When should you use a pulling system during repair?

Using a pulling system during repair is essential when correcting structural misalignment in frames or panels. This process often occurs after a vehicle has been involved in a collision, where the frame or body may have become bent or distorted. A pulling system is designed to exert force in a controlled manner, allowing technicians to accurately realign the frame or panels back to their original specifications. This is crucial not only for the aesthetic quality of the repair but also for the safety and structural integrity of the vehicle, as proper alignment ensures that the vehicle will handle correctly and that safety features perform as intended.

The other options do not align with the specific purpose of a pulling system. For instance, applying paint evenly is a task for spray guns or paint applicators, while removing rust involves different techniques such as sanding or using chemical rust removers. Cleaning up debris from a collision site would typically involve manual labor or the use of cleaning equipment, not a pulling system designed for frame and panel correction. This context helps clarify why the use of a pulling system is unique and critical in the repair of structural misalignments.
