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:

DISCONNECT MACHINE FROM

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. 23.

3. Place a steel straight edge on the outfeed table,

extending over the cutterhead as shown in Fig. 24.

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. 25, 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. 26, counterclockwise to

lower and clockwise to raise the knife.

CARE MUST BE TAKEN WHEN

HANDLING THE KNIVES, AS THE CUTTING EDGES

ARE VERY SHARP. WEAR PROTECTIVE GLOVES

WHEN HANDLING THE KNIVES.

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 counterclockwise to achieve

desired depth. Tighten four screws (D) Fig. 25, 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. 27, 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. 28.

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. 29, with no open

spaces under the finished cut.
