Knives 

 

Figure 7 

 

! WARNING  

The knives are extremely sharp. Use 
caution when handling. 

Installation of the Knives 

1.  To expose the cutterhead, move the fence 

all the way back. 

2. 

Back down both the infeed and outfeed 
tables to their lowest position.  Be sure to 
loosen the lock on the outfeed table 
before doing so.

 

3. 

Now turn the cutterhead by hand until one 
of the knives is exposed and accessible.  
Use gloves or a rag to prevent injury.

 

 
 
 

4. 

Using a 10mm wrench on the knife lock 
bolt, release the pressure on the knife by 
turning the bolt into the cutterhead as 
show in Figure 7.  To prevent injury, hold 
the wrench with one hand while tapping 
the top of the wrench with the other hand 
as shown.  Do this for all six bolts.

 

 
 

Figure 8 

5. 

Once all the bolts have been turned in, the 
knife should pop up from the spring 
pressure.  Remove the knife and 
immediately place the new knife in the slot 
to prevent loss of the springs.

 

Note

: It is not only important to set the height 

of the knife with respect to the cutterhead it is 
also important that the outside edge of the 
knives be aligned with the rabbeting ledge. 

 

6.  With the knife in the slot use a straight 

edge on the rabbeting ledge as shown in 
Figure 8 to push the knife into alignment 
with the edge. 

 
 
 
 

7.  Next use the supplied knife guage as 

shown to carefully push down on the knife 
until it is position as shown in Figure 9.  
Make sure the knife makes contact within 
the indent as shown by ‘A’ in Figure 9. 

 

8.  With the knife held firmly into place back 

the knife lock bolts out into the cutterhead 
in order to put pressure onto the knife.  
Work from the center bolts outward.  Do 
this in two steps.  First loosely, then firmly 
the second time. 

9.  Repeat the above for all knives. 

Note

:  The supplied guage sets the knives to 

the cutterhead however it is always best to set 
the knives to the outfeed table.  Many 
aftermarket devices are available to do this

.  

If 

using this method the knife should be no more

 

than 1/8” out of the cutterhead (not including 
the bevel)
