Now is a good time to double-check the knife settings. To inspect and adjust knife set: 1. Unplug the jointer! 2. Remove the upper cover or cutterhead guard to expose the top of the cutterhead. 3. Carefully turn the cutterhead (using the pulley) until the first knife is at top dead center. 4. Using the knife setting gauge, check the knife height. The jig should sit solidly with both feet on the cutterhead. See Figure 15. If the knife is adjusted properly, the contact point at the center of each adjuster should just touch the tip of the knife. If the knife does not make contact, or if the knife causes the adjuster’s legs to not seat on the cutterhead, the knives need to be adjusted. Remember, jointer knives are extremely sharp. Use care when handling during removing or installing. Knife Setting Gauge Jack Screws Springs Figure 15 shows the location of the springs should you decide to use them instead of jack screws. ADJUSTMENTS USING JACK SCREWS When using jack screws, it is not necessary to install the springs. The knives are locked into the cutterhead with wedge-type gibs and gib bolts. Jack screws under the knives allow fine tuning to help in the setting process. To realign the knives: 1. Unplug the jointer! 2. Loosen the gib bolts until the knife is loose in the slot. The gib bolts turn clockwise to loosen and counterclockwise to tighten (when facing the head of the bolt). See Figure 16 and 16B. 3. Place the knife setting gauge on the cutterhead as described previously, so the feet are securely planted on the cutterhead. 4. Adjust the screws below each end of the knife until both feet of the gauge rest evenly on the cutter- head and the knife is just touching the bottom of the middle foot of the gauge. The gauge will set the knives at a uniform protrusion of approximately .070" above the cutterhead. The knife height should vary no more than .002"-.003" across the length of the cutterhead. 5. Maintain a constant pressure on the gauge while retightening the gib bolts. 6. Repeat the same procedure on the remaining knives. As mentioned before, the standard knife setting gauge is satisfactory for reasonably accurate knife setting tasks.

The knives are locked into the cutterhead with wedge- type gibs and gib bolts. Jack screws under the knives may be substituted with springs to help in the setting process. When using springs, it is advised that the jack screws be removed. To realign the knives: 1. Unplug the jointer! 2. Loosen the gib bolts until the knife is loose in the slot. The gib bolts turn clockwise to loosen and counterclockwise to tighten (when facing the head of the bolt). Remove the knife and jack screws. Place 1 spring in each of the two holes in bottom of the knife slot. See Figure 16A and 16B. 3. Place the knife setting gauge on the cutterhead as described previously, so the feet are securely planted on the cutterhead. Make sure the gauge extension rod is parallel to the cutterhead to maintain accuracy. 4. The downward pressure provided by the gauge will set the knives at a uniform protrusion of approximately .070" above the cutterhead. The knife height should vary no more than .002"-.003" across the length of the cutterhead. 5. Maintain a constant pressure on the gauge while retightening the gib bolts. 6. Repeat the same procedure on the remaining knives. As mentioned before, the standard knife setting gauge is satisfactory for reasonably accurate knife setting tasks.

Outfeed Table NOTICE Model G1182HW uses handwheels for out- feed and infeed table adjustments. Facing the fence, the outfeed table is located to the left of the cutterhead. The outfeed table must be aligned to the highest point of the arc of the blades. If it is set too high, the board will hit the front edge of the table and be impossible to feed over the jointer. If the table is set too low, the back end of the board will fall into the cutterhead and snipe will occur. 1. Loosen the table stop bolt jam nut under the outfeed table. Turn the table stop bolt counter-clockwise several times so that it will not interfere when setting the correct table height. See Figure 17. 2. Rotate the cutterhead by turning the motor pulley. DO NOT grab the cutterhead itself. Bring one blade to the approximate apex of its arc. 3. Position a steel straightedge on the outfeed table. Extend the straightedge over the middle of the cutterhead. See Figure 18. -19 Figure 17. Table stop bolt and check nut. all touch the straightedge evenly, they are not at the same height. You must reset the knives. Be sure to test the height at both ends of the cutter knives. The knives must be parallel to the table surface. 5. Adjust the stop bolt until it touches the cast base...
