OPERATION  Align the holes on the new bottom blade with the spindles in the bottom half of the cutter housing. NOTE: The holes are offset to allow the blade to install correctly in only one position. If the blade does not fit properly, turn it over and try inserting again.  Place the new top blade onto the spindle and align the notched end with the cam.  Reinstall the washer onto the spindle.  Reinstall the top cutter housing by aligning the spindle and the gap adjustment screw and pressing onto the bottom cutter housing until completely seated.  Insert the lock nuts into the holes as shown; cover them with your hand and turn the tool over.  Insert the bolts through the housing and into the lock nuts. Using the hex wrench, tighten bolts securely. Once the new blades are installed, refer to Adjusting the Cutting Blades earlier in this manual to properly set the gap adjustment for the material to be cut.
