5. Carefully inspect how the gauge touches the
cutterhead and the knife.
— If both outside legs of the gauge sit firmly
on the cutterhead and the middle pad just
touches the knife, then that knife is set
correctly. (Repeat this inspection with the
other knives.)

Setting/Replacing
Knives
Setting the knives correctly is crucial to the proper
operation of the jointer and is very important in
keeping the knives sharp. If one knife is higher
than the others, it will do the majority of the work,
and thus, dull much faster than the others.
The knife gauge included with the jointer is
designed to set the knives at 0.063" (
1
/16"), which
is the correct distance all the knives should pro
-
trude above the cutterhead.
The Model G0656 comes with jack screws for
cutterhead adjustments (see
Figure 52).
