Spiral Cutterhead
The Model G9860ZX is equipped with a spiral cutterhead. The indexed square carbide cutters have four separate cutting surfaces that can be rotated as needed. If one of the cutters becomes damaged or dull, rotate the cutter to reveal the fresh cutting surface. Each edge of the indexed cutter is marked for easy identification. When an indexed cutter needs to be replaced, please order part #H2334 from the current Grizzly catalog.
Outfeed Table
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 knife edges. If the outfeed table is set too high, the board will hit the front edge of the outfeed table and will be impossible to feed over the join- ter. If the outfeed table is set too low, the trailing end of the board will fall into the cutterhead and snipe will occur.
1.Rotate the cutterhead by turning the motor pulley. DO NOT grab the cutterhead itself. Bring a knife edge to the approximate apex of its arc. Engage the brake rod to securely posi- tion the cutterhead.
2.Loosen the outfeed table lock knob located on the center of the outfeed table handwheel. Rotate the outfeed table handwheel until the outfeed table is nearly flush with the knife edge.
3.Position a steel straightedge on the outfeed table. Extend the straightedge over the middle of the cutterhead as shown in Figure 12.

4.Raise or lower the outfeed table with the out- feed table handwheel until the straightedge barely touches the knife edge. Rock the cut- terhead to ensure that the blade edge is at the highest point of its arc. Check the other two blades in the same manner. If they do not 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.Tighten the outfeed table lock knob.
6.Recheck the outfeed table alignment with each of the cutterhead knives and re-adjust as necessary.
7.Once properly set, the outfeed table height will only need to be changed when the knives are resharpened.
