2. Safety Precautions

Before using your chain hoist, read and follow these safety instructions:

✅ Check Before Use: Inspect the hoist, 钩子, and chain for damage or wear. Do not use if any parts are damaged.
✅ Load Limit: Never exceed the rated load capacity. Overloading can cause serious accidents.
