There are several hazards you need to be aware of when using a table saw.   

There are multiple hazards you need to be aware of when using the CNC router.   

* The blade is very sharp and it spins very fast. Keep your fingers away from the blade even when its not spinning. Use a push stick to keep your fingers a safe distance from the blade.  

* The tooling is very sharp and spins at over 18,000 RPM. Keep your body parts away from the cutter and spindle.  

* Always wear proper safety equipment, i.e. ear protection and safety glasses, to prevent injury.   

* Stay behind the safety line when operating the router. The router is very large and will not stop if you get in its way.   

* Hold onto material firmly and keep it against the table and fence to help prevent the material from catching on the blade. If material catches on the blade the material can shoot back at you and this is called a kickback.   

* Materials need to be securely fastened to the table by vacuum or mechanical means.

This is a video of a kickback:

* Never attempt to cut a hole the same diameter as the cuter with a down cut force cutter.  This will compress the chips and can create a fire due to the air draw of the vacuum table.
