REPLACING KNIVES
The knives supplied with your planer are double edged and reversible so that you can turn the knives end-for-end when
one edge becomes dull or chipped. To change the knives:
Disconnect machine from power source!
1. Remove the two top covers (C) Fig. 28.
2. Raise the head assembly (B) to 4" (102 mm) on the
"Scale and Pointer".
3. Remove the two screws (A) Fig. 28. Pull the
cutterhead guard (B) straight out.
The knives are sharp. Be careful when
removing, handling, or installing knives.
4. Pull the guard down (G) Fig. 29 to gain access to the
hex hole in the end of the cutterhead.
5. Insert the supplied wrench into the hex hole (A)
Fig. 29. Rotate the cutterhead until the cutterhead
lock engages.
6. Use the wrench (E) Fig. 30 to loosen the seven
screws (F) enough to allow the locking bar (D) to
separate from the knife.
7. Place the magnetized knife transfer tool (G) Fig. 31
under the center of the knife. Lift the knife transfer
tool until the knife (H) separates from the pins.
Remove the knife.
