NOTE: Be certain to reassemble the flail screen with the curved side down as shown in figure 13. Hand Knobs FIGURE 13. SHARPENING OR REPLACING CHIPPER BLADES 1. Disconnect spark plug wire and move it away from spark plug. 2. Remove the flail screen as instructed in previous section. 3. Remove the chipper chute by removing three hex nuts and washers. A 1/2" wrench is required. See figure 13. NOTE: When reassembling, the cupped washer goes on the bottom of the chipper chute with the cupped side against the chute. 4. Rotate the impeller assembly by hand until you locate one of the chipper blades in the chipper chute opening. Remove the blade, using a 3/16" alien wrench on the outside of the blade and 1/2" wrench on the impeller assembly (inside the housing). See figure 14. 5. Remove the other blade in the same manner. FIGURE 14. Replace or sharpen blades. If sharpening, make certain to remove an equal amount from each blade. Reassemble in reverse order. Make certain blades are reassembled with the sharp edge facing the direction shown in figure 14 (sharp edge is assembled toward the slotted opening in the impeller assembly). SHARPENING OR REPLACING SHREDDING BLADE The shredding blade may be removed for sharpening or replacement as follows. 1. Disconnect spark plug wire and move it away from spark plug. 2. Lower the hopper assembly. Block up the housing. See figure 15. 3. Remove the six hex lock nuts and lock washers from the housing weld bolts using a 1/2" wrench. Separate the shredder into two halves. 4. Remove the back-up plate. NOTE: When reassembling, make certain the opening on the back-up plate is toward the bottom of the unit. The back-up plate may be reversed to provide a new cutting edge. 5. Loosen the two hand knobs and cupped washers which secure the chute deflector, and raise the chute deflector. 6. Keep the impeller assembly from turning by inserting a 1/2" or 3/4" diameter pipe through the flail screen, or remove the flail screen, and insert a piece of wood (2 x 4) into the chute opening. 7. Remove the two outside screws on the blade, using a 3/16“ alien wrench and a 1/2“ wrench. 8. Remove the blade by removing the center bolt, lock washer and flat washer. NOTE: Use caution when removing the blade to avoid contacting the weld bolts on the housing. 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 for balance by balancing it on a round shaft screwdriver or nail. Remove metal from the heavy side until it is balanced evenly. See figure 16. When reassembling the blade, tighten to between 550 and 650 inch pounds, or lacking torque wrench, tighten securely. FLAILS The flails, located inside the housing, may be reversed when they become dull. It is suggested that this procedure be performed by your nearest authorized dealer. CARBURETOR ADJUSTMENT A WARNING: If any adjustments are made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of heated surfaces and muffler. Minor carburetor adjustment may be required to compensate for differences in fuel, temperature, altitude or load. NOTE: A DIRTY AIR CLEANER WILL CAUSE ENGINE TO RUN ROUGH. BE CERTAIN AIR CLEANER IS CLEAN AND ATTACHED TO THE CARBURETOR BEFORE ADJUSTING CARBURETOR. Do not make unnecessary adjustments. Factory settings are satisfactory for most applications and conditions. If adjustment is needed, refer to the separate engine manual packed with your shredder. OFF-SEASON STORAGE The following steps should be taken to prepare your shredder for storage. 1. Clean and lubricate the shredder thoroughly as described in the lubrication instructions. 2. Refer to engine manual for correct engine storage instructions. 3. If storing in an unventilated or metal storage shed, coat metal parts with a light oil or silicone to prevent rust. 4. Store in a dry, clean area. Do not store next to corrosive materials, such as fertilizer. 9 I Models 645C AND 648C 10 Models 645C and 648C PARTS LIST FOR SHREDDERS REF. NO. PART NO.
