Knife Replacement

The cutterhead knives on the Model G0689 are extremely sharp. Brushing your finger along the edge can result in a severe cut. Take extreme caution when doing any of the adjustments involving the cutterhead knives. Wear heavy leather gloves any- time it is necessary to manually rotate the cutterhead assembly.

To maintain accurate and consistent plan- ing results, we do not recommend sharpen- ing the knives. Instead, replace both knives when they get dull.

The condition of the knives on the Model G0689 Planer will affect the precision of the cut. During operation, watch for the following signs of dulled knives.

•Raised grain occurs as a result of dull knives hammering at the surface of the wood.

•A "fuzzy" appearance on the surface of the wood occurs as a result of dull knives tearing, rather than cutting the wood fibers.

•Grooves occur as a result of nicks along the knife edge.

•Difficulty feeding the workpiece into the planer.

If any of these signs become apparent during use, the knives must be reversed or replaced. Do not attempt to sharpen the knives.
