1、噴嘴無污染物或堵塞。如果有噴孔阻塞，水流和水壓將受到阻礙，從而影響清 洗機的性能。數控高壓清洗機的水在清洗周期中是再循環的，其中攜帶的污染物可能停留在噴淋臂內。噴淋臂需定期清潔。
1. The nozzle is free of contamination or blockage. If the orifice is blocked, the water flow and water pressure will be blocked, which will affect the performance of the washer. The water of the CNC high-pressure washer is recycled during the cleaning cycle, and the pollutants carried in it may stay in the spray arm. The spray arm should be cleaned regularly.
2、 噴淋臂上的出水孔朝著目標表面。有的清洗機的噴淋臂在使用過程中松動旋轉，導致噴淋無法朝向器械。許多噴淋臂兩邊都有孔；這些孔可以調節朝上或朝下。
2. The water outlet hole on the spray arm faces the target surface. The spray arm of some cleaning machines is loose and rotated during use, which makes the spray unable to face the instrument. Many spray arms have holes on both sides; These holes can be adjusted upward or downward.
3、 噴淋臂齊全：有的醫院的噴淋臂全部缺失但機器仍在使用。如果噴淋臂缺失清洗機無法正常運轉，因為水壓和噴水會大大削弱機械清洗作用。如果噴淋臂缺失則不得使用該清洗機。
3. Complete spray arms: some hospitals have no spray arms but the machine is still in use. If the spray arm is missing, the washer cannot operate normally, because the water pressure and water spray will greatly weaken the mechanical cleaning effect. Do not use the washer if the spray arm is missing.
4、 噴淋臂旋轉無阻礙：測試噴淋臂確保旋轉順滑均勻。
4. Spray arm rotation is unimpeded: test the spray arm to ensure smooth and even rotation.
5、清洗機底部排水篩無雜物：清洗機底部的排水篩會留滯來自器械組的污染物。應至少每天取下篩網并清洗，或根據使用次數增加清洗頻率。阻塞的篩網會阻礙水流和排水，從而影響清洗機的清洗效力。

5. The drain screen at the bottom of the washer is free of impurities: the drain screen at the bottom of the washer will retain pollutants from the instrument set. The screen should be removed and cleaned at least daily, or more frequently depending on the number of uses. Blocked screen will block water flow and drainage, thus affecting the cleaning effectiveness of the washer.
6、器械架聯軸器與歧管正確對齊。確保清洗機水/清洗液進口與清洗架歧管正確對齊，如果沒有對齊，水流、水分布及水壓都會受到影響，并且都可能導致清洗機運行不正常。水壓不足會導致噴淋臂無法正常運轉，還會削弱機械清洗作用。
6. The instrument rack coupling is correctly aligned with the manifold. Make sure that the washer water/detergent inlet is correctly aligned with the cleaning rack manifold. If it is not aligned, the water flow, water distribution and water pressure will be affected, and may cause the washer to operate abnormally. Insufficient water pressure will cause the spray arm to fail to operate normally and weaken the mechanical cleaning effect.
7、噴淋臂軸套存在且未受損：確保所有軸套、聯軸器、墊圈等存在且無任何裂痕或破損。
7. Spray arm shaft sleeve is present and undamaged: ensure that all shaft sleeves, couplings, washers, etc. are present and free from any cracks or damage.
8、清洗劑/化學品輸送管道清晰、功能正常：目視檢查所有清洗劑等化學品輸送管道和連接端口：確保它們清晰，清潔，無阻塞、滯留空氣、扭結。管道上的磨損痕跡、破損或泄漏也應注意檢查。如果輸送管道有缺陷，則清洗液的濃度可能不正確從而使清洗循環無效。
8. Cleaning agent/chemical delivery pipeline is clear and functional: visually inspect all cleaning agent and other chemical delivery pipelines and connection ports: ensure that they are clear, clean and free of blockage, trapped air and kinks. Attention shall also be paid to the inspection of wear marks, damages or leaks on the pipeline. If the delivery pipe is defective, the concentration of the cleaning solution may be incorrect and the cleaning cycle may be invalid.
9、檢查所有化學品、清洗劑濃度是否正確：確保清洗劑及其他化學品容器內的余量充足，確保輸送分配管道正確連接到對應的容器。
9. Check whether the concentration of all chemicals and cleaning agents is correct: ensure that there is sufficient margin in the containers of cleaning agents and other chemicals, and ensure that the transmission and distribution pipes are correctly connected to the corresponding containers.
10、觀察清洗機總體情況：艙體內表面應清潔，無污點、水垢及其它污染物堆積。這些都可能影響清洗機的性能和清洗效果。污點和水垢可能表明有水質、化學品濃度過高等問題。確保任何適用的墊圈、密封圈、記錄器都處于正常狀態。
10. Observe the overall condition of the cleaning machine: the internal surface of the cabin shall be clean, and there shall be no dirt, scale and other pollutants. These may affect the performance and cleaning effect of the cleaning machine. Stains and scale may indicate problems such as high water quality and chemical concentration. Ensure that any applicable gaskets, sealing rings and recorders are in normal condition.
11、檢查艙體內照明燈具工作正常：清洗機擁有視窗和內部照明燈具允許在循環過程中觀察清洗機的性能。循環過程中需觀察噴淋臂是否正常運行，無器械/托盤阻礙清洗機的性能。觀察水流，確保無泡沫過多等跡象。
11. Check that the lighting fixtures in the cabin work normally: the washer has a window and internal lighting fixtures, allowing the performance of the washer to be observed during the cycle. During the circulation, it is necessary to observe whether the spray arm operates normally, and no instrument/tray hinders the performance of the washer. Observe the water flow to ensure that there is no sign of excessive foam.
