本機特點：
一、本機設計簡易故障率低 。
二、密閉式設計可防止溶劑揮發 ，避免因沾藥水造成容器內的污染，可節約25%左右藥水的浪費。
三、不需經沾藥水的過程 ，可提高10%以上之工作效率 ，在操作中有充分的自我檢視時間。
四、腳踏開關及壓管開關之氣壓須維持在4KG/cm²左右 。
五、壓管開關內之軟管需每個月更換一次 ，以免造成破損導致漏膠水情況，屬月保養。
六 、JW-302配備可調式氣動攪拌器，可將容器內添加物自動攪拌均勻，避免有沉澱及濃度不均勻的現象。
七 、若溶劑內加入三氯三聚異氰酸（B粉）強氧化劑，需在有效時間（2-4小時）內使用完，並且注意使用時須將攪拌器速度調慢，藥水罐及管壁上容易附着B粉，須每天清理。
Features :
1. the design of the machine is easy to fail, and the failure rate is low.
2. The closed design can prevent the dissipation of solvents and avoid the pollution in the container caused by the wetting, which can save about 25% of the waste of the water.
3. The process of not needing to be dipped in medicinal water can improve the work efficiency by more than 10%, and there is sufficient self-examination time in the operation.
4.The air pressure of pedal opening and pressure pipe opening must be maintained at about 4KG/cm².
5. The software management within the shutdown shall be replaced once a month to avoid water leakage caused by damage, and shall be maintained on a monthly basis.
6. JW-302 is equipped with a adjustable pneumatic mixer, which can automatically mix the additives in the container to avoid the phenomenon of sedimentation and uneven moisture.
7. If trichlorotrimeric acid (B powder) strong oxidant is added to the solution, it needs to be used within the effective time (2-4 hours), and it should be noted that the speed of the mixer must be adjusted slowly when using, and B powder is easy to adhere to the wall of the water tank and pipe, and it must be cleaned every day.
