Always use a hold down or

Rabbeting
A rabbet cut requires removal
of the cutter guard. Use extreme caution and
keep hands clear of cutterhead. Always replace
guard immediately after rabbeting operation is
completed.
A rabbet is a groove cut along the edge of a board.
See Figure 22. The width and thickness of the
wood to be rabbeted depends upon the width and
length of the rabbet. However, never rabbet a
piece of wood less than 12” long.
Figure 22
Use push blocks to rabbet cut whenever possible.
The rabbeting capacity is 3/4”.
1. Disconnect machine from power source.
5. Set fence for desired width of rabbet.
6. Check width of the rabbet by measuring the
distance from end of knife in the cutterhead to
the fence.
7. Reconnect power. Lower infeed table 1/32” at
a time and make successive cuts until the
desired depth of rabbet has been obtained.
See Figure 22. NOTE: It is easier and safer to
take a series of shallow cuts.
Jointing Warped Surfaces
If the wood to be jointed is dished or warped, take
light cuts until the surface is flat. Avoid forcing
such material down against the table; excessive
pressure will spring it while passing the knives, and
it will spring back and remain curved after the cut is
completed.
Jointing Short or Thin Work
When jointing short or thin pieces, use a push
block to eliminate all danger to the hands. Two
push blocks are shipped with your jointer. You can
also make your own easily from scrap material.
Two types are shown in Figure 23.

Direction of Grain
Avoid feeding work into the jointer against the
grain. This will result in chipped and splintered
edges. See Figure 24. Feed with the grain to
obtain a smooth surface, as shown in Figure 25.
