Figure 10. Cutterhead guard.
To adjust the cutterhead guard:
1.Unplug the power from the machine!
2.Lay the Model H2801 on its back so the switch is facing up.
3.Remove the screw from the base where it secures the cutterhead guard.
4.Slide the cutterhead guard off the jointer.
5.Position the cutterhead guard so that the long arm of the spring is against the cutter- head guard wall. Secure the cutterhead guard with the screw.
6.Check the cutterhead guard to make sure it functions properly.
If the cutterhead guard still does not function properly, the spring may need to be replaced. For replacement instructions, turn to the Section 6: Maintenance.
Disconnect power to the machine when perform- ing any adjustments or maintenance. Failure to do this may result in seri- ous personal injury.
Knife Adjustment
To ensure accurate cutting, the knives must be
.003" higher than the outfeed table at the highest point. To check or adjust the knife height:
1.Unplug the power from the machine!
2.Block the cutterhead guard from closing with a scrap piece of wood between the fence and the cutterhead guard, or remove the cut- terhead guard.
3.Rotate the cutterhead so that one of the knives is at the highest position.
4.Place a straightedge over the outfeed table and the knife, so it evenly touches the out- feed table at both ends of the knife. Rotate the cutterhead slowly to see if the knife bare- ly touches the straightedge. Check the knife height at each end of the knife.
5.If the knife raises the straightedge, loosen the knife clamp screws and gently tap the knife with a small piece of wood. If the knife does not touch the straightedge, loosen the knife clamp screws and carefully pry the knife up from the bottom edge with a flat- head screwdriver. See the diagram in Figure 11 to identify the cutterhead parts.
6.Properly align both ends of the knife with the outfeed table and tighten the knife clamp screws. Recheck the knife alignment after the screws are tight and adjust if necessary.
