ROTATING OR REPLACING KNIFE INSERTS

This machine has a helical-style cutterhead with six 

rows of carbide knife inserts. Each of the 12 inserts 

on the cutterhead are indexed and have two sharp-

ened sides. If the knives become dull, or one be-

comes nicked, simply loosen the retaining screws with 

the supplied star head screwdriver, lift up and rotate 

the inserts to a new sharpened edge. No setting is 

required, as the cutterhead has been machined to au-

tomatically index and set the inserts in proper position 

for use. When both edges of an insert are dull, the 

insert can be easily removed and a new carbide insert 

placed in the location.  To rotate or remove an insert:

1.  Unplug power cable and make sure that the switch 

is in the off position, with the safety tab removed.

2. To keep the cutterhead from rotating while working 

on the knives, insert the supplied hex wrench into the 

end of the cutterhead shaft that faces the front of the 

machine, under the guard’s front tab. The cutterhead 

can then be safely rotated and positioned for chang-

ing the insert cutters. FIG. 22.

3.  Remove the Star Screw, that holds the Insert in the 

cutterhead, and also remove the Insert Knife. FIG. 23.

4.  While the insert is removed, clean any resin build-

up or trapped dust from the surfaces of the cutterhead 

with a suitable solvent. A tooth brush works well for 

safe cleaning around the sharp inserts. Any accumu-

lated dust can affect the seating of the insert in

Wear gloves when changing knife 

inserts to avoid the risk of personal injury by cuts that 

may result from touching the sharp edges! 

THE MACHINE MUST NOT BE 

PLUGGED IN AND THE POWER SWITCH MUST BE IN 
THE OFF POSITION UNTIL ALL ADJUSTMENTS ARE 
COMPLETE.

the cutterhead, causing it to rise slightly and make 

a small, but noticeable mark on your workpiece next 

time you mill stock. NOTE; these marks/lines will 

easily sand off in your finishing process.

5.  Rotate the insert so that a new sharpened edge 

is in position. The inserts have a indication mark on 

their top surface corner, so that you can reference the 

positioning of the insert’s dulled or sharpened edges. 

FIG. 23.

5.  Tighten the insert’s set screw to lock the insert 

back in position. DO NOT overtighten the screw or 

damage to the insert may result. Torque the screw in 

place to 48-50 in/lbs.

6.  Plug in the power cable and return the safety tab 

into the switch when you are ready to resume jointing

on the machine.
