What should be done with all hydraulically raised attachments before leaving the excavator?

Before leaving an excavator, it is essential to lower all hydraulically raised attachments to the ground flat. This practice is critical for maintaining safety on work sites. Lowering the attachments ensures they are in a stable and secure position, minimizing the risk of accidental movement or tipping while personnel are nearby. It also prevents potential damage to the equipment and surrounding environment.

Properly lowering the attachments helps to eliminate hazards associated with working around heavy machinery, which could result in injuries. Additionally, grounding the attachments when the machine is not in use prevents unintended hydraulic leaks, which could affect the overall operation of the excavator. Therefore, the correct action is to lower the hydraulically raised attachments to the ground flat before dismounting the excavator.
