Operation
The DeWalt DWE7491 table saw is designed for a variety of woodworking tasks, including ripping, crosscutting, bevelling, and mitreing. Before operating the saw, ensure you have read and understood all safety precautions outlined in the manual. Always wear appropriate safety gear, including eye protection, hearing protection, and work gloves. When cutting wood, feed the material slowly and steadily, keeping your fingers clear of the blade. Use a push stick or feather board to guide the workpiece and prevent kickback. Never attempt to cut materials that are too large or heavy for the saw’s capacity. Regularly inspect the saw for any signs of wear or damage, and replace or repair any faulty parts promptly.
Ripping
Ripping involves cutting wood along the grain to create a straight, parallel edge. To rip a piece of wood, position the fence parallel to the blade and adjust its distance to achieve the desired width. Ensure the workpiece is securely clamped to the table and positioned against the fence. Use a push stick to guide the wood through the blade, maintaining constant pressure against the fence. Always feed the wood slowly and steadily, ensuring the blade remains in contact with the workpiece. If the wood binds or jams, stop the saw immediately and release the pressure. Never attempt to force the wood through the blade, as this can lead to kickback and injury.
Crosscutting
Crosscutting refers to cutting wood perpendicular to the grain. To perform a crosscut, position the workpiece against the miter gauge, ensuring it is securely clamped. Adjust the miter gauge to the desired angle, if necessary. Align the workpiece with the blade, ensuring it is perpendicular to the blade path. Use the miter gauge to guide the wood through the blade, maintaining constant pressure against the gauge. Feed the wood slowly and steadily, ensuring the blade remains in contact with the workpiece. Never attempt to force the wood through the blade, as this can lead to kickback and injury. Always use a push stick to guide the wood through the blade, especially when crosscutting large pieces of wood.
Bevelling
Bevelling involves cutting wood at an angle other than 90 degrees. To bevel a piece of wood, loosen the bevel lock lever and adjust the blade angle using the bevel scale. Tighten the bevel lock lever to secure the blade at the desired angle. Ensure the workpiece is firmly clamped to the table, and align the blade with the edge of the wood. Guide the wood through the blade using the miter gauge or rip fence, depending on the desired cut. Always maintain constant pressure and feed the wood slowly and steadily to avoid kickback and ensure an accurate cut.
Mitreing
Mitreing involves cutting wood at an angle to create a joint, typically used for framing or joining pieces at an angle. To mitre a piece of wood, adjust the miter gauge to the desired angle. Align the edge of the wood with the miter gauge and ensure the workpiece is securely clamped to the table. Slowly guide the wood through the blade, maintaining constant pressure and a steady feed rate. When cutting miters, it is crucial to ensure the miter gauge is properly aligned and locked in place to avoid inaccurate cuts. Use a push stick or miter gauge hold-down to safely guide the wood through the blade, especially when cutting smaller or narrower pieces.
