It is also a necessary step prior to ripping stock to width on a table saw or radial arm saw. 1. Make sure the fence is set to 90°. Double check it now with a try square or machinist’s square. 2. Inspect stock for soundness and grain direction. 3. If the board is bowed (curved), place the concave edge down on the infeed table. 4. Holding the stock firmly against the fence and table, feed the stock slowly and evenly over the cutterhead. See Figure 25. Figure 25. Operator position for edge jointing. Beveling an edge is essentially the same operation as edge jointing, except that the fence is tilted to a specified angle. Use extra care to ensure that the edge makes solid contact with the infeed and outfeed tables at all times. 1. Use a bevel gauge to determine the desired angle. Then use the bevel to transfer this angle to the fence. 2. Tilt the fence by loosening the lock handle and moving the fence to the desired angle. 3. Inspect stock for soundness and grain direction. 4. Slowly and evenly feed stock through the cutterhead. Make sure the face of the stock is completely flat against the fence and the edge is making solid contact on the infeed and outfeed tables. See Figure 26. 5. Achieving the full bevel will probably take several passes. Remember not to take more than 1.16" in one pass. Figure 26. Fence position for bevel jointing. -24- G1182 6" Series Jointers Surface Planing The purpose of planing on a jointer is to produce one flat surface. The theory behind this is that once you have one flat surface on a board, it can then more readily be milled to precise, final dimensions on a thickness planer. It is nearly impossible to surface plane both sides of a board effectively because the two surfaced sides will not be parallel to each other. 1. Inspect your lumber for soundness and grain direction. 2. If the stock is cupped (warped), place the concave side down and slowly feed it over the cutterhead. See Figure 27. Always use push paddles when planing the surface of a board. Failure to comply may result in serious personal injury. Figure 27. Correct method for surface planing. 3. Inspect your results. Most likely, many passes will be necessary before your lumber has a flat surface. 4. If the stock has large or loose knots, consider finding another workpiece. Knots in a workpiece can be dangerous to the operator, as well as destructive to equipment. Rabbet Cuts A rabbet is a groove cut along the edge of a board. It is usually made to accept another board to form a strong, simple joint. Note: The maximum rabbet depth is 1.2". 1. Unplug the jointer and remove the cutter- head guard. 2. Loosen the fence and slide it to the rabbeting edge. Set the fence to the desired width of the rabbet and lock down. For small rabbets, remove the fence sliding locking lever and reinsert it in the rear fence hole on the fence base. 3. Inspect stock for soundness and grain direction. 4. Place stock on the infeed table and rabbet table with the edge to be rabbeted firmly against the fence. 5. Slowly and evenly feed stock through the cutterhead. Using the 1.16" rule, it will take six passes to achieve a common 3.8" rabbet. See Figure 28. 6. Replace the guard when finished with rabbeting operations. Figure 28. Correct operator position for rabbet cutting. G1182 6" Series Jointers -25 SECTION 7: MAINTENANCE Tables Disconnect power to the machine when performing any maintenance, assembly or adjustments. Failure to do this may result in serious personal injury. The table and other non-painted surfaces on the Model G1182 should be protected against rust and pitting. Wiping the jointer clean after every use ensures that wood dust isn’t allowed to trap moisture against bare metal surfaces. Some woodworkers recommend using automotive paste wax on exposed steel and cast iron surfaces. The wax provides a layer of protection, as well as reducing friction between lumber and the table, making cuts faster and smoother. Avoid waxes that contain silicone or other synthetic ingredients. These materials can find their way into lumber that’s being worked, and can make staining and finishing difficult. If you use paste wax, make sure that it’s 100% Carnauba wax. Lubrication Since all bearings are shielded and permanently lubricated, simply leave them alone until they need to be replaced. Do not lubricate them. Table ways and the fence assembly should not be lubricated. If the tables appear to be stuck, disassemble and clean any foreign materials from the ways. Re-assemble and reset the gibs. V-Belt Inspect regularly for tension and wear; replace when necessary with a size A-36 belt. Check pulleys to ensure that they are properly aligned. See pulley/V-belt sections for proper tension and pulley alignment procedures. Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back. Wear safety glasses during the entire maintenance process. Failure to comply may result in serious personal injury. General Regular periodic maintenan...
