• Always insert burs and points all the way in and give them a light tug to make sure they will not come out.
Otherwise, a bur or point could come out and injure the patient or be swallowed.
• Wait for the handpiece to completely stop rotating before inserting or removing a bur or point.
3. Inserting and Removing Burs and Points
• Protect your fi ngers from being cut by wearing gloves whenever you put in or take out a bur or point.

Hold the push button down fi rmly and pull the bur or point straight out.
Operation 2/2
Take out the bur or point and disconnect the handpiece from the motor.
* Refer to the user manual for the motor.
* It may be hard to remove a bur or point if it is left in the handpiece.
4. After Use
5. Cleaning
If a medical agent being used for the treatment has adhered to
the handpiece, wash it off in running water.
Do not perform ultra sonic cleaning.
Wipe the handpiece with a piece of gauze that has been dampened with
Ethanol for Disinfection (ethanol 70 vol% to 80 vol%) and wrung out
thoroughly. Clean the end of the light guide if the light seems to be dim.
(only model with a light)
Do not use anything except ethanol. Do not use too much ethanol; it could seep inside and damage the handpiece.
Rotation and spray delivery will be impaired if debris gets inside the water or air lines.
Do not immerse the handpiece in or wipe it with any of the following: functional water (acidic electrolyzed water,
strong alkaline solution, and ozone water), medical agents (glutaral, etc.), or any other special types of water or
commercial cleaning liquids. Such liquids may result in metal corrosion and adhesion of the residual medical agent to
the handpiece.
6. Disinfection
7. Lubrication
Lubricate with the LS Spray (sold separately) or MORITA MULTI SPRAY (sold separately) before autoclav-
ing and after morning and afternoon treatment sessions.
Insert the nozzle into the connection end of the handpiece,
hold it fi rmly and then spray for 2 seconds.
Put the spray nozzle on the spray can.
Failure to lubricate the handpiece will result in a malfunction.
Never use any spray other than the LS SPRAY or MORITA MULTI SPRAY.
The head could get quite cold if the spray is applied for more than 5 seconds. In this case, wait awhile
before operating the handpiece; otherwise the bearings could be damaged.
Always use the spray can in an upright position. Use only the special spray nozzle provided.
8. Removing Excess Oil
Connect the handpiece to the motor, point the head
down, and run the motor for about 30 seconds. Use a
piece of gauze to wipe off any oil that gets on the outside
of the handpiece
.
• After lubricating the handpiece, do not fail to remove excess oil. The motor could malfunc-
tion if any oil get inside of it. Also excess oil inside the handpiece could cause it to overheat.
When wiping off excess oil from the head, make sure that you do not touch the push button while
the handpiece is running. Doing so will result in wear to the cap and cartridge, making insertion and
removal of the bur diffi cult.
10. Troubleshooting
◆
Cannot insert burs or points
Take the handpiece off the motor and step on the foot pedal. Does water come out of the motor joint?
If water does not come out
Refer to the accompany user manual for the motor.
If water comes out
Check the o-ring on the motor joint. Replace it if it is worn or damaged and
coat it with oil. If the o-ring is OK, clean out the air and water holes on the
handpiece. Also take out the water fi lter and clean it. (only model with a
light : See diagram at right.) If the spray still does not work, have the hand-
piece repaired.
◆
Poor water delivery
◆
Poor rotation
Lubricate the handpiece, and then use a new bur or point to check if the problem has been resolved.
If this does not resolve the problem, have the handpiece repaired.
Before inspecting or adjusting the handpiece, make sure the main power switch is turned on and that the main air and
water valves are open. If the handpiece does not work properly even after inspection and adjustment, contact your local
dealer or J. MORITA OFFICE and have it repaired.
Clean drilling and polishing debris off the head with a brush and
running water.
Clean the spray hole with the spray hole wire provided.
After cleaning, use the syringe or an air blow gun to get rid of any
moisture left inside the handpiece.

After autoclaving, store the handpiece in a dry environment.
* Autoclaving and drying temperatures must not 135° C
(+275° F)
* Minimum drying time after sterilization: 10 minutes.

Operating Precautions
•
Always use a handpiece holder when washing the handpiece, making sure to rinse the inside of the handpiece
thoroughly.
•
For details on handling medical agents or adjusting their concentration, refer to the user manual for the washing device.
•
After washing is complete, check to see if the handpiece, including its inside, is completely dry. If any water
remains inside the handpiece, expel it with an air gun or another such tool. Failure to do so could result in the
remaining water coming out during use and cause poor lubrication or sterilization.
•
Always lubricate the handpiece after washing.
Always use a handpiece holder when washing the handpiece; otherwise any medical agent remains inside the
handpiece, it may corrode or clog the air or water pipe, resulting in a malfunction of the handpiece.
Inappropriate cleaning methods and solutions will damage the handpiece.
Do not clean the handpiece using strong acidic or alkaline solutions that could cause the metal to corrode.
Any moisture left inside the handpiece could result in the remaining water coming out during use and cause
corrosion, or poor lubrication and sterilization.
Do not leave a handpiece inside the high-temperature washer-disinfector.
• Do not point the spray can at anyone.
• Do not use the spray in a closed space without proper ventilation. Open windows and turn on
exhaust fans to make sure the room is well ventilated.
• Do not get the spray in your eyes. If you accidentally get it in your eyes, wash your eyes with
plenty of water and see a doctor.
• Do not get the spray on your skin. If it gets on your skin, wash it off with soap and water.
• If used in a sink or other enclosed space, a fl ammable mist could permeate the air; keep the area
free of open fl ames or other ignition sources.
Using an air blow gun, blow the handpiece connection for
20 to 30 seconds to get rid of any moisture left inside the
handpiece. Wipe the excess oil from the handpiece with a
gauze.
You can use MORITA's threeway syringe instead of an air
blow gun.
(In this case, attach the air nozzle to the tip of the threeway
syringe. The air nozzle comes with a micromotor or its
optional accessory.)
Recommended Temperature and Time:
In a sterilization pouch, minimum 6 minutes at +134°C (+273.2°F) or
minimum 60 minutes at +121°C (+249.8°F)
Do not sterilize the handpiece by any method other than autoclaving.
Remove the bur or point before autoclaving.
Failure to clean and lubricate the handpiece before autoclaving will lead to a malfunction of the handpiece.
The sterilization and drying temperatures must not 135°C (+275°F). A drying temperature in excess of
+135°C (+275°F) will result in contamination of the handpiece or cause it to malfunction.
When autoclaving the handpiece, do not let it come into contact with the heat source or the body of the autoclave to
avoid damage to the O-rings or other parts due to the high temperature.
Do not leave the handpiece in the autoclave.
Make sure the motor is properly connected to its tube. Remove the handpiece from the motor and step on the foot
control. Does the motor run?
If motor runs
Make sure the handpiece is connected to the motor correctly, then step on the foot control to see the bur runs. If
the bur does not run, have the handpiece repaired.
If motor does not run
Refer to the accompany user manual for the motor.
