Examples of inappropriate handling
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 described below;
•Over-insufflating the lumen may cause patient pain, injury, bleeding
and/or perforation.
•Applying suction with the distal end in prolonged contact with the
mucosal surface, with higher suction pressure than required or with
prolonged suction time may cause bleeding and/or lesions.
•The endoscope has not been designed for use in retroflexed
observation in parts of the body other than the stomach. Performing
retroflexed observation in a narrow lumen may make it impossible to
straighten and/or withdraw the endoscope. Retroflexed observation in
parts of the body other than the stomach should be performed only
when the usefulness of doing so is determined to be greater than the
risk that is posed to the patient.
•Inserting, withdrawing and using endo-therapy accessories without a
clear endoscopic image may cause patient injury, burns, bleeding and/or
perforation.
•Inserting or withdrawing the endoscope, feeding air, applying suction or
operating the bending section without a clear endoscopic image may
cause patient injury, bleeding and/or perforation.

2.4Attaching the chain for water-resistant cap
(MAJ-1119)
•Do not lift the endoscope by the chain for water-resistant cap.
Otherwise, operator and/or patient injury can result, or the
endoscope and/or water-resistant cap may be damaged
when the fitting part comes off the S-cord connector mount or
the chain connector of the GIF-N260 and GIF-XP260.
•Only connect the fitting to the S-cord connector mount or the
chain connector of the GIF-N260 and GIF-XP260.
Connecting the fitting to the suction connector may impair the
connection of the suction tube to the suction connector. It
may also cause the suction tube to become disconnected
from the endoscope and allow patient debris to spray.
•The chain for water-resistant cap and water-resistant cap
itself cannot be ultrasonically cleaned; doing so could
damage them. The water-resistant cap with the chain can
only be ultrasonically cleaned if connected to endoscopes
that are being cleaned in an endoscope reprocessor (such as
OER, OER-A) with an ultrasonic cleaning phase.
•When attaching the water-resistant cap to the electrical
connector, do not pinch the chain for water-resistant cap
between the electrical connector of the endoscope and the
water-resistant cap. Otherwise, equipment damage may
result.
•The chain for water-resistant cap and water-resistant cap
cannot be Ethylene oxide gas sterilized; doing so may
damage them. If the water-resistant cap is connected to the
endoscope by the chain, be sure to remove the chain and the
water-resistant cap from the endoscope before Ethylene
oxide gas sterilization.
•The chain for water-resistant cap and water-resistant cap
cannot be steam sterilized (autoclaved); doing so can
damage them severely.

3.2Inspection of the endoscope
Clean and disinfect or sterilize the endoscope as described in the
“REPROCESSING MANUAL” whose cover lists the model of your endoscope.
Then remove the water-resistant cap from the endoscope connector.
Inspection of the endoscope
1.
Inspect the control section and the endoscope connector for excessive
scratching, deformation, loose parts or other irregularities.
2. Inspect the boot and the insertion tube near the boot for bends, twists or
other irregularities.
3. Inspect the external surface of the entire insertion tube including the
bending section and the distal end for dents, bulges, swelling, scratching,
holes, sagging, transformation, bends, adhesion of foreign bodies, dropout
of parts, any protruding objects or other irregularities.
4. Holding the insertion tube gently with one hand, carefully run your fingertips
over the entire length of the insertion tube in both directions (see Figure
3.2). Confirm that no objects or metallic wire protrude from the insertion
tube. Also confirm that the insertion tube is not abnormally rigid.
Figure 3.2
5. Using both hands, bend the insertion tube of the endoscope into a
semicircle. Then, moving your hands as shown by the arrows in Figure 3.3,
confirm that the entire insertion tube can be smoothly bent to form a
semicircle and that the insertion tube is pliable. When inspecting
endoscopes with flexibility adjustment, perform the test with the insertion
tube at both its most-flexible and most-rigid settings (for endoscopes with
flexibility adjustment only).

Figure 3.3
6. Gently hold the midpoint of the bending section and a point 20 cm from the
distal end. Push and pull gently to confirm that the junction between the
bending section and the insertion tube is not loose.
7. Inspect the objective lens and light guide lens at the distal end of the
endoscope’s insertion tube for scratching, cracks, stains or other
irregularities.
8. Inspect the air/water nozzle at the distal end of the endoscope’s insertion
tube for abnormal swelling, bulges, dents or other irregularities.
Inspection of the flexibility adjustment mechanism (for
endoscopes with flexibility adjustment only)
Confirm that the marks (“z”, “1”, “2”, “3”) on the flexibility adjustment ring
1.
and the “” mark at the bottom of the grip section are clearly visible (see
Figure 3.4).
Figure 3.4
EVIS LUCERA GIF/CF/PCF TYPE 260 Series OPERATION MANUAL

Chapter 3 Preparation and Inspection
2. Confirm that the flexibility adjustment ring can be turned smoothly when the
insertion tube is straight.
3. Set the insertion tube to the most-flexible and most-rigid conditions,
respectively. In each case, hold the marks of 30 and 50 cm of the insertion
tube with two hands, and bend it gently as shown in Figure 3.5. Confirm that
the actual flexibility changes according to the flexibility adjustment setting.
Do not use the endoscope if the marking are not clearly
visible. If the operator is uncertain of the flexibility of the
endoscope, insertion and manipulation of the endoscope
may cause patient pain and/or injury.
If the insertion tube is coiled into a too small diameter, the
flexibility adjustment ring may not operate smoothly. This
does not indicate a malfunction.

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 their angulation control
knobs are 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 (except GIF-N260).
•If the movement of the UP/DOWN angulation lock and its
angulation control knob are 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 (for GIF-N260 only).
Chapter 3 Preparation and Inspection
Inspection for smooth operation
1. Confirm that both the UP/DOWN and RIGHT/LEFT angulation locks move
all the way in the “F” direction (the GIF-N260 has only the UP/DOWN
angulation lock).
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 (the GIF-N260 has only the UP/DOWN angulation knob). Confirm
that the bending section angulates smoothly and correctly, that maximum
angulation can be achieved and that the bending section returns to its
respective neutral positions.

3.3Preparation and inspection of accessories
Clean and disinfect or sterilize the air/water valve, suction valve, biopsy valve
and auxiliary water tube as described in the endoscope’s companion
reprocessing manual, the “REPROCESSING MANUAL” whose cover lists the
model of your endoscope.
Inspection of the air/water and suction valves
Confirm that the top hole of the air/water valve is not blocked
(see Figure 3.8). If the hole is blocked, air is fed continuously
and patient pain, bleeding and/or perforation can result.
1. Confirm that the holes of the valves are not blocked (see Figures 3.8 and
3.9).
2. Confirm that the valves are not deformed or cracked (see Figures 3.8 and

The air/water and suction valves are consumables. If the
inspection of the air/water or suction valve reveals any
irregularities, use new valves.
Inspection of the biopsy valve
The biopsy valve is a consumable that should be inspected
before each use. Replace it with a new one if irregularities
are observed during the following inspection. An irregular,
abnormal or damaged valve can reduce the efficacy of the
endoscope’s suction system, and may leak or spray patient
debris or fluids, posing an infection-control risk.

3.6Inspection of the endoscopic system
Inspection of the endoscopic image
Do not stare directly at the distal end of the endoscope while
the examination light is ON. Otherwise, eye injury may result.
1. Turn the video system center, light source, monitor, magnification controller
(for CF-H260AZL/I only) and endoscope position detecting unit (for
CF-Q260DL/I only) ON and inspect the WLI endoscopic image as described
in their respective instruction manuals.
2. Confirm that light is output from the endoscope’s distal end.
3. While observing the palm of your hand, confirm that the WLI endoscopic
image is free from noise, blur, fog or other irregularities.
4. Angulate the endoscope and confirm that the WLI endoscopic image does
not momentarily disappear or displays any other irregularities.
If the object cannot be seen clearly, wipe the objective lens
using a clean lint-free cloth moistened with 70% ethyl or
isopropyl alcohol.
Inspection of remote switch
All remote control switches should be checked to work
normally even when they are not expected for use. The
endoscopic image may freeze or other irregularities may
occur during examination and may cause patient injury,
bleeding and/or perforation.
Depress every remote control switch and confirm that the specified functions
work normally.
Inspection of the air feeding function
1.
Set the airflow regulator on the light source to “High”, as described in the
light source’s instruction manual.
2. Immerse the distal end of the insertion tube in sterile water to a depth of
10 cm and confirm that no air bubbles are emitted when the air/water valve
is not operated.
EVIS LUCERA GIF/CF/PCF TYPE 260 Series OPERATION MANUAL
69
Chapter 3 Preparation and Inspection
3. Cover the hole in the air/water valve with your finger and confirm that air
bubbles are continuously emitted from the air/water nozzle.
4. Uncover the hole in the air/water valve and confirm that no air bubbles are
emitted from the air/water nozzle.
If a stream of air bubbles is emitted from the air/water nozzle
even though the air/water valve is not being operated and the
distal end of the insertion tube is 10 cm or more below the
surface of the sterile water, there may be an irregularity in the
air feeding function. If the endoscope is used while air is
continuously fed, over-insufflation and patient injury may
result. If air bubbles are emitted from the air/water nozzle,
remove and reattach the air/water valve correctly, or replace
it with a new one. If this fails to stop air bubbles from being
emitted, do not use the endoscope, as there may be a
malfunction. Contact Olympus.
When the distal end of the insertion tube is immersed less
than 10 cm below the surface of the sterile water, a small
amount of air bubbles may be emitted from the air/water
nozzle even when the air/water valve is not operated. This
does not indicate a malfunction.
Inspection of the objective lens cleaning function
Use sterile water only. Non sterile water may cause patient
cross-contamination and/or infection.
•When the air/water valve is depressed for the first time, it
may take a few seconds before water is emitted.
•If the air/water valve returns to its original position slowly after
water feeding, remove the air/water valve and moisten the
seals with sterile water.
•During the inspection, place the distal end of the endoscope
in a beaker or other container so that the floor does not get
wet.
70
1. Keep the air/water valve’s hole covered with your finger and depress the
valve. Observe the endoscopic image and confirm that water flows on the
entire objective lens.
EVIS LUCERA GIF/CF/PCF TYPE 260 Series OPERATION MANUAL
2. Release the air/water valve. Observe the endoscopic image and confirm
that the emission of water stops and that the valve returns smoothly to its
original position.
3. While observing the endoscopic image, feed air after feeding water by
covering the hole in the air/water valve with your finger. Confirm that the
emitted air removes the remaining water from the objective lens and clears
the endoscopic image.
Inspection of the suction function
•If the suction valve does not operate smoothly, detach it and
reattach it, or replace it with a new one. If the endoscope is
used while the suction valve is not working properly, it may
be impossible to stop suction, which could cause patient
injury. If the reattached or replaced suction valve fails to
operate smoothly, the endoscope may be malfunctioning;
stop using it and contact Olympus.
Chapter 3 Preparation and Inspection
•If the biopsy valve leaks, replace it with a new one. A leaking
biopsy valve can reduce the efficacy of the endoscope’s
suction system, and may leak or spray patient debris or
fluids, posing an infection-control risk.
1. Place the container of sterile water and the endoscope on the same height.
For the inspection, adjust the suction pressure to the same level as it will be
during the procedure.
2. Immerse the distal end of the insertion tube in sterile water with the
endoscope’s instrument channel port at the same height as the water level
in the water container. Press the suction valve and confirm that water is
continuously aspirated into the suction bottle of the suction pump.
3. Release the suction valve. Confirm that suction stops and the valve returns
to its original position.
4. Depress the suction valve and aspirate water for one second. Then, release
the suction valve for one second. Repeat this several times and confirm that
no water leaks from the biopsy valve.
5. Remove the distal end of the endoscope from the water. Depress the
suction valve and aspirate air for a few seconds to remove any water from
the instrument and suction channels.

control function again.
Inspection of the auxiliary water feeding function (for
GIF-H260Z only)
•Use sterile water only. Non-sterile water may cause patient
cross-contamination and/or infection.
•Note that the luer port on the MAJ-855 includes a one-way
valve to prevent backflow – do not use the MAJ-855 without
the luer port in place, otherwise backflow of contaminated
material may occur and equipment damage or patient injury
may result.
1. Attach a syringe containing sterile water or the water tube from a water
pump to the luer port of the auxiliary water tube (see Figure 3.25). Feed
water and confirm that water is emitted from the auxiliary water channel at

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. It only describes basic operation and
precautions related to the operation of this instrument.
•Wear personal protective equipment to guard against
dangerous chemicals and potentially infectious material
during the procedure. Wear appropriate personal protective
equipment, such as eye wear, face mask, moisture-resistant
clothing and chemical-resistant gloves that fit properly and
are long enough so that your skin is not exposed.
Chapter 4 Operation
•The temperature of the distal end of the endoscope may
exceed 41°C and reach 50°C due to intense endoscopic
illumination. Surface temperatures over 41°C may cause
mucosal burns. Always use the minimum level of illumination,
minimum time and suitable distance necessary for adequate
viewing. Whenever possible, avoid close stationary viewing
and do not leave the distal end of the endoscope close to the
mucous membrane for a long time.
•Whenever possible, do not leave the endoscope illuminated
before and/or after an examination. Continued illumination
will cause the distal end of the endoscope to become hot and
could cause operator and/or patient burns.
•Turn the video system center ON to operate a light source’s
automatic brightness function. When the video system center
is OFF, it cannot operate the light source’s automatic
brightness function, and the light intensity is set to the
maximum level. In this case, the distal end of the endoscope
can become hot and could cause operator and/or patient
burns (when using the light source other than CLV-260SL,
CLV-260).

Chapter 4 Operation
•Never insert or withdraw the endoscope under any of the
following conditions. Otherwise, patient injury, bleeding
and/or perforation can result.
− While the endo-therapy accessory extends from the distal
end of the endoscope.
− While the bending section is locked in position.
− Insertion or withdrawal with excessive force, or forcible
insertion or withdrawal.
− While the image is magnified (when using the GIF-H260Z,
CF-H260AZL/I or using the image magnification function
of video system center CV-260SL, CV-260).
•Transnasal insertion is accompanied by the risk of
inflammation of the nasal cavity. If this happens, the nasal
passage will be constricted, making it more difficult to
withdraw the endoscope. In this case, do not use force to
withdraw the endoscope because patient injury such as
bleeding or perforation may result.
•Transnasal insertion is accompanied by the risk of bleeding
in the nasal cavity. Be sure to be prepared to deal with any
bleeding. When withdrawing the endoscope, observe the
inside of the nasal cavity to ensure that there is no bleeding.
Even when the endoscope has been withdrawn without
bleeding, do not allow the patient to blow his or her nose
strongly because this could cause it to start bleeding.
•Before transnasal insertion, apply the appropriate
pretreatment and lubrication to the patient to enlarge the
nasal cavity. Otherwise, operator and/or patient injury can
result or the endoscope could become lodged and be difficult
to withdraw. When applying a pretreatment agent through a
tube, insert the tube into the same path as the path planned
for the endoscope insertion. Otherwise, the treatment will
have no effect. The effects of the pretreatment agent and
lubricant will decrease the longer the procedure lasts. Apply

•The bending section will never bend to the RIGHT or LEFT
direction but to the UP or DOWN direction. To insert or
withdraw, operate the endoscope by considering the direction
in which the bending section is angulated. Never apply
excessive force to the RIGHT or LEFT direction when
inserting or withdrawing the endoscope. Patient injury,
bleeding and/or perforation can result (for GIF-N260 only).
•If any of the following phenomena occurs during an
examination, immediately stop the examination and withdraw
the endoscope from the patient as described in Section 5.2,
“Withdrawal of the endoscope with an abnormality” on
page 102.
− If any abnormality is suspected with the functionality of
the endoscope.
− If the endoscopic image on the monitor disappears or
freezes unexpectedly.
− If the angulation control knob is locked.
− If the angulation control mechanism is not functioning
properly.
− If the zoom malfunctions (when using the GIF-H260Z,
CF-H260AZL/I or using the image magnification function
of video system center CV-260SL, CV-260).
− If the flexibility adjustment ring becomes jammed (for
endoscopes with flexibility adjustment only).
Continued use of the endoscope under these conditions
could result in patient injury, bleeding and/or perforation.
•If an abnormal endoscopic image or function is observed, but
quickly corrects itself, the endoscope may have
malfunctioned. Continuous use of such an endoscope may
cause the abnormality to occur again, at which time it may
not return to the normal condition. In this case, stop the
examination immediately and slowly withdraw the endoscope
while viewing the endoscopic image. Otherwise, patient
injury, bleeding and/or perforation can result.
•Never perform flexibility adjustment while the endo-therapy
accessory extends from the distal end of the endoscope.
Patient injury, bleeding and/or perforation can result (for
endoscopes with flexibility adjustment only).

Chapter 4 Operation
•Regardless of the flexibility of the endoscope’s insertion tube,
it can cause patient injury, bleeding and/or perforation if it is
forcibly inserted, withdrawn and/or twisted with excessive
force. It is generally believed that an endoscope with a
more-rigid insertion tube is easier to manipulate in the
intestines if used properly. However, it should be noted that
such an endoscope, if used improperly, is more likely to
cause patient pain, injury, bleeding and/or perforation than an
endoscope with a more flexible insertion tube (for
endoscopes with flexibility adjustment only).
•The flexibility of the insertion tube of the CF-Q260AL/I can be
adjusted to less than, equal to or more than that of the
CF-240L/I. The range of the flexibility adjustment of the
CF-Q260AL/I is equal to that of the CF-240AL/I.
The flexibility of the insertion tube of the CF-Q260DL/I can be
adjusted to less than, equal to or more than that of the
CF-240L/I and CF-Q240L/I. The range of the flexibility
adjustment of the CF-Q260DL/I is equal to that of the
CF-240DL/I.
The flexibility of the insertion tube of the CF-H260AL/I and
CF-H260AZL/I can be adjusted to less than, equal to or more
than that of the CF-Q240L/I and CF-Q240ZL/I. The range of
the flexibility adjustment of the CF-H260AL/I and
CF-H260AZL/I is equal to the CF-Q240AL/I.
The flexibility of the insertion tube of the PCF-Q260AL/I can
be adjusted to less than, equal to or more than that of the
PCF-240L/I.
The insertion tube of the endoscope should be adjusted to
the appropriate flexibility for each case. Always confirm the
flexibility of the insertion tube by holding the insertion tube
with two hands before inserting it into the patient, and adjust
the flexibility as necessary according to the case, region and
patient’s condition during an examination. If you are unsure
of the appropriate flexibility of the insertion tube, set it to the
most-flexible condition. Continuing the examination while the
insertion tube is set to an inappropriate degree of flexibility
may cause patient pain, injury, bleeding and/or perforation
(for endoscopes with flexibility adjustment only).

observation modes. Therefore, do not perform an endoscopic
operation or treatment while switching the observation mode.
Otherwise, injury in the body cavity may result.

Chapter 4 Operation
•Set the brightness of the light source to the minimum level
necessary to perform the procedure safely. If the endoscope
is used for a prolonged period at or near maximum light
intensity, vapor may be observed in the endoscopic image.
This is caused by the evaporation of organic material (blood,
moisture in stool, etc.) due to heat generated by the light
guide near the light guide lens. If this vapor continues to
interfere with the examination, remove the endoscope, wipe
the distal end with a lint-free cloth moistened with 70% ethyl
or isopropyl alcohol, reinsert the endoscope and continue the
examination.
•The color tone and brightness of the NBI observation is
different from the WLI observation. Use the NBI observation
only when fully understanding the feature.
4.1Insertion
Holding and manipulating the endoscope
The control section of the endoscope is designed to be held in the left hand. The
air/water and suction valves can be operated using the left index finger. The
UP/DOWN angulation control knob and the zoom lever can be operated using
the left thumb. The right hand is free to manipulate the insertion tube and the
RIGHT/LEFT angulation control knob (see Figure 4.1, the GIF-N260 has only the
UP/DOWN angulation control knob).

Chapter 4 Operation
Insertion of the endoscope
•The distal end and insertion tube diameter of the GIF-XP260
is smaller than for other GIF models, but this does not mean
that its design assumes an insertion method other than
transoral insertion. Do not attempt transnasal insertion, as
this may cause injury, bleeding or perforation inside the nasal
cavity.
•The shape and size of the nasal cavity and its suitability for
transnasal insertion may vary from patient to patient. No
endoscope, including this one, can always be inserted
transnasally with all patients. Before proceeding, always be
sure to confirm that transnasal insertion is possible with the
patient by always considering both the size of the patient’s
nasal cavity as well as the size of the endoscope’s insertion
tube. Otherwise, operator and/or patient injury can result, or
the endoscope could become lodged and be difficult to
withdraw.
•Transnasal insertion of the endoscope should be performed
carefully. If resistance to insertion is felt, or the patient reports
