Important Information — Please Read
Before Use
Intended Use
This instrument has been designed to be used with Light Sources,
Documentation Equipment, Endo-Therapy Accessories, Eletctrosurgical Unit
and other ancillary equipment for endoscopic applications within the lower
digestive tract including rectum and sigmoid colon.
Do not use this instrument for any purposes other than its intended use.
Applicability of Endoscopy and Endoscopic Treatment
If there is an official standard on the applicability of endoscopy and endoscopic
treatment that is defined by the hospital’s administration or other official
institutions such as academic societies on endoscopy, follow that standard.
Before starting endoscopy and endoscopic treatment, thoroughly evaluate its
properties, purposes, effects, and possible risk (their natures, extent and
probability). Perform endoscopy and endoscopic treatment only when its
potential benefits are greater than its risks.
Fully explain to the patient the potential benefits and risks of the endoscopy and
endoscopic treatment as well as any examination/treatment methods that can be
performed in its place, and perform the endoscopy and endoscopic treatment
only after obtaining the consent of the patient.
Even after starting the endoscopy and endoscopic treatment, continue to
evaluate the potential benefits and risks, and immediately stop the
endoscopy/treatment and take proper measures if the risks to the patient
become greater than the potential benefits.

OSF-3 OPERATION MANUAL
Instruction Manual
This instruction manual contains essential information on using this instrument
safely and effectively. Before use, thoroughly review this manual and the
manuals of all equipment, which will be used during the procedure and use the
instruments as instructed. Note that the complete instruction manual set for this
Endoscope consists of this manual and the “OLYMPUS OSF-3 ENDOSCOPE
REPROCESSING MANUAL” which also accompanied the Endoscope at
shipment.
Keep this and all related instruction manuals in a safe, accessible location.
If you have any questions or comments about any information in this manual,
please contact Olympus.
User Qualifications
The operator of this instrument must be a physician or medical personnel under
the supervision of a physician and must have received sufficient training in
clinical endoscopic technique. This manual, therefore, does not explain or
discuss clinical endoscopic procedures.
Instrument Compatibility
Refer to the “System Chart” in the Appendix to confirm that this instrument is
compatible with the ancillary equipment being used. Using incompatible
equipment can result in patient injury or equipment damage.
Reprocessing and Storage
This instrument was not disinfected or sterilized before shipment. Before using
this instrument for the first time, reprocess it according to the instruction in the
endoscope’s companion manual, the “OLYMPUS OSF-3 ENDOSCOPE
REPROCESSING MANUAL”.
After using this instrument, reprocess and store it according to the instructions in
the endoscope’s companion manual, the “OLYMPUS OSF-3 ENDOSCOPE
REPROCESSING MANUAL”. Improper and/or incomplete reprocessing or
storage can present an infection control risk, cause equipment damage or
reduce performance.

6
Important Information — Please Read Before Use
OSF-3 OPERATION MANUAL
• Do not strike, bend, hit, pull, twist, or drop the endoscope’s
distal end, insertion tube, bending section, control section,
universal cord, or endoscope connector of the endoscope
with excessive force. The endoscope may be damaged and
could cause patient injury, burns, bleeding and/or
perforations. It could also cause parts of the endoscope to fall
off inside the patient.
• Never perform angulation control forcibly or abruptly. Never
forcefully pull, twist or rotate the angulated bending section.
Patient injury, bleeding and/or perforation can result. It may
also become impossible to straighten the bending section
during an examination.
• Never perform angulation control, air feed control, suction
control or insertion/withdrawal of the endoscope’s Insertion
Tube without viewing the endoscopic image. Patient injury
can result.
• Do not operate the Bending Section, feed air or apply
suction, insert or withdraw the endoscope Insertion Tube
while the image remains frozen. This could result in patient
injury.
• Do not touch the Light Guide immediately after removing it
from the Light Source because it is extremely hot.
• Do not pull the Universal Cord. The Endoscope Light Guide
Connector will be pulled out from the output socket of the
Light Source and the endoscopic image will not be visible.
• Do not coil the Insertion Tube and Universal Cord with a
diameter less of than 12 cm. Equipment damage can result.
• Do not apply shock to the Distal End of the Insertion Tube,
particularly the Objective Lens surface of the Distal End.
Vision abnormalities may result.
• Do not twist or bend the Bending Section by hands.
Equipment damage may result.
• Do not squeeze the Bending Section forcefully. The covering
of the Bending Section may stretch or break and cause water
leaks.
• Do not hit or bend the Electrical Contacts on the Endoscope
Light Guide Connector. The connection to the Light Source
may be impaired and faulty contact can result.

OSF-3 OPERATION MANUAL
Details on clinical endoscopic technique are the responsibility of trained
specialists. Patient safety in endoscopic examinations and endoscopic treatment
can be ensured through appropriate handling by the physician and the medical
facility. Examples of inappropriate handling are given below.
• Over-insufflating the lumen may cause patient pain and/or perforation.
• Using improperly reprocessed or stored instruments may cause patient
cross-contamination and infection.
• Applying prolonged suction with the distal tip in contact with the mucosal
surface may cause bleeding or suction lesions.
• Retroflexing the endoscope within the esophagus, colon, or duodenal
bulb may cause mucosal trauma or impaction of the endoscope.
• Inserting and using Endo-Therapy Accessories without a clear
endoscopic view may cause burns or perforation.
• Patient injury may be caused by: inserting or withdrawing the
endoscope, feeding air or applying suction without a clear endoscopic
view; withdrawing the endoscope with the angulation controls locked;
forcefully pulling, twisting or rotating the angulated Bending Section.
