1. **Unplug the Tool**: Ensure the rotary tool is turned off and unplugged to prevent accidental activation. 2. **Locate the Spindle Lock**: Identify the spindle lock button, usually located near the tool's collet. This button prevents the shaft from rotating, allowing you to change bits. 3. **Press and Hold the Spindle Lock**: Depress the spindle lock button and rotate the collet nut by hand until the spindle lock engages, preventing further rotation. 4. **Loosen the Collet Nut**: Use a wrench (often provided with the tool) to turn the collet nut counterclockwise. This loosens the collet, which holds the bit in place. 5. **Remove the Old Bit**: Once the collet nut is loose, pull out the old bit from the collet. 6. **Insert the New Bit**: Choose the appropriate bit for your task and insert it into the collet. Ensure it is seated properly and at the desired depth. 7. **Tighten the Collet Nut**: While holding the spindle lock button, use the wrench to tighten the collet nut by turning it clockwise. Ensure it is snug but avoid over-tightening, which can damage the tool or bit. 8. **Release the Spindle Lock**: Once the collet nut is secure, release the spindle lock button. 9. **Test the Bit**: Plug in the tool and briefly turn it on to ensure the bit is securely fastened and spins correctly without wobbling. 10. **Safety Check**: Always wear appropriate safety gear, such as goggles and gloves, when operating the rotary tool.
