14 10. Cautions 1) Caution for Installation, Adjustment and Maintenance Qualified Persons : Only qualified persons who have technical training and professional knowledge can handle X-ray tube assembly. Fragile Glass : X-ray tube is assembled with glass, therefore, it can be broken with the mechanical vibration or pulsed shock over 19.6m/(2G). Careful handling is required to treat or transport. Ground Terminal : X-ray tube assembly has ground terminal. Ground cable should be connected. High Voltage : All X-ray tubes operate at voltages high enough to kill through electric shock. Never touch the high voltage delivered plugs or terminals. When direct access to such parts is required, the primary circuit should be disabled and high voltage capacitors/cables discharged. High Voltage Plug : High voltage plug should be cleaned up and free from any physical damages. Silicon compound application is required for high voltage stability. Rotating Anode - Test rotation of the anode with the large focus filament at the preheat condition. At this time, do not supply the tube voltage. - When the hand switch READY button is pressed, the filament will become brighter and the anode target will start rotating. The anode for normal speed will reach the predetermined number of revolution in 0.4 to 1 sec., and it will continue rotation for some time after the stator drive input is cut off. The anode for high speed shall be automatically braked to reduce speed and continue coasting after the drive input to the stator is cut off. - Ensure that the anode target rotates in the proper direction. X-ray tube should always rotate counter-clockwise, viewing from the cathode side. Operation Atmosphere : X-ray tube assembly is not allowed to use in the atmosphere of flammable or corrosive gas. Protective Cover : X-ray tube assembly is not allowed to use without the protective cover Handling : Appropriate jigs or tools are required for tube installation to avoid physical damages. Returning Tube : X-ray tube assembly should be repacked with the original material when it is returned back for quality examination in our factory. Be careful to put the tube upside cathode. If the packaging is not proper, the tube may not be correctly examined. Page 14

15 2) Caution to interface with X-ray Generator Over Rating : X-ray tube assembly can be broken with applying just one over rated shot. Please read the specification sheets carefully and follow the instructions. Permanent Filtration : The total filtration and the distance between X-ray focal spot and human body are regulated legally. They should be complied with the regulation. Safety Thermal Switch : X-ray tube assembly has safety thermal switch to prohibit further input power when the tube housing reaches to the temperature of switch-open. The switch should be hooked up with the X-ray generator which control output power to X-ray tube assembly. The switch is not recommended connecting stator coil in series circuit. Even if the switch works, never turn the system power off. The cooling unit should be activated if used with the system. Safety Plate : The Safety Plate is mounted on anode housing wall. When external cover is removed, it is visibly recognized as labeled with label 8 in Caution Labels page. Followings are important notice of the Safety Plate: - Function : When housing inner pressure reaches to the working pressure of the Safety Plate, the Safety Plate collapses and vaporized oil and hot oil flow through the collapsed Safety Plate. The external cover can protect the initial impact of oil flow, however, it can not protect oil drop or oil leakage. - Caution : Never touch the Safety Plate or remove the label and the screws. Otherwise, it could cause collapse of Safety Plate. Please note the Safety Plate is not the device to protect X-ray tube from destruction when over-rated power input but just to reduce the impact of housing rupture. Unexpected Malfunction : X-ray tube assembly may have the risk to be unexpectedly malfunctioning due to life termination or failure. If the serious problems caused by the above risk are expected, you are requested to have a contingency plan to avoid such a case. New Application : If you use the product with new application not to be mentioned in this specification or with different type of X-ray generator, please contact to us for confirming its availability.

16 3) Periodical Inspection To maintain long-time stable operation and service life, perform the periodical inspection at every regular intervals (at least once a year) in accordance with the items described on the following page. For any inspection items, if necessary, instruct LUCEM Co.. Ltd. personnel to carry out the periodical always operation the silicone compound may become dry, the coated state changed or the withstand voltage performance degraded. Insulation oil leakage from tube housing Thermal switch operation of the tube assembly High voltage cable connection part - Looseness of cable plug camping part - Silicone compound leakage and state of coating Roughness and bulb spatter on the target surface of the X-ray tube. Extremely abnormal noise and or vibration due to X-ray tube anode rotation Abnormal rotation of the air circulator of the tube assembly. Grounding wire and grounding resistance. Indication of tube voltage meter, tube current meter, and other meters. Timing phase deviation and time accuracy of the exposure timer. Operation of the starter for the tube assembly. Brightness and image quality of X-ray image intensifier. 4) Others X-ray tube ass y should have the -ray X limiting equipment mounted on the X-ray port to protect unnecessary radiation. X-ray tube ass y is not allowed is not allowed to use in the atmosphere of flammable or corrosive gas. If the input power exceeds X-ray tube ass`y specification, it cause the over temperature of anode, insert tube glass shatter, housing sealing parts rupture, human injury including burns due to hot oil escape and fire accident due to flaming anode target. The X-ray generator should have a protective function which manages input power to be within X-ray tube ass y specification. X-ray tube ass y is covered with lead inside tube housing to protect unnecessary radiation. The lead is harmful for human health. Dispose the scrapped products according to the requirement of local regulation. Page 16

17 X-ray tube ass y has insulation oil contained for high voltage stability. The insulation oil is poisonous for human health. If it is exposed to the non-restricted area, it should be disposed as following to the local regulation. According to the operating conditions, the filament characteristics might be changed to lead to the over rate exposure to X-ray tube ass y. To prevent the X-ray tube ass y from being damaged, please adjust the tube current regularly. Please don t touch on X-ray tube ass y just after operation due to high temperature. X-ray tube assembly is not allowed to lift more than 1 meter during transportation. X-ray tube assembly is not allowed to stack more than 2 stories. If any malfunction of the X-ray tube ass y is noticed, please contact to us immediately. Avoid fire and explosion hazard. An explosion hazard may result from the use of flammable anesthetics, skin cleansing agents and disinfectants. When cleaning the device, pay special attention so that cleaning liquid or any liquid may not soak into the inside of device. If any liquid soak into the inside of device, do not connect power line, do not use device, and contact service center. This equipment produces ionizing radiation. Observe proper safety practices during operation. The requirement to wear personal protective equipment such as lead aprons, dosimetry badges etc is governed by individual states and may vary from state to state. Other safety information follows the product-mounting system information. The tube assembly contains a high-vacuum product that can implode on incorrect handling, such as by impact, striking, dropping down. Use of the X-ray tube assembly is forbidden if signs of mechanical, electrical or radiation-related defects are present. WARNING: To avoid the risk of electric shock, this equipment must only be connected to a supply mains with protective earth. Page 17
