Loosen the two hand knobs and cupped washers which secure the chute deflector, and raise the chute deflector. 6. Insert a 1/2" or 3/4" diameter pipe through the flail screen into the impeller assembly to keep it from turning, or remove the flail screen, and insert a piece of wood (2 x 4) into the chute opening. 7. Models 242A645 and 242A648 only: Remove the two outside screws on the blade, using a 3/16" alien wrench and a 1/2" wrench. 8. All Units: 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 17. Nail / \ \ Blade FIGURE 17-Model 242A645 &242A648 Shown 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 Models 645 and 648 NOTE This instruction manual covers various models, and all specifications shown do not necessarily apply to your model.
