1. Adjusting focus tension.
Tension comes pre-adjusted by the manufacturer. The optimum tension point is that which
allows as smooth a movement possible of the focus knobs, but does not allow the stage to slide
down by itself.
The adjustment collar (Fig. 2) is situated between the focussing knob (12) and the head.(4).
Loosen the screw situated in the hole on the collar, with the 2mm hexagonal key.
a. To increase tension turn collar clockwise, to decrease tension turn anti-clockwise.
b. Retighten the hexagonal screw.
