WAC 296-806-48074. Make sure shapers meet these requirements

(1) You must guard the cutting head of the shaper by enclosing it with either: (a) A fixed guard, such as a cage; or (b) An adjustable guard designed to keep the operator's hand away from the cutting edge. (2) You must make sure the diameter of a circular shaper guard is at least as large as the greatest diameter of the cutter. Note: A warning device of leather or other material attached to the spindle is not an acceptable substitute for a guard. (3) You must guard all sections of the cutting tool except for an opening to allow access to the work piece by the cutting tool. Note: A ring guard is one means of satisfying the guarding requirement for cutting tools when involved in free hand or template shaping. (4) You must make sure all double-spindle shapers have a spindle starting and stopping device for each spindle.
