1 Inspect the control section, and endoscope connector for excessive scratching,
deformation, loose parts, or other irregularities.
2 Inspect the boot and the insertion section near the boot for bends, twists, or other
irregularities.
3 Inspect the external surface of the entire insertion section, including the bending
section and the distal end for dents, bulges, swelling, scratches, peeling of coating,
holes, sagging, transformation, bends, adhesion of foreign bodies, missing parts,
protruding objects, or other irregularities.
4 Holding the control section with one hand,
carefully run your other hand back and forth
over the entire length of the insertion section.
Confirm that no objects or metallic wire
protrude from the insertion section. Also,
confirm that the insertion tube is not abnormally
rigid.
