1 Agricultural Mechanics and Technology Power Tool Safety Rules Name: BAND SAW Use: Cutting curves, circles and irregular shapes. 1. Use clean SHARP blades. 2. The teeth should always point DOWN. 3. Adjust the upper blade guard and thrust bearings so only the necessary length of blade exposed or JUST ABOVE THE WOOD. This will prevent blade breakage and assure a SMOOTH cut and ensure SAFETY. 4. The wheel will turn in a CLOCKWISE direction. 5. Hold the stock FIRMLY on the table. 6. Keep your fingers at least 2 inches from the blade. 7. Feed work into the band saw firmly and at a rate that will not OVERLOAD the saw. 8. If you need to back the band saw out of a long cut, first TURN OFF MACHINE and allow the machine to come to a full stop. 9. If you are cutting sharp curves make several RELIEF CUTS. 10. The correct cutting position for operators is facing the blade, standing slightly to the LEFT. COMPOUND MITER SAW Use: To make miter, bevel and crosscut cuts. It one of the best tools to cut joints on all kinds of moldings. Windows and door trim, etc. 11. Make sure the saw is securely BOLTED to a bench or stand. 12. Always UNPLUG the machine before servicing or changing blades. 13. Keep all GUARDS in place. 14. Keep your hand at least 4 inches from the blade. 15. Use the clamp on the saw when you CUT SHORT PIECES. 16. Make sure the wood is not in CONTACT with the blade before starting the saw. 17. Always hold the wood tightly against the FENCE. 18. When make a sliding cut PUSH THE SAW AWAY FROM YOU.

2 19. The red line indicates where you can safely hold your HAND. 20. Always FOCUS on the task at hand and be aware of your surroundings. 21. Support long work piece at the same height as the SAW TABLE. CIRCULAR SAW Use: A general purpose saw. The circular saw is probably the most commonly used power saw and the most commonly abused. 22. Always CLAMP your wood 23. Allow one piece of the work piece to fall freely to avoid KICK-BACK. 24. Use BOTH hand(s) when cutting. 25. Keep the CORD away from the blade, 26. Set the depth of CUT 1/8 to ¼ greater than the thickness of stock. 27. Never remove saw from a cut while the blade is ROTATING. 28. When starting the saw, center the saw blade in the kerf and check that the saw BLADE is not touching the stock. 29. Release the TRIGGER immediately if the blade binds or stalls. 30. The size of the saw is determined by: DIAMETER OF BLADE 31. CARBIDE tipped blades have hard steel inserted on the teeth to keep the blade sharp. DRILLS Use: Drills are used to create holes, drive in screws and other work and are undoubtedly the most widely used power tool in the world. 32. Tighten the bit securely in the CHUCK. 33. Use the variable speed button by pulling the TRIGGER. 34. Firmly grab the HANDLE to maintain control. 35. Don t FORCE the tool. 36. As you get close to breaking through the work piece, reduce the PRESSURE and allow the bit to pass through the hole easily. 37. Drills are rated by the capacity of their CHUCK. (1/2 or 3/8 ) 38. In a binding situation, the tool will react in the OPPOSITE direction of the turning bit. When drilling into the wood (clockwise), the tool will try to spin counter clock wise.

3 DRILL PRESS Use: To accurately drill holes 39. Tighten the bid securely in the CHUCK. 40. The smaller the bit the FASTER the speed 41. Don t FORCE drilling. 42. As you get close to breaking through the bottom of the work piece REDUCE PRESSURE and allow the bit to pass through easily. 43. Adjust the variable speed setting with the machine ON. 44. Always CLAMP your work. 45. When using a spade bit turn your work over when the point comes through to avoid SPLINTERING. 46. When drilling wood with the spade use the SLOW setting. 47. The drill press operates on 120 volts. GRINDER (ANGLE GRINDERS) AND (BENCH) Use: Accepts a variety of attachments and accessories that allow the tool to be used for grinding, sanding, polishing, wire brushing or cutting-off operations. 48. Wheels must be used only for their RECOMMENDED jobs. For example do not grind with the side of a cut-off wheel. It will shatter. 49. Make sure your ACCESSORY blade is the recommended size for the machine. 50. Before using, INSPECT wheel for chips and cracks. 51. Make sure your work is CLAMPED when using an angle grinder. 52. Position the CORD away from the spinning accessory. 53. Bench grinders rests need to be adjusted 1/8 INCH from the wheel. 54. When using an angle grinder maintain a FIRM on the tool and always use an auxiliary side handle. 55. Always be AWARE of your surroundings to protect yourself and others in the shop. JIG SAW Use: To cut curves or irregular shapes on plywood or other large boards. 56. Use SHARP blades. 57. Never use twisted, broken or warped SAW BLADES. 58. Make sure the ADJUSTING SCREW is tight before making the cuts.

4 59. Always cut AWAY from your body. 60. Start the blade BEFORE it comes in contact with the wood. 61. The blade has a RECIPROCATING action. 62. At the END of the cut reduce pressure on the saw to prevent the wood from splintering. 63. When inserting a new blade in it should be put COMPLETELY in the chuck and then tightened. JOINTER Use: Is a machine used to true up stock. That is, you can straighten, smooth square up and size boards. 64. Never allow your hand to pass directly over the CUTTER HEAD. 65. Do not use a jointer to process stock less than 2 INCHES wide or 12 INCHES long. 66. Stand to the LEFT of the jointer, never directly behind it. 67. Feed the stock into the machine in the direction OPPOSITE the direction of the grain. 68. Do not allow your fingers to come any closer to the rotating knives that 4 inches when jointing stock. PLANER Use: Is designed to surface boards to thickness and to smooth rough cut lumber. 69. Check the boards to be sure it is free of NAILS, loose knots and other imperfections. 70. The board should be a minimum length of 12 inches. 71. Always stand to one side when planning. Never stand BEHIND the board. 72. Keep your hands away from the board after it starts through the planer 73. Never look into the planer as the board is passing through. 74. If the board sticks, TURN OFF THE MACHINE. 75. Never STAND BEHIND a board being planed.

5 RECIPROCATING SAW Use: the reciprocating saw can be used to cut metal, pipe, woods, nail embedded wood and other materials. 76. Keep your hands away from the BLADE and SHOE. 77. When you start your saw allow the blade to reach FULL speed before contacting the work piece. 78. Always hold the shoe of the saw firmly against the work to prevent BLADE BREAKAGE and OPERATOR INJURY. ROUTERS Use: One of the most versatile tool as it is used to cut dadoes, rabbets and grooves 79. Use the proper WRENCHES to tighten the nuts that hold the bit or cutter. 80. Adjust the bit or cutter depth and lock all LEVERS. 81. Hold the router firmly in BOTH hand(s). 82. Always move the router in the proper cutting DIRECTION. (same direction as the chips are being thrown) 83. Set the router on its SIDE when done cutting. 84. Always turn the router AWAY from you when stopping. 85. Never start the tool when the bit is touching the WORK PIECE. POWER SANDER (STATIONARY) Use: They can be used to follow up any type of cutting and finishing operation. End grain, face grain, edges, curves and irregular shapes can be sanded. 86. When using the disc hold the stock firmly on the TABLE. 87. Keep the stock in motion when sanding to prevent burning due to FRICTION. 88. Disc sanding should not be done FREEHAND. 89. Always sand in the direction of the GRAIN. 90. Do not operate with torn sandpaper 91. Do not wear loose clothing or gloves. 92. Make sure the belts are mounted correctly on the machine.

6 OSCILLATING SPINDLE SANDER Uses: Sanding curved and irregular shaped wood. 93. Make sure you know the direction that the spindles turn when replacing paper. 94. Feed workpiece into sanding sleeve AGAINST the direction it is rotating. 95. Secure your work by making sure the workpiece is securely on the table. Hold with BOTH hand(s). SANDERS (FINISHING/ORBITAL) Use: To make the final sanding passed before finishing the project with stain or paint. 96. Always sand with the GRAIN. 97. Use a PUNCH PLATE to avoid dust buildup which causes FRICTION. 98. Hold the sanders FIRMLY with both hands. 99. Do not force to much PRESSURE on the sander as it may cause damage to the sander If the sander is equipped with a DUST BAG, empty it frequently. SCROLL SAW Use: Is designed to cut sharp curves and angles on the both the outside edges and interior sections of work with up and down or reciprocating motion The blade needs to be installed in a VERTICAL position with the teeth pointing DOWN Do not allow your fingers to come any closer than 2 from the blade Keep your fingers to the SIDE of the blade Adjust the tension to 0 when installing the blade The blade speed MAY BE adjusted when you operating the saw. TABLE SAW Use: The saw is used for ripping boards to width and crosscutting then to length The blade should be adjusted so that is ONE TOOTH OR 1/8 INCH above the wood being cut

7 107. Always use the GUARD When ripping use FENCE and a PUSH STICK Never crosscut freehand use a MITER GAUGE STAND to one side of the blade Do not allow your fingers to come closer than 6 inches Do not USE the fence as a cut-off stop when CROSS CUTTING When you start your saw, allow the blade to reach full speed before CONTACTING the work piece The table Saw operates on 240 volts The arbor or shaft that holds the blade has LEFT HAND nut with COARSE threads. PNEUMATIC NAILER Use: A nail gun or nailer used to fasten material with compressed air Ensure air hoses and connections are in good operating condition Use correct nails or staples for the job Do not lift or carry nailer by the air hose Point the tip of the nailer away from the body and from others. BELT SANDER Use: A smoothing tool that uses a rotating abrasive wheel to produce a smooth finish Use both hand with moderate pressure Always set back rollers down first to prevent gouging the wood Make side to side belt adjustments with the machine on Be aware of the cord to avoid damage.
