1. Check and replace the cutting blades

• Check the blades for wear, damage or deformation.
• Blunt or damaged blades leave an uneven cut pattern.
• Replace all blades at the same time – including screws and washers.
• Recommendation: replace every 3 months or after 150 operating hours.

2. Clean the cutting disc and underside

• Remove grass clippings and deposits from the cutting disc and underside.
• Clogged cutting discs significantly reduce cutting performance.
• Wear protective gloves when cleaning.

3. Adjust the cutting height

• Check whether the set cutting height is suitable for the current lawn condition.
• For very long grass: increase the cutting height and plan several passes.
• Recommendation: do not cut more than one third of the grass height per pass.

4. Check the mowing schedule and mode

• Check in the Mammotion app whether the mowing schedule is correctly configured.
• Choose a suitable mowing mode for your terrain.
• Make sure all areas of the lawn are included in the task area.

5. In wet grass

• Wet grass sticks to the blades and underside and impairs performance.
• Plan mowing sessions in dry weather where possible.
• Clean the robot thoroughly after mowing in wet conditions.

6. Check for motor overheating

• Error code 316 or 326 in the app indicates overheating of the cutting disc motor.
• Allow the robot to cool down – it will automatically resume operation.

When to contact customer service?

• Mowing performance remains poor after blade replacement and cleaning.
• The cutting disc motor repeatedly shows error codes (316, 318, 323, 325, 326).
