1.檢查重慶升降貨梯所有的液壓管道和接頭。管道不能有破損，接頭不能有松動，必需將所有接頭擰緊。Check all hydraulic pipes and fittings of Chongqing elevator. The pipe can not be damaged, the joint can not be loose, it is necessary to tighten all the joints.

2.液壓油的油質和油位。升降機全程升起，在這位置時，液壓地面應高出箱底 40～50 毫米。如發現液壓油變暗、發粘或者有砂礫等異物， 應及時更換(32#液壓油)。The hydraulic oil oil and oil. Lift the whole rise, in this position, the hydraulic ground should be higher than the 40 to 50 mm. If the hydraulic oil is found to be dark, sticky or gravel and other foreign bodies, should be replaced in a timely manner (32# hydraulic oil).

3.各部位均加注一些潤滑油，延長升降機軸承使用壽命。 檢查重慶升降貨梯滾輪、中間軸及軸承，油缸銷軸及軸承，臂架鉸軸及軸承等有無磨損。All parts are filled with lubricating oil, prolong the service life of the lift bearing. Check Chongqing lifting elevator, roller shaft and bearing, cylinder pin shaft and bearings, boom hinge shaft and bearings are worn.

4.液壓系統任何部位之間，必需首先卸壓，以免壓力油噴出，升降機工作臺溘然下滑。Between any part of the hydraulic system, must first pressure relief, in order to avoid pressure oil spray, the lift table suddenly fell.

5.不得任意調整溢流閥。液壓升降機系統中的每個元件都是在劃定壓力下工作的。任意調整溢流閥后，可能會造成液壓系統非正常運轉。May not adjust the relief valve. Each of the components in the hydraulic lift system is under pressure to work under pressure. Any adjustment of the relief valve, may cause the abnormal operation of the hydraulic system.

6.在升降機工作平臺下面檢驗時，必需吊住、支撐升降機工作平臺，以防升降機溘然下降.In the lift work platform for inspection, must hang, supporting lift work platform, to prevent the elevator suddenly fall.

7.非重慶升降貨梯專業職員不得隨意拆裝電器，以防觸電或誤接。Non Chongqing elevator goods ladder professional staff shall not be arbitrarily disassembled electrical appliances, in order to prevent electric shock or mistake.
