8. Operation
Right-/Left-hand Operation
The coaxial pinion can be attached to either
side of the stage. (Also see Assembly, p. 20). To
change the side, follow these steps:
• Loosen the lock screw (48.5) at the bottom
left-hand side of the stage. The necessary
tool is attached to the bottom of the stage on
the right-hand side.
!
Caution:
The condenser must be lowered!
• Slide the stage all the way back.
• Release the screw (50.6) on the coaxial pinion
and pull the pinion out.
• Place the fine focus wheel on the side to
which you intend to mount the coaxial pinion.
The wheel is held in place magnetically. En-
sure that the button snaps into place. Attach
the other focus knob on the opposite side.
• Fasten the coaxial pinion to the other side of
the stage by retightening the appropriate
screw.
• Return the stage to the starting position and
retighten the lock screw. After installation of
the stage control, move object guide all the
way to the left side of the instrument. Keep
turning when guide has reached the end of
travel until a click noise is heard.
• Readjust the condenser.

8.3 Focusing
Coarse and Fine Focusing
Coarse and fine focusing wheels are located on
either side of the stand (Fig. 50 and 51).
The special design of the flat fine focus wheel
(Fig. 51.3) allows users to enclose the coaxial
pinion in their hands while operating the fine fo-
cus with one finger. The flat wheel should there-
fore be mounted on the appropriate side. See
right-/left-hand operation of the stage.
Height Adjustment of the Focusing Wheels
• Defocus the image by moving the stage down
with a full turn of the coarse focus wheel
(50.2, 51.2).
