reach the pre-focused
position. After this, all you have to do is make fine adjustments with the
fine adjustment knob.
} Stage movement with the fine adjustment knob is not locked.
When the pre-focusing lever is locked, a coarse movement stro-
ke is reduced due to the microscope’s mechanism, causing the
stage not to be able to be lowered to the lower limit. To lower
the stage to the lower limit, release the pre-focusing lever.
