1 Intended Use
The Leakage Tester is designed to check watertightness of Olympus endoscopes in conjunction with Olympus Light
Source or Maintenance Unit (MU-1).
The meaning(s) of the symbol(s) shown on the back cover of this instruction manual are as follows:
Authorized representative in the European Community
3 Signal Words
The following signal words are used throughout this manual:
Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It
may also be used to alert against unsafe practices or potential equipment damage.
Medical Devices Directive
This device complies with the
requirements of Directive 93/42/EEC
concerning medical devices.
Classification: Class I
2.84 × 104 Pa or less
1. Inspect that the Connector is not markedly deformed.
2. Inspect that the Coiled Tube is not cracked.
3. Inspect that the Connector Cap is not deformed, nor is it wet inside.
Water drops inside the Connector Cap may enter the endoscope through the Venting Connector of the
endoscope’s Light Guide Connector Section or Water-resistant Cap and damage the internal construction.
Remove them by shaking the Connector Cap several times.
4. Inspect that the Guide Pin inside the Connector Cap is not missing, broken, or deformed.
Refer to the instructions manual of the Light Sources, Maintenance Unit and Endoscopes.
Connecting to the Light Source (or Maintenance Unit)
1. Turn the power switch ON.
2. When using the Light Source, set the air feeding pressure to “HIGH” or “3” using the air regulator switch.
• When using a Light Source other than OES/EVIS, turn ON the switch and ignition switch (if applicable).
• Adjust the Light Source brightness to the minimum light output.
Insert the Leakage Tester’s Connector fully into the output socket, then make sure that the air pump’s operating
noise is heard.
When using a Light Source other than OES/EVIS, make sure that air is emitted through the air pipe inside the
Connecting to the Endoscope
1. Lightly depress the pin inside the Connector Cap and ensure that air is being emitted through the Coiled Tube.
• Repeat Section 6.1 above, if air is not emitted.
Make sure that no water drop is present inside the Connector Cap.
3. Check that the Venting Connector of the endoscope’s Light Guide Connector Section or Water-resistant Cap is
free from water drops.
Wipe dry the Venting Connector with a piece of gauze to prevent the endoscope internal construction from
Place the Connector Cap over the Venting Connector, aligning the Pin on the Connector with the keyway on the
Connector Cap. Depress and rotate the Connector Cap clockwise (approximately 90) until no further rotation is
5. Pull the Connector Cap outward and make sure that it does not come off.
At this point, note an expansion of the Bending Section’s covering due to increased internal pressure.
When attaching the Leakage Tester, always connect it to the Light Source first. Reversing Sections 6.1 and
6.2 (i.e. connecting to the endoscope first) will damage the endoscope.
Connect it to the Venting Connector of the endoscope’s Light Guide Connector Section or Water-resistant
Cap before putting the endoscope in water; otherwise water will leak into the endoscope.
1. Immerse entire endoscope in water.
2. Observe the endoscope carefully for about 1 minute. If no bubbling is observed from the endoscope, the
endoscope is watertight. Proceed to Section 6.4.
Some initial bubbling may be observed due to air trapped in crevices on the endoscope’s outer surface. This
A thorough observation may be achieved by turning over the endoscope in water.
Continuous bubbling from a given area indicates a leak. DO NOT USE ENDOSCOPE.
3. If continuous bubbling in observed from a given area, this indicates a leak.
Remove the endoscope from the water immediately.
Turn OFF Light Source and disconnect the Leakage Tester from the Light Source.
Wait approximately 30 seconds (or until the covering of the Bending Section returns to its normal shape);
then disconnect the opposite end of Leakage Tester from the endoscope.
DO NOT USE THE ENDOSCOPE. And send it to Olympus.
Disconnecting the Leakage Tester
Remove the entire endoscope from the water and turn OFF the Light Source (or Maintenance Unit).
Disconnect the Leakage Tester from the Light Source (or Maintenance Unit).
Wait approximately 30 seconds (or until the covering of the Bending Section returns to its normal shape).
Disconnect the Leakage Tester from the Venting Connector on the endoscope’s Light Guide Connector Section or
Water-resistant Cap by depressing and rotating it counterclockwise.
Do not detach the Leakage Tester before the endoscope has been removed from the water.
When detaching the Leakage Tester, always disconnect it from the Light Source first. Failure to follow this
exact procedure will not allow the instrument to depressurize and damage will result.
Thoroughly dry the Leakage Tester.
7 Maintenance and Storage
1. Clean the Leakage Tester with a piece of gauze moistened with 70% ethyl or isopropyl alcohol.
2. Remove any moisture from the Connector Cap.
Endoscope and Light Source (or Maintenance Unit)
Clean and store each instrument according to its instruction manual.
Attach/detach in the air
(and not under water).
Make sure pump noise is heard.
Make sure air is emitted
through coiled tube.
The covering of the
Thoroughly wipe dry.
Slight expansion of the covering is OK.
Never disconnect leakage tester
while fiberscope is under water.
