immediately lower the platform and stop all machine operation.

7) In the elevated state of the platform, the machine cannot run on uneven terrain, an unstable surface, or in other dangerous situations, or near these areas.

8) In the stowed state, the machine must run very carefully and reduce its speed when it runs on uneven terrain, unstable or smooth surface with stones, or near holes, or a steep slope.

9) Do not use the platform control station to release the platform when the platform is tilted, stuck, or its normal operation is obstructed by other nearby obstacles.
Before using the ground control station to release the platform, all personnel must exit the platform.

10) Do not use the platform to push or pull anything outside the platform.

11) Do not use the machine as a crane.

12) Do not place, fasten and fix or suspend loads on any component of the machine.

13) Do not place ladders or scaffolds within the platform or against any component of the machine.

14) Do not attach platforms to adjacent buildings.

15) Do not change or disable limit switch.

16) Do not tie platforms to adjacent components.
