Adjusting tension of coarse focusing knob
The tension of the coarse focusing knob can
be adjusted. Insert the tip of a large flat-blade
screwdriver into the groove [a] on the tension
adjustment ring [b] and rotate the ring.
Rotating the coarse focusing knob in the
arrow direction shown in the picture increases
the tension and rotating it in the opposite
direction decreases the tension respectively.
Never apply the excessive force for rotating the tension adjustment ring [a] in the arrow
direction shown in the picture. The ring may be damaged.
If the revolving nosepiece descends by its own weight or the focus obtained with the fine focusing
knob [c] is lost soon, the tension is set too loose. In this case, turn the tension adjustment ring [b]
in the arrow direction to increase the tension of the coarse focusing knob.
