Operating the Router
1. Powering On/Off
To turn the router ON, slide the power switch to the 'I' (ON) position. To turn OFF, slide the switch to the 'O' (OFF) position.
2. Routing Techniques
Always ensure the workpiece is securely clamped. Hold the router firmly with both hands. For best results, make multiple shallow passes rather than one deep cut.
