Carefully inspect the distal end of the endoscope, especially around the
ultrasonic transducer. Confirm that there are no flaws, cracks, scratches, or
any other irregularities.
Inspection of the bending mechanism
Perform the following inspection while the bending section is straight.
 Inspection for smooth operation
1.
Turn the UP/DOWN angulation control lever slowly in each direction until it
stops. Confirm that the bending section angulates smoothly and correctly
and that maximum angulation can be achieved.
2.
Turn the UP/DOWN angulation control lever slowly to its neutral position.
Confirm that the bending section returns smoothly to an approximately
straight condition(see Figure 3.3).

If the movement of the angulation control lever is 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 become impossible to
straighten the bending section during an examination.
