authorized by the manufacturer.

Standards and Procedures for the Disposal of Medical Devices

If there is a possibility that a medical device is contaminated, the dentist or doctor responsible for the patient's treatment must
confirm that it is uncontaminated, and must then have it disposed of by a healthcare facility or an agent licensed and qualified to
handle standard industrial waste and industrial waste requiring special treatment.

Maintenance and Inspection

* This instrument should be inspected every 3 months.
* Maintenance and inspection are generally considered to be the duty and obligation of the user, but if, for some reason, the user
is unable to carry out these duties, the user may rely on a qualified medical device serviceman. Contact your local dealer or J.
MORITA OFFICE for details. Inspect the following items: 1. Micromotor connection. 2. Bur and file insertion. 3. Handpiece rota-
tion. 4. Overheating. 5. Canal length meter display.
* For repairs, contact your local dealer or J. MORITA OFFICE.

Service and Contacts

The TORQTECH may be repaired and serviced by:
• The technicians of J. MORITA's subsidiaries all over the world.
Technicians employed by authorized J. MORITA dealers and specially trained by J. MORITA.
•
Independent technicians specially trained and authorized by J. MORITA.
•
For repairs or other types of service, contact your local dealer or J. MORITA OFFICE.

Prohibitions

: This indicates when not to use the device.
• Do not use the TORQTECH on patients who have implanted pacemakers or defibrillators.
• No modification of the TORQTECH is allowed.
• Do not perform maintenance while using the TORQTECH for treatment.
• Do not use the wireless transmission devices listed below in the examination area:
1. Cell phone terminals.
2. Wireless transmitting devices such as ham radios, walkie-talkies, and transceivers.
3. Personal Handy-phone System (PHS)
4. Routers for intra-building paging systems, wireless LAN, cordless analogue telephones, and other electric
wireless devices.

Warnings and Cautions

• The maximum input rotation for the CA-10RC-ENDO (speed reduction model for endodontics) is 20,000
rpm (2,000 rpm as file rotation). Do not input more than 20,000 rpm. Otherwise, this may result in over-
heating the head or the handpiece could be damaged.
• The head heats up if it runs at 2,000 rpm. Do not use it for more than 3 minutes at 2,000 rpm.
• Do not force the handpiece inside the oral cavity if the mouth is not open wide enough. It could contact
the opposing tooth, and inadvertently press the push button. Running the handpiece with the push button
held down could cause the push button to overheat and damage the opposing tooth. It could also burn
the patient or the dentist and the bur or file could come out.
• After maintenance, do not cover the handpiece with gauze when operating it to remove excess oil. If the
push button is inadvertently held down, the head could overheat or the handpiece could break down.
• In cases of tooth extractions, split teeth, endodontic treatment etc. or incision or open wounds in soft
tissue, the tip air must be turned off to avoid causing a subcutaneous emphysema due to emitted air from
the handpiece.
• The CA-10RC-ENDO must not be connected to or used in combination with any other apparatus or system.
It must not be used as an integral component of any other apparatus or system.
File Usage
(Nickel-Titanium files are easily broken. Keep the following points in mind to minimize file breakage.)
• Never use excessive force to insert the file.
• Never use excessive force to advance the file down the canal. (Using excessive force could break a Ni-Ti
file.)
• All files eventually break due to metal fatigue. Replace old files in a timely manner.
• Never use stretched, deformed or bent files.
• Do not get chemical solutions such as FC or hypo-chlorite on the head or contrary electrode. These could
cause inflammation.
Using the Endodontic Contra Angles with Units and Micromotors that Have Canal
Measurement Capability
• Before use, read all relevant instructions that come with the dental treatment unit thoroughly.
• Before use, touch the file in the CA-10RC-ENDO with the contrary electrode on the probe cord connected to
the dental treatment unit, and make sure all the bars in the meter for the measurement display on the chair
light up. If they do not, do not use the handpiece. Something is probably wrong with the display.
• Some files do not work with the built-in electrode inside the CA-10RC-ENDO. Be sure to test the hand-
piece as described above.
• The built-in electrode will work for only some types of files.
It will not work if there is no conductivity between the file and shank or if the shank does not conduct
electricity. Do not use these types of files.
• If a file will not work with the built-in electrode inside the CA-10RC-ENDO, you can install a separate
external file electrode that will work.
• Canal measurement cannot be performed with contra angles and micromotors that do not have this
capability. For canal measurement, make sure the dental treatment unit, micromotor and CA-10RC-ENDO
all have this capability.
• Accurate measurement cannot be performed if the built-in or external file electrode is worn out.
Replace the electrode with a new one.
• If the dental treatment unit's canal length indicator measurement readings are unstable, stop using the
handpiece immediately and replace the built-in electrode or external file electrode.
• When using canal measurement functions, do not operate this handpiece faster than 1,200 rpm. The
meter may be somewhat erratic.
• If a chemical solution such as sodium hypochlorite gets on the head, wash it off immediately. Otherwise,
metal contacts could be corroded and prevent accurate measurement of the canal.
• Always use a rubber dam for preparing root canals.
• Wear safety glasses or similar eye protection to prevent eye injury from cutting debris.
• Run the handpiece outside the oral cavity before using it and make sure the bur or file does not wobble
and that it runs at the correct speed and in the right direction.
• If a bur or file comes out during use, stop using the handpiece immediately and have the handpiece
repaired.
• Do not press the push button until the handpiece comes to a complete stop. Otherwise, the inside of the
button could wear out and make it hard to insert and remove burs or files.
• If the handpiece makes abnormal noise, vibrates too much, or overheats, take out the bur and replace it
with a new one. If the same problem persists, have the handpiece repaired.
• Follow all recommendations of the bur manufacturer concerning bur rotation speed and direction.
Wait for the handpiece to come to a complete stop before inserting or removing burs or files.
Wait for the bur or file to stop rotating before taking it out of the oral cavity.
Remove burs and files before returning the handpiece to its holder in the dental treatment unit;
otherwise there is a risk of injury or damage.

have canal measurement capability of the CA-10RC-ENDO.
• Never use the following types of burs and files; they could come out and injure the patient or be swallowed:
Those which do not conform to ISO standards. Those with scratched or bent heads or shanks. Those which are rusty,
chipped or broken. Those which have been modified or altered such as those having shortened shanks.
• Even new burs and files are sometimes poorly balanced; if a bur or file makes a loud, metallic noise
during rotation, stop using it.
• Spray and tip air are not emitted.
Always use burs and files with clean shanks.
Always carefully remove all cleaning fluids before inserting a bur into the chuck; some cleaning fluids are corrosive
and can ruin the chuck.
* If a dirty bur or file or ones with cleaning fluid have been inserted by mistake, contact your local dealer or J. MORITA
OFFICE. to have the handpiece inspected.
