9. User Tips

• Always Test: Before making a final cut on your project, always test your settings (depth, speed) on a scrap piece of the same material.
• Bit Selection: Use the correct type and size of router bit for your specific application. Sharp bits produce cleaner cuts and reduce strain on the tool.
• Workpiece Security: Ensure your workpiece is always securely clamped to prevent movement during operation, which can lead to inaccurate cuts or kickback.
• Dust Management: Connect a dust extraction system to the trimmer's dust port to keep your workspace clean and improve visibility.
• Smooth Movement: Guide the trimmer with smooth, consistent movements. Avoid jerky motions or forcing the tool, which can damage the bit or the workpiece.
