Cutterhead Knives

The Model G9740/G9741/G9967 features a 4- knife cutterhead. The knives are factory set to

.071". Unless you are having problems related to the knives or are removing them for sharpen- ing/replacement, assume that your knives are adjusted correctly. To be safe, always test the planer with a scrap piece of wood before using expensive stock.

When adjusting, make adjustments accurate to within ±.001" from one side to the other. Improperly adjusted knives can unbalance the cutterhead and shorten the bearing life, as well as produce substandard planing results.

Planer knives are danger- ously sharp! Use extreme caution when working near cutting surfaces. Failure to exercise care while working near knives could result in severe injury.

To inspect the knife set:

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

2.Open the top cover to gain access to the cutterhead. Lock the cutterhead in place with the cutterhead lock as shown in Figure

3.Remove the hex nuts and springs from the tension studs shown in Figure 8. This will allow the pressure bar to rotate up and over the cutterhead.

4.Remove the four bolts that attach the pres- sure bar to the eccentric ring.

5.Without bumping the knife edge, carefully take the pressure bar out of the planer. You can now access the cutterhead with the knife setting jig.

6.To prepare the knife setting jig, back all four of the screws out of the feet. Adjusting one screw at a time, set the screw even with the surface of the jig foot. Turn the screw exactly 21⁄2" turns (this is approximately .071"), or measure this distance with a caliper. Tighten the check nut, making sure that the screw does not move. Adjust the other three screws by using this same procedure.

7.Place the jig on the cutterhead. If the knife is adjusted right, the feet should touch the cutterhead body on both sides of the knife, and the knife should barely touch the jig.

8.Repeat this inspection for the other two knives.

To adjust the knife set:

1.Before beginning, make sure you have fol- lowed steps 1-6from the knife inspection instructions above!

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