EVIS EXERA II TJF TYPE Q180V OPERATION MANUAL
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 the angulation control
knobs is 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, and return them to their respective neutral
positions. Confirm that the bending section angulates smoothly and
correctly, that maximum angulation can be achieved, and that the bending
section returns to its neutral position.
3.
When the UP/DOWN and RIGHT/LEFT angulation control knobs are turned
to their respective neutral positions as shown in Figure 3.4, confirm that the
bending section returns smoothly to an approximately straight condition.
