What can happen if the loader arm service lock is not used during maintenance?

Using the loader arm service lock during maintenance is crucial for ensuring safety. When the service lock is not engaged, the loader arm can unintentionally move, leading to potential hazards. This situation presents a significant risk of injury to the operator and others who may be in the vicinity. The unexpected movement of the arm can crush, pinch, or strike someone, resulting in serious accidents.

In this context, safety protocols are designed to minimize risks during maintenance tasks. Properly securing the loader arm with the service lock is a foundational precaution that protects workers on job sites. Therefore, understanding the importance of using the service lock is vital for maintaining a safe working environment during equipment maintenance.
