ADjUSTMENTS
1. Turn off and disconnect the machine from the power
source.
2. To give yourself unimpeded access to the cutter head
and knives, remove the blade guard and lower the
tables as far as they go.
3. Remove the fence to have access to the upper pulley
and turn it by hand to rotate the cutter head to access
one of the knives.
4. Loosen (but don't remove) all the gib bolts - start in the
center and alternate sides (If replacing an old or damaged
knife, loosen the bolts until the knife can be removed and
install a new sharpened knife). Then position the gauge
over the selected knife .
5. a) To use the adjustment springs to set the knife height:
Push the knife down with the gauge so that the edge
of the knife is touching the center reference pads on
the gauge . Hold the gauge down and tighten the bolts
to secure the knife in place. Repeat for the 2 other
knives.
b) To use the Jack Screws to set the knife height: Use an
Allen wrench to turn the screws to raise or lower the
knife as needed until the ideal position - both sets of
feet of the gauge sitting flush on the cutter head and
the knife barely touching the achieved. Repeat for
the 2 other knives.
6. Re-check the height setting on all the knives and re-set
if necessary.
7. Reset the tables and replace
the fence and blade guard.

Inspect Work Table Parallel to Cutterhead
The work table is set parallel to the cutterhead at the factory
and no further adjustment should be necessary. If your
machine is planing a taper, first check to see if the knives are
set properly in the cutterhead. Then check to see if the work
table is set parallel to the cutterhead. Proceed as follows:
1. Disconnect machine from power source.
2. Place the gauge block (Figure 18) on the work table directly
under the edge of a knife as shown. Make slight contact
by gently raising table.
3. Move the gauge block to the opposite end of the work
table. NOTE: Distance from the work table to edge of knife
should be the same at both ends.

Adjusting Work Table Parallel to Cutterhead
(Fine Adjustment)
The work table If the gap difference determined in
the previous section is greater than 0.004" and less than
0.016", perform the adjustment procedure as follows:
1. Determine which side of the table must be raised
to correct the gap.
2. Locate the two socket head cap screws in the table casting
for each of the columns (Figure 19). Loosen both sets of
screws for each column on the side you wish to adjust.
3. Push down or pull up the cutterhead assembly in the
desired direction. Hold the assembly in position and
retighten the cap screws.
4. Re-check the table-to-cutterhead parallelism again as
described in the previous section, then repeat
steps 1 through 3 until the deviation is less than 0.004".
