Inspection of the bending mechanisms
Perform the following inspections while the bending section is straight.
If the movement of the UP/DOWN angulation lock,
RIGHT/LEFT angulation lock and their angulation control
knobs are loose and/or not smooth, or the bending section
does not angulate smoothly, the bending mechanism may be
abnormal. In this case, do not use the endoscope because it
may be impossible to straighten the bending section during
an examination.
Inspection for smooth operation
1.
Confirm that both the UP/DOWN and RIGHT/LEFT angulation locks move
all the way in the “F
” direction.
2.
Turn the UP/DOWN and RIGHT/LEFT angulation control knobs slowly in
each direction until they stop. Confirm that the bending section angulates
smoothly and correctly and that maximum angulation can be achieved.
3.
Turn the UP/DOWN and RIGHT/LEFT angulation control knobs slowly to
their respective neutral positions as shown in Figure 3.6. Confirm that the
bending section returns smoothly to an approximately straight condition.
