WARNING: Failure to follow these safety instructions may result in serious injury or death.

5. Operating Instructions

To ensure safe operation of your step ladder, adhere to the following guidelines:

• Always maintain a firm grip on the handrails or side rails while climbing or descending.
• When working, keep your body centered between the side rails. Avoid leaning too far to one side, which can cause the ladder to tip.
• Use the ladder only for its intended purpose: providing elevated access for tasks. Do not use it as a bridge, scaffold, or for any other unintended application.
• Ensure the area around the base of the ladder is clear of obstructions.
• Never attempt to adjust or move the ladder while someone is on it.
• Descend the ladder slowly and carefully, maintaining control.

6. Maintenance

Regular maintenance will extend the life of your ladder and ensure its continued safe operation.

• Pre-Use Inspection: Before each use, visually inspect the entire ladder. Check for:
  • Bent, cracked, or broken side rails, treads, or platform.
  • Loose or missing rivets, bolts, or other fasteners.
  • Worn, damaged, or missing anti-slip feet.
  • Damage to the locking mechanism or spreaders.
  • Any signs of corrosion or material fatigue.
  If any damage is found, do not use the ladder.
• Cleaning: Clean the ladder regularly with a damp cloth and mild soap or detergent. Rinse thoroughly and dry completely. Avoid using abrasive cleaners, solvents, or harsh chemicals that could damage the materials.
• Storage: Store the ladder in a clean, dry place, away from direct sunlight, moisture, and extreme temperatures. Store it in its folded position to protect components and save space.
• Repairs: Do not attempt to repair damaged parts yourself. Contact qualified personnel or the manufacturer for repairs or replacement parts.

7. Troubleshooting

If you encounter any issues with your Mac Allister Step Ladder, refer to the following common problems and solutions:

• Ladder feels unstable or wobbly:

  • Check if the anti-slip feet are worn or missing. Replace if necessary.
• Difficulty unfolding or folding:
  • Check for any obstructions or debris in the hinges or locking mechanisms.

• Slipping during use:
