2. Insert the biopsy forceps into the inlet seal (OF- B190). When the cups are first passed through the
inlet seal, temporary resistance will be encountered.
3. Hold the shaft at approximately 5 cm from the inlet seal and slowly advance the biopsy forceps, and
check that the tip exits the distal tip of the endoscope. In addition, check that no foreign materials were
pushed out of the instrument channel by the biopsy forceps.

4. Check that the biopsy forceps can be smoothly withdrawn from the inlet seal.
Inspection of the water jet feeding function
Warning
Use sterile water for inspection of the water jet feeding function. Failure to do so may pose a risk
of infection.
1. To use the irrigation pump, prepare to feed sterile water by following the instructions for use for the
irrigation pump.
2. Check the entire surface of the irrigation tube (OF - B113) for abnormalities such as bending / breakage /
looseness of the connector, cut /chip of the O - ring, buckling /deterioration / hardening of the tube, and/
or broken luer.
3. Open the water jet connector cap (OF- B118), connect the irrigation tube (OF- B113) to the water jet
check valve adapter (OE - C12) until it clicks into position.
Note
Do not use the irrigation tube (OF - B113) if you have any difficulty in attaching it, or if you do not
feel it clicking into place when attaching it to the endoscope. The use of damaged luer connector
may result in water leakage from the connected part or tube disconnection.
