What should be done if a jack starts to leak hydraulic fluid?

If a jack starts to leak hydraulic fluid, it is essential to remove it from service and address the leakage through repair or replacement. Hydraulic fluid plays a crucial role in the proper functioning of a jack, as it enables the lifting mechanism to operate smoothly and effectively. A leak not only impairs the performance of the jack, leading to inadequate lifting capabilities, but it can also pose safety risks.

Continuing to use a leaking jack could lead to a failure during operation, potentially causing injury or further damage. Attempting to seal the leak with tape is a temporary and ineffective solution that does not address the underlying issue, and adding more hydraulic fluid does not resolve the leak either; it merely masks the problem for a short period, potentially leading to bigger issues down the line. Therefore, the most responsible course of action is to take the jack out of service and repair or replace it, ensuring safe and reliable operation.
