Troubleshooting
If you encounter issues with your SEESII Electric Pruning Shears, refer to the following common troubleshooting tips:

- Blades Not Opening/Closing: Confirm the safety activation sequence (double-tap trigger) has been performed. Check for any obstructions around the blades.
- Reduced Cutting Performance: The blades may be dull or dirty. Refer to the Maintenance section for sharpening or replacement. Ensure the correct cutting mode is selected for the branch size.
