Knife-Setting Jig Method
The infeed table is lowered to fit the jig on the
cutterhead, as shown, and the knife heights
are set to just touch the middle pad of the jig.
The knife-setting jig included with the jointer is
designed to set all the knives evenly and at the
correct height in the cutterhead.

height.
5. Closely examine how jig touches cutterhead
and knife. Knife is set correctly when, on
each side of cutterhead, both legs of jig sit
firmly on cutterhead body and middle pad of
jig just touches top edge of knife.
— If jig does not sit as described, then that
knife must be reset. Repeat this inspec-
tion with other knives before resetting.
