Safety First
Safety is your responsibility. Use the proper protective
equipment and "safety sense" when building and
operating your CNC Router.
Routers have a high voltage power supply. Router bits spin at 30,000 rpm
and have cutting edges that are hazardous. The operator should understand
these hazards and take appropriate safety precautions before operating the
Router.
Please review the entire assembly instructions before
starting to build the E3 CNC Router.
