Please read this manual thoroughly before using the product to ensure proper understanding of its functions, limitations, and safety requirements.
2. Important Safety Information
WARNING: Failure to follow these instructions and warnings may result in serious injury or death. This equipment must only be used by trained and competent persons.
- Always inspect the lifeline and all connecting components before each use. Do not use if any damage, wear, or malfunction is observed.
- Ensure the anchor point is capable of supporting the intended load and meets all applicable safety standards.
- Connect the lifeline securely to a full-body harness and an approved anchor point.
- Maintain a clear fall path below the working area. Be aware of potential obstructions.
- Do not modify the lifeline or any of its components.
- The maximum rated weight capacity for this device is 310 lbs (including tools and clothing).
- In the event of a fall, immediately remove the lifeline from service and have it inspected by a qualified person or manufacturer.
- Store the lifeline in a clean, dry place away from direct sunlight, chemicals, and extreme temperatures.
3. Product Components
The Lonsge 30FT Self-Retracting Lifeline consists of several key components designed for optimal fall protection:
- Galvanized Steel Cable: A 30 ft cable braided with 6 strands of 222 galvanized steel wire rope, 1/5-inch diameter, offering superior smoothness and abrasion resistance.
- Self-Retracting Mechanism: Allows the cable to automatically retract or extend, maintaining constant tension and reducing slack.
- Internal Shock Absorber: Features four independent internal locks that quickly brake and lock in a fall event, reducing impact forces. Maximum braking distance: 54 inches. Average braking force: 900 lbs.
- Locking Buckle (Swivel Eye Anchor): Located at the bottom of the wire rope, it supports 360° rotation to prevent tangling and includes an automatic locking function with a gate strength of 5,000 lbs.
- High-Strength Reinforced Polymer Shell: A lightweight and durable housing that protects the internal components from water, drops, high temperatures, and corrosion.
- Top Latch Swivel: For secure attachment to an anchor point.

4. Setup and Installation
Proper setup is crucial for effective fall protection. Follow these steps carefully:
- Inspect the Lifeline: Before each use, visually inspect the entire lifeline, including the housing, cable, carabiners, and shock absorber. Look for cuts, fraying, corrosion, deformation, or any other signs of damage or wear. Ensure all locking mechanisms operate smoothly.
- Select an Anchor Point: Choose an anchor point that is structurally sound and capable of supporting a minimum of 5,000 lbs (22.2 kN) per worker attached, or meets the requirements of a qualified person. The anchor point should be located directly above the work area whenever possible to minimize swing fall hazards.
- Attach to Anchor Point: Connect the top latch swivel of the lifeline to the selected anchor point. Ensure the carabiner gate is fully closed and locked.
- Attach to Harness: Connect the self-locking hook (swivel eye anchor) at the end of the lifeline's cable to the dorsal D-ring of your full-body harness. Verify that the hook is fully closed and locked.
- Verify Connections: Double-check all connections to ensure they are secure and properly engaged. Perform a gentle tug test on the lifeline to confirm it is firmly attached to both the anchor and your harness.

5. Operating Instructions
The Lonsge Self-Retracting Lifeline is designed for ease of movement while providing continuous fall protection.
- Movement: As you move, the lifeline's cable will automatically extend and retract, maintaining slight tension. This prevents slack and reduces the risk of tripping.
- Fall Arrest: In the event of a fall, the internal locking mechanism will engage rapidly, arresting the fall. The integrated shock absorber will deploy to dissipate energy and reduce the force exerted on the user.
- Swivel Function: The 360° rotating locking buckle helps prevent the cable from twisting or tangling during movement, enhancing user comfort and safety.

6. Maintenance and Storage
Regular maintenance and proper storage extend the lifespan of your lifeline and ensure its continued reliability.
- Cleaning: Clean the lifeline with a damp cloth and mild soap. Rinse thoroughly with clean water and allow it to air dry completely before storage. Do not use harsh chemicals or solvents.
- Inspection: In addition to pre-use inspections, a thorough inspection by a competent person should be performed at least annually, or more frequently depending on usage and environmental conditions. Document all inspections.
- Storage: Store the lifeline in a cool, dry, and clean environment, away from direct sunlight, corrosive substances, sharp objects, and extreme temperatures. Ensure the cable is fully retracted before storage.
- Post-Fall Protocol: If the lifeline has been subjected to a fall arrest, it must be immediately removed from service and either destroyed or returned to the manufacturer for inspection and recertification. Do not reuse a lifeline that has arrested a fall without professional evaluation.
7. Troubleshooting
If you encounter issues with your Lonsge Self-Retracting Lifeline, consider the following:
- Cable Not Retracting Smoothly:
- Check for any debris or obstructions in the cable path or around the housing opening.
- Ensure the cable is not twisted or kinked.
- Clean the cable and housing as per maintenance instructions.
- If the issue persists, remove from service and contact customer support.
- Locking Mechanism Not Engaging/Disengaging:
- Verify that the carabiner gates are not obstructed and move freely.
- Ensure the self-locking hook is not jammed.
- Do not force any mechanism. If it does not operate correctly, remove the unit from service immediately.
- Visible Damage or Wear: Any visible damage to the housing, cable, or connectors requires immediate removal from service. Do not attempt repairs.
