2. Important Safety Warnings

• EN131 Approved: This ladder meets EN131 safety standards.
• Maximum Load Capacity: Do not exceed the maximum load capacity of 330 pounds (150 kg).
• Secure Locking: Always ensure all locking mechanisms on each rung are fully engaged and clicked into place before climbing. Failure to do so can result in serious injury.
• Stable Surface: Use the ladder only on firm, level, and non-slippery ground.
• Finger Safety: Exercise extreme caution when extending or collapsing the ladder. Keep hands and fingers clear of rungs and locking mechanisms to prevent pinching.
• Two-Person Operation: Due to its weight (43 lbs) and size, two people are recommended for safe carrying and initial setup, especially when extending to full height.
• Angle for Straight Ladder: When used as a straight ladder, ensure it is set up at approximately a 75-degree angle to the wall or support surface.
• No Overreaching: Maintain your center of gravity between the side rails. Do not overreach.
• Electrical Hazards: Keep the ladder away from electrical wires or power sources. Aluminum conducts electricity.

5. Operating the Ladder

5.1 Extending the Ladder

1. Place the ladder on a firm, level surface.
2. Starting from the top rung, pull each section upwards one by one until it fully extends and the locking mechanisms click into place.
3. Visually confirm that all black locking tabs are fully engaged on both sides of each extended rung.

5.3 Straight Ladder Configuration

1. Ensure the ladder is in its folded, compact state.
2. Release the hinge lock to a free position.
3. Unfold the ladder completely to 180 degrees until the hinge locks click into place, forming a straight line.
4. Extend all rungs one by one, ensuring each locks securely.
5. Lean the ladder against a stable surface, ensuring the angle with the ground is close to 75 degrees for optimal stability.

5.4 Collapsing the Ladder

1. Always start collapsing the ladder from the bottom rung upwards.
2. On each rung, push the two black locking tabs inwards simultaneously to unlock the section.
3. Slowly lower the rung, ensuring your hands and fingers are completely clear of the collapsing sections to prevent pinching.
4. Continue this process for each rung until the ladder is fully collapsed.
5. Secure the collapsed ladder with the provided strap for easy transport and storage.

6. Maintenance

• Cleaning: Keep the ladder clean from dirt, paint, and debris. Use a damp cloth to wipe down aluminum surfaces.
• Inspection: Regularly inspect all rungs, locking mechanisms, stabilizer bars, and anti-slip feet for any signs of damage or wear before each use.
• Lubrication: Periodically apply a silicone-based lubricant to the moving parts of the locking mechanisms to ensure smooth operation.
• Storage: Store the ladder in a dry, cool place, away from direct sunlight and extreme temperatures. Ensure it is fully collapsed and secured with the strap.

7. Troubleshooting

• Rungs Not Locking: If a rung does not lock into place, ensure it is pulled up completely until a distinct click is heard. Check for any obstructions in the locking mechanism. Do not use the ladder if any rung fails to lock securely.
• Ladder Instability: Verify that all extended rungs are locked, the hinge joints are fully engaged (for A-frame or straight configurations), and the ladder is placed on a firm, level surface. Ensure stabilizer bars are properly installed and tightened.
• Difficulty Collapsing: Ensure both locking tabs on the rung you are attempting to collapse are fully pushed inwards. If a rung is stuck, gently wiggle it while pressing the tabs. Never force a rung down.
• Damaged Parts: If any part of the ladder is damaged, do not use it. Contact NUNET customer support for replacement parts or professional repair advice.
