FAQs

What is the runtime on a full charge?

Runtime varies depending on grass conditions, cutting height, and battery capacity. Refer to the product manual for estimated runtimes with specific battery sizes.

Can I use other brands' 18V batteries?

This system uses Bosch 18V POWER FOR ALL batteries. While compatible with other brands within the POWER FOR ALL ALLIANCE, it is recommended to use genuine Bosch batteries for optimal performance and safety.

How do I replace the grass trimmer line?

Refer to the grass trimmer's specific section in the manual. Generally, it involves removing the spool cap, manually feeding new line, or replacing the entire spool with a pre-wound one.

Is this mower suitable for very large gardens?

The mower is designed for medium to larger lawns. For extremely large or complex gardens, consider mower models with wider cutting paths or extended battery life options.

How do I switch between mowing, mulching, and collecting functions?

The mower typically uses a mulch insert or a grass box. Refer to your product manual for specific instructions on how to configure the mower for its different functions.

What maintenance is required for the brushless motor?

Brushless motors generally require very little maintenance. Ensure the motor vents are kept clear of debris to prevent overheating.

Troubleshooting

Mower or trimmer will not start.

Ensure both batteries are fully charged and correctly inserted. Check if safety features (e.g., handle engagement) are properly activated. Consult the manual for specific interlock mechanisms.

Reduced cutting performance.

Check for tangled grass or debris around the blade and motor housing. Ensure the cutting height is not set too low for the grass condition. Sharpen or replace the mower blade if it is dull.

Trimmer line is not feeding automatically.

Ensure the line is correctly wound onto the spool and properly threaded through the head. Clear any debris that might be obstructing the line feed mechanism. Manually advance the line if necessary, following the manual's instructions.

Batteries not charging.

Verify the charger is properly connected to a working power outlet. Ensure the batteries are clean and free of debris at the contact points. Try a different compatible battery or charger if available.

Uneven cut on the lawn.

Make sure the grass is dry. Ensure the cutting height is set uniformly across all settings and that the mower is not tilted excessively. Check for bent or damaged blades.
