Figure 14. Adjusting knife height.

4.If the knife bottoms out on the gauge block, repeat steps 1, 2 and 3, but start on the oppo- site side of the cutterhead.

5.The variation between one side and the other should not be greater than 0.004". Repeat steps 1 through 4 on the other two knives. Again, the variation between all three knives should not be greater than 0.004"

Once you have completed inspection on all three knives, you will able to determine whether or not there is a need to adjust the knives in the cutter- head. The next set of instructions will address the process of setting the knives.

CAUTION

When making adjustments, all three knives must be adjusted the same. Do not adjust one knife without adjusting the others as well. Improper knife height adjustment can result in damage to knives, poor planer per- formance and possible operator injury.

Knife Setting

The process of setting the knives in the cutter- head will come into play whenever you sharpen or replace, or after determining that setting is necessary during the initial setup.

The knives are locked into the cutterhead with wedge type gibs. Springs under each knife pro- vide an upward pressure to help ease the setting process.

TO SET THE KNIVES:

1.Remove the upper cover to expose the cut- terhead.

2.Loosen the gib bolts securing the first knife just enough until the knife pushes upward.

3.Place the knife setting jig over the knife on the cutterhead as shown in Figure 15. The knife setting jig will push the knife into posi- tion in the cutterhead.
