Max-Z-Lube to the mating surfaces of the blades near the pivot
as shown in Figure #40. Pick up the fixed blade and align the flat on the pivot nut with "D" shaped
hole on the blade. Push the pivot nut into the hole and hold it in place with your finger. Place the
movable blade over the pivot nut, and against the fixed blade. Place the locknut, with the plastic
washer, onto the blade and screw it into the threads of the pivot bushing (clockwise).
The lock nut should produce some resistance to turning. Use a 5/8 inch wrench to screw the
locknut in until it just contacts the blade. Install the blade screw, then perform the blade nut
adjustment (see Section 9.3.4).
