9.3Setting Infeed Table Height (Depth of Cut)
1.To set the cutting depth, loosen handwheel (A, Figure 17) by turning counterclockwise.
2.Move table adjustment arm (B, Figure 17) up or down to raise or lower infeed table. The pointer (C, Figure 17) shows the depth of cut on the adjoining scale.
3.Tighten handwheel securely (A, Figure 17).
The stop screw (D, Figure 17) on the infeed table should be set so that when it contacts the table, the infeed table will be exactly level with the knives (with the scale pointer at zero). The setting of this stop screw has been made at the factory, but should be checked by the operator before using the jointer. It should also be checked occasionally as the machine receives use.
Use the same procedure as for the outfeed table, placing the straightedge across outfeed table, cutterhead and infeed table. Loosen the hex nut (E, Figure 17) and adjust the stop screw (D, Figure 17) as necessary. When finished, retighten hex nut (E, Figure 17).
If the infeed table is level with the knives but the scale pointer (C, Figure 17) appears to be off, loosen the scale pointer with a screwdriver and adjust it as needed until it reads zero. Retighten the screw.
9.4Replacing and Setting Knives (Straight Cutterhead)
Jointer knives are very sharp. Use care and proceed slowly when working with or around the cutterhead.
After a period of use, dull knives should be reground or replaced. Remove the pulley cover at the rear of the machine – this will allow you to rotate the cutterhead by using the belts.
To remove a knife:
1.Disconnect machine from power source.
2.Back the fence away from the cutterhead as far as it will go. Lower infeed and outfeed tables.
3.Turn the six gib screws (Figure 18) into the gib with a 10mm wrench. As the pressure of the gib is released, the two springs in the cutterhead slot will cause the knife to rise.
4.Carefully remove the knife from the cutterhead.
