HOW TO SET A KNIFE
Loosen (clockwise) all five locking screws, two of which
are shown at (K) Fig. 45. Use the supplied wrench to turn
the hex screw (L) Fig. 45 counterclockwise to lower or
clockwise to raise the knife on each end of the cutterhead
until the cutting edge of knife (H) Fig. 44 touches the bottom
of the gauge (J) Fig. 44. Tighten the knife locking bar (N) Fig.
45 by lightly backing out the five locking screws (K) Fig. 45
against the knife slot.
IMPORTANT: Tighten the knife in the slot only enough
to hold it in position.
After all three knives are set, tighten the five locking screws (K) Fig. 45 against the slot. Start with the end screws first, then
the center screws until the knife is secure. Tighten the other knives in the same manner.
HOW TO CLEAN AND CHECK THE KNIVES
Wear gloves when you remove the knives for sharpening or replacement. The knives are very
sharp.
Disconnect the machine from the power source.
A. Remove the knife (H) Fig. 46, locking bar (N), and
locking screws (K) from the cutterhead. Repeat
this process for the other knives, locking bars,
and locking screws.
b. Thoroughly clean the knives, knife slots, locking
bars, and locking screws. If the threads of the
screws appear worn or stripped, or if the heads
are becoming rounded, replace them.
C. Insert the locking bars, knives, and screws in all
three slots in the cutterhead. loosen the locking
screws, two of which are shown at (K) Fig. 45
enough to hold all three knives in the cutterhead.
d. Adjust all three knives as explained under STEP 4.
IMPORTANT: After the knives have been ad just ed, re place the chip deflector that was removed in STEP 3 and the top
cover that was removed in STEP 1 (under How to Check, Adjust and Replace Knives.) Pivot the motor assembly
back to its original place.
HOW TO CONSTRUCT THE GAUGE BLOCK
Use a gauge block to check and adjust the height of the
chipbreaker and the infeed and outfeed roll. Adjust the
cutterhead parallel to the table. Construct a gauge block
from hard wood using the dimensions in Fig. 47.
