8. Operation
Right-/Left-hand Operation
The coaxial pinion can be attached to either side
of the stage (also see Assembly, p. 16f). To
change the side, follow these steps:
• Loosen the lockscrew (37.5) 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 (37.6) on the coaxial pinion
and pull the pinion out.
• Place the fine focus wheel (37.3) on the side to
which you intend to mount the coaxial pinion.
The wheel is held in place magnetically.
Ensure 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 lockscrew.

8.3 Focusing

Coarse and Fine Focusing
Coarse and fine focusing wheels are located on
either side of the stand (Fig. 37 and 39).
The special form of the flat fine focus wheel
(Fig. 37.3) lets users enclose the coaxial pinion
in their hands while operating the fine focus
with one finger. The flat wheel should therefore
be mounted onto 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
(37.2, 39.1).
• Grasp the right-hand and left-hand focus
knobs at the same time and press the knobs
gently upward or downward into the desired
position.
• Refocus the image.
