The water outlet hole on the spray arm faces the target surface. The spray arm of some spray cleaning machines is loose and rotated during use, resulting in that the spray arm cannot face the instrument. Many spray arms have holes on both sides; These holes can be adjusted up or down.

完整噴槍:部分醫院全部噴槍缺失，但機器仍在使用。如果噴淋臂缺失，清洗機無法正常運轉，因為水壓和水噴淋會大大削弱機械清洗效果。如果噴淋臂沒有了，不要使用墊圈。

Complete spray gun: all spray guns are missing in some hospitals, but the machine is still in use. If the spray arm is missing, the cleaning machine cannot operate normally, because the water pressure and water spray will greatly weaken the mechanical cleaning effect. Do not use gaskets if the spray arm is missing.

噴淋臂旋轉暢通:測試噴淋臂旋轉平穩均勻。

Smooth rotation of spray arm: test that the spray arm rotates smoothly and evenly.

清洗機底部的排水屏上無雜物:清洗機底部的排水屏會保留儀表組的污染物。篩網至少每天拆下清洗一次，或根據使用次數增加清洗次數。堵塞的篩網會阻礙水流和排水，從而影響清洗機的清洗效果。

There are no sundries on the drainage screen at the bottom of the cleaning machine: the drainage screen at the bottom of the cleaning machine will retain the pollutants of the instrument cluster. The screen shall be removed and cleaned at least once a day, or the cleaning times shall be increased according to the times of use. The blocked screen will hinder the water flow and drainage, thus affecting the cleaning effect of the cleaning machine.

儀表機架聯軸器與歧管正確對準。確保洗衣機的水/洗滌劑進口與清洗架歧管正確對齊。如果沒有對準，會影響水流、水的分布和水壓，可能導致墊圈運轉異常。水壓不足會使噴淋臂無法正常工作，削弱機械清洗效果。

The instrument rack coupling is correctly aligned with the manifold. Ensure that the water / detergent inlet of the washing machine is correctly aligned with the cleaning rack manifold. If not aligned, it will affect the water flow, water distribution and water pressure, which may lead to abnormal operation of the gasket. Insufficient water pressure will make the spray arm unable to work normally and weaken the mechanical cleaning effect.

噴淋臂襯套完好無損:確保所有襯套、聯軸器、墊圈等完好無損，無裂縫或損壞。

Spray arm bushing intact: ensure that all bushings, couplings, washers, etc. are intact without cracks or damage.

洗滌劑/化學品輸送管道清晰、功能齊全:目視檢查所有洗滌劑和其他化學品輸送管道及連接端口，確保管道暢通、清潔、無堵塞、堵氣、無扭結。還應檢查管道上的磨損痕跡、損壞或泄漏。如果輸送管道有缺陷，清洗液的濃度可能不正確，從而使清洗周期失效。

Detergent / chemical transmission pipeline is clear and fully functional: visually inspect all detergent and other chemical transmission pipelines and connection ports to ensure that the pipeline is unblocked, clean, free of blockage, air blockage and kink. The pipes shall also be inspected for wear marks, damage or leakage. If the delivery pipeline is defective, the concentration of the cleaning solution may be incorrect, resulting in the failure of the cleaning cycle.

檢查所有化學品和清洗劑的濃度是否正確:確保清洗劑和其他化學品容器內的余量充足，并確保輸配管道正確連接到相應的容器上。

Check whether the concentration of all chemicals and cleaning agents is correct: ensure that the margin in the container of cleaning agents and other chemicals is sufficient, and ensure that the transmission and distribution pipeline is correctly connected to the corresponding container.

觀察清洗機的整體狀況:機艙內表面應清潔，無污垢、水垢等污染物。這些都會影響清洗機的性能和清洗效果。污漬和水垢可能表明水質問題，化學物質濃度高等。確保所有適用的墊圈、密封圈和記錄儀處于正常狀態。

Observe the overall condition of the cleaning machine: the inner surface of the engine room shall be clean and free of dirt, scale and other pollutants. These will affect the performance and cleaning effect of the cleaning machine. Stains and scale may indicate water quality problems and high chemical concentrations. Ensure that all applicable gaskets, seals and recorders are in good condition.
