**Do Not Overload:** The lifting force must not exceed the rated lifting capacity.
**Ensure a Stable Foundation:** The base of the jack and the load support point must be firm and level.
**Do Not Support for Extended Periods:** Jacks are lifting tools, not permanent support devices. Rigid supports must be used for protection during operation.
**Personnel Safety:** During lifting, never place any part of your body under the load. The operator should stand in a safe position.
**Regular Inspection:** Before use, check hoses and connectors for damage and leaks.
**Synchronization Control:** When using multi-cylinder lifting, a flow divider valve or synchronization control system must be used to prevent uneven load distribution.
