Robot mower shows E008 and shuts down; often after long use or in hot weather.

Safety first: Move the mower to a shaded, well-ventilated area and turn OFF the main power switch.

• Allow cooling: Let the mower sit powered off for at least 30–45 minutes to cool internal components.
• Inspect cooling vents: Check the top and side vents for grass, dust, or debris. Clean gently with a soft brush or compressed air (short bursts, from a distance).
• Check mowing conditions: Avoid mowing in direct midday sun on very hot days. Schedule mowing for early morning or evening.
• Reduce load: If grass is very tall or wet, raise the cutting height and mow more frequently to reduce motor load.
• Restart: After cooling and cleaning, power ON and resume operation.

Repeated E008 in moderate temperatures may indicate a failing motor, temperature sensor, or internal fan. Professional diagnosis is recommended.
