  3. 3. die grinder <ul><li>The die grinder is used for small grinding applications. </li></ul><ul><li>The grinder must be hooked up to the pneumatics system for use. </li></ul><ul><li>The bit may be changed depending on the application. </li></ul><ul><li>The grinder accepts different sized collets corresponding to the different shanks of the grinding bits. </li></ul><ul><li>While grinding, wear the full face mask and respirator. </li></ul>
  4. 4. cut-off tool <ul><li>While using the cut-off tool, wear the full face mask and respirator. </li></ul><ul><li>The cut-off tool must be hooked up to the pneumatics system for use. </li></ul><ul><li>Hold the tool so that the clear plastic shield faces you. </li></ul><ul><li>Use the tool to make straight cuts only. </li></ul><ul><li>Hold the tool with two hands while cutting. </li></ul><ul><li>Don't apply excessive pressure when cutting, as the blade may break. </li></ul>
  5. 5. impact wrench <ul><li>The impact wrench is used to securely tighten a nut. </li></ul><ul><li>The impact wrench must be hooked up to the pneumatics system for use. </li></ul><ul><li>The wrench accepts 3/8&quot; sockets. </li></ul><ul><li>Toggle the direction with the switch located on the handle. </li></ul>
  6. 6. angle grinder <ul><li>A grinding disc is damaged and unusable if: </li></ul><ul><ul><li>Cracks are visible </li></ul></ul><ul><ul><li>The disc is irregularly shaped near the outer edge. </li></ul></ul><ul><li>Grind with foremost part of disc and away from the central hub. </li></ul><ul><li>While grinding, wear the full face mask and respirator. </li></ul><ul><li>While grinding, hold the tool with two hands. </li></ul><ul><li>Set down and store the angle grinder with the disc positioned downwards. </li></ul><ul><li>Allow the disc to spin to a stop before setting down the tool. </li></ul><ul><li>The button on top locks the grinder so that the blade may be changed. </li></ul><ul><li>Do not lock the grinder while the disc is spinning </li></ul>
  7. 7. reciprocating saw <ul><li>Use the reciprocating saw for rough cuts only. </li></ul><ul><li>Use any fine toothed blade when cutting metal. </li></ul><ul><li>Use any coarse toothed blade when cutting plastic or wood. </li></ul><ul><li>Use a hex wrench to loosen and tighten the blade. </li></ul><ul><li>Adjust the saw speed using the dial on top of the saw. </li></ul><ul><li>Lock and unlock the tool’s trigger with a button on the side of the tool. </li></ul><ul><li>Position the rocking guide against the work piece to steady the tool. </li></ul><ul><li>Hold the tool with one hand forward and one hand positioned on the handle. </li></ul>
  8. 8. circular saw <ul><li>Clamp down the work piece. </li></ul><ul><li>Be cautious that the blade beneath the cutting plane does not make contact with either yourself, the ground, or any blocks used. </li></ul><ul><li>Hold the saw with two hands </li></ul><ul><li>Don't force the saw into the work piece. Instead, allow the saw to pull itself along </li></ul><ul><li>How to adjust the saw’s cutting angle and depth: </li></ul><ul><ul><li>Angle: Use the lever on the front of the saw. </li></ul></ul><ul><ul><li>Depth: Use the lever near the back of the saw to set and lock the cutting guide. </li></ul></ul><ul><li>Check that the appropriate blade is installed before cutting. </li></ul><ul><li>Sometimes it is necessary to lift the blade guard to begin the cut. </li></ul>
  9. 9. chop saw <ul><li>Clamp down the work piece. </li></ul><ul><li>The clamps can be positioned on either side of the cutting blade. </li></ul><ul><li>Check that the appropriate blade is installed. </li></ul><ul><li>Allow the blade to spin up before beginning to cut. </li></ul><ul><li>Lower the blade slowly to avoid jams. </li></ul><ul><li>In case of a jam, release trigger and raise the blade before restarting the cut. </li></ul>
  10. 10. band saw <ul><li>Don't apply pressure to the cutting arm. </li></ul><ul><li>Set the spring for an appropriate cutting pressure. </li></ul><ul><li>Set the blade opening to the smallest possible distance. </li></ul><ul><li>Use the vice set to the desired correct angle to secure the work piece. </li></ul><ul><li>Start the saw before the blade makes contact with the work piece. </li></ul><ul><li>If the blade does not start to move, turn off the saw, spin the blade by hand, and then restart the saw. </li></ul><ul><li>To convert to a vertical saw: </li></ul><ul><ul><li>Put the saw arm in the vertical position </li></ul></ul><ul><ul><li>Screw on the table </li></ul></ul><ul><li>Ask for assistance if the blade falls off. </li></ul>
  11. 11. drill press <ul><li>Drilling speed can be adjusted by changing the belts at the top of the drill press. </li></ul><ul><li>Use the chuck and chuck key to vary the space for the desired bit. </li></ul><ul><li>Be sure the chuck key is removed prior to turning on the drill press. </li></ul><ul><li>When drilling a large hole, begin by drilling a smaller pilot hole and gradually working up to the desired final size. </li></ul><ul><li>Be sure not to allow the spinning drill bit to touch and damage the table. </li></ul>
