2. Safety Information
WARNING: Failure to follow these safety instructions may result in serious injury or death.
- Always inspect the hoist, chain, and hooks for damage or wear before each use. Do not use if any components are compromised.
- Ensure the hoist is securely attached to a structure capable of supporting the maximum rated load plus the weight of the hoist itself.
- Never exceed the rated load capacity of 0.25 tons (550 lbs). Overloading can cause structural failure and severe injury.
- Keep hands and body clear of the load and chain during operation.
- Do not use the hoist to lift people or loads over people.
- Ensure the load is balanced and properly secured before lifting.
- Avoid sudden jerking or swinging of the load. Operate the hoist smoothly.
- Do not leave a suspended load unattended.
- Only trained and authorized personnel should operate this equipment.
- Store the hoist in a dry, clean place when not in use to prevent corrosion and damage.

- Upper Hook: For attaching the hoist to a support structure. Features 360° rotation and a safety latch.
- Hoist Body: Contains the internal mechanisms, including gears and the braking system. Made of lightweight aluminum alloy.
- Hand Chain: Used to operate the lifting mechanism. Pulling this chain raises or lowers the load.
- Load Chain: The chain that supports the load. Made of G80 manganese steel for high strength.
- Lower Hook: For attaching to the load. Equipped with a safety latch.
- Braking System: A mechanical load brake ensures the load is held securely at any position and meets ANSI/ASME B30.16 requirements.

5. Setup & Installation
Proper setup is crucial for safe operation. Follow these steps for installation:
- Choose a Secure Anchor Point: Select an overhead support structure (e.g., I-beam, sturdy truss, or dedicated hoist mount) that is certified to safely support at least the maximum rated load of the hoist plus the weight of the hoist itself.
- Attach the Upper Hook: Open the safety latch on the upper hook and securely attach it to the chosen anchor point. Ensure the latch closes completely and the hook is seated properly. The 360° rotation allows for flexible positioning.
- Inspect the Hoist: Before first use, and before each subsequent use, perform a thorough visual inspection of the entire hoist. Check the load chain for kinks, twists, damage, or excessive wear. Verify that both the upper and lower hooks are free from deformation and that their safety latches operate correctly. Ensure the hand chain moves freely.
- Clear the Area: Ensure the area below and around the hoist is clear of personnel and obstructions before lifting any load.
6. Operating Instructions
Operating the YATOINTO Hand Chain Hoist is straightforward, but requires attention to safety and proper technique.
- Attach the Load: Open the safety latch on the lower hook and securely attach it to the load. Ensure the load is balanced and the hook is properly seated. Close the safety latch.
- Lifting the Load: To lift the load, pull the hand chain downwards. The hoist's internal gears will engage, and the load chain will retract, raising the load. Pull steadily and smoothly.
- Lowering the Load: To lower the load, pull the other side of the hand chain (or the side that causes the load to descend). The mechanical brake will control the descent, allowing for smooth and precise lowering. Maintain control of the hand chain at all times.
- Stopping the Load: Release the hand chain to stop the load at any desired height. The mechanical brake will automatically engage to hold the load securely.
- After Lifting: Once the load is safely placed and supported, release the tension on the hoist and detach the lower hook from the load.

7. Maintenance
Regular maintenance ensures the longevity and safe operation of your hoist.
- Regular Inspection: Conduct daily or pre-use inspections as described in the safety section. Pay close attention to the load chain, hooks, and the overall housing for any signs of damage, wear, or corrosion.
- Cleaning: Keep the hoist clean and free from dirt, debris, and excessive grease. A clean hoist operates more smoothly and allows for easier inspection.
- Lubrication: Periodically lubricate the load chain and internal moving parts as recommended by the manufacturer (though specific lubrication points are not detailed in the provided data, general hoist maintenance includes this). Use a high-quality lubricant suitable for chains and gears.
- Storage: When not in use, store the hoist in a dry, clean environment to prevent rust and damage. The provided carrying bag is ideal for protection.
- Professional Servicing: For any significant repairs or if you suspect internal damage, consult a qualified professional or the manufacturer. Do not attempt complex repairs yourself unless you are certified.
8. Troubleshooting
This section addresses common issues you might encounter with your hand chain hoist.
| Problem | Possible Cause | Solution |
|---|---|---|
| Hoist not lifting/lowering smoothly | Kinked or twisted load chain; insufficient lubrication; internal mechanism obstruction. | Check and untwist the load chain. Apply appropriate lubricant to the chain and inspect for foreign objects. If issue persists, professional inspection may be needed. |
| Load slips or does not hold | Brake mechanism wear or malfunction; overloading. | Immediately lower the load safely. Do not use the hoist. This indicates a serious safety issue with the brake. Contact manufacturer or qualified service personnel. Ensure you are not exceeding the rated capacity. |
| Hand chain is difficult to pull | Overloading; lack of lubrication; internal friction. | Verify the load does not exceed the rated capacity. Lubricate the hand chain and internal components. If resistance continues, inspect for internal damage or wear. |
| Hooks or chain appear damaged | Wear and tear; improper use; overloading. | Do not use the hoist. Damaged hooks or chains are a severe safety hazard. Replace damaged components with genuine manufacturer parts or consult a professional for repair. |
If you encounter problems not listed here or if solutions do not resolve the issue, discontinue use immediately and contact YATOINTO customer support or a certified service technician.
