After how many years or arrests should the BAK 12 be overhauled?

The correct response indicates that the BAK 12 should be overhauled after 10 years or 500 arrestments. This recommendation is grounded in the need to ensure reliable performance and safety standards for equipment that is subject to frequent use and operational stress. Overhauling the BAK 12 at this interval allows for maintenance checks, necessary repairs, and updates to technology and safety features that may have been developed since the equipment was first manufactured.

Regular overhauls are critical in maintaining the equipment's functionality and extending its operational life. By specifying both a time frame (10 years) and a usage threshold (500 arrestments), the guidelines ensure that the equipment does not exceed limits where wear and tear could lead to failures or safety hazards, reflecting best practices in maintenance and ensuring peak operational readiness.
