What should you do if your jack becomes unstable while lifting?

If your jack becomes unstable while lifting, immediately stopping the use of the jack and safely lowering the vehicle is the correct course of action. Stability is critical when operating a jack, as an unstable jack can pose serious risks to both the operator and bystanders. Lowering the vehicle safely helps ensure that it does not fall or shift unexpectedly, which could lead to injuries or damage.

Continuing to use the jack, even cautiously, would unnecessarily increase the risk of a failure, as the problem that caused the instability still exists. The option to reposition the jack without checking disregards the need for proper assessment, which could lead to further instability and danger. Lifting heavier loads is also unsafe since it exacerbates the risk of an unstable jack, leading to potential catastrophic consequences. Ensuring safety through immediate discontinuation and stabilization is paramount in these situations.
