要注(zhu)意液壓(ya)升降機(ji)氣蝕和(he)溢流噪(zao)聲，液壓(ya)升降機(ji)作業中(zhong)要時刻(ke)注意💜液(ye)壓泵和(he)溢🏃‍♂️流閥(fa)的聲音(yin)，如果液(ye)壓泵出(chu)現“氣蝕(shi)”噪🌈聲，經(jing)排氣後(hou)不能消(xiao)🍉除，應⭐查(cha)明原因(yin)排除故(gu)障後才(cai)能使用(yong)。如果液(ye)⛱️壓升降(jiang)機某執(zhi)行元件(jian)㊙️在沒有(you)負荷時(shi)動作緩(huan)慢，并伴(ban)有溢流(liu)閥溢流(liu)聲響，應(ying)立即停(ting)機⚽檢修(xiu)。操作手(shou)⛷️要保持(chi)穩定，因(yin)為每台(tai)設備操(cao)縱系統(tong)🐪的自由(you)間隙都(dou)有一定(ding)差異，連(lian)接部位(wei)的磨損(sun)程度不(bu)同因而(er)其間隙(xi)也不同(tong)，發動機(ji)及液壓(ya)系統出(chu)力🌍的大(da)小也不(bu)盡相同(tong)。
Attention should be paid to the hydraulic lift and overflow cavitation noise, hydraulic lift operation should always pay attention to the hydraulic pump and overflow valve sound, if the hydraulic pump "cavitation" noise, the exhaust can not be eliminated, should be identified to cause after troubleshooting. If a hydraulic lift actuator does not move slowly when there is no load, accompanied by overflow valve overflow sound, should immediately stop maintenance. The operator should remain stable, because the free clearance per device control system there are some differences in the degree of wear, the connecting parts of the different so the gap is different, the size of the output of the engine and hydraulic system are not the same. 

隻有使(shi)用液壓(ya)升降機(ji)的操作(zuo)手認真(zhen)摸索，修(xiu)正自己(ji)的操縱(zong)動作以(yi)适應設(she)備🈲的♋個(ge)性👄，經過(guo)長期作(zuo)業後，才(cai)能養成(cheng)符合設(she)備🔅個性(xing)的良好(hao)操作習(xi)❓慣。一般(ban)機械行(hang)業堅持(chi)定人定(ding)機制度(du)，這也是(shi)❌因素之(zhi)一。
Only the use of hydraulic lift operator carefully explore, modify their manipulation to adapt to the personality of the device, after long-term operations, in order to develop a good personality in line with the operating habits of

equipment. General machinery industry adhere to the fixed machine system, which is one of the factors.
