What is the recommended lawn size for this mower?
This mower is ideal for medium to larger-sized lawns, typically up to around 500 square meters, depending on battery capacity and grass conditions.
How do I adjust the cutting height?

What is the capacity of the grass bag?
The mower is equipped with a 40-litre fabric grass bag, which includes an integrated indicator to show when it is full.
Is the battery system compatible with other brands?
Yes, the 18V POWER FOR ALL battery system is compatible with tools from Bosch and other partner brands within the POWER FOR ALL alliance.
How long will the batteries last?
Runtime depends on the capacity of the 18V batteries used (Ah rating), the type and length of grass, and the selected cutting height. Bosch Syneon Technology optimizes runtime for each use.
What maintenance is required for the blades?
It is recommended to regularly inspect the cutting blades for sharpness and damage. For optimal performance, dull or damaged blades should be sharpened or replaced.
Troubleshooting
Mower does not start
Ensure two fully charged 18V batteries are correctly inserted. Check that the safety lever is engaged and the start button is pressed. Verify the battery compartment cover is securely closed.
Uneven cutting performance
Check if the cutting height is set correctly. Inspect the cutting blade for damage or dullness and replace or sharpen if necessary. Ensure the grass bag is not overfilled, as this can affect airflow and cutting.
Mower stops during operation
This could be due to an overheating motor or low battery power. Allow the mower to cool down if it feels excessively hot. Ensure batteries are adequately charged. Check for any blockages around the blade or in the grass chute.
Grass clippings not being collected effectively
Empty the grass bag. Ensure the grass chute is not clogged. Make sure the cutting height is not set too low for the current grass length, which can cause clippings to be blown away rather than collected.
