要注意液壓升降(jiang)機氣蝕和溢流噪(zào)聲，液壓升降機作(zuo)業中要時刻注意(yì)液壓泵和溢流閥(fá)的聲音，如果液壓(ya)泵出現“氣蝕”噪聲(sheng)，經排氣後不能消(xiāo)除，應查明原因排(pái)除故障後才⭐能使(shi)用。如果液🚩壓升降(jiang)機某執行元件在(zài)沒有負荷♋時動作(zuo)緩慢，并伴有溢流(liú)閥溢流聲響，應立(li)即停機檢修。操作(zuò)手要保持穩定🤞，因(yīn)為每台設備操縱(zong)系統的自由間隙(xì)都有一定差異，連(lian)接部位的磨損程(chéng)度不同因而其間(jian)隙也不同☂️，發動機(jī)及✍️液壓系統出力(li)的大小也不盡相(xiang)同。
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. 

隻有使用液壓(ya)升降機的操作手(shou)認真摸索，修正自(zì)己的操縱動作以(yǐ)适應設備的個性(xìng)，經過長期作業後(hou)，才能養成符合設(she)備個性的良🆚好操(cao)作習慣。一般機械(xie)行業堅持定人定(ding)機制度，這也是因(yin)素之一。
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.
