Setup
1. Pedal Installation
- Identify the left (L) and right (R) pedals. The left pedal has a reverse thread.
- Apply a small amount of grease to the pedal threads.
- Thread the right pedal (R) clockwise into the right crank arm.
- Thread the left pedal (L) counter-clockwise into the left crank arm.
- Tighten both pedals securely using a 15mm pedal wrench or an 8mm hex key (for the spindle end) to a torque of 35-55 N·m (26-40 ft·lbs).

2. Cleat Installation and Adjustment
Install the SM-SH51 cleats onto your SPD-compatible cycling shoes. The cleats allow for fore-aft and rotational adjustment to optimize pedaling efficiency and comfort. Ensure the cleats are positioned correctly for your foot and securely tightened.
Cleat Tension Adjustment
The release tension of the binding mechanism can be adjusted to suit individual preference and riding style. This is crucial for safe and comfortable use.
- Locate the tension adjustment screw on the rear of each pedal binding.
- Use a 2.5mm hex key to turn the screw.
- Turn the screw clockwise (+) to increase tension (harder to release).
- Turn the screw counter-clockwise (-) to decrease tension (easier to release).
- Ensure the tension is set equally on both pedals for consistent release.

Operating the Pedals
Clipping In
To engage your foot with the pedal:
- Position the front of your shoe's cleat over the front hook of the pedal binding.
- Press down firmly with your heel to engage the rear of the cleat into the pedal binding. You should hear a distinct click.
- Ensure your foot is securely clipped in before beginning to pedal.

Clipping Out
To disengage your foot from the pedal:
- Twist your heel outward away from the bicycle.
- Continue twisting until the cleat releases from the pedal binding.
- Practice this motion repeatedly to develop muscle memory, especially for emergency stops.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your pedals.
- Cleaning: The PD-M520 features an open binding design for superior mud-shedding. After riding in muddy or dusty conditions, clean the pedals and cleats with water and a brush to remove debris. Allow to dry thoroughly.
- Lubrication: The pedals feature a sealed bearing cartridge axle, which requires minimal maintenance. However, periodically apply a small amount of light grease to the pedal spindle threads and the cleat contact points on the pedal binding to ensure smooth operation and prevent corrosion.
- Inspection: Regularly check the pedals and cleats for signs of wear, cracks, or damage. Ensure all screws (cleat screws, tension adjustment screws) are tight. Replace worn cleats or damaged pedals immediately.
