What should be done if a stacker's load feels unstable during operation?

If a stacker's load feels unstable during operation, the correct action is to immediately lower the load. This ensures safety for both the operator and those nearby. An unstable load can lead to accidents, such as tipping or dropping, which can cause injury or damage. By lowering the load, the operator can regain control and stabilize the stacker, bringing the load closer to the ground where it is naturally more stable.

Proceeding with caution may lead to further instability and risk, as the operator could inadvertently increase the risk of an accident while attempting to navigate with a shaky load. Increasing speed is dangerous in this situation, as it can aggravate the instability and make the load even more difficult to control. Lifting the load higher will also exacerbate the problem, as higher loads have a greater risk of tipping over. Therefore, lowering the load is the most prudent and safe response to maintain control and ensure safety during operation.
