四柱油壓機，其實也就是油壓機。說白了，只不過在設計基礎之上建立“四條柱子”，因此得名叫做四柱油壓機。這樣的設計理念有一定的道理的，一定程度上保證了油壓機的穩定性，二來就是方便移動，即在四柱油壓機的機械設備底盤下也裝置移動的輪子。
那(nei)如(ru)何操作四柱油壓機呢(ni)？
1 外接AC380V三相四線電(dian)源，需要零線。加入(ru)油(you)壓油(you)（熱(re)帶為68#，寒帶為32#）油(you)量至少(shao)加至郵(you)箱容量80%或(huo)以上(shang)(shang)莜面計上(shang)(shang)限為準。
2 打開(kai)開(kai)關，電源指示燈亮。
3 首先(xian)按一下馬達(da)ON，立即再(zai)按馬達(da)OFF，觀察(cha)電機的運轉(zhuan)是否正(zheng)確（電扇(shan)葉蓋標有運轉(zhuan)方向(xiang)箭頭）。正(zheng)確可得重新啟動馬達(da)ON，如果不正(zheng)確，要給電源調相，然后啟動馬達(da)ON。
手動：把手動/自(zi)動選(xuan)擇開(kai)關扳到(dao)手動位(wei)置(zhi)，按(an)點動下(xia)(xia)壓(ya)按(an)鈕開(kai)關油(you)缸下(xia)(xia)行(xing)，放手后停(ting)止下(xia)(xia)行(xing)，如果需要(yao)油(you)缸寸動下(xia)(xia)行(xing)，按(an)一下(xia)(xia)點動下(xia)(xia)壓(ya)按(an)鈕，油(you)缸會(hui)寸動下(xia)(xia)行(xing)。同理(li)，按(an)點動上(shang)升(sheng)，油(you)缸上(shang)升(sheng)和(he)寸動上(shang)升(sheng)。手動功能為(wei)用(yong)戶組裝夾(jia)具(ju)以及模(mo)具(ju)的校(xiao)正和(he)調整等使用(yong)。
自動(dong)(dong)：把手(shou)動(dong)(dong)/自動(dong)(dong)選擇開(kai)關扳至自動(dong)(dong)位(wei)置，然后啟動(dong)(dong)機臺前方雙按鈕（或(huo)踩(cai)一下(xia)(xia)(xia)腳踏(ta)開(kai)關)，油(you)(you)(you)缸下(xia)(xia)(xia)行(xing)，油(you)(you)(you)缸下(xia)(xia)(xia)行(xing)是(shi)受下(xia)(xia)(xia)壓(ya)(ya)計時(shi)器控制，當(dang)下(xia)(xia)(xia)壓(ya)(ya)計時(shi)時(shi)間(jian)調的(de)(de)越長(chang)(chang)下(xia)(xia)(xia)壓(ya)(ya)行(xing)程(cheng)就(jiu)越長(chang)(chang)，當(dang)下(xia)(xia)(xia)壓(ya)(ya)計時(shi)器所調至的(de)(de)時(shi)間(jian)到，油(you)(you)(you)缸即(ji)上(shang)(shang)(shang)升(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)；油(you)(you)(you)缸上(shang)(shang)(shang)升(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)是(shi)受上(shang)(shang)(shang)升(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)計時(shi)器控制，上(shang)(shang)(shang)升(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)計時(shi)器調的(de)(de)越長(chang)(chang)上(shang)(shang)(shang)升(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)行(xing)程(cheng)就(jiu)越高（受油(you)(you)(you)缸長(chang)(chang)限(xian)度(du))，當(dang)上(shang)(shang)(shang)升(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)計時(shi)時(shi)間(jian)到，油(you)(you)(you)缸停止上(shang)(shang)(shang)升(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)。一個動(dong)(dong)作(zuo)流(liu)程(cheng)結束（下(xia)(xia)(xia)壓(ya)(ya)計時(shi)時(shi)間(jian)的(de)(de)長(chang)(chang)短以(yi)及上(shang)(shang)(shang)升(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)計時(shi)時(shi)間(jian)的(de)(de)長(chang)(chang)短根據(ju)用(yong)戶加(jia)工產品(pin)的(de)(de)需(xu)要可自行(xing)調整)。油(you)(you)(you)缸在下(xia)(xia)(xia)行(xing)時(shi)，如遇(yu)緊急(ji)情(qing)況可按一下(xia)(xia)(xia)急(ji)升(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)按鈕開(kai)關，油(you)(you)(you)缸立即(ji)回升(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)，起到保護(hu)作(zuo)用(yong)。
5 壓(ya)力調(diao)(diao)整(zheng)：在(zai)機臺馬達(da)油泵附近(jin)有(you)一個壓(ya)力調(diao)(diao)整(zheng)閥(fa)。順(shun)時針旋動(dong)壓(ya)力增(zeng)大；逆時針旋動(dong)則壓(ya)力減(jian)少。
