5. Setup
5.1 Mounting the Hoist
The hoist must be securely mounted to a robust overhead structure, such as a steel beam or reinforced concrete ceiling, capable of supporting at least twice the maximum rated load. Use the provided U-shaped mounting brackets, bolts, and washers.
- Identify a suitable mounting location that can safely bear the weight.
- Position the hoist and secure it using the two U-shaped brackets and bolts. Ensure the brackets are tightened firmly to prevent movement.
- For optimal stability, it is recommended to use a square or rectangular metal bar that fits within the inner dimensions of the mounting rings (44mm x 44mm) to fix the hoist.

5.2 Cable Configuration
The hoist can be configured for single-line or double-line lifting, affecting both lifting capacity and speed.
- Single-Cable Lifting: For loads up to 220 lbs (100 kg), attach the load directly to the main hook. This provides a lifting height of 38 ft and a speed of 33 ft/min.
- Double-Cable Lifting: For loads up to 440 lbs (200 kg), use the provided pulley block. Loop the wire rope through the pulley block and attach the pulley's hook to the load. Then, secure the end of the wire rope back to the hoist's main body. This configuration reduces the lifting height to 19 ft and the speed to 16 ft/min.

5.3 Emergency Stop Switch
The red emergency stop button on the remote control is normally locked in the original setting for safety. Before operation, rotate the red button clockwise to release it. The button will pop up, indicating the remote is ready for use. To engage the emergency stop, press the red button down until it locks. The hoist will not respond to up/down commands when the emergency stop is engaged.

5.4 Limit Switch
The hoist is equipped with an upper limit switch. This safety feature automatically powers off the hoist when the load reaches its maximum height, preventing over-lifting and potential damage. The metal rectangular part (up-limited frame) will contact the white limit switch, stopping operation. Ensure there is enough space for the limit switch to return to its position after activation. If needed, adjust the distance between the head and the switch.

6. Operating Instructions
Before operating, ensure the hoist is properly mounted, the cable is correctly configured (single or double line), and the emergency stop button is released.
- Connect Power: Plug the hoist into a standard 110V power outlet.
- Prepare Load: Securely attach the load to the hook(s) using appropriate lifting straps or chains. Ensure the load is balanced.
- Lift Load: Press and hold the "Up" button on the remote control to raise the load. Monitor the load and cable for any obstructions or issues.
- Lower Load: Press and hold the "Down" button on the remote control to lower the load. Control the descent carefully.
- Emergency Stop: In case of an emergency or malfunction, immediately press the red emergency stop button.
- Cable Management: When raising or lowering, guide the cable to ensure it spools evenly onto the drum. Uneven spooling can lead to tangles or damage.

7. Maintenance
Regular maintenance ensures the longevity and safe operation of your hoist.
- Daily Inspection: Before each use, visually inspect the hoist for any signs of damage, wear, or loose connections. Check the wire rope for kinks, fraying, or corrosion.
- Wire Rope: If the wire rope shows significant wear or damage, it must be replaced by a qualified technician. Do not attempt to repair a damaged wire rope.
- Motor: The hoist features a powerful copper motor designed for high conduction and energy saving, with good heat dissipation. Keep the motor area clean and free from debris to ensure proper cooling.
- Lubrication: Consult a professional for periodic lubrication of moving parts as required.
- Cleaning: Keep the hoist clean and dry. Do not use harsh chemicals or abrasive cleaners.

8. Troubleshooting
If you encounter issues with your hoist, refer to the following common problems and solutions:
- Hoist does not operate:
Possible Cause: Emergency stop button is engaged.
Solution: Rotate the red emergency stop button clockwise until it pops up. - Hoist stops during lifting/lowering:
Possible Cause: Upper limit switch activated.
Solution: Lower the load slightly to disengage the limit switch. Check for obstructions or adjust the limit switch position if necessary. - Reduced lifting capacity or speed:
Possible Cause: Hoist is configured for double-line lifting, or the load exceeds the rated capacity.
Solution: Verify the cable configuration. Ensure the load does not exceed the capacity for the current setup. - Wire rope tangles or spools unevenly:
Possible Cause: Lack of guidance during operation.
Solution: Always guide the wire rope by hand (wearing gloves) to ensure even spooling onto the drum. - Unusual noises or vibrations:
Possible Cause: Loose components, damaged motor, or worn parts.
Solution: Immediately stop operation. Inspect the hoist for loose bolts or visible damage. If the issue persists, contact customer support.
