Burs
Using dirty shanks will cause the chuck to lose its gripping power and accelerate wear on the burs or points.
Some bur detergents contain components that cause metals to rust. Be sure to wash away the bur detergent before
inserting the bur into the chuck. If any bur detergent enters the chuck, the cartridge and chuck will malfunction.
Diamond points bend easily. Even a new bur or point may not have good rotational balance and they may make an
extremely loud metallic sound when rotating. In such cases, stop using the bur as it is defective.
*1 If any bur detergent, dust, or other foreign matter enters the chuck, contact your local dealer or J. MORITA OFFICE to request
an inspection.
*2 Use miniature burs or short-shanked burs for PAR-4HUMX-O. Do not use miniature burs or short-shanked burs for any other
type of handpiece.
• Never use the types of burs or points described below. Using such burs or points is extremely dangerous as
they may become detached and cause injury to the patient's oral cavity or be swallowed by the patient.
Burs or points that do not conform to ISO standards; that have any grooves, scratched or damaged blades or
shanks; that are deformed, bent, rusty, chipped or broken; or that have been modifi ed (such as short-shanked burs).
CAUTION
• When using welded or blazed burs, ensure that the bur tip does not wobble.
• Be sure to follow the requirements regarding the usable bur length and the shank length. Using non-support-
ed burs is dangerous as they may become detached and cause a malfunction.

Warnings and Cautions

• In cases of tooth extractions, split teeth, endodontic treatment etc. or incision or open wounds in soft tis-
sue, care must be taken that air emitted from the handpiece does not cause a subcutaneous emphysema.
• If the bur or point becomes detached while you are drilling a tooth, stop using the instrument immediately.
• When removing tooth decay, never apply force in a direction that could result in the bur or point becoming
detached (scooping up) or apply excessive force.
• Always spray water while using the handpiece to avoid injury to the dental pulp.
• Wait until the bur stops rotating before placing the handpiece inside the patient's oral cavity or removing it.
1 • Avoid operating the handpiece in the following ways as doing so could cause the head, push button and cap
to heat up, resulting in burns to the patient.
• Holding down the push button while the handpiece is in operation.
• Operating the handpiece with the push button pressing against the teeth opposite the working area
when the patient's mouth is not fully open.
9
• Operating the handpiece when abnormal rotation or vibration is suspected.
10.6 CAUTION
• Always wear personal protective equipment (PPE), such as safety glasses, gloves, etc. when using this
7 .5 and over
handpiece.
20 and under
• Be sure to remove the bur or point when storing the handpiece in the dental treatment unit. Storing the
handpiece with the bur or point attached could result in physical injury or property damage.
Crown removal and similar operations produce considerable vibration, which can result in the bur getting stuck in the
*1
handpiece. Avoid this by stopping at regular intervals to remove and reinsert the bur, rather than drilling continuously.
1.

Before Use

* The handpiece is not sterilized before shipping. It must be autoclaved before it is used for the fi rst time.
Pre-use inspection: Check for the following before using the handpiece.
• The cap and cap screw have been tightened properly.
• There are no gaps between the connection parts of the cap, head, and body
and no rattling can be heard.
• There are no cracks, chips, protrusions or dents on the light guide.
There are no rust, scratches or dirt.
•
• The handpiece rotates smoothly and does not slow down, there is no abnormal
vibration or noise, the head, push button or cap does not heat up.
The spray has a fi ne, misty quality and is emitted from all of the spray holes.
•
If an abnormality is found, refrain from using the handpiece and have it profession-
ally repaired.
• If the cap or the cap screw are loose or if they are damaged or worn, the cap or the cartridge could fl y off in-
side the oral cavity and cause an injury.
2.

Attaching the Handpiece

* Refer to the user manual for the CP4-(W-)O, CP4-(W-)LD couplings.
Handpiece Connection
• Before connecting the handpiece, make sure the lamp cover and connection end are not loose, worn, or
damaged.
• Before using the handpiece, always try operating it outside the oral cavity fi rst to ensure that it is securely
attached to the tube or the coupling. If it is not securely attached, the tube could become detached and
cause physical injury.
Handle the handpiece carefully. Do not drop it, bang it against the dental treatment unit, etc. Doing so could result
in abnormal rotation or, in the event of damage to the light guide, reduced illumination.
Ensure that the handpiece connection or coupling is free of dust and other foreign matter (fi ber such as cotton, O-
ring pieces, etc.). Failure to do so could result in damage to the handpiece.

Take care to insert the bur straight
limitation
all the way in.
Refer to instructions for Do not force the bur in with-
use out holding down the push
button. Doing so will damage
the bur and the chuck.
• Insert the burs and points as far as they will go into the chuck.
• Before using the handpiece, try operating it outside the oral cavity fi rst to ensure that the bur or point does
not wobble, there is no abnormal vibration or noise, and no heat is generated.
• If the bur or point is not completely inserted or an abnormal bur or point is used, the bur or point may be-
come detached and be swallowed by or cause physical harm to the patient.
• Wait until rotation stops completely before inserting or removing bur or point.
CAUTION
(Ethanol disinfectable)
• Exercise caution when inserting or removing the bur or point so as not to injure your fi ngers.
• If you notice any abnormal noise or vibration during use, replace the bur or point with a new one and then
try operating the handpiece to check if the problem has been resolved.
If the bur gets stuck in the handpiece, do not forcibly remove it using pliers or other tools; have it repaired instead.
(Ethanol disinfectable) If excessive force is applied, the chuck may become damaged.
Make sure cap is not loose.
Cap
Make sure the cap
screw is in place.
Insert
Insert the bur completely.
Hold down the
push button.
Hold down the push button fi rmly, push the bur all the way in, and then re-
lease the push button.
* It is easier to press the push button if you support the body of the hand-
piece with your forefi nger positioned at a point between the head and the
body.
