Knife Replacement

The cutterhead knives on the Model G0663 are extremely sharp. Brushing your finger along the edge can result in a severe cut. Take extreme caution when doing any of the adjust- ments involving the cutterhead knives. Wear thick gloves anytime it is necessary to manu- ally rotate the cutterhead assembly.

The condition of the knives on the Model G0663 Planer will affect the precision of the cut. During operation, watch for the following signs of dulled knives.

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

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

Grooves as a result of nicks along the knife edge.

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

To remove the knives:

1.DISCONNECT PLANER FROM POWER!

2.Remove the cap screws from the knife guard, then remove the guard (Figure 19).
