Preparation and Safety Guidelines

Tools Needed
  • Screwdriver
Safety Guidelines
  • Always disconnect the piano from the power source before starting any adjustments. Electricity can be dangerous!
  • Work slowly and carefully. Forcing parts can cause damage to the piano's mechanism.
  • If you are unsure about any step, consult a qualified piano technician. Improper adjustments can lead to irreparable damage.

Step-by-Step Instructions

  1. Inspection and Preparation

    • Identify and assess the slop in the piano pedals.
    • Check for any cracks or damage in the piano pans and address if needed.
    • Clean the pedals to remove built-up wax and dirt using brillo pads.

  2. Pedal Adjustment

    • Loosen the top screw of the affected pedal.
    • Tighten the bottom screw to adjust the petal's position, ensuring it's centered and not overly tight.
    • Repeat steps 2-4 for other pedals as needed, using a quarter to half turn for adjustment.
    • Re-tighten the top screw about half a turn.

  3. Maintenance and Refinement

    • Apply a drop of lubricating oil to maintain smooth movement.
    • Check for playability; the pedal should move easily with one finger.
    • Check the rod and tighten the fixture if loose to ensure proper pedal seating.
    • Add felt to the slots of the pedals to enhance movement if needed. This often requires removing the pedals.

Tips

  • Only snug the screws; avoid over-tightening to prevent damage.
  • Maintain proper spacing between the wires for optimal sound.
  • Use brillo pads for cleaning to avoid deep scratches.

Common Mistakes to Avoid

1. Over-tightening Pedal Screws

Reason: Excessive tightening can strip the screw threads or damage the pedal mechanism.
Solution: Tighten screws firmly but gently, stopping when resistance is felt.

2. Ignoring Pedal Alignment

Reason: Misaligned pedals can cause uneven response or hinder smooth playing.
Solution: Ensure the pedal is straight and centered, adjusting the mounting screws as needed.

3. Improper Lubrication

Reason: Using the wrong lubricant or applying too much can attract dust and grit, leading to sticking pedals.
Solution: Use a small amount of high-quality piano lubricant, focusing on moving parts and avoiding excessive application.

FAQs

My piano pedal feels stiff or unresponsive. What's the most likely cause?
Stiffness or unresponsiveness often stems from accumulated dust, grime, or a lack of lubrication in the pedal mechanism. Worn-out felt or other parts can also contribute. Check for obstructions and consider applying a small amount of appropriate lubricant (like silicone-based lubricant) to moving parts, but only after carefully examining the mechanism to identify the source of the problem.
