Use push blocks to rabbet cut whenever
possible. The rabbeting capacity is 3/4”.
1. Disconnect machine from power source.
2. Set fence for desired width of rabbet.
3. Check width of the rabbet by measuring the
distance from the end of a knife in the
cutterhead to the fence.
4. Reconnect power. Lower the infeed table
1/32” at a time and make successive cuts
until the desired depth of rabbet has been
obtained. See Figure 28. 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, and
additional ones (stock no. 6285917) can be
purchased from your distributor or by calling 1-
800-274-6848. You can also make your own
easily from scrap material. Three types of
commonly used push blocks are represented in
Figure 29.
Direction of Grain
Avoid feeding work into the jointer against the
grain. This will result in chipped and splintered
edges. See Figure 30. Feed with the grain to
obtain a smooth surface, as shown in Figure 31.
Beveling
To cut a bevel, lock the fence at the required
angle and run the workpiece across the knives
while keeping it firmly against the fence and
tables. Several passes may be necessary to
achieve the desired result.
While the fence can be tilted in or out for bevel
cutting, it is recommended for safety reasons
that the fence be tilted in toward the operator, if
possible, making a cradled cut.
