要(yao)注意液(yè)壓升降(jiàng)機氣蝕(shí)和溢流(liu)噪聲，液(yè)壓升降(jiang)機作業(yè)中要時(shi)刻注意(yì)液♊壓泵(beng)和溢流(liu)閥的聲(sheng)音，如果(guo)液壓泵(beng)出現“氣(qì)蝕”噪聲(sheng)，經👈排氣(qì)後不能(neng)消除，應(ying)查明原(yuan)因排除(chu)故障後(hou)才👨‍❤️‍👨能使(shǐ)用。如果(guǒ)液壓升(sheng)降機某(mou)執行元(yuan)件在沒(méi)有負荷(hé)時動作(zuò)緩慢，并(bing)伴有溢(yi)流閥溢(yi)流聲響(xiang)，應立即(ji)停機🏃🏻‍♂️檢(jiǎn)修。操作(zuò)手要保(bao)持穩定(ding)，因為每(mei)台設⭐備(bei)操縱系(xi)統❗的自(zì)由間隙(xì)都有一(yi)定差異(yi)，連❄️接部(bù)位的磨(mó)損程度(du)不同因(yīn)而其間(jian)隙也不(bú)同🆚，發動(dong)機及液(ye)壓系統(tong)出力的(de)大小也(ye)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(you)使用液(ye)壓升降(jiàng)機的操(cāo)作手認(ren)真摸索(suǒ)，修正自(zì)己的操(cao)縱動作(zuo)以适應(yīng)♻️設備的(de)個性，經(jing)過長期(qī)作業後(hou)，才能養(yang)成符合(hé)設備♋個(ge)性💁的良(liang)好操💔作(zuo)習慣。一(yi)❤️般機械(xiè)行業堅(jian)持定人(ren)定機制(zhi)度，這也(ye)是👉因素(sù)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.
