<Ultrasonic Mode and Powder Mode>
• Do not handle the power cord with wet hands. Wet hand contact with electricity may result in an electric shock.
• Keep away from explosive substances and flammable materials.
• If the product overheats or smells of burning, immediately turn off the power and disconnect the main power cord. Contact your Authorized
NSK Dealer.
• TO PREVENT ELECTRIC SHOCK, use a main electrical outlet that is earthed.
• Do not operate close to patients with cardiac pacemakers as there is a danger that it may affect the pacemaker.
• The system functions normally in the environment where the temperature is at 0 - 40°C (32 - 104°F), humidity at 35 - 75% RH, and no
moisture condensation in the Control Unit. Using in conditions outside these limits may cause malfunction.
• Be careful not to get water or liquid disinfectant in the Control Unit. This could cause short circuits and lead to fire and/or electric shock.
• Repeatedly turning the Main Power Switch ON and OFF may blow a fuse.
• If water droplets, chemicals, solvents or antiseptic solution come into contact with the Control Unit, Handpiece, Handpiece Cord, Handpiece
Hose, etc., wipe them off immediately. Failure to do so may result in discoloration or deformation.
• Connect to a public water system that provides drinkable water at a water pressure between 0.1 and 0.3MPa. Using with an incorrect water
pressure may result in insufficient water supply, inoperability, or malfunction.
• Use a water softener, etc. to lower the hardness of the water, because using water with a high degree of hardness may cause mineral or
limescale deposits in the water circuit, which can lead to problems such as insufficient water levels, operation problems, or breakdown.
When doing so, use a Water Tube with a Water Filter to prevent device breakdown due to the foreign material in tap water, and refer to
"10-3 Changing the Water Filter" to replace the Water Filter as required.
• Do not sterilize using ultraviolet light. Doing so may result in discoloration of the Handpiece.
• Hold the plug when pulling out the Handpiece Cord or Handpiece Hose. Pulling the Cord or Hose may cause disconnection or damage.
<Ultrasonic Mode>
• Always use the water supply. Insufficient water supply results in overheating, which may damage the surface of the patient's tooth.
• Do not allow the patient or assistant to look directly into the LED of the Handpiece or Handpiece Cord. Doing so may damage eyesight.
<Powder Mode>
• Do not use on the following patients.
– Those with medical complications or allergies
– Those who have pre existing conditions (Eg Cardiac, Pulmonary, Renal disturbance or High blood pressure)
– Those with respiratory diseases.
– Those with pathologically deep periodontal pockets (6mm or more) or mucosal lesions. Prolonged application of the spray to soft tissue or
salivary glands may cause powder air to enter soft tissue or salivary glands, resulting in emphysema.
– Those with severe digestive ulcers.
– Those with renal dysfunction.
– Those with lung or cardiac disturbance or ventilatory impairment.
– Those with an artificial heart valve or artificial joint
– Those with allergies. Depending on the patient's constitution, allergy symptoms or stomatitis may be caused in very rare cases. If such
symptoms are detected, stop using the product immediately and seek medical attention.
• During use, both the operator and the assistant should always wear protective glasses and protective face masks. Also, continuously
vacuum and collect ejected powder during use. If any powder gets into the eyes, eyes wash out immediately with copious amount of water
and consult an ophthalmologist.
• Set the supply air pressure to 0.55 - 0.75MPa and use clean, dry air. Using with the incorrect pressure may result in insufficient spray
pressure (power), inoperability or malfunction.
<Prophy Mode>
• Do not spray directly onto the cement in the root canal, decalcified enamel, filling, margin of a prosthesis or filling.
