Surface Planing
The purpose of planing on a jointer is to produce one flat surface. The theory behind this is that once you have one flat surface on a board, it can then more readily be milled to precise, final dimensions on a thickness planer. It is nearly impossible to surface plane both sides of a board effectively because the two surfaced sides will not be parallel to each other.
1.Inspect your lumber for soundness and grain direction.
2.If the stock is cupped (warped), place the concave side down and slowly feed it over the cutterhead. See Figure 27.
Always use push paddles when planing the surface of a board. Failure to comply may result in serious personal injury.

3.Inspect your results. Most likely, many pass- es will be necessary before your lumber has a flat surface.
4.If the stock has large or loose knots, consid- er finding another workpiece. Knots in a workpiece can be dangerous to the operator, as well as destructive to equipment.
Rabbet Cuts
A rabbet is a groove cut along the edge of a board. It is usually made to accept another board to form a strong, simple joint. Note: The maxi- mum rabbet depth is 1⁄2".
1.Unplug the jointer and remove the cutter- head guard.
2.Loosen the fence and slide it to the rabbeting edge. Set the fence to the desired width of the rabbet and lock down. For small rabbets, remove the fence sliding locking lever and reinsert it in the rear fence hole on the fence base.
3.Inspect stock for soundness and grain direc- tion.
4.Place stock on the infeed table and rabbet table with the edge to be rabbeted firmly against the fence.
5.Slowly and evenly feed stock through the cutterhead. Using the 1⁄16" rule, it will take six passes to achieve a common 3⁄8" rabbet. See
Figure 28.
6.Replace the guard when finished with rab- beting operations.
