                    Drill Press Safety Rules:
• Secure bit in chuck by placing the chuck key in two of the three holes and
  twisting firmly.
• Remove chuck key immediately after installing or removing a bit.
• Brush the table with a shop brush, never with your hand.
• Use a scrap block of wood to drill into under the work place.
• To prevent injury to the hands when working on the drill press, always secure
  your work piece to the table by either clamping, vice, or jig.
• Make all set-up adjustments such as table height, depth stop, and fastening
  material to table before machine is turned on.
• Consult the speed chart for correct speed setting when drilling various
  materials.
• The bit should be withdrawn frequently when drilling large or deep holes to
  prevent damage to the bit. Locate center of holes with a center punch.
• A V-Block should be used when drilling round material.

              Table Saw Safety Rules:
• Always use the blade guard.
• The saw blade should be adjusted to cut above the wood no more than 1/8”.
• All adjustments are to be made when the saw is at a complete stop.
• Freehand cuts should not be attempted on the table saw.
• To prevent injury in case of kickback, always stand to the side of the blade.
• Never reach across the blade to retrieve a piece of wood you have cut.
• When tilting the blade, check to be sure it doesn’t hit the guard, rip fence or
  miter gauge before you turn the saw on.
• Never start cutting until the saw has attained full speed.
• When starting saw, if it doesn’t should right, turn it off immediately.
• Never remove scrap wood from the saw while it is turning.

   Table Saw Safety Rules Continued:
Ripping:
• Edge of wood touching rip fence must be straight and smooth.
• Check fence to be sure it is locked in place before turning the saw on.
• Use a push block for wood narrower than 4”.
• Assistance must be available when ripping long pieces of wood.
• Wood should never be left between the fence and the blade.
Crosscutting:
• Fingers should never be closer to the blade than 4”.
• Check miter gauge to be sure it slides freely and clears the blade.
• Set proper angle to be cut and lock in place before turning the saw on.
• Rip fence must be clear of work area.
• Never use rip fence and miter gauge at the same time.
• All work must be held firmly against the miter gauge.

       Disc Sander Safety Rules:
• Make sure the sanding surface is not loose.
• Make sure the metal table is adjusted to the necessary
  angle.
• Always use the downward motion of the rotating disc. The
  downward motion of the rotating disc will allow the user to
  have control and prevent injury.
• Keep fingers far from the sanding surface to prevent
  injury.
• Make sure the disc sander has come to a complete stop
  before making adjustments or finished.

         Band Saw Safety Rules:
• Adjust guide wheels approximately 1/4” above stock.
• Position hands on the stock that is being cut so that you are
  not in front of the blade.
• Fingers should never be closer to the blade than 2”.
• Use relief cuts to prevent breaking blade on tight curve
  cuts.
• Stock must be firmly held and supported against the
  downward thrust of the saw.
• Before backing out of a cut, turn the power off. This
  practice should be avoided as much as possible.
• Shut off power immediately if the blade should break.
• Feed stock straight rather than at an angle to the blade.
