19.Make your workshop child proof with padlocks, master switches or by removing starter keys.

20.Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that can result in serious injury.

21.Remove loose items and unnecessary work pieces from the area before starting the machine.

22.Maintain a balanced stance at all times so that you do not fall or lean against the conveyor belt or other moving parts. Do not overreach or use excessive force to perform any machine operation.

23.Keep hands clear while feeding workpieces onto the conveyor table. The workpiece will be forced down as it begins to feed into the machine, causing a pinching action between workpiece and conveyor table.

24.Stand to one side of the conveyor table and do not let anyone else stand in line with the table while a workpiece is being fed through the machine.

25.Do not attempt to sand stock shorter than 12 inches long without butting a board of equal thickness behind it to help it through the machine. Do not sand stock less than 1/8” thick.

26.Never reach into a running machine. Turn off and disconnect from power source before attempting to retrieve parts from within the machine.

27.Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for which it was not designed. The right tool will do the job better and safer.

28.Use recommended accessories; improper accessories may be hazardous.

29.Turn off the machine and disconnect from power before cleaning. Use a brush or compressed air to remove chips or debris — do not use your hands.

30.Do not stand on the machine. Serious injury could occur if the machine tips over.

31.Never leave the machine running unattended. Turn the power off and do not leave the machine until all parts come to a complete stop.
