Determining Correct Table Height

The Outfeed Table Height Adjustment section tells
you how to set the correct table height with respect
to the cutterhead knives or knife inserts. This
section explains how to determine if the outfeed
table needs adjustment based upon the cuts being
produced.
When you receive the jointer, the knives have
been pre-set at the factory. However, the height
and parallelism of the knives with the outfeed table
should be checked and any needed adjustments
made before putting the jointer into operation.
The outfeed table and cutterhead knives (Model
54A only) are correctly adjusted when all three
blades are parallel to the outfeed table and all
three blades are set at the same height in the
cutterhead.
Outfeed table too high – If the outfeed table is too
high, a curved finished surface results (Figure 29).
Outfeed table too low – If the outfeed table is too
low, the work will have a gouge, or snipe, at the
end of the cut (Figure 30).
Outfeed table at correct setting – Figure 31
illustrates the correct setting of outfeed table level
with the knives. The workpiece will rest firmly on
both tables with no open space under the finished
cut.
