How to Fix / Troubleshooting

Safety first: Do not lift or tilt the mower while blades are spinning. Always wait until blades stop completely before handling.

  • Test safety response: On a flat surface, start the mower and then press the emergency stop. Measure how long blades take to stop. Compare with Cedrus specifications.
  • Check lift sensor: Gently lift the mower's front while observing blade behavior. Blades should stop quickly. If not, the lift sensor may be slow or faulty.
  • Firmware update: Ensure the mower firmware is up to date, as safety timing may be improved in newer versions.
  • Service requirement: If blades consistently take too long to stop, discontinue use and have a Cedrus technician inspect the brake circuit and safety sensors.
