KNIFE ADJUSTMENTS
In order to do accurate work, the knives must be exactly
level with the outfeed table. To check and adjust,
proceed as follows:

POWER SOURCE.
1. Loosen infeed table lock lever and lower infeed table
as described under section “INFEED TABLE
ADJUSTMENTS”.
2. Remove cutterhead guard (C) Fig. 39.
3. Place a steel straight edge on the outfeed table,
extending over the cutterhead as shown in Fig. 40.
4. Carefully rotate the cutterhead by hand. The knives
should just touch the straight edge.
5. If the knife is high or low at either end, slightly turn
the four screws (D) Fig. 41, in the knife locking bar
clockwise to loosen using the wrench (E) supplied. Then
adjust the height of the knife by turning the knife raising
screws (F) Fig. 42, counterclockwise to lower and
clockwise to raise the knife.

HANDLING THE KNIVES, AS THE CUTTING EDGES
ARE VERY SHARP.
If the knife is to be lowered it will be necessary to
carefully push down on the knife with a scrap piece of
wood, after screws (F) have been turned. Tighten four
screws (D) Fig. 41, by turning them counterclockwise,
after adjustment is made.
6. Repeat these procedures for adjusting the remaining
two knives if necessary, and replace cutterhead guard
removed in STEP 2.
7. If the knives are set too low, the result will be as
shown in Fig. 43, and the finished surface will be curved.
8. If the knives are set too high, the work will be
gouged, curved, or bowed at the end of the cut, as
shown in Fig. 44.
9. As a final check, run a piece of work slowly over the
knives for 6 to 8 inches. The wood should rest firmly on
both tables as shown in Fig. 45, with no open spaces
under the finished cut.
