Why must pulls be done slowly and carefully?

• A. To prevent over-pulling or additional damage
• B. To maximize pull force quickly
• C. To avoid using proper tools
• D. To create more misalignment

Answer: (A)

Pulls must be done slowly and carefully because metal shapes themselves gradually respond to force. Using light, incremental pulls lets the panel flow back toward its original contour without overshooting, which would cause thinning, distortion, or new dents. This controlled approach gives you the ability to stop as soon as the alignment improves and before damage occurs, especially when working against curved or stressed areas. Rushing to apply a high force increases the risk of over-pulling, tearing, or creating additional misalignment. The other options describe outcomes you don’t want and overlook the need for patient control and proper technique.
