Anleitung Zusammenfassung
Proceed as follows: 6. Rotate the cutterhead (using the pulley) until the tip of the knife is at the top of the cutterhead arc. Place the knife setting gauge (Figure 17) over the cutterhead so the tip of the knife contacts the center of the gauge, and all four "feet" of the gauge rest firmly upon the cutterhead, as the knife is pushed down into its slot. The gauge will set the knives at approximately .070" above the cutterhead. Knife height should not vary more than .002-.003" across the length of the cutterhead. Figure 15 Figure 16 Figure 17 13 7. Tightening the gib screws should be done in increments, to prevent any distortion to the cutterhead or buckling of knives. While holding the gauge down on one knife, snug down the five gib screws, beginning with the center screw and working your way to the ends. Do not fully tighten yet. 8. Rotate the cutterhead to the next slot and repeat step #6, only making the knives snug. Repeat for the third knife. 9. The tightening process should continue at least two more times, each time tightening the screws more on all three knives. On the third time, they should all be firmly tightened. Before starting jointer, make sure all gib screws are firmly tightened. A loose knife thrown from the cutterhead can cause severe or fatal injury. 10. After replacing knives, the outfeed table must be checked and adjusted so that it is level with the high point of the knives. See “Setting Outfeed Table” on page 16. Leveling Tables The tables have been leveled with each other from the factory, but this should be confirmed by the user, and checked periodically, by placing a steel straight edge across both tables. If tables are not level, this may be the result of loose gibs. Correct as follows: 1. Loosen hex nuts on the gib screws (A, Figure 18) with a 12mm wrench, then loosen the gib screws with a 4mm hex wrench. Loosen the table lock handle (B, Figure 18). 2. Remove lower hex nut and gib screw (A*, Figure 18) and check screw hole to make sure that punch mark in the gib is aligned with the screw hole. If punch mark is not visible, or it does not line up with screw hole, use a screwdriver to lightly tap the gib back into alignment. 3. Replace the lower gib screw (A*, Figure 18) but do not tighten. 4. Carefully tighten the table lock screw (B, Figure 18). The table will begin to move toward the straight edge. 5. When aligned, re-set the gib screws (A, Figure 18) until tight. If table does not align with straight edge, use the adjusting arm (C, Figure 18) for the infeed table, or handwheel (D, Figure 18) for the outfeed table, until the table is flush with the straight edge. Figure 18 14 6. Tighten the gib screws (A, Figure 18) then back them off approximately 1/4 turn or until the table moves freely, and re-set the lock nuts on the gib screws. If table will still not line up: Remove gib screws and table locking handle and remove gib (#16, page 29). Check gib to see that set screws do not go all the way through the gib or dimple the opposite side. If either of these conditions exist, replace with a new gib. Also, check to be sure the ways are clean and free of pitch and sawdust. Lubricate gib and way with a good grade of non-hardening grease. Replace the gib, making certain that the punch mark lines up with the locking screw holes. Replace gib screws. Repeat steps 3 through 6. Adjusting Depth of Cut Depth of cut is determined by the height of the infeed table relative to the cutterhead. Setting the infeed table is achieved with both a rapid adjust and a fine adjust. Rapid Adjust: 1. Loosen the lock screw (A, Figure 19) and the locking handle (B, Figure 19). 2. Raise or lower the height adjustment handle (C, Figure 19) until the scale (D-Figure 19) reads approximately the correct depth of cut. Fine Adjust: 3. Rotate the locking handle (B, Figure 19) until it is snug, then fine-tune the adjustment by rotating the height adjustment handle (C, Figure 19) until the scale reads exact. (Clockwise raises the table, counterclockwise lowers the table.) A full rotation of the fine adjustment handle equals 1/16" travel of the infeed table. 4. When set, re-tighten lock screw (A, Figure 19). Periodically check the accuracy of the depth of cut scale (D, Figure 19) by raising the infeed table until it is flush with the peak of the cutterhead arc (using a straight edge across table and cutterhead). The scale should read zero depth. If it does not, re-adjust the pointer above the scale. Figure 19 15 Setting Outfeed Table For accurate work in most jointing operations, the outfeed table must be exactly level with the knives at their highest point of revolution. 1. Raise the outfeed table to its highest point, and place a straight edge across it. 2. Rotate the cutterhead (using the belt or pulley) until one knife is at its highest point. 3. Lower the outfeed table until the straight edge contacts a knife. Rock the cutterhead slightly to make sure the apex of the knife is contacting the straight edge. Lock the ...
