6.Carefully remove the knife and gib.

7.If the knife is dull or damaged, replace it with a new one.

8.Clean the knife, gib, and inside the cutterhead slot to remove all the pitch or sawdust. Coat the knife and gib with a metal protectant (refer to Page 32), then fit the gib back into the cutterhead with the knife.

9.Make sure the beveled side of the knife is against the cutterhead, as shown in

Figure 61.

10.Position the straightedge on the outfeed table and over one end of the knife, then use magnets or an assistant to make sure the straightedge stays in full contact with the outfeed table along its full length.

11.Insert the 3mm hex wrench through the access holes in the cutterhead, then rotate the jack screws to raise or lower the knife (see Figure 62). When the knife is set correctly, it will just touch the bottom of the straightedge without lifting it.
