Escalator Step Installation Instructions

1. Pre-Installation Safety & Preparation

• Cut off the escalator main power supply and hang a safety warning sign to prevent accidental startup.
• Prepare matching escalator steps, shaft pins, circlips, professional wrenches and safety protective gear.
• Inspect new steps for surface cracks, broken treads or deformed mounting holes; confirm model compatibility.
• Check step rollers and chain mounting holes for wear, jamming or damage before installation.

2. Dismantle the Old Step

• Move the target step to the maintenance access position by manual rotation.
• Remove the circlip and shaft pin that fix the step to the step chain.
• Detach the old step from the chain and guide track gently.
• Clean the chain mounting hole and check for deformation or severe abrasion.

3. New Step Installation

• Place the new step into the guide track, align the mounting holes with the step chain accurately.
• Insert the shaft pin through the step and chain hole completely.
• Install the circlip into the shaft groove for firm locking to prevent falling off during operation.
• Manually rotate the step to confirm flexible movement without shaking or jamming.

4. Position Adjustment & Inspection

• Adjust the step gap to ensure uniform spacing between adjacent steps.
• Check the engagement between step tread and comb plate, no scraping or collision.
• Manually drive the escalator for a full cycle operation to verify smooth running.

5. Test Run & Safety Notes

• Restore all covers and remove the safety warning sign after manual inspection.
• Power on and run the escalator with no load for 15 minutes, recheck step operation status.
• All installation work must be performed by certified professional technicians.
• Stop operation immediately if abnormal noise, jamming or step deviation occurs.
