The only wear item in the feed area is the knife blade (see figure 17-2). If the wire has a burr on it after
cutting, or, if a groove has worn into the cutting edge of the knife, it is time to rotate the blade. The knife
blade has four cutting edges on it. To switch to a new cutting edge, the following steps are
recommended:
A. Disconnect air and electrical power from the machine.
B. Remove feed cover.
C. Using a 5/32” hex key, loosen and remove the two screws, which secure the cutting block.
D. Loosen the jam nut and remove the pivot screw.
E. Flip the blade over to a new cutting edge.
F. Apply grease to the pivot screw and the mating surfaces of the cutting block and the knife blade.
G. Install the knife blade by tightening the pivot screw enough so the blade pivots freely with zero
clearance to the cutting block.
H. Tighten the jam nut to secure the pivot screw.
I. Apply grease to the pin for the upper pivot joint and attach the knife blade
USE CAUTION! KNIFE BLADE IS VERY SHARP!!
J. Mount the cutting block.
