Safety Information
Always prioritize safety when using any ladder. Failure to follow these instructions may result in serious injury or property damage.
- Inspect Before Use: Before each use, check the ladder for any damage, loose parts, or wear. Do not use if damaged.
- Stable Surface: Always place the ladder on a firm, level, and non-slippery surface. Ensure all four feet are in full contact with the ground.
- Weight Capacity: Do not exceed the maximum load capacity of 800 lbs (approximately 363 kg). This includes the user and any tools or materials.
- Maintain Balance: Always face the ladder when climbing up or down. Maintain three points of contact (two hands and one foot, or two feet and one hand) at all times.
- Do Not Overreach: Keep your body centered between the side rails. Do not overreach to the sides, as this can cause the ladder to tip.
- Top Step: Do not stand on the top step or the handrail. The top step is not designed for standing.
- Children and Pets: Keep children and pets away from the ladder during use.
- Electrical Hazards: Avoid using the ladder near electrical wires or equipment. Metal conducts electricity.
- Folding Mechanism: Ensure the safety buckle is engaged when the ladder is open and locked when folded. Keep fingers clear of pinch points during folding and unfolding.
Setup and Unfolding
The DUMOS 3-Step Foldable Step Ladder is designed for quick and easy setup.
- Positioning: Place the folded ladder on a flat, stable surface.
- Unfolding: Hold the top handrail firmly. Gently pull the front and back sections of the ladder apart until they are fully extended.
- Secure Mechanism: Ensure the metal safety buckle automatically locks into place. This confirms the ladder is securely open and ready for use.
- Stability Check: Before climbing, gently push on the sides of the ladder to ensure it is stable and does not wobble.

- Climbing: Climb one step at a time, using the comfortable handrail for support.
- Foot Placement: Place your feet fully on the wide, anti-slip pedals. The textured surface provides secure footing.

Maintenance
Proper maintenance ensures the longevity and safety of your ladder.
- Cleaning: Wipe the ladder clean with a damp cloth. Avoid abrasive cleaners that could damage the finish or anti-slip surfaces.
- Storage: Fold the ladder to its compact size and store it in a dry, safe place away from direct sunlight and extreme temperatures. Its slim profile allows for storage in tight spaces like closets or behind doors.
- Lubrication: Periodically check and lubricate moving parts (hinges, safety buckle) with a light oil to ensure smooth operation.

Troubleshooting
If you encounter issues with your DUMOS step ladder, refer to the following common problems and solutions:
- Ladder feels unstable: Ensure the ladder is placed on a completely flat and firm surface. Check that the safety buckle is fully engaged and all feet are making contact with the ground.
- Difficulty folding/unfolding: Check for any obstructions in the hinge mechanisms. Apply a small amount of lubricant to the hinges if they are stiff. Ensure the safety buckle is disengaged before folding.
- Steps feel slippery: Clean the anti-slip pedal surfaces to remove any dirt, dust, or grease. Ensure your footwear has good grip.
