### General
* Hold workpiece tight, pressing the workpiece firmly into the table, push at a steady rate through the blade
* Only work on pieces you can safely hold by yourself. If it's too large, ask for another member's help to hold the material
* Keep your hands out of the cutline at all times
* Keep work in contact with table or stops. Do not freehand above the surface. Elevated parts will be grabbed by the blade
* Make sure the workpiece is supported e.g. pieces with overhangs or circular pieces
* Don't force the blade to cut a small radius curve. If this is required make it with multiple small cuts
* Never back out of a radius cut while the machine is running
* Do not leave the machine running unattended
* Have a wide/stable stance
* If the workpiece gets stuck in the blade, stop the machine and gently remove the piece
