FOCUS TENSION ADJUSTMENT:
The focus tension adjustment is easily adjusted by using the C-Wrench
(Part MT202). This wrench fits the tension collar found on the focusing
control spindle, between the adjustment knob and body of the
microscope. A clockwise turn of this collar moves it toward the upright
support and increases tension, while a counter-clockwise turn moves
the collar toward the knob and decreases tension.
