6.Remove the blade by removing the internal hex screws, lock washers, and hex nuts which secure it to the impeller. Retain the hardware. See Figure 5-3.

NOTE: Use a 3/16” hex key (Allen) wrench on the outside of the shredder blade and a 1/2” box (or socket) wrench on the inside of the shredder blade. Hold the Allen wrench stationary and rotate the box (or socket) wrench to loosen the nut. Use caution when removing the blade to avoid contacting the weld studs on housing.

IMPORTANT: When sharpening the blade, follow the original angle of grind as a guide. It is extremely important that each cutting edge receives an equal amount of grinding to prevent an unbalanced blade. An unbalanced blade will cause excessive vibration when rotating at high speeds and may cause damage to the unit. The blade can be tested by balancing it on a screwdriver or nail. Remove metal from the heavy side until it is balanced evenly.
