Chapter 1. Overview 1.1 Operating Principle This device is an unit that consists of a main body, BLDC (brushless DC) motor, and foot pedal switch for driving and operating a handpiece for dental implant procedures, to be used in dentistry in the field of implant surgery. The main body of this device is powered by an external power supply that converts alternating current to direct current, which turns the BLDC motor; the rotation power of which combines with the handpiece to perform the dental implant procedure. The main body of the implant unit can be adjusted in terms of its torque, rotation speed, water injection volume, and rotational direction. The BLDC motor can be operated using the foot pedal switch. 1.2 Purpose of Use This is an engine used to power handpieces used for implants when performing dental implant procedures. 1.3 Users Only qualified dentists may use this device in a professional environment.. 1.4 Indications of Use 1) Where there is an absence of gum or teeth caused by cavities, gum disease, accidents or tumors. 2) Where enamel ablation is not recommended so as to protect the adjacent natural teeth. 3) Where the patient does not want denture treatment. 4) Where the patient wants to replace partial or full dentures that were previously used with a fixed-type dental prosthesis. 5) Where the patient wants full dentures to be replaced with some partial dentures and some fixed-type. 6) Where the patient requires implant support in relation to the lower dentures to maintain the full denture and also improve its function. 1.5 Checklist Prior to Use 1) Be sure to read the user manual prior to use. 2) Only to be used by a professional in a professional environment.. 3) Not to be used for anything other than its intended use.

Chapter 2. Safety (Warnings and Cautions) 2.1 Risks 1) If the cause of malfunction is unknown or if it cannot easily be resolved, please contact your dealer or your nearest BA repair centre. 2) If the display shows incorrect information, please contact your dealer or your nearest BA repair centre immediately. 3) Do not let the patients come into contact with the signal input piece, the signal output piece or other connecting pieces. 2.2 Notice 1) This product was designed to be used in implant procedures. The device should only be used in accordance with its intended usage and method. 2) The safety of the patient comes first and foremost. Be sure to pay sufficientattention when using the device. 3) Carefully study the user manual prior to use. Please familiarise yourself with the function of each part before using. 4) The main body and foot pedal switch of the implant unit cannot be cleaned in an autoclave. If the main body becomes contaminated, disconnect the power and clean with a clean, damp cloth, then wipe away the moisture with a dry cloth. 5) Prior to plugging in the device, check to confirm that the input voltage matches that of the device. 6) Any used water injection tube should be disposed of as medical waste. 2

2.3 Caution 1) Never attempt to disassemble or modify the device. Once the device is disassembled,you will no longer be entitled to after sales service from the manufacturer. 2) Never add oil to the inside of the BLDC motor. This can cause the bearings to malfunction and get hot. 3) Do not use thinner, benzene or any other solvents to clean. 4) Use only products and supplies that are prescribed by the specifications of the manufacturer. 5) If the power cord or plug socket is broken or damaged, do not use the deviceand inquire with the manufacturer. This could pose a risk of electric shock or fire. 6) When removing the power cord from the socket, be sure to pull the plug head, and do not do this with wet hands. Do not use the device with the power plug loosely connected. This could pose a risk of electric shock or fire. 7) Do not install near a heat source, and do not place near lit candles or cigarettes. This could pose a risk of fire. 8) Determine if there are any elderly, sick, injured, disabled persons, pregnant women or children near where the device is installed, and keep a close eye on such persons. Do not leave children alone with the device. 9) Ensure that the main body of the implant engine and the foot pedal do not come in contact with water, saline solution or other contaminants. If the device is not operating properly, or contaminants have entered the product, do not operate the device under any circumstances and inquire with the manufacturer instead. 10) Please use the device in accordance with the use stated in this user manual and refrain from using the device for any other purpose than that recommended by the manufacturer. The manufacturer will not be held liable for any accidents caused by a disregard for the instructions in the manual. 11) The external equipment for connecting the signal input piece, signal output piece or other connecting pieces must meet the IEC publication standards. 2.4 Warning 1) Prior to or during use, if you notice any abnormal symptoms including vibration, heat or abnormal noise, discontinue any use immediately and inspect the device. 2) Always use earthed socket for power supply. 3) With regard to tools used for implant procedure, please maintain the speed recommended by the manufacturer. Exceeding the recommended speed carried the risk of an accident.

Electromagnetic Environment Guidance Portable and mobile RF communications equipment should be used no closer to any part of the product, including cables, than the recommended separation distance calculated from the equiation applicable to the frequency of the transmitter. Recommended separation distance : d = 1.2√P d = 1.2√P for 80MHz to 800MHZ d = 2.3√P for 800 MHz to 2.5 GHz where P is the maximum output power rating of the transmitter in Watt (W) according to the transmitter manufacturer and d is the re-commended separation distance in meters (m) Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey(a), should be less than the compliance level(b) in each frequency range Interference may occur in the vicinity of equipment marked with the symbol described lateral.

Note 1: At 80 MHz and 800 MHz, the higher frequency range applies. Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, people and animals. (a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered, if the measured field strength in the location in which the product is used exceeds the applicable RF compliance level above, the product should be observed, additional measures may be necessary, such as reorienting or relocating the product. (b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m. 10.3 Recommended Separation Distances between portable and mobile HFcommunications equipment and the product The product is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the product can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the product – according on output power and frequency of the communications equipment – as recommended in the following table. Separation distance according to the frequency of transmitter in meter (m) Rated maximum output power of transmitter in watts (W) 150 kHz to 80 MHz d = 1.2√P 80 MHz to 800 MHz d = 1.2√P 800 MHz to 2.5 GHz d = 2.3√P 0.01 0.23 0.12 0.12 0.01 0.73 0.38 0.38 0.1 2.3 1.2 1.2 10 7.3 3.8 3.8 100 23 12 12 For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer. Note 1: At 80 MHz and 800MHz, the higher frequency range applies. Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, people and animals. 92
