Knives 

!



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.

 

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)
