Sharpening Or Replacing The Shredder Blade
WARNING: The impeller’s chipper blades are sharp. Wear leather work gloves to protect your hands.
•Stop the engine and make certain that all moving parts have come to a complete stop.
•Disconnect the spark plug wire and ground against the engine.
•Lower the hopper assembly and block up the housing.
•Remove the six hex lock nuts and flat washers from the weld studs on the flail housing. Retain the hardware.
•Carefully separate the hopper assembly from the impeller assembly and remove the support plate.
NOTE: When reassembling the support plate, make certain the embossed tab faces inward towards the impeller.
•Remove the two wing knobs and cupped washers that secure the discharge chute and raise the chute.
•Insert a 1/2” or 3/4” diameter pipe through the flail screen into the impeller to keep it from turning or remove the flail screen and insert a piece of wood into the chute opening.
•Remove the two internal hex screws which secure the shredder blade to the impeller. See Figure 11.

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.
•Remove the hex bolt, lock washer and flat washer to completely free the shredder blade.
NOTE: Use caution when removing the blade to avoid contacting the weld studs on the 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.
IMPORTANT: When reassembling the blade, tighten center bolt to between 550 and 700
Storing Your Chipper Shredder
•Clean the equipment thoroughly.
•Wipe equipment with an oiled rag to prevent rust.
•Refer to engine manual for correct engine storage instructions.
•Store unit in a clean, dry area. Do not store next to corrosive materials such as fertilizer.
