head. See Figure 10.
4.While holding the knife setting gauge with one hand so it sits firmly on the cutterhead,
turn the tightening bolts counterclockwise with the other hand. Tighten the seven bolts until they begin to contact the side of the groove. Then tighten further, starting with the bolts at the center and working toward the outer ones. Once they are tight enough to hold the knife in position, remove the gauge.
5.Do a final tightening of each bolt. Recheck with the setting gauge to make certain the knife did not move. The knife tip should be just touching the top of the arc of the gauge as shown in Figure 10.
6.Repeat Steps 1 through 5 above to set the second knife.
7.Remove all tools and install chip deflector.
Make sure the G8794 is unplugged or discon- nected from the power source and moving parts have come to a complete stop before investigating any problems or performing any maintenance or adjustments. Serious person- al injury may occur.
The cutterhead knives on the G8794 planer are extremely sharp. Merely brushing your finger along the edge can result in a severe cut. Take extreme caution when doing any adjustments involving the cutterhead knives. Wear thick gloves anytime it is necessary to manually rotate the cutterhead assembly.
NOTICE
Never run the planer with only one knife installed in the cutterhead. This will cause a severe imbalance condition at the high speed at which the cutterhead rotates. Always install both knives and make certain they are tightly secured. When resharpening, always have both knives sharpened as a set.
