Simplicity 14E manual Removing Chipper Knife Through Front Opening

4.Using a 1/4” hex wrench, loosen and remove the two socket head cap screws holding the chipper knife in place (access the screw heads from the rear of the unit), and remove the chipper knife.

CAUTION

The chipper blades have sharp edges. Wear leather work gloves and remove the blades care- fully.

5.See Figure 32. Remove both knives through the opening in the front of the chipper/shredder, and sharpen equally or replace both blades to ensure proper balancing and correct chipping action.

NOTE: Slow-speed water-cooled grinding is suggested to help maintain blade temper and a long-lasting sharp edge. Rapid grinding and heating of blades will soften the edges, making repeated sharpening necessary.

Chipper knives require a 30° bevel on the cutting edge (as shown in Figure 33) for efficient chipping action.

Contact your local dealer or blade sharpening service if you prefer not to sharpen the blades yourself.

6.Clean the chipper knife mounting areas before rein- stalling the blades to ensure a flat mounting surface.

7.Install the new chipper knives using the two socket head cap screws, and two new lockwashers, torque to 18-20 ft. lbs. Never reinstall chipper knives with used lockwashers, as used lockwashers may not hold the knives adequately.
