ADJUSTMENTS guard open. -19 Depth Of Cut The depth of cut is equal to the distance between the infeed table surface and the top of the cutterhead blade at top-dead-center (Figure 28). The depth of cut is adjusted by raising and lowering the infeed table. To adjust the depth of cut: • Turn the table height knob (Figure 29) clockwise to raise the infeed table, thereby reducing the depth of cut. • Turn the knob counter-clockwise to lower the infeed table, thereby increasing the depth of cut. Never remove more than 1.8" of material from the workpiece in a single pass. Depth Of Cut Figure 28. Depth of cut. Figure 29. Table height knob. ADJUSTMENTS -20 Blade Guard The blade guard protects the operator from the cutterhead blades. It must be functioning correctly before performing any jointing operation. To make sure the blade guard is functioning correctly, do these steps: 1. UNPLUG THE JOINTER! 2. Adjust the infeed table even with the out- feed table. 3. Slide a piece of wood across the jointer as if performing an actual jointing operation. • The blade guard should rotate enough to allow the wood to pass over the cutter- head (Figure 30). • Once the wood has passed over the cutterhead, the blade guard should swing completely back over the cutterhead. 4. Swing the blade guard completely open and release it. • The blade guard should swing completely back over the cutterhead. Figure 30. Blade guard in use. ADJUSTMENTS -21 OPERATIONS OPERATIONS OPERATIONS Test Run Once assembly is complete, the machine is ready for a test run. The purpose of a test run is to identify any unusual noises and vibrations, as well as to confirm that the machine is performing as intended. To test run the Model W1694, do these steps: 1. Make sure that all tools have been removed from the jointer. 2. Turn the jointer ON. 3. Once the jointer is running, listen for any unusual noises. The machine should run smoothly with little or no vibrations. • If there are any unusual noises or vibrations, stop the jointer immediately by pushing the paddle switch down. 4. Unplug the jointer and investigate the source of the noise or vibration. DO NOT make any adjustments to the jointer while it is plugged in. The jointer should not be run any further until the problems are corrected. THIS MACHINE throws wood chips and sawdust. Wear safety glasses or a face shield during all operations. KEEP loose clothing rolled up and out of the way of machinery and keep hair pulled back. THIS MACHINE produces sawdust that may cause allergic reactions or respiratory problems. Wear a dust mask or respirator in addition to using a dust collector. -22 Operation Requirements • Never allow hands or push blocks to come within 4" of the cutterhead while it is moving. • Carefully inspect boards before jointing. Defects such as twisting, knots, or cracks could cause the workpiece to break apart. • Only use clean boards. Remove all dirt, nails, staples, imbedded gravel, etc. from boards before jointing. Dirt and debris can damage the cutting edge of the cutterhead blades, resulting in unsatisfactory results. • DO NOT joint man-made products such as MDF, OSB, or plywood. Also, never use laminates, formica or other synthetic materials. • Always joint “with” the grain. Cutting “with” the grain is best described as feeding boards on the jointer so the grain points down and toward you as viewed on the edge of the workpiece (Figure 31). • Avoid using wood with a high moisture content. Boards with more than 20% moisture will cause unnecessary wear on the cutter- head blades and motor. • Never take cuts deeper than 1.8". Making several shallow cuts will produce a better finished result than one deep cut. • Keep work area clean and free of clutter. Figure 31. Correct and incorrect grain alignment to cutterhead. OPERATIONS -23 OPERATIONS Surface Planing Surface planing flattens the concave face of the workpiece in preparation for surface planing on a thickness planer (Figure 32). The flat face allows the thickness planner to produce a work- piece that is flat and uniformly thick. Figure 33 shows an example of an operator using the jointer to surface plane a workpiece. Notice that the operator’s body is not directly behind the workpiece and that the operator is using push blocks. To perform a surface planing operation, do these steps: 1. Read and become familiar with the Operation Requirements sub-section. 2. Place the workpiece so the concave side is down on the infeed table and press the workpiece firmly against the fence. 3. Start the jointer. 4. Using push blocks, feed the workpiece through the jointing operation. Make sure to maintain even downward pressure. 5. When your leading hand gets within 4" of the cutterhead, lift the push block up and over the cutterhead and place it on the workp...
