WARNING

WARNING • TO PREVENT ELECTRIC SHOCK Do not touch the handpiece backend electrical connections. • If you feel any abnormality such as vibration, heat generation, abnormal noise, etc., prior or during the use, stop using it immediately. • This product is Medical Electrical equipment Electromagetic compatible (EMC) as described in the accompanying documentation. • Portable and mobile RF communications equipment can affect Electrical Medical equipment. Do not use RF equipment in close proximity to the product. • USE ONLY NSK genuine tips when using NSK Varios Ultrasonic Scaler (Varios 170 or Varios 170 LUX) problems such as damage, failure and accident of Handpieces resulting from use of Non-NSK Tips are not included in the warranty. The following are the possible failure that could happen when using the Non-NSK Tips; · Vibration failure caused by using non conforming screws. · Patients accidental ingestion of broken tips. · Damage of thread ridge of handpiece. • You must use the tip within the power range described on the Tip-Power Guide. If you use it out of the power range, the tip might break or damage an operative site. 1

WARNING • When operating the product always consider the safety of the patient. • Use by medical professional, such as doctor or dental hygienist, is intended. • Check the vibration outside the patient’s oral cavity before use. If any abnormalities are found, stop using immediately and contact dealer. • Do not drop, hit, or subject to excessive shock to the module. • To prevent possible tooth plane damage and handpiece overheating, Always use with sufficient water. • Do not sterilize by ultraviolet light. Handpiece could discolor. • Sterilize the Tip, Handpiece, and Tip Wrench by autoclaving. Wipe the Handpiece Cord including the cover. • Sterilize autoclavable products before their first use. • If chemical, solvent or antiseptic solution is deposited on this product, immediately wipe it away. Discoloration or deformation may occur if left. • Do not disassemble or alter the Module and handpiece. • Keep away from patients with cardiac pacemakers. • Keep away from explosive substances and flammable materials. Do not use for patients anesthetized under laughter gas. (Nitrous Oxide) • This product needs special precautions regarding EMC and needs to be installed and put into service according to the EMC information. • The use of ACCESSORIES, transducers and cables other than those specified, with the exception of transducers and cables sold by the manufacturer of this product as replacement parts for internal components, may result in increased EMISSIONS or decreased IMMUNITY of this product. • If any water drops remain on the handpiece after autoclaving, wipe them off. Staining may result if left. • There is the judgment that applies this product to a patient in the user side. • This product should not be used adjacent to or stacked with other equipment and that if adjacent or stacked use is necessary, this product should be observed to verify normal operation in the configuration in which it will be used. • Do not apply excessive power to the Tip. It may damage the teeth because of the ultrasonic vibration.

CAUTION • Read this Operation Manual before use to fully understand the product functions and file for future reference. • During operation, high frequency oscillations in the handpiece and handpiece cord may affect computer and LAN Noise may be heard during operation near a radio receiver. • Users are responsible for operational control, maintenance and inspection. • Clean/sterilize the product immediately after using it. Then store it. Leaving it non-sterile might lead to failure. • When you have not used the product for long time and use it again, check the operation before use. • Eye damage may result if the LED is stared directly into, Do not look into or turn it to the eyes of the patient. • No special training is required for this device. • Applied parts for patient and/or operator are/is Tip and handpiece. • Surface temperature of Tip shall be more than 50 degree without using a tap water. To avoid this event, be sure to use a tap water. * EMISSION refers to unwanted electromagnetic energy generated by equipments. IMMUNITY refers to the ability of an equipment to withstand in the presence of electromagnetic interference.

* Operation Principle A sinusoidal electrical signal, at ultrasonic frequency ( f > 20kHz ), is delivered by the generator. This signal is applied to the ‘piezoelectric ceramic’ located inside the transducer. Piezoelectric ceramic converts this signal into mechanical vibrations. These vibrations are at the same ultrasonic frequency as the electrical signal. The mechanical vibrations are propagated towards the distal end of the transducer. The “TIP” insert, which is attached at the distal end of the transducer, vibrates at ultrasonic frequencies and makes it possible to achieve the aimed purpose.

Caution for Tip Usage • Check the Tip before use. (Flush, Damage, Bending or Rust) • Do not exceed Maximum Power Level for Tip. Damage to tooth structure and Tip may result. • Do not hit ceramic prosthesis with Tip during scaling. Tip Damage may result. • Do not hit metal or prosthetic crown except for removing them. Tip could break and fall into mouth. • Do not hit gingival, mucosa and/or skin. It could cause damage and/or burn injury. • Do not sharpen and/or bend the Tip. Tip may damage and not generate enough vibration during scaling. • During cutting, Tip will gradually wear away, as the Tip wears the stroke will get smaller and decrease cutting efficiency when level drops too far, change the Tip.(Tip card check) • DO ENSURE when securing Tip to use the Tip Wrench as supplied, inefficient cutting will result. • DO ENSURE before attaching Tip, Cleanliness of the Tip Screw, inefficient cutting will result. • To avid personal injury DO ENSURE Tip is removed prior to disconnecting the handpiece. • If you feel the Tip is not vibrating, remove it from an operative site, and press the Foot Control of Unit Chair again. If this does not improve the condition, Ensure the Tip is secure, turn the power off and restart it. • When mounting the Tip, always use groves and Tip Wrench as supplied. • Ensure that water volume of Unit Chair must be “0”, when you use Tip which does not appear of water. • Tip Wrench is consumable For reliable operation replace annually.

G4

The end of the Tip is thin and for supragingival fine scaling and interdental scaling. The round cross-section allows tooth surfaces to be finished without causing damage.

Apply the top of the Tip on the tooth plane and move it sideways finely in the same way as G8 Tip. (Fig.4)

Fig.4

G8

Removal of supragingival and interdental calculus. This Tip can be used in all quadrants and is very useful for the removal of hard calculus.

Apply the top of the Tip on the tooth plane and move it sideways finely along the neck of tooth. (Fig.5)

Fig.5

G16

Removal of supra and subgingival calculus. It provides easy access to interdental spaces and narrow pockets.

Insert the top of the Tip into the periodontal pocket and move it slowly. The top of the Tip is sharp so that it could remove tartar on long coroner and retracted gingival. (Fig.6) Clean periodontal pocket at low power.

Fig.6

CAUTION Tip is article of consumption. We recommend periodical replacement. About time of replacement, check the Tip Card.

5. Provided Scaler Tips

WARNING Do not connect the supplied G16 Tip to a handpiece other than a Varios2 handpiece (VA2-LUX-HP / VA2-HP). Doing so may cause fracturing of the Tip or scratches on the surface of the dentition, prosthesis, etc. due to an increase in vibration amplitude.

Fig.7

How to use the Tip Card 1) Place the neck of the Tip in the cut out. 2) Check wear of the Tip. 3) See the green, yellow and red line to check wear of the Tip. *See below what each color means. At NSK we recommend to replace a Tip when the Tip meets the yellow line (wear of 1mm) to guarantee safe and effective use. Tip Card

Green: No wear - Tip is OK Tip replacement is not necessary.

Yellow: Wear of 1mm - Tip is showing some wear Tip replacement is recommended.

Red: Wear of 2mm - Tip is badly worn Tip replacement is necessary.

Fig.8

CAUTION Tips are consumables. The efficiency of dental scaling decreases approximately 25% when the top of the Tip wears 1 mm and approximately 50% when it wears 2 mm. In addition, the vibration condition changes owing to the wear, which may damage a patient’s tooth surface. Check the Tip wear condition with the Tip Card periodically, and replace the Tip with a new one in good time.
