What is a recommended practice regarding the stacker's maintenance during operation?

Conducting regular inspections is essential for maintaining the safe and efficient operation of a stacker. Regular inspections help identify potential issues before they become serious problems, ensuring that all components, including brakes, steering, and lifting mechanisms, are functioning correctly. This proactive approach allows operators to address wear and tear or any defects, reducing the likelihood of accidents, breakdowns, or equipment failures during operation.

The other options, while significant in their own contexts, do not provide as comprehensive a maintenance strategy. Limiting use can lead to operational inefficiencies and does not necessarily address wear and tear directly. Adjusting the load weight frequently could complicate operations and affect stability if not done correctly. Using the stacker only in daylight limits its use substantially, which may not be practical or efficient in many operational environments. Regular inspections stand out as the best practice for maintaining the stacker's performance and safety during operation.
