electromagnetic interference (EMI). Do not install the system in the vicinity of any
device that emits EMI.
• Do not use in the presence of flammable products.
• This motor is equipped with an electronic circuit to limit file separation. Nevertheless,
files may still separate due to incorrectly set torque or speed, or the use of fatigued files.
• Dental low voltage electric motors should not be used in the presence of a flammable
anesthetic gas mixed with air, oxygen, or nitrous oxide.
(Note: nitrous oxide by itself is not a flammable anesthetic gas.)
• The contra-angle must be steam sterilized prior to initial use and between patients to
prevent cross contamination. After sterilization, make sure the contra-angle attachment
has reached a temperature below 40 °C (104 °F) before use (see chapter H:
Cleaning,disinfection and sterilization).
Precaution
• This product is intended for use by dental professionals only.
• The appliance must only be used with the manufacturer's original accessories.
• Use the Dentsply charging stand for this product. Never use any other battery
chargers.
• Use only 16:1 ratio contra-angle attachments with this product. Contra-angle
attachments with gear ratios other than 16:1 will cause errors in the display
readings and torque limitation system.
• If the motor stops or runs too fast, discontinue use and call for assistance.
• Do not introduce any oil into the micromotor.
• The system functions normally in the environment where the temperature is at
10 - 40 ˚C (50 - 104 ˚F), humidity at 10 - 85% RH, atmospheric pressure at
500-1060hPa, and with no moisture condensation in the Handpiece or Charging
Stand. Any use outside these limits may cause malfunction.

• Do not use a bent, damaged, deformed or non-ISO-conforming file. Using such a file
may result in injury.
• Check the product before use by turning it on, paying attention to looseness,
vibration, noise and temperature (heat generation). If any abnormal condition is
found, no matter how slight, immediately stop use and contact your distributor.
• For your own safety, please wear personal protective equipment (Gloves,
glasses, mask).
• Always clean the shank of the file or the Gates Glidden to be installed. Allowing
dirt to enter the chuck could cause loss of concentricity and deterioration of
chucking force.
• Before changing the head or file, turn off the power to the motor handpiece.
Changing with the power kept on may cause unintended rotation by accidental
touch of the Forward or Reverse buttons.
• Pay attention to the direction of the battery connector when installing. Forcible
installation in the wrong direction may cause damage and fluid leakage due to
a short circuit.
• Do not use the handpiece unless the rotary file is secure within the contra-angle
attachment.
• Never mount an attachment to the handpiece body while it is running.
• Never press the push-button on the contra-angle attachment while the handpiece
is running.
• The “torque limit” feature is intended as an aid to help reduce breakage of rotary
files. It is not a substitute for professional judgment and clinical good practice.

user instructions. Use only approved parts and supplies. Failure to do so will void the
warranty, can degrade product performance, and may lead to unsafe operation.
• If you observe water in the charging stand, disconnect the electrical power. The
charging stand has been designed to allow water and debris to drain from the
charging contact area, however, debris could potentially plug the drain, increasing risk
of electrical shock. Disconnect electrical power prior to cleaning debris from the drain.
• This product is designed for use with a rechargeable 1500mAH Lithium-Ion battery.
Any other battery type may cause degraded system performance.
• Other than battery replacement, there are no user-serviceable items in the
X –SMART
™Easy handpiece body or charging stand; opening either of these
can result in unsafe operation.
• The handpiece body is not waterproof. Do not immerse the handpiece body in
water or a chemical solution. Do not spray liquids onto this device – wipe only.
(See section H: Cleaning, disinfection and sterilization)
• Fully-charged rechargeable batteries generally discharge gradually over time even
though the motor handpiece is not used. It is recommended to place the handpiece
in the charger when not in use.
