- Safety First: Always read and understand the instructions before use. Wear appropriate protective gear such as substantial footwear and long trousers. Inspect the mowing area for foreign objects and ensure bystanders maintain a safe distance. Never operate the machine barefoot or in open sandals.
- Operation: Do not operate in rain or wet conditions. Keep hands and feet away from rotating parts. Switch off and remove the isolator key before adjusting, cleaning, or leaving the machine unattended. Wait for all components to stop before touching. Avoid mowing on steep slopes and always walk, never run.
- Battery Handling: Only use the supplied Bosch battery charger indoors. Keep chargers and batteries away from moisture. Recharge batteries only with the specified charger. Do not charge other batteries. Store batteries in a cool, dry place, away from metal objects.
- Maintenance: Regularly inspect the machine and its parts for wear or damage. Keep nuts and bolts tight. Check the grass catcher for wear. Ensure replacement parts are of the correct type and approved by Bosch.
