Introduction
This manual provides essential instructions for the safe and effective use of your Werner MT-26 Telescoping Multi-Ladder. The MT-26 is a versatile aluminum ladder designed for various applications, functioning as a twin stepladder, extension ladder, stairway ladder, or two scaffold bases. It features a 300-pound duty rating per side when used as a stepladder, accommodating two users simultaneously. Please read this manual thoroughly before operation.

Safety Information
Always prioritize safety when using any ladder. Failure to follow these instructions may result in serious injury or death. This ladder meets ANSI and OSHA standards.
- Inspect Before Each Use: Ensure all parts are in good working order, including hinges, locks, steps, and feet. Do not use if damaged.
- Stable Surface: Always place the ladder on a firm, level, and non-slippery surface.
- Proper Angle: When used as an extension ladder, maintain a 4-to-1 ratio (for every four feet of ladder height, the base should be one foot away from the wall).
- Load Capacity: Do not exceed the 300-pound duty rating (combined weight of user and materials). When used as a twin stepladder, each side supports 300 pounds.
- Electrical Hazards: This aluminum ladder conducts electricity. Avoid contact with live electrical wires or equipment.
- Finger Safety: Exercise extreme caution when adjusting or folding the ladder to prevent pinching fingers in moving parts.
- Maintain Three Points of Contact: Always maintain three points of contact (two hands and one foot, or two feet and one hand) when climbing or descending.
- Do Not Overreach: Keep your body centered between the side rails.
Setup and Configuration
The Werner MT-26 offers multiple configurations for various tasks. Always ensure the ladder is fully locked in the desired position before use.
1. Opening and Closing the Ladder
- To open or close the ladder, locate the push-knob locking hinges on the sides.
- Push the knobs inward to disengage the lock.
- Carefully rotate the ladder sections to the desired position (e.g., from folded to A-frame).
- Release the knobs and ensure they snap back into place, securely locking the sections.

2. Height Adjustment (Telescoping Sections)
- To adjust the height of the ladder, locate the spring-loaded J-locks on the inner sections.
- Pull the J-locks outward to disengage them.
- Carefully extend or retract the inner sections to the desired height, in one-foot increments.
- Ensure the J-locks fully re-engage into the corresponding holes, securing the sections at the new height. Verify both sides are locked before use.
3. Configuring for Use
The MT-26 can be configured into several modes:
- Twin Stepladder: Fold the ladder into an 'A' shape. Ensure both sides are equally extended and locked.
- Extension Ladder: Fully extend the ladder sections and lock them straight. Lean against a stable surface at the correct angle.
- Stairway Ladder: Adjust each side of the A-frame independently using the J-locks to accommodate uneven surfaces like stairs.
- Scaffold Bases: The ladder can be separated into two individual bases to support a plank (plank not included). Refer to the detailed instructions for this configuration.

Operating Instructions
Once the ladder is correctly set up and locked in the desired configuration, follow these guidelines for safe operation:
- Climbing: Always face the ladder when climbing or descending. Use both hands to grip the side rails.
- Working Height: Do not stand on the top two steps of a stepladder or the top three steps of an extension ladder.
- Stability: The extra-wide flared bottom provides firm support. Ensure the ladder feet are fully in contact with the ground.
- Movement: Never move a ladder while someone is on it.
- Weight Distribution: Distribute your weight evenly and avoid sudden movements.
Maintenance
Regular maintenance ensures the longevity and safe operation of your Werner MT-26 Multi-Ladder.
- Cleaning: Clean the ladder regularly with a damp cloth to remove dirt, grease, or other debris. Avoid harsh chemicals that could damage the aluminum or plastic components.
- Inspection: Before and after each use, inspect all components for wear, damage, or loose parts. Pay close attention to:
- Hinges and locking mechanisms (push-knobs, J-locks)
- Steps (double-riveted for durability)
- Side rails (smooth curved rails)
- Heavy-duty non-marring feet
- Lubrication: Periodically apply a silicone-based lubricant to the moving parts of the hinges and J-locks to ensure smooth operation.
- Storage: Store the ladder in a dry, protected area, away from extreme temperatures and direct sunlight. The telescoping design allows it to be shrunk down and folded for compact storage.
Troubleshooting
Here are some common observations and potential solutions:
- Difficulty Adjusting Height or Folding:
- Ensure J-locks and push-knobs are fully disengaged.
- Check for dirt or debris obstructing the mechanisms. Clean and lubricate if necessary.
- Verify that the ladder sections are aligned correctly.
- Ladder Feels Heavy:
- The MT-26 is constructed from durable aluminum and weighs approximately 59.3 pounds. This weight contributes to its stability and 300-pound duty rating.
- For extension ladder setup, it may be easier to extend the top section first, stand the ladder vertically, and then extend the bottom section. For full extension, two people may be required to safely raise the ladder.
- Noticeable Flex When Extended:
- Some flex is inherent in multi-position ladders, especially when fully extended. The design accounts for this. Ensure all locking mechanisms are fully engaged and the ladder is placed on a stable surface.
- J-Hooks or Push-Knobs Damaged:
- These components are critical for safety. If any part of the locking mechanism is damaged, discontinue use immediately and contact Werner customer support for replacement parts or service.
