Connect air scaler to the handpiece hose.
In case the supply air pressure at the connection (where the scaler is
connected to the handpiece hose) is set at the recommended
0.28MPa(2.9kgf/cm
2
), the air scaler is readily usable.
ŘRead these cautions carefully to correctly follow the intended use.
ŘSafety instructions are intended to avoid potential hazards that could result in personal injuries or damages to the device. Safety instructions
are classified as follows in accordance with the seriousness of the risk.
CAUTIONS IN HANDLING
ŘDo not exceed the recommended air pressure at the back end of the scaler. Excessive air pressure might cause the scaler tip to
accidentally break while in use.
ŘThe oscillation of the tip could exceed 200 Pm amplitude at the recommended air pressure. Caution is requested not to harm the patient.
ŘDo not use a tip on which rust is found. It may break while in use at where rust grew.
WARNING
ŘPlace the most priority of the patient’s safety.
ŘFor professional use only. Do not make incorrect use of the handpiece.
ŘDo not exceed 0.28 MPa (2.9kgf/cm
2
) when setting the air pressure at the dental unit.
ŘIf any abnormalities are found in use, stop using immediately and contact your dealer.
ŘDo not disassemble, nor alter the air scaler.
ŘDo not drop, hit, or subject to excessive shock.
ŘCheck the vibration, noise and overheating outside of the patient’s mouth before initial use. If any abnormalities are found in use, stop using
immediately and contact your dealer.
ŘBe sure to stop the air supply, and replace the tip or the coupling joint.
ŘWatch out the sharp point of the tip.
ŘDo not use a spray lubricant. Limited air discharge orifice size of the scaler forces the propellant pressure to build up inside, and the scaler
may fly off.
ŘDo not clean or wipe the scaler with highly oxidized or acid water or sterilizing solution.
CAUTION
1. Specifications
2. Installation and Supply Air Pressure
Moisture and debris in drive air may cause the air scaler to malfunction. It is important to drain the air compressor on a regular basis, even
though an air filter or air drying device is provided in the air line.
3. Use Dry, Clean Air
Three types of scaler tips as shown in Fig.2 are supplied as accessory items to the scaler.
Typical applications are explained below:
Type S1
…
Universal Type (Reorder number: Z252411)
Curved surfaces, exposed anterior root surfaces, posterior teeth with excessive
lingual tipping, etc.
Type S2
…
Sickle Type (Reorder number: Z252413)
Mandibular anterior teeth, lingual surfaces, hard thick-walled calculus firmly
adhered to a tooth, etc.
Type S3
…
Perio Type (Reorder number: Z252412)
Subgingival and supragingival calculus, tar-like deposit, etc.
To avoid rusting, dry it by air syringe, after removing from the scaler body, immediately after use.
The irrigant port and the threads need to be kept dry.
4. Scaler Tips
Air Scaler
WARNING
ŘSet the supply air pressure at 0.28MPa (2.9kgf/cm
2
) at the connection where the scaler is connected to the handpiece hose, as
shown by the arrow in Fig.1.
ŘHigher air pressure may cause higher tip oscillation, which could damage the tooth surface and may cause pain to the patient. It also
may shoten the tip life and premature failure or breakage of the tip.
ŘThe amplitude may exceed 200Pm, even at the recommended air pressure, care should be exercised not to harm the patient.
CAUTION
The proper air pressure for the air scaler is approximately 0.03MPa higher than the proper air pressure for an air turbine handpiece
because of difference internal structure.
CAUTION
Tips may rust. Poor drying could cause the tips to rust, which may result in premature failure and injury.
