Dress properly for your work. Remove coats and jackets, and roll up loose or dangling sleeves. Remove all jewelry. Pin-up long or dangling hair. It is advisable to wear a shop apron that is snugly tied. Open-toed shoes are not allowed and steel-toes safety shoes are recommended. EYE PROTECTION. Wear safety glasses or a face shield when doing any operation that may endanger your eyes. Be sure you have enough good light to see what you are doing without straining your eyes. CLEAN HANDS. Keep your hands clean and free of oil or grease. You will do better and safer work, and the tools and your project will stay in good condition. CONSIDERATION OF OTHERS. Be thoughtful and helpful toward others. Be sure that the work you are doing does not endanger someone else. Caution others if they are violating a safety rule. TOOL SELECTION. Select the proper size and type of tool for your work. An expert never uses a tool unless it is sharp and in good condition. CARRYING TOOLS. Keep sharp-edged and pointed tools turned down. Do not swing or raise your arms over your head while carrying tools. CLAMPING STOCK. Whenever possible, mount the work in a vise, clamp, or special holder. This is especially important when using chisels, gouges, or portable electric tools. USING TOOLS. Hold a tool in the correct position while using it. Most edged tools should be held in both hands with the cutting motion away from yourself and others. Be careful when using your hand or fingers as a guide to start a cut. Test the sharpness of a tool with a strip of paper or a scrap or wood. DO NOT USE YOUR FINGERS. WORKING SPEED. Do not “rush and tear” through your work. The good craftsworker knows that a steady, unhurried pace is safest and produces the best work. BENCH ORGANIZATION. Keep your project materials carefully organized on your bench with tools located near the center. Do not pile tools on top of each other. Never allow edged or pointed tools to extend out over the edge of the bench. 4 of 33 FLOOR SAFETY. The floor should be clear of scrap blocks and excessive litter. Keep projects, sawhorses, and other equipment and materials you are using out of traffic lanes. Immediately wipe up any liquids spilled on the floor. MATERIAL AND PROJECT STORAGE. Store and stack your project work carefully in assigned areas. LIFTING. Protect your back muscles when lifting heavy objects. Have someone help you. Lift with your arm and leg muscles. Secure help with long boards, even if they are not heavy. FIRE PROTECTION. Many finishing materials, thinners, etc. are highly flammable. Others are toxic. Because of this, it is important that these materials be used only in approved areas. In addition, close cans of finishing materials and thinners immediately after use. Use flammable liquids in very small quantities. Be sure the container is labeled. Dispose of oily rags and other combustible materials immediately, or store them in an approved container. Secure approval before you bring any flammable liquids into the shop. CLEAN UP. Before leaving the wood shop, operators are REQUIRED to put away all the tools they have used and to clean up any mess they have made. Consideration for other members would encourage cleaning up the entire area. Vacuums, brooms, and dust pans have been provided for this purpose. OPERATORS WHO DO NOT CLEAN-UP AFTER THEMSELVES WILL LOSE SHOP PRIVILEGES !!! Safety First!!! The most important thing to remember when working with machines and tools of any kind is Safety first! Accidents happen quickly, especially around machines and power tools, and they can result in serious injury and even death. That is why it is absolutely essential that anyone using machines and power tools respect all that they can do: both the good and the bad. So remember, whenever you are in the Wood Shop, your primary focus should always be: Safety first! 5 of 33 Wood Shop Safety Rules REMEMBER, ALL WOOD WORKING TOOLS, PARTICULARLY POWER TOOLS ARE DESIGNED TO REMOVE MATERIAL! MATERIAL CAN INCLUDE YOUR OWN FLESH, BONES, AND BLOOD! SAFETY FIRST!!! 1. Before operating any power tool or machine you must become thoroughly familiar with the way it works and the correct procedures to follow in its use. As you learn to use a machine the correct way, you will also be learning to use it the safe way. You must be instructed in the correct and safe use of any machine before you can use that machine. 2. Wear appropriate clothing. Remove coats or jackets, and roll up loose sleeves. 3. You must be wide awake and alert. Never operate a machine when you are tired or ill. 4. Think through the operation before performing it. Know what you are going to do, and what the machine will do. 5. Make all the necessary adjustments before turning on the machine. Some adjustments on certain machines will require instructor’s assistance. 6. Never remove or adjust a safety guard without the instructor’s permission. 7. Use approved push sticks, push blocks, feather boards, and other safety devices. Some operations may require the use of a special jig or fixture. 8. Keep the machine tables and working surfaces clear of tools, stock, and project materials. Also keep the floor free of scraps and excessive litter. 9. Allow the machine to reach its full operating speed before starting to feed the work. 10.Feed the work carefully and only as fast as the machine will easily cut. 11.Maintain the MARGIN OF SAFETY specified for the machine. This is the minimum distance your hands should ever come to the cutting tool while in operation. 12.If a machine is dull, out of adjustment, or not working properly, shut off the power immediately and inform the instructor. 13.When you are operating the machine, you are the only one to control it. Start 6 of 33 and stop the machine yourself. If someone is helping you, be sure they understand that they are expected to know what to do and how to do it. 14.Do not allow your attention to be distracted while operating a machine. Also, be certain that you do not distract the attention of other machine operators. 15.Stay clear of machines being operated by other students. See that other students are “out of the way” when you are operating a machine. 16.When you have completed an operation on a machine, shut off the power. Wait until it stops before leaving the machine or setting up another cut. Never leave a machine running while unattended. 17.Machines should not be used for trivial operations, especially on small pieces of stock. Do not play with machines. 18.Do not “crowd around” or wait in line to use a machine. Ask the present operator to inform you at your work station when finished. Common standards of courtesy may slow you down, but they will make the shop a safer and more pleasant place to work. 7 of 33 General Information about Wood Wood: A Bundle of Straws When working with wood, it is helpful to think of it as a bundle of straws, with the straws representing the wood fibers. Cutting across the fibers (perpendicular to the straws) is easier and safer than cutting in line with the fibers (parallel to the straws). Dimensional Lumber vs. Plywood A piece of dimensional lumber, e.g. a “2x4”, is a single piece of wood. All of its wood fibers run in the same direction. Plywood is composed of a multiple thin pieces of wood glued together. The fibers of one thin piece are perpendicularly oriented to the fibers of the next thin piece. Types of Cuts There are many different ways to cut wood. The two main types of cuts you are most likely to make are cross cuts and rip cuts. You may also make curved, miter and bevel cuts. As you will see, different power tools excel at different cuts. 1. Cross cut –cutting perpendicular to the wood fibers and / or cutting a piece of plywood to 2. 3. 4. 5. length Rip cut –cutting parallel to the wood fibers and / or cutting a piece of plywood to width Curved cut Miter cut –an angled cut across the face of a piece of wood Bevel cut –an angled cut across the depth of a piece of wood 8 of 33 Table Saw Most Likely Uses 1. Rip cutting and cross cutting wood and plywood. 2. Making dados. Table Saw Safety 1. Watch out for kickback! Leading causes of table saw kickback include: • Wedging between the rear of the blade and the fence • Binding against the side of the blade 2. Never force a piece through the table saw • All pieces should pass through easily • If you have to force it, the piece is probably wedging or binding 3. Never cut freehand on the table saw • Always use the rip fence for rip cutting • Always use the miter gauge for cross cutting • Never use the miter gauge and rip fence at the same time (exceptions require special training) 4. Do not use the rip fence for what are really cross cuts 5. All edges placed against the rip fence must be straight 6. Never cut warped or twisted stock on a table saw. The wood being cut must lie flat on the table 7. Use a push stick for narrow rip cuts of 6” or less in width 8. The table saw blade should project no more than a 1/2” above the piece of wood you are cutting 9. If using out feed rollers, set them just below the height of the table. (Watch out: The rollers are heavy.) 10. Do not cut sheets of plywood that are too large for you to control by yourself. 11. Cross cutting workpieces shorter than 10” requires special equipment set up. 12. When you complete your work clean all waste and sawdust from saw, be sure the standard blade is mounted on the saw, and lower the blade below the table surface. 9 of 33 Sliding Compound Miter Saw Most Likely Uses 1. Making cross, miter, and bevel cuts in dimensional lumber and plywood 2. Cutting PVC pipe. Sliding Compound Miter Saw Safety 1. Keep protective guards in place at all times. 2. Remove scraps and other foreign items from the machine before operating the saw. 3. Make sure the piece to be cut is firmly against the table and fence before cutting. 4. Allow the blade to reach full speed before cutting. 5. Do not force the tool into the work. 6. Never hold the piece to be cut in a manner that causes your arms to cross. The majority of all cuts are made on the miter saw with the material held with the left hand on the left side of the saw while the right hand operates the machine. 7. Do not leave the area of the machine until the blade has come to a full and complete stop. 8. Always maintain a 6" margin of safety between all body parts and the blade. 9. Remove chips, scraps and cutoffs only after the blade is at a complete stop. 10. After placing the stock securely on the saw table and aligning the cut, pull the trigger. After the blade comes to full speed, lower the blade into the work at a moderate speed. When the cut is complete release the trigger and allow the blade to come to a complete stop before returning it to the upright position. 11. Use a stick or other hold down device when needed to secure short material without putting your hand in danger. 12. The workpiece should be held in place, rather than the off-fall, by the operator for all cuts. 13. NEVER use the chop saw to cut rough material length. 10 of 33 Band Saw Most Likely Uses 1. Making curved or irregular cuts in wood. 2. Cutting plexiglas. Band Saw Safety 1. Adjust the upper guide and guard to about 1/8" to 1/4” above the stock with the machine at a full stop. 2. Allow the saw to reach full speed before starting to feed your work. 3. Plan cuts carefully; lay out and make relief cuts before cutting long curves and curves of small radii. Turning holes should be made where required. Plan work so that all cuts will be made in the forward direction. Turn off power and wait for the blade to stop spinning before backing out. 4. If the stock binds or pinches the blade, do not attempt to back the stock out. Shut the power off and remove the stock after the machine stops. Backing up while the machine is running could pull the blade off the wheels. 5. When removing scrap material from the band saw table, always be aware of the blade. Use a piece of scrap stock to remove scrap pieces; do not use your hands. 6. Keep the floor areas surrounding the saw clear of scraps. Note: Given the saw’s 1/2” blade, the minimum cutting radius is 2 1/2”. 1/4” blades are available. 11 of 33 Radial Arm Saw CreatorSpace does not have this tool available at this time. 12 of 33 Table Router and Hand-Held Router Most Likely Uses 1. Shaping, edging, dadoing of wood. Hand-Held Router Safety 1. Use only bits that are specially designed for operation in high speed routers. 2. Always unplug the router before changing bits or making adjustments other than the depth of cut. 3. Do not bottom out the shank of the router bit in the collet. When possible, insert the bit to its maximum depth, and then withdraw it about 1/8" before tightening the collet. 4. Make sure the bit is firmly secured in the collet before starting work. A loose bit will work its way out of the collet, damaging your work and/or injuring you. 5. Make sure the router motor is tight in the router base before power is turned on. 6. When starting the router, make sure the bit is not in contact with anything. 7. Hold the router firmly when turning on the power to withstand the starting torque of the router motor. 8. Keep hands and loose clothing away from revolving bits and cutters. Operate the router in the proper direction. If only one side of the bit is being used, move the work against cutter rotation. If the bit is cutting on both sides, feed the work so that the bit pushes the work towards the fence (when applicable). 9. 10. Use slower speeds for larger bits. 11. Do not overload or bog down the speed of the motor. 12. Make several light cuts where large amounts of material are to be removed. 13. Always make sure the bit is sharp; if unsure, check with the instructor. 14. Always secure or clamp the work so that it cannot move during routing. 13 of 33 15. When using multi-piece router bits, ensure all nuts and bearings are tightened properly. 16. Large panel-cutting bits should not be used in a hand-held router. 17. Due to the physics of routing, dados and rabbets in solid wood are best achieved using a table saw. Dados and rabbets in manufactured material such as plywood, particle board, and MDF are better achieved using a router. Additional Table Router Safety 1. Move the workpiece in the proper direction. If only one side of the bit is being used, move the work against cutter rotation. If the bit is cutting on both sides, feed the work so that the bit pushes the work towards the fence (when applicable). 2. Use slower router speeds for longer bits. This is especially important at the router table, since large bits are more likely to be used here. 3. On the Bench Dog router lifts: Do not change router bits without first removing the throat plate. When tightening the throat plate attach screws, use only light finger pressure. Do not over-tighten one throat plate screw before tightening the other; the tightness of the first screw will prevent the throat place from being flush with the table when you tighten the second screw. 4. Use the throat plate that leaves the smallest opening around the router bit. 5. When routing small or narrow pieces, use a backer board and/or a pushstick to ensure proper support, along with a fence with a small or no opening. 14 of 33 Drill Press Most Likely Uses 1. Drilling Holes. Drill Press Safety 1. The procedure of changing spindle speed varies from drill press to drill press. Check with your instructor prior to making speed adjustments. 2. Be certain that the table and head of the drill press are secure. 3. Select the proper drill bit for the job and avoid dull bits. 4. Insert the drill bit in the chuck properly and tighten it securely before starting the drill press. 5. Remove the chuck key before turning on the power and before leaving the area of the drill press. If the chuck key is not removed it will be thrown out from the chuck at a tremendous speed when the power is turned on. 6. Use clamps or a drill vise whenever necessary to secure small or odd shaped work firmly. 7. 8. Larger bits should be run at slower speeds and smaller bits at higher speeds. This keeps the cutting edge of the bit at a reasonable speed. Use a backer board under the work or be sure the bit is over the center hole in the table when boring completely through your work. 9. Keep hands away from the rotating spindle. 10. Operate the feed lever so that drill cuts at a consistent feed rate into work. 11. Ease up on feed pressure when the bit begins to break through the work. 12. Back the bit out often to clear chips from the hole. 13. When boring to a given depth, use the depth adjustment nut or feature. 14. Stop the drill press before removing your work. 15. If work comes loose and is seized by the drill press, shut off the power immediately if you can do so without endangering yourself. If it is impossible to shut off the power, move away from the machine and move others away. Notify the instructor immediately. 15 of 33 Planer Most Likely Uses 1. Smooth lumber to an even thickness. Planer Safety 1. Do not remove more than 1/32" of wood at one time. 2. Adjust the initial depth of cut to the thickest part of the board. 3. The stock must be longer than the distance between the in feed and out feed rollers. The minimum length of stock for planing is clearly marked on each planer. 4. Do not plane stock to less than 1/4" thick. To plane thinner stock, run it through the planer with a backer board. For this special setup, obtain additional instruction. 5. Never put your hands into the planer. 6. If a board needs to be realigned on the table after being gripped by the cutterhead, use care to keep your fingers clear of the table and feed rollers. 7. Never change depth of cut after stock has been started through the planer. 8. Do not plane stock with large cracks or loose knots. 9. Always plane wood with the grain, never across or perpendicular to the grain; the planer will shred the wood. 10. Always ensure that the machine has reached full speed before inserting the wood in the machine. 11. Plane pieces of varying thickness in progressive order, starting with the thickest first. 12. Because of the possibility of flying particles, do not look into the planer while the machine is running. Stand in an upright position and to one side while you are operating this machine. 13. The maximum length of stock which can be surfaced or planed is limited only by the location of walls and other equipment surrounding the planer. 14. A planer will produce two flat, parallel faces only when the surface which was put on the table was flat and smooth to begin with. Planing a warped board 16 of 33 will only produce a warped board of even thickness. 15. Kickbacks are infrequent but possible on a planer. 16. Never adjust the speed of the planer's feed rollers. 17. If the stock gets stuck in the planer, do the following, in this order: • • • • Gently push the stock into the planer; do not overly force the material. If that doesn't work, shift the stock at a slight angle while keeping your fingers clear of the table. If that doesn't work, lower the table 1/8 turn of the adjustment wheel and repeat steps a and b until the stock starts feeding again. If the stock still will not proceed through the planer repeat steps a, b, and c until the stock starts feeding again. Do not turn the wheel more than 1/8 turn at a time; the feed rollers could lose contact with the stock and a kickback could occur. Note: Do not turn the power off while stock is in the planer; you could damage the cutterhead. Important Information About Planers The planer is used to smooth lumber to an even thickness. After flattening one side of a board on the jointer, the board is run through the planer with the flat side down on the table, which supports the board and acts as a reference surface. The cutterhead, located above the workpiece, then smoothes the opposite face and makes it parallel to the jointed face. The width of the cutterhead, which defines the size of a planer, indicates the widest board that can be surfaced. 17 of 33 Disc and Disc/Belt (Combination) Sander CreatorSpace does not have this tool available at this time. 18 of 33 Portable Belt and Disc Sanders Most Likely Uses 1. Sanding Pieces of Wood. 2. Making minor changes to the shape of a piece of wood. Portable Belt and Disc Sander Safety 1. Avoid excessive downward pressure on the belt sander. The weight of the machine should be the only pressure necessary. 2. Check to see that the belt or disc is in good condition and that the proper grit paper is installed. 60- or 280-grit papers are good choices for general use. 3. Be sure the belt is tracking properly prior to use. The belt tracking can be adjusted only while the machine is running. 4. Allow the sander to reach full speed before placing it on the piece to be sanded. 5. Lift the sander off the work before stopping the motor and wait until it is completely stopped before placing the sander on the bench. 6. Do not use the sander to sand stock smaller than the platen. 7. Use the sander in a consistent pattern and always keep it moving. 8. Belts should always be installed with the arrow pointing in the direction of motor rotation. 9. The sanders should be used at full speed at all times. 10. Always hold the piece to be sanded securely with a clamp or vise. 11. Before plugging in the machine, make sure the trigger lock is not engaged. Lay the machine on its side when inserting the plug. 12. Always use two hands when operating or carrying the machine. 13. Do not use on Plexiglas, fiberglass, or printed circuit boards (PCBs). 19 of 33 Horizontal Slot Mortiser CreatorSpace does not have this tool available at this time. 20 of 33 Hollow Chisel Mortiser Most Likely Uses 1. Making square holes in wood for mortises. Hollow Chisel Mortiser Safety Rules 1. You must be checked out on this machine before using it.Ensure the chisel and drill bit are sharp prior to installation. 2. The bit should be positioned about .O2O" below the chisel. This is approximately the thickness of a non-flexible 6" scale, or a dime. The spacing can be accomplished by installing the chisel with a .O2O" spacer between the chisel shoulder and the upper bushing. Then, install the drill bit with the bit tight against the mouth of the chisel; tighten the chuck. Remove the .O2O" spacer, slide the chisel up tight against the bushing, and tighten with the appropriate wrench. Ensure the chisel is square to the fence when it is tightened. When the machine is turned on, some squeaking is normal. It is caused by the bit rubbing against the chisel. If the noise is excessive, check your setup. 3. 4. If using the depth stop or other stops, make sure lock bolts are securely tightened. 5. Ensure the work is securely clamped in place. 6. Always use a backer board to prevent damage to the bit and minimize tear out on through mortises. 7. Do not cut more than about 1/2" deep at a time. Deeper cuts may result in the chisel getting stuck in the workpiece. If a deeper cut is desired, make a 1/2" cut, move the work piece over and make an overlapping cut of greater depth. Continue this back-and-forth process until the desired depth is achieved. 8. Harder woods will require shallower cuts and greater care in drilling. 9. Do not apply excessive force. If excessive force is required, check your setup . Important Information: The hollow chisel mortiser is uniquely capable of making a square hole. It does so by forcing a hollow, four-sided chisel into the wood, and removing the encircled waste with a special drill bit. Due to the forces involved, a lot of heat is generated. Setup of this machine is critical; improper positioning of the chisel and bit can ruin the tool or the workpiece. 21 of 33 21 15” Wide Belt Sander CreatorSpace does not have this tool available at this time. 22 22 of 33 Edge Sander CreatorSpace does not have this tool available at this time. 23 of 33 23 Pneumatic Nail Guns and Staplers Most Likely Uses 1. Drive nails and staples quickly and efficiently. 2. Increase accuracy and reduce damage to finished work due to pounding with a hammer. Pneumatic Nail Gun and Stapler Safety 1. Safety glasses must be worn when operating a nail gun or stapler. 24 2. Always point the nail gun or stapler away from any person or body parts. 3. Except when ready to actuate the nail gun or stapler, keep your finger off the trigger. 4. Always disconnect the air supply when loading or unloading the magazine, or when making adjustments. 5. Ensure the nose guard is working properly. Nose guard must be pressed against the work piece, depressing the nose guard. 6. When operating the nail gun or stapler, make sure your hand or other body parts are not in front of or to the side of the fastener's intended path. Nails especially have been known to hit hard objects, like knots or difficult grain, and shoot out the side of a workpiece. 7. Use extra caution when driving a fastener close to an edge to prevent the fastener from splitting the work, flying away, or hitting your hand. 8. Do not attempt to angle a nail or staple into the work surface more than about 10°; more than that may cause the fastener to ricochet off the work. 9. Pull the trigger lightly. A heavy pull may result in the gun driving two nails. 10. Before loading or unloading nails into the magazine, make sure the magazine is completely empty, then load the fasteners. Failure to do so may result in misfire, damage to the tool, or a fastener too long for the job. 24 of 33 Lathe Most Likely Uses 1. Making round or cylindrical shapes out of wood. Its primary components are the bed, headstock, tailstock, and tool rest. The work is rotated using a motor in the headstock; various tools are used at the tool rest to shape the work. The tailstock is used to support longer work at the opposite end of the bed. The lathe can be used to make a variety of turned objects, including table or chair legs, spindles, goblets, and bowls. Lathe Safety 1. Always wear a face shield and eye protection when operating the lathe. 2. Remove or fasten any loose clothing and roll sleeves above your 25 of 33 25 elbows. Tie long hair up and back. 3. Be sure belt covers are in place and closed. 4. Keep the floor where you are standing clear of chips to provide good footing. 5. Make sure the stock is free from checks, loose knots, or other defects. 6. Make sure the stock is correctly mounted on the lathe. 7. For faceplate turning, carefully select the screws used to secure the work. The screws must be properly sized for the design; they must not contact the cutting tools while you are working. Use a screw in every hole provided in the faceplate. 8. Make sure all screws are tight and check them occasionally. 9. Clamp the tool rest holder and tool rest firmly. Make adjustments to the tool rest only when the lathe is at a complete stop. 11. Keep the tool rest as close as reasonably possible to the stock by frequently stopping the lathe and adjusting the tool rest. 10. 26 12. Adjust the tool rest height so the cutting edge of the tool is at or just below the center of the work piece. 13. Before turning on the lathe, rotate the stock at least one full revolution by hand to make sure it clears the tool rest and all parts of the lathe. 14. Always hold the turning tool firmly against the tool rest. 15. Remove the tool rest when sanding, polishing, or finishing the workpiece. 16. Use a tailstock with a bearing center (live center) whenever possible. 17. Adjust the tailstock center so that the point is firmly embedded in the stock without impeding free rotation. 18. Run the lathe at slow speed when beginning any turning operation. When the stock is balanced and does not vibrate the speed may be increased. 19. If the lathe vibrates, it is running too fast or the stock is not properly secured. Stop the lathe and correct the problem. 26 of 33 20. The speed selector on a variable speed lathe must be operated only while the lathe is turning. A variable speed lathe does not have a belt which is moved between different sized pulleys to change the speed; it typically has a knob or handle on the front that can be rotated. 21. Stand to the side when starting the lathe. 22. Keep your hands away from the stock while it is rotating. 23. Keep your tools sharp since dull tools are harder to control and leave a rough surface on the work. 24. Stop the lathe to make measurements with calipers. 25. When polishing use a small rag folded in a pad, not wrapped around your finger. 26. Sand and polish only on the underside of the work. 27. A dust mask is recommended when sanding, especially with exotic or spalted woods. 28. Cut faceplate stock round on the band saw before mounting on the faceplate. 29. Allow glued stock or mounting blocks to cure at least 24 hours before using. 30. On faceplate turnings keep an accurate check on cutting depth to avoid striking the mounting screws. 27 of 33 27 Shaper CreatorSpace does not have this tool available at this time. 28 28 of 33 Hand Held Drills Most Likely Uses 1. Drilling holes and driving screws Hand Held Drill Safety 1. Select the correct drill or bit. Mount it securely to the full depth of the chuck. 2. Either clamp a scrap piece under work to prevent splintering the underside, or drill from both sides. 3. Stock to be drilled must be held in a stationary position so it cannot be moved during the operation. 4. Connect the drill to a properly grounded outlet. 5. Turn on the switch for a moment to see if the bit is properly centered and running true. 6. With the switch off, place the point of the bit in the punched layout hole. 7. Hold the drill firmly in one or both hands and at the correct drilling angle. 8. Turn on the switch and feed the drill into the work. The pressure required will vary with the size of the drill and the kind of wood. 9. During the operation, keep the drill aligned with the direction of the hole. 10. When drilling deep holes, especially with a twist drill, withdraw the drill several times to clear the shavings. 11. Unplug corded drills when changing drill bits or drivers. 12. Always keep corded drill power cords away form the drill bit 13. Follow the same precautions and procedures as when drilling holes with the drill press. 29 of 33 29 Circular Saw Most Likely Uses 1. Cutting plywood. Kickback Circular saw kickback occurs when the blade is pinched causing the tool to be thrown up and out of the piece of wood toward the operator. To avoid circular saw kickback: • Always hold the saw firmly with both hands. • Release the switch immediately if the blade binds or the saw stalls. • Never remove the saw from a cut while the blade is rotating. • Support large panels so they will not pinch the blade. Circular Saw Safety 1. Stock must be supported in such a way that the kerf will not close and bind the blade during the cut or at the end of the cut. 2. Thin materials should be supported on benches. Small pieces should be clamped in a vise or onto a bench top or sawhorse. 3. Be careful not to cut into the bench, sawhorse, or other supporting devices. 4.
