要注意(yì)液壓升降(jiang)機氣蝕和(he)溢流噪聲(shēng)，液壓升降(jiàng)機作業中(zhong)要時刻注(zhù)意液壓泵(beng)和溢流閥(fá)的聲音，如(rú)果液壓泵(bèng)出現“氣蝕(shí)”噪聲，經排(pái)氣後不🔴能(neng)消除，應查(chá)明原因排(pai)除故障後(hou)才能使用(yòng)。如果液🙇‍♀️壓(ya)升降機某(mou)執行元件(jiàn)🏃在沒有負(fù)荷🔴時動作(zuo)緩慢，并伴(bàn)有🎯溢流閥(fá)溢👣流聲響(xiǎng)，應立即停(ting)機👄檢修。操(cāo)作手要保(bǎo)持穩定，因(yīn)為每台設(she)備操縱系(xì)統的自由(you)間隙都🌐有(you)一定差異(yì)，連接部位(wèi)的磨損程(chéng)度不同因(yin)而其間隙(xì)也不同，發(fa)動機及液(ye)壓系統出(chū)力的大小(xiǎo)也不盡相(xiàng)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(shi)用液壓升(sheng)降機的操(cāo)作手認真(zhen)摸索，修正(zheng)自己的操(cao)縱動作以(yi)适應設備(bèi)☀️的個性，經(jing)過長期作(zuò)業後，才能(néng)養成符合(hé)設備個性(xìng)🈲的良好操(cāo)㊙️作習🐉慣。一(yī)般機械行(hang)業堅持定(dìng)人定機制(zhì)度，這也是(shì)因素之一(yī)。
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.
