Wear safety glasses at all times. Outfeed Table To set the outfeed table: 1. Unplug the machine from the power source! 2. Open the access door on the back of the machine, just below the fence adjustments. 3. Turn the cutterhead pulley to position the knife or carbide cutter close to the highest point in its revolution. 4. Set a straightedge on the outfeed table so that it extends over the cutterhead (Figure 33). Figure 33. Setting the outfeed table. Outfeed Table Carbide cutter is at the highest point in its revolution and is just touching straightedge. 5. Rock the cutterhead back-and-forth, using the cutterhead pulley to position the cutter edge at the highest point in its revolution. 6. Loosen the outfeed table lock knob. 7. Turn the outfeed table handwheel to raise or lower the outfeed table until the carbide cutter or knife just touches the straightedge WITHOUT lifting it off the outfeed table. 8. Tighten the outfeed table lock knob. SECTION 8: SERVICE ADJUSTMENTS Knives (Model G9953 Only) Setting the knives correctly is crucial to the proper operation of the jointer and is very important in keeping the knives sharp. If one knife is higher than the others, it will do the majority of the work, and thus, dull much faster than the others. Note— The cutterhead knives should protrude above the cutterhead 2mm (0.079"). The knife jig included with the jointer is designed to set the knives within this height. To set the knives: 1. Unplug the machine from the power source! 2. Open the access door on the back of the machine, just below the fence adjustments. 3. Turn the cutterhead pulley until the surface of the cutterhead is at top dead center. 4. Adjust the outfeed table to a height of 2mm above the surface of the cutterhead. 5. Turn the cutterhead pulley to reveal one of the knives. 6. Loosen the cutterhead gib bolts, starting in the middle, and alternating back and forth until all of the gib bolts are loose, but not falling out (Figures 34 and 35). Note—The gib bolts turn clockwise to loosen and counterclockwise to tighten (when facing the head of the bolt). Tighten Loosen Knife Gib Bolt Gib Figure 34. Loosening the gib bolts. Figure 35.

Position the knife setting gauge on the out- feed table so that it extends over the cutter- head as shown in Figure 36, and loosen the gib bolts until the knife is completely loose. Outfeed Table Figure 36. Checking knife with the knife setting gauge. Knife Edge At Highest Point Of Rotation Knife Setting Gauge 8. Rock the cutterhead back-and-forth, using the cutterhead pulley to position the knife edge at the highest point in its revolution. 9. Using a 3mm allen wrench, find the jack screws through the access holes in the cutterhead and rotate the jack screws to raise or lower the knife. When the knife is set correctly, it will barely touch bottom of the knife setting gauge WITHOUT lifting the gauge off the outfeed table. Note—The knife height should be level with the outfeed table to within .002". A dial indicator can be used to check variation in thousandths of an inch; however, the knife setting gauge is an adequate setup instrument. 10. Snug the gib bolts tight enough to just hold the knife in place. 11. Repeat steps 5-10 with the rest of the knives. 12. Repeat step 10, but final tighten each gib bolt. Carbide Cutters (Models G9953ZX, G9953ZXF and G4815) The dot on each cutter is used as a reference point when determining which cutter edges are used, or dull, and which are sharp. Be sure to always rotate the cutters is the same direction as shown in Figure 37. Otherwise, the dot will not be an effective reference for determining which cutting surfaces are sharp. The carbide cutter dimensions are 14mm x 14mm x 2mm, with a 6.5mm bore and 30° relief angles. Reference Dot Figure 37. Always rotate carbide cutters in thesame direction to keep track of the dull ordamaged edges. The models with spiral cutterheads are supplied with an air wrench for loosening and tightening the carbide cutter Torx® screws. This tool is very valuable if you have to rotate or change many of the cutters at one time. T-20 Torx® bits are included. Installing or adjusting the carbide cutters: 1. Connect the air wrench to your regulated air compressor. 2. Adjust the air pressure (torque) setting dial on the side of the air wrench to the "2" position. Note—The "1, 2, 3" dial on the air wrench adjusts the torque, relative to the compressor air pressure. The "1" setting will produce the highest amount of torque possible at a given compressor air pressure, while the “3” setting will produce the least torque. 3. Install a T-20 Torx® bit into the air wrench. Ultimate Series Jointers -33 4. Sparingly oil the threads of the carbide cutter Torx® screws with a light machine oil. 5. Adjust the compressor air pressure to 30 PSI. Note—The low pressure (torque) setting will reduce the chance of cross threading the Torx® screw ...
