1.Crosscutting a. Use a crosscut or combination blade. Always use sharp blades. Make sure blade is always cutting down towards front or operator's side of table. b. Adjust the depth of cutt so that the teeth clear the thickness of material by the depth of the teeth. c. Be sure saw guard and splitter are in place. Check anti-kickback device to make sure it is working. d. Always use the miter gage when crosscutting. A wood facing is recommended for the miter gage. e. Never use the ripping fence as a guide when crosscutting short pieces. Use a stop on the miter gage or stop blocks clamped to the ripping fence or the table top. f. Place board against the miter gage and saw the board saving the cutting line. g. Do not force work through the saw.
 * B. SAFE OPERATION PROCEDURES:**

2. Ripping: a. Use a ripping or combination blade. b. Use ripping fence as a guide. Never saw freehand. c. Double check cutting width by measuring from fence to outer teeth. Also check front and back of blade so fence will not bind material to blade. d. When ripping narrow pieces use a push stick. e. Be sure guards are in place for all sawing operations. f. Use a helper or a roller stand to support long pieces of material while sawing. g. Adjust blade to proper height, 1/4" to 1/2" above the material being sawed. h. Do not force mateial into blade. IIf blade overheats stop saw immediately and check for dullness or binding of blade.

3. Dadoing or Plowing: a. Use a dado blade if available. A combination blade may be used and the fence varied with each pass. b. raise the saw to the desired depth of cut. Make pass on waste piece before cutting into actual work piece. c. This operation may require the guard to be removed if the materail is to be dadoed on edge.

4. Bevel Cuts (Ripping): a. Use a combination or ripping blade. b. Adjust saw by tilting the arbor to the angle desired. c. Adjust blade to proper height 1/4" to 1/2" above work. d. Adjust ripping fence to desired width of cut.

5. Bevel Cut (Crosscutting): a. Use a combination or crosscutting blade. b. Use miter gage (not the ripping fence) and follow the steps as listed in tem 34.


 * C. GENERAL SAFETY PRACTICES:**

1. Wear eye protection and proper clothing. 2. obtain permission from instructor to opertae bench saw. 3. Use only sharp blades of the proper type for the job. 4. Be sure blade is correctly installed in saw. make certain power is off and properly disconnected before removing blade insert. To losen arbor nut,turn wrench toward normal direction of travel holding blade with waste piece of wood. Do not overtighten arbor nut when replacing blade. 5. Do not stand in line with the blade while sawing or aloowing fingers to hands to be in line of cut. 6. Be sure that all adjustemnts are tight and the table part of the saw is free to tools, chips, small pieces of wood or other materials. 7. Do not talk to anyone while using the saw. The operator should be the only person inside the safety zone. 8. Be sure the floor is clean and free from scraps and rubbish. Do not work on wet or slippery floors. Non-skid materials are recommended. 9. Saw only material that has a straight edge. 10. Study the adhjustments and make sure you understand them before starting to work. 11. Use saw guard where possible. 12. Use a "push" syick for ripping narrow pieces. 13. Hold material against the ripping fence when ripping, and miter gage when crosscutting. Never saw freehand. 14. Never use the ripping fence for a gage when crosscutting short pieces. 15. Do not place the hands over or in front of the blade. Never reach over the blade. 16. Turn off the saw before removing short pieces from near the blade. 17. Be sure the power is "locked" off before adjusting or working on the saw.
