Infeed Table Stop

Bolt

The infeed table has a stop bolt that can be set to limit the how much the infeed table can be low- ered (see Figure 57). We recommend that this stop bolt be set for the recommended maximum depth of cut specified for your jointer.

Rotating/Replacing Cutterhead Inserts

The spiral cutterhead is equipped with indexable carbide inserts that can be rotated to reveal any one of their four cutting edges. If one edge of the insert becomes dull or damaged, simply rotate it 90° to reveal a fresh cutting edge, as shown in Figure 58.

To rotate or replace a spiral cutterhead
insert:

1.DISCONNECT JOINTER FROM POWER!

2.Put on heavy leather gloves to protect your fingers and hands.

3.Remove any sawdust or debris from the head of the insert, Torx screw, and the surrounding area.

4.Remove the Torx screw and the insert, then clean all dust and debris from both parts and the pocket they were removed from.

Note: Proper cleaning of the insert, Torx screw, and the cutterhead pocket is critical to achieving a smooth finish. Dirt or dust trapped between the insert and cutterhead will slightly raise the insert, and make noticeable marks on your workpiece the next time you cut.

Tip: Use low-pressure compressed air or a vacuum nozzle to clean out the cutterhead pocket.

5.Replace the insert so that a fresh cutting edge faces outward.

—If all four insert cutting edges have been used, replace it with a new one. Always position the reference dot in the same posi- tion when installing a new insert to aid in the rotational sequencing.

6.Lubricate the Torx screw threads with a small amount of light machine oil, wipe the excess off, and torque the screw to 50–55 inch/ pounds.

Note: If you use the included air pressure torque wrench, refer to the detailed instruc- tions on the next page for its use.
