ROTATING OR REPLACING KNIFE INSERTS
This machine has a cutterhead with 6 rows of High Speed Steel knife inserts. Each of the 26 inserts on the
cutterhead are indexed and have two sharpened sides. If the knives become dull, or one becomes nicked,
simply loosen the retaining screws with the supplied star head screwdriver, lift up and rotate the inserts 90° to
a new sharpened edge. No setting is required, as the cutterhead has been machined to automatically index
and set the inserts in proper position for use. When both sides of an insert are dull, the insert can be easily
removed and a new knife insert placed in the location.
To rotate or remove an knife insert:
1. Unplug power cable, put the switch to OFF and remove the safety key.
2. Lower the upper frame motor housing to the lowest position near the planer bed by turning the handwheel.
3. From the back of the planer, remove the two Dust Hood Knobs and take off Dust Hood. (A-FIG. 10.)
4. Remove any sawdust from the head of the Star screw then remove the screw and cutter insert.
5. Safely rotate the cutterhead by inserting the supplied 4mm hex wrench into the side of the planer
(B-FIG. 10.). Engage the end of the cutterhead with the wrench and rotate to the next row.
6. While the insert is removed, clean any resin buildup or trapped dust from the insert and surfaces of the
cutterhead with a suitable solvent. A tooth brush works well for safe cleaning around the sharp inserts. Using
compressed air is also useful. Be sure to wear safety glasses if compressed air is used.
NOTE:
Any accumulated dust or resin buildup can affect the seating of the insert in the cutterhead, raise it, and
can make noticeable marks on your workpieces the next time you plane.
7.
Lubricate the Star screw threads with a light machine oil, wipe the excess oil off the threads.
8. Install a new insert, or rotate the old 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. When rotating a cutter insert, it will seat itself back against the positioning bar during tighten-
ing. Install the Star screw and torque it down to 48-50 inch / pounds. Inserts have 2 sharp edges, 2 flat edges.
See FIG. 11, page 15.
9. Once all insert changes have been made, put the planer parts back together by reversing steps 2-4 above.
10. Plug in the power cord and safety key when you are ready to resume planing.
