1. When using the hydraulic cargo elevator, please do not lift the platform when the platform is not firm, the outriggers are not adjusted, leveled, and the landing is not firm.

2、不要在平台上有人或升起时调停或收起外伸支腿。

2. Do not stop or retract the outrigger when there is someone on the platform or when it is raised.

3、不要在平台升起时移动机械，如需移动请先将平台缩合，放松支腿。

3. Do not move the machine when the platform is raised. If you need to move, please retract the platform and loosen the legs.

4、不要在作业时向外用力推拉物体。

4. Do not push or pull objects outward during operation.

5、不要使用液压货梯晋升货物或配备，因为它于载天时工具作业。

5. Do not use the hydraulic cargo elevator to lift the goods or equipment, because it is only limited to the tool operation when it is loaded.

6、请勿以本机械作为电焊中线接地之用。

6. Do not use this machine for welding neutral grounding.

7、请勿在全体能够预感挫伤环境下使用本机。

7. Do not use this machine in an environment where all people can feel bruise.

8、液压货梯下严禁站人或堆放杂物。

8. It is strictly forbidden to stand or stack sundries under the hydraulic cargo ladder.

拆卸液压货梯液压油箱加油盖、滤清器盖、检测孔、液压油管等部位，造成系统油道暴露时要避开扬尘，拆卸部位要先彻底清洁后才能打开。如拆卸液压油箱加油盖时，先除去油箱盖四周的泥土，拧松油箱盖后，残留在接合部位的杂物(不能用水冲洗以免水渗入油箱)，确认清洁后才能打开油箱盖。如需使用擦拭材料和铁锤时，应选择不掉纤维杂质的擦拭材料和击打面附着橡胶的专用铁锤。

Remove the hydraulic oil tank filler cap, filter cap, inspection hole, hydraulic oil pipe and other parts of the hydraulic cargo elevator. When the system oil passage is exposed, avoid dust. The removed parts must be thoroughly cleaned before opening. For example, when removing the hydraulic tank filler cap, remove the mud around the tank cap first, loosen the tank cap, remove the debris left at the joint (do not flush with water to prevent water from seeping into the tank), and open the tank cap only after confirming that it is clean. If it is necessary to use wiping materials and hammers, the wiping materials that do not remove fiber impurities and the special hammers with rubber attached to the striking surface should be selected.

液压元件、液压胶管要认真清洗，用高压风吹干后组装。选用包装完好的滤芯(内包装损坏，虽然滤芯完好，也可能不洁)。换油时同时清洗滤清器，安装滤芯前应用擦拭材料认真清洁滤清器壳内底部污物。

The hydraulic components and hydraulic hoses shall be carefully cleaned and dried with high pressure air before assembly. Select the filter element with intact packaging (the inner packaging is damaged, although the filter element is intact, it may also be dirty). Clean the filter at the same time when changing the oil, and carefully clean the dirt at the bottom of the filter housing with wiping materials before installing the filter element.

重要的一点是，清洗油必须使用与系统所用牌号相同的液压油，油温在45～80℃之间，用大流量尽可能将系统中杂质带走。液压系统要反复清洗三次以上，每次清洗完后，趁油热时将其全部放出系统。清洗完毕再清洗滤清器、更换新滤芯后加注新油。

It is important to use hydraulic oil with the same brand as the system for cleaning oil. The oil temperature is between 45 and 80 ℃. The impurities in the system should be removed as much as possible with large flow. The hydraulic system shall be cleaned repeatedly for more than three times. After each cleaning, all the hydraulic system shall be drained when the oil is hot. After cleaning, clean the filter and replace the filter element with new oil.
