1.升降货梯液压油的油质和油位。升降机全程升起，在这位置时，液压地面应高出箱底40～50毫米。如发现液压油变暗、发粘或者有砂砾等异物，应及时更换(32#液压油)。Lifting elevator 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 (32# hydraulic oil).

Check the hydraulic lift roller, shaft and bearing, cylinder pin shaft and bearings, boom hinge shaft and bearings are worn.

3.升降货梯液压系统任何部位之间，必需首先卸压，以免压力油喷出,升降机工作台溘然下滑。Between any part of the hydraulic system of lifting elevator, must first pressure relief, in order to avoid pressure oil spray, the lift table suddenly fell.

4.不得任意调整溢流阀。液压升降货梯系统中的每个元件都是在划定压力下工作的。任意调整溢流阀后，可能会造成液压系统非正常运转。No relief valve. Each component in the hydraulic elevator system is working under pressure. Any adjustment of relief valve may cause abnormal operation of hydraulic system.

5.在升降货梯工作平台下面检验时，必需吊住、支撑升降机工作平台，以防升降机溘然下降.The lifting elevator inspection work platform, must hang, supporting lift work platform, to prevent the elevator suddenly fall.

6.非专业职员不得随意拆装液压升降货梯的电器，以防触电或误接。Non professional personnel shall not disassemble and assemble the electric appliance of the hydraulic lifting ladder to prevent electric shock or wrong connection.
