Thickness Stop
Calibration
the thickness stop is set at the factory and should
not require adjustment. however, with extended
use, it is possible that the thickness stop may
come out of adjustment. if you notice that use of
the thickness stop is not producing results to your
standards, you may need to adjust it.

5. place the 1 1 ⁄

" thick board on the table and
lower the cutterhead until the knife just
touches the board when the knife is at its low-
est position (turn the belt pulley to rotate the
cutterhead as needed).
6. loosen the lock nut and adjust the stop bolt
as needed until it just touches the thickness
stop, then re-tighten the lock nut.
7. reassemble the machine, then check to see
if the thickness stop is producing the desired
results. repeat as necessary.
4. loosen the lock nuts, then turn each adjust-
ment bolt so that it just touches the cam
when the lock lever is approximately halfway
through its travel, then tighten the lock nuts.
Note: It is important that all four adjustment
bolts are set equally. Failure to do this could
cause the cutterhead to move during use,
resulting in inconsistent planing.
4. locate the thickness stop bolt and lock nut.
