- Maintain three points of contact (two hands and one foot, or two feet and one hand) while climbing or descending.
- Do not overreach. Keep your body centered between the side rails.
- Do not exceed the maximum load capacity of 330 lbs (149.7 kg). This includes the user and any tools or materials.
- Avoid using the ladder in windy conditions or near electrical wires.
- Ensure the ladder is clean and free of oil, grease, or other slippery substances.

3. Product Components
The VEVOR Telescoping A-Frame Ladder consists of the following main components:
- Aluminum Alloy Frame: Lightweight yet durable construction.
- Telescoping Rungs: Extendable sections for adjustable height.
- Locking Mechanisms: Secure each rung in place during extension and retraction.
- Adjustable Locking Key: Allows for angle adjustment between A-frame and straight configurations.
- Anti-Slip Foot Pads: Provide stability and prevent sliding on various surfaces.
- Transport Wheels: Located at the base for easy portability.
4. Setup and Configuration
4.1. Unfolding the Ladder
- Place the folded ladder on a flat, stable surface.
- Carefully extend the ladder sections one by one from the bottom, ensuring each rung's locking mechanism clicks into place.
- To form the A-frame, open the two sides of the ladder until the central hinge locks securely.
4.2. Adjusting Height and Configuration
The ladder can be configured as an A-frame or a straight extension ladder. The adjustable locking key allows for angle adjustments up to 180 degrees.
- To Extend Rungs: Pull the locking buttons outwards on both sides of a rung, then extend the section upwards. Release the buttons to lock the rung in the desired position. Ensure both buttons are fully engaged. Repeat for each section.
- To Retract Rungs: Pull the locking buttons outwards on both sides of a rung, then gently push the section downwards. Release the buttons. Retract from the top down.
- To Change Angle (A-frame to Straight): Locate the adjustable locking key at the hinge. Unscrew the locking key on one side, adjust the ladder to the desired angle (e.g., 180 degrees for a straight ladder), and then re-secure the locking key. Ensure it is fully tightened before use.

6. Maintenance
- Cleaning: Clean the ladder regularly with a damp cloth and mild detergent. Avoid abrasive cleaners or solvents that could damage the aluminum or plastic components.
- Inspection: Periodically inspect all parts for wear, damage, or loose fasteners. Pay close attention to rungs, locking mechanisms, foot pads, and hinges.
- Lubrication: Apply a silicone-based lubricant to the telescoping mechanisms and locking pins if they become stiff. Do not over-lubricate, as this can attract dirt.
- Storage: Store the ladder in a dry, protected area, away from extreme temperatures and direct sunlight. Ensure it is fully retracted and secured to prevent accidental opening.

7. Troubleshooting
- Ladder sections not extending/retracting smoothly: Clean the sections and apply a silicone lubricant. Ensure no debris is obstructing the mechanism.
- Locking mechanisms not engaging: Check for dirt or damage. Ensure the buttons are fully released after extending/retracting. Do not force the mechanism.
- Ladder feels unstable: Verify that all rungs are fully locked and the ladder is placed on a firm, level surface. Check foot pads for wear.
