Setting/Replacing
Knives
Planer knives are extremely sharp and can quickly cause a serious injury to your hands or fingers. Always wear heavy leather gloves when handling these knives to reduce the risk of cutting injuries.
Setting the height of the knives correctly is cru- cial to the proper operation of your planer and is very important in keeping the knives sharp. If one knife protrudes higher than the others, it will do the majority of the work, dull much faster, and produce poor cutting results.
The knife gauge that is included with the Model G0453/G0454 is designed to set the knives 0.059" higher than the cutterhead surface.
Note: If you need to replace or sharpen a knife, you can remove the knife from the cutterhead dur- ing Step 4 of the following procedure. Thoroughly clean out any debris from the knife slots before replacing the knives.
Replacement knives are available through Grizzly (refer to Page 28 for options).
