What should be regularly checked to ensure safe functioning of a stacker?

Regularly checking the hydraulic system's fluid levels is crucial for the safe functioning of a stacker. The hydraulic system is responsible for lifting and lowering the stacker’s forks, and maintaining the correct fluid levels ensures that the hydraulic system operates efficiently and effectively. Insufficient fluid can lead to decreased lifting power, slower movements, or even failure of the hydraulic components, which may result in accidents or equipment damage. Keeping an eye on these levels contributes to overall safety and operational reliability.

While the driver's personal safety gear, the surroundings of the loading area, and the static nature of the load are indeed important aspects of workplace safety, they do not directly impact the stacker's operational functionality in the same way that the hydraulic fluid levels do. They are more about general safety practices rather than the specific mechanical functioning of the stacker itself. Therefore, focusing on the hydraulic system’s fluid levels is key to ensuring the stacker operates safely and effectively.
