Opsætning og drift

1. Inspektion før brug

Before each use, inspect the ladder for any damage, loose parts, or missing components. Ensure all rungs, rails, and locking mechanisms are in good working order. Verify that the rope and pulley system (if applicable) operates smoothly and is free from fraying or tangles.

2. Positioning the Ladder

• Place the ladder on a firm, level surface. Avoid soft ground, uneven terrain, or slippery surfaces.
• Ensure the ladder's feet are properly engaged with the ground. Utilize the Shu-Lok feature to adjust the shoe position for optimal grip.
• Maintain a safe angle: For every four feet of ladder height, the base should be one foot away from the wall or support structure.
• Ensure the top of the ladder extends at least three feet above the landing surface.

3. Extending the Ladder

For models 20 feet and larger, use the integrated rope and pulley system to extend the fly section. Pull the rope steadily to raise the upper section to the desired height. Ensure the spring-loaded gravity locks fully engage the rungs before climbing. Verify both locks are securely in place.

4. Retracting the Ladder

To retract, slightly extend the ladder to disengage the gravity locks, then carefully lower the fly section using the rope. Ensure hands and fingers are clear of moving parts to prevent pinching.

5. Safe Climbing Practices

• Vend altid mod stigen, når du stiger op eller ned.
• Maintain three points of contact (two hands and one foot, or two feet and one hand) at all times.
• Do not overreach; reposition the ladder as needed.
• Ensure only one person is on the ladder at a time.
• Do not use the ladder near electrical wires or in stormy conditions.

Opretholdelse

Regular maintenance ensures the longevity and safe operation of your Werner extension ladder.

• Rensning: Clean the ladder regularly with mild soap and water. Avoid harsh detergents or abrasive cleaners that could damage the aluminum finish or safety labels.
• Smøring: Periodically lubricate moving parts such as the pulley system and gravity locks with a silicone-based lubricant to ensure smooth operation.
• Opbevaring: Store the ladder in a dry, protected area, away from extreme temperatures and direct sunlight. Store horizontally on racks or vertically against a wall to prevent warping or damage.
• Rebinspektion: Regularly check the rope for any signs of wear, fraying, or damage. Replace the rope immediately if any damage is observed.

Fejlfinding

This section addresses common issues you might encounter with your extension ladder.

• Ladder Not Extending/Retracting Smoothly:
  • Check for obstructions in the rail channels.
  • Ensure the rope is not tangled or frayed.
  • Lubricate the pulley system and glides.
• Gravity Locks Not Engaging:
  • Ensure the ladder is fully extended to the next rung.
  • Check for debris or damage preventing the locks from seating properly.
  • Lubricate the lock mechanisms.
• Ladder Instability:
  • Verify the ladder is placed on a firm, level surface.
