Product Overview
Made from high quality Aluminum alloys, the Telesteps 12ES multi-function telescoping ladder can be used as an extension ladder, a step ladder, and also on stairs or uneven surfaces. This telescoping combination ladder features fully automatic extension and retraction with a patented one-touch release mechanism for ease of use. It is easy to use, easy to carry, and easy to store.
Key features include:
- Compact 8 ft A-Frame Stepladder: Delivers 12 ft reach with pro-grade stability — perfect for indoor installs, staircases, and outdoor maintenance where space is tight.
- Heavy-Duty Type 1AA Rating: Supports up to 375 lbs with aircraft-grade aluminum construction — built for tools, gear, and jobsite use.
- One-Touch Retraction: Patented mechanism allows smooth, pinch-free opening and closing — folds down to 32 in. for easy storage in vans, closets, or service trucks.
- Safe & Level on Any Surface: Integrated stair offset and wide stabilizer bar offer secure footing on stairs, slopes, or slick surfaces.
- Visual Safety Lock Indicators: Rung windows provide clear confirmation when each step is locked and safe to climb.
Setup and Deployment
The Telesteps 12ES ladder is designed for quick and easy setup. Always ensure the ladder is placed on a firm, level surface before extending. For A-frame use, ensure both sides are fully extended and locked.
Extending the Ladder:
- Place the ladder on a stable, flat surface.
- Grasp the top rung of the ladder.
- Pull upwards to extend the sections. Each section will automatically lock into place with an audible click.
- Visually confirm that all safety lock indicators (rung windows) show green, indicating that each step is securely locked.
- For A-frame configuration, ensure both sides are extended equally and the hinges are securely locked.
Retracting the Ladder (One-Touch Release):
- Ensure no one is on the ladder and it is clear of obstructions.
- Locate the red release buttons on each side of the ladder, typically near the bottom sections.
- Press both red buttons simultaneously. The ladder sections will retract smoothly and automatically.
- Guide the ladder as it retracts to prevent rapid collapse and ensure proper stacking of sections.
- Secure the retracted ladder with the provided Velcro strap for easy carrying and storage.
Stair Offset Feature:
The Telesteps 12ES includes a stair offset feature for use on uneven surfaces or stairs. To activate:
- Partially extend the ladder.
- On one side of the ladder, locate the small block near the bottom.
- Adjust the height of one leg by engaging this block, allowing the ladder to be stable on different levels, such as stair steps.
Operating Instructions and Safety
Always prioritize safety when using the Telesteps 12ES ladder. Adhere to the following guidelines:
- Inspection: Before each use, inspect the ladder for any damage, loose parts, or obstructions. Ensure all locking mechanisms are clean and functioning correctly.
- Stable Surface: Always place the ladder on a firm, level, and non-slip surface. Use the stair offset feature for uneven terrain.
- Proper Angle: When using as an extension ladder, ensure it is set at approximately a 75-degree angle (for every 4 feet of ladder height, the base should be 1 foot away from the wall).
- Weight Capacity: Do not exceed the maximum load capacity of 375 lbs (Type 1AA duty rating). This includes the user, tools, and materials.
- Climbing: Always face the ladder when ascending or descending. Maintain three points of contact (two hands and one foot, or two feet and one hand) at all times.
- Top Rungs: The top two rungs are designed for leaning against or holding onto for stability, not for climbing or standing.
- Overreaching: Do not overreach. Keep your belt buckle (navel) between the side rails. If you cannot reach, descend and reposition the ladder.
- Electrical Hazards: Avoid using the ladder near electrical wires or equipment. Aluminum conducts electricity.
- Weather Conditions: Do not use the ladder in strong winds, storms, or on slippery surfaces due to ice, snow, or excessive moisture.
- Storage: Store the ladder in a clean, dry place away from extreme temperatures and direct sunlight.
Maintenance
Regular maintenance ensures the longevity and safe operation of your Telesteps 12ES ladder.
- Cleaning: Clean the ladder regularly with a damp cloth to remove dirt, grease, and debris. Avoid abrasive cleaners that could damage the aluminum finish.
- Lubrication: Periodically apply a silicone-based lubricant to the telescoping mechanisms and locking pins to ensure smooth operation. Do not over-lubricate, as this can attract dirt.
- Storage: Store the ladder in a dry, protected area to prevent corrosion and damage from environmental elements.
- Damage Check: If any part of the ladder is bent, cracked, or otherwise damaged, do not use it. Contact Telesteps customer support for repair or replacement parts.
- Feet/Pads: Check the condition of the rubber feet or anti-slip pads regularly. Replace them if they show signs of wear to maintain stability.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Ladder sections do not extend/retract smoothly. | Dirt or debris in the mechanism; lack of lubrication. | Clean the sections and apply a silicone-based lubricant. Ensure no foreign objects are lodged. |
| Safety lock indicators do not show green. | Section not fully extended and locked; debris preventing full engagement. | Ensure each section is pulled firmly until it clicks into place. Clear any debris from the locking mechanism. Do not use if indicators are not green. |
| Ladder feels unstable during use. | Uneven surface; worn anti-slip feet; improper setup. | Ensure the ladder is on a firm, level surface. Use the stair offset feature if needed. Check and replace worn anti-slip feet. Verify all sections are locked. |
| Difficulty pressing release buttons. | Mechanism is stiff; buttons are dirty. | Clean the buttons and surrounding area. Apply a small amount of lubricant if necessary. Ensure even pressure is applied to both buttons. |
