Contra-angle Dental Handpieces Operation Manual

・An accidental symptom, such as subcutaneous emphysema may be developed in the use of this product for extraction of wisdom teeth. Do not direct air exhausted from the handpiece to the bleeding area (wound) or into periodontal pockets. ・Report all serious events related to the product immediately to the manufacturer and the responsible national authority. ・Do not apply excess pressure to the bur as it may break or bend and become difficult to remove. ・Always follow the instructions provided by the bur manufacturer regarding the bur usage and rotation speed, etc.

・This product is equipped with the Quick Stop Function, which means that when the air supply is stopped, the rotation stops in a shorter time than conventional handpieces. Also, when you turn the attached bur by hand, there will be resistance, but this is not a malfunction. ・This product has a structure that a small amount of air escapes from the joint with the coupling. If liquid such as lubricating oil remains inside the handpiece, the liquid may leak from the joint, but this is not a malfunction. (Z890L /Z990L / Z890KL / Z990KL / Z890SL / Z990SL) ・Substances which are carcinogenic, mutagenic or toxic to reproduction (‘CMR’), of category 1A or 1B, in accordance with Part 3 of Annex VI to Regulation (EC) No 1272/2008 of the European Parliament and of the Council, or substances having endocrine-disrupting properties for which there is scientific evidence of probable serious effects to human health and which are identified either in accordance with the procedure set out in Article 59 of Regulation (EC) No 1907/2006 of the European Parliament and of the Council or, once a delegated act has been adopted by the Commission pursuant to the first subparagraph of Article 5 of Regulation (EU) No 528/2012 of the European Parliament and the Council, in accordance with the criteria that are relevant to human health amongst the criteria established therein: lead (Pb), cobalt (Co). - This product can be safely used in the treatment of children, pregnant or breastfeeding women, or other patient groups considered particularly vulnerable to such substances.

Follow the specifications described in this operation manual as to supply pressure, the bur to be used, etc. Do not use air contaminated by dust, moisture or oil.

Sudden release of the handpiece may cause injury.

If blood or debris is stuck, wipe in and around the bur insertion hole with a cloth moistened with disinfectant solution until all residues are thoroughly removed. Residual blood or debris may enter the handpiece while changing burs, which could lead to higher risk of cross-contamination.

・To ensure cleaning and sterilization efficacy, use only the following procedures for reprocessing. ・Follow local rules, regulations, and guidelines regarding the reprocessing of devices. ・Immediately after a treatment (within 1 hour), perform maintenance and then store the handpiece. Failure to 3 / 12

properly maintain the handpiece may cause infection, product failure, overheating leading to burn injuries. ・If blood infiltrates inside a handpiece, an automatic handpiece cleaning and lubrication system may not totally clean the internal handpiece components and may lead to blood coagulation inside the handpiece. Coagulated blood may cause handpiece failure and overheating, causing burn injuries. To avoid the risk, NSK recommends to immediately lubricate those handpieces with PANA SPRAY Plus.

・Do not use the following fluids to wipe, immerse or clean the product; strong/super acid water, strong acid/alkaline chemicals, chlorine containing solutions, solvents such as benzine or thinner. ・After washing with washer-disinfector, prior to lubrication, dry the product until all internal moisture is completely removed. Remaining moisture inside the product could reduce the effect of lubrication and could cause corrosion inside of the product. ・Remove the handpiece from the washer-disinfector immediately after the cleaning, disinfecting, and drying cycle

is

complete (within 1 hour), otherwise it may cause corrosion. ・Do not use sprays other than NSK PANA SPRAY Plus. Using other sprays may cause handpiece overheating. ・Clean and lubricate the handpiece prior to sterilization. If blood remains on the internal surface, it may become clotted and cause product failure. ・Immediately after sterilization is complete (within 1 hour), remove the handpiece from the sterilizer. Failure to do so may cause corrosion. ・Do not perform steam sterilization on the product with other instruments even when it is in a pouch. This is to prevent possible discoloration and damage to the product from chemical residue on other instruments. ・Sterilization is not guaranteed after the sterilization retention period specified by the manufacturer and seller of the sterilization pouch has elapsed. If the sterilization retention period has elapsed, perform sterilization again with a new sterilization pouch. ・Do not use sterilization pouches containing water-soluble adhesive components such as PVA (polyvinyl alcohol). Adhesive components washed out during sterilization may enter the product, causing problems such as poor rotation, sticking and failure to operate correctly. ・Do not heat or cool the product too quickly. Rapid change in temperature could cause damage to the product. ・The product lifetime and product’ s ability to operate correctly are mainly determined by mechanical stresses during use and the chemical influences due to processing. If you detect any abnormality such as center run-out of bur, heat generation, vibration or noise, or if the exterior markings (serial number or model number) have become unreadable before or during use, stop using the product immediately and request your nearest NSK dealer, or one of the NSK branches for a periodic inspection. ・When the product has been reprocessed 250 times or has been in use for one year, it is recommended that a periodic inspection be performed by an authorized NSK service. ・Store the product in a well ventilated place out of direct sunlight and within the range of temperature, humidity and pressure specified in specifications.

If another cartridge is used NSK cannot guarantee performance and the handpiece warranty would become invalid.

・Replace the O-rings if water is present in the exhaust air line. This is an indication of possible water leakage within the coupling. ALWAYS change the complete set of O-rings. ・Do not force the new replacement O-ring with excessive pressure. ・When inserting new O-rings, make sure they are inserted in the correct grooves.

Make certain that the taper ring is firmly tightened. If the taper ring is loose water and air leakage could occur.
