4-2 Adjusting the tension of the 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 b on the
tension adjustment ring a 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 a in the
arrow direction to increase the tension of the coarse focusing knob.
