Adjusting/Replacing Knives
Before adjusting or replacing the knives, the tables
Must be parallel with each other (refer to check/
Adjusting Table Parallelism on Page 40).
in the adjustment procedure, both tables are low-
ered so that the knife setting gauge will fit on the
cutterhead, as shown in figure 55, and the knife
heights are set to just touch the middle pad of the
gauge.
the knife setting gauge makes it easy to ensure
that the knives project out of the cutterhead evenly.
after using the gauge to set the knives, you have
to re-adjust the outfeed table height to ensure that
it is even with the knives at their highest point of
rotation (refer to Setting Outfeed Table height
on Page 43 for detailed instructions).

the Model g0490 comes with set screw and

are used to adjust the height of the knives (see
