Grizzly G9740 instruction manual Cutterhead

To check the table with the block of wood:

1.Make sure the planer is disconnected from the power source!

2.Models G9740Z and G9967Z skip this step. For Models G9740 and G9967, open the left side service door. Locate the cutterhead lock shown in Figure 11. Pull up and twist so the end of the lock will drop. Rotate the pulley to line up the cutterhead lock with the THREADED HOLE in the pulley (this should position the cutterhead so the knives are out of the way for table adjustments).

3.Place the block of wood on the table, under- neath the cutterhead. Position the block on the left side (point “A” in Figure 13) of the cutterhead.

Figure 13. Measure table-to-cutterhead at both

points “A” and “B.”

4.Raise the table up until the top of the block lightly contacts the bottom of the knife or indexable insert, depending on your model.

5.Without moving the table position, slide the block over to the other side (point “B” in Figure 13).

6.If the block will not fit under the cutterhead or if the gap between the block and the cutterhead exceeds .004" (use a feeler gauge to measure this), the table must be adjusted.

To adjust the table with the Rotacator®:

1.Make sure the planer is disconnected from the power source!

2.Set the Rotacator® dial to .000". Place the Rotacator® under the cutterhead on the right- hand side (facing front).

3.Turn the cutterhead so the plunger on the Rotacator® contacts the cutterhead body. Raise the table up enough for the cutterhead to get a reading on the dial.

4.Move the Rotacator® back and forth to find bottom dead center on the cutterhead. (You will reach bottom dead center when you have the highest reading on the Rotacator®.)

5.Adjust the table height to make the dial on the Rotacator® read .050", then set the dial to .000". Move the Rotacator® over to the far left end of the cutterhead and find bottom dead center.

6.Locate the two columns underneath the table. These are covered in flexible rubber sleeves. Underneath the sleeves are adjust- ment flanges that allow you to disengage the table columns from the lifting gears.

To adjust the table, you need to disen- gage the opposite side from that which needs to be adjusted.

7.Pull the rubber sleeve down on the deter- mined column to expose the table adjust- ment flange shown in Figure 14. You may need to cut the plastic cable tie in order to remove the sleeve.
