Operating Your STIGA A300
Understand the key features and functions to effectively operate your robotic lawnmower.
1. Starting and Stopping
To start a mowing session, use the STIGA.GO app or the controls on the mower itself. To stop the mower immediately, press the large STOP button located on the top of the unit. The mower will cease operation and return to its charging station or await further commands.
2. Scheduling Mowing Sessions
Utilize the STIGA.GO app to create customized mowing schedules. You can set specific days and times for the mower to operate, ensuring your lawn is always perfectly maintained according to your preferences.
3. Mowing Patterns and Zones
The STIGA A300 employs systematic mowing patterns, such as parallel lines, checkerboard, or grid, to ensure complete and efficient coverage of your lawn. These patterns can be selected and adjusted directly within the STIGA.GO app for different areas of your garden. The mower supports multiple mowing zones, allowing you to manage complex garden layouts.

5. GPS-RTK Navigation and 4G Connectivity
The A300 utilizes GPS-RTK technology for highly accurate positioning and precise garden navigation. Free, lifelong 4G connectivity ensures uninterrupted communication between the robot, satellites, and the reference station, maintaining high precision in its movements.
Maintenance and Care
Regular maintenance ensures the longevity and optimal performance of your STIGA A300.
1. Cleaning the Mower
Periodically clean the exterior of the mower with a damp cloth. Remove any grass clippings, dirt, or debris from the cutting deck, wheels, and sensors. Ensure the charging contacts are clean and free of corrosion.
2. Blade Inspection and Replacement
Inspect the 4 blades regularly for wear, damage, or dullness. Worn blades can affect cutting quality. Replace blades as needed, following the instructions in the full product manual. Always wear protective gloves when handling blades.

3. Battery Care
The STIGA A300 is powered by a durable battery. For optimal battery life, allow the mower to fully charge before its first use. Avoid prolonged storage with a completely discharged battery. The STIGA.GO app provides real-time battery status.
4. Winter Storage
Before winter, thoroughly clean the mower and charge its battery. Store the mower and charging station in a dry, frost-free environment. Refer to the full manual for detailed winter storage instructions.
Troubleshooting Common Issues
This section addresses common problems you might encounter with your STIGA A300.
1. Connectivity Problems
If the mower loses connection to the app or satellite signals, ensure your smartphone's Bluetooth is on and the mower is within range. Check for any obstructions blocking satellite signals. Restarting the app or the mower can often resolve minor connectivity issues.
2. Mowing Irregularities
If the lawn is not cut evenly or areas are missed, check the blades for sharpness and damage. Verify that the virtual boundaries are correctly defined in the app and that no new obstacles have been introduced to the mowing area. Adjusting mowing patterns or height settings via the app may also help.
3. Error Indicators
The mower may display error messages or indicators. Consult the STIGA.GO app for detailed explanations of specific error codes and recommended solutions. Common errors might relate to obstacles, low battery, or sensor issues.
