GENERAL SAFETY RULES Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are certain hazards involved with the operation of the product. Using the machine with respect and caution will considerably lessen the possibility of personal injury.

DO NOT OPERATE THIS MACHINE UNTIL it is assembled and installed according to the instructions. 2. 12. OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are not familiar with the operation of this machine. SUPPORT ALL SANDING WORKPIECES with a table or additional support at table height.
POWER CONNECTIONS IMPORTANT: Make sure the electrical characteristics are the same between the motor nameplate and the power source and make sure the power circuit the machine will be used on is properly fused and that wire size is correct. IN ALL CASES, MAKE SURE THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED. WARNING: DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.
EXTENSION CORDS Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug.
