For most jointing operations, the surface of the
outfeed table must be level with the knife tips of
the cutterhead at their highest
revolution. The knife tips must project equally
from the cutterhead.
The outfeed table and cutterhead are adjusted
at the factory and should not require adjustment.
1. On the JJ-8CS Jointer, carefully number
each blade with a magic marker to make
them easier to differentiate.
2. Rotate the cutterhead by turning the
cutterhead pulley and determine the 12
