This manual provides essential information for the safe and efficient operation of the Bosch AdvancedRotak electric lawnmower series (650-790). Always read the full safety instructions before use.
Safety Notes
Warning: Keep bystanders at a safe distance. Be aware of sharp rotating blades; never touch them while they are moving. Always disconnect the power plug before performing any adjustments, cleaning, or if the cable becomes entangled.
Operation
Before starting, ensure the handle is unfolded and the working height is adjusted. Connect the extension lead securely. Always mow in daylight or good artificial light. Avoid mowing in wet grass or during bad weather conditions, especially if there is a risk of lightning.


Leaf Collection
The leaf collect blade is designed to pick up autumn leaves. For optimal results, set the cutting height to 70 mm and ensure the area is clear of foreign objects like stones, sticks, or glass.
Maintenance
Always wear gardening gloves when handling or working near the sharp blades. Regularly check that all nuts, bolts, and screws are tight to ensure safe working conditions. Keep the machine clean and free from debris before storage.

Troubleshooting
If the motor refuses to start, check the power supply, the fuse, and ensure the grass is not too long (max 30cm). If the machine vibrates excessively, check if the blade nut/bolt is loose and tighten to 17 Nm.
