Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel stabilizer. • Drain all the oil from the crankcase (this should be done after the engine has been operated and is still warm) and refill the crankcase with fresh oil. • If you have drained the fuel tank, protect the inside of the engine as follows. Remove spark plug, pour approximately 1/2 ounce (approximately one tablespoon) of engine oil into cylinder and crank slowly to distribute oil. Replace spark plug. OTHER • Do not store gasoline from one season to another. • Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems. • Store unit in a clean, dry area. Do not store next to corrosive materials, such as fertilizer. NOTE: If storing in an unventilated or metal storage shed, be certain to rustproof the equipment by coating with a light oil or silicone. SERVICE & ADJUSTMENT A WARNING: ALWAYS STOP ENGINE AND DISCONNECT SPARK PLUG WIRE AND MOVE IT AWAY FROM SPARK PLUG BEFORE PERFORMING ANY ADJUSTMENTS OR REPAIRS. REMOVING THE FLAIL SCREEN If the discharge area becomes clogged, remove the flail screen and clean area as follows. • Stop the engine, make certain the chipper-shredder has come to a complete stop and disconnect spark plug wire from the spark plug before unclogging the chute. • Loosen the two hand knobs on each side of the chute deflector. Lift the chute deflector up, and tie it out of the way. • Remove two hairpin clips from the clevis pins which extend through the housing. Remove the clevis pins. Lift the flail screen from inside the housing. See figure 18. • Clean the screen by scraping or washing with water. Reinstall the screen. NOTE: Be certain to reassemble the flail screen with the curved side down as shown in figure 18. 14 Chute Deflector Hand Knobs FIGURE 18. SHARPENING OR REPLACING THE BLADES CHIPPER BLADES • Disconnect spark plug wire and move it away from spark plug. • Remove the flail screen as instructed in previous section. • Remove the chipper chute by removing three hex nuts and washers. A 1/2" wrench is required. See figure 18. NOTE: When reassembling, the cupped washer goes on the bottom of the chipper chute with the cupped side against the chute. • 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 19. • Remove the other blade in the same manner. 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 18 (sharp edge is assembled toward the slotted opening in the impeller assembly). Torque bolts and nuts to 250-350 inch pounds. SHREDDING BLADE The shredding blade may be removed for sharpening or replacement as follows. • Disconnect spark plug wire and move it away from spark plug. • Lower the hopper assembly. Block up the housing. See figure 20. • Remove the six hex lock nuts and lock washers from the housing weld bolts using a 1/2" wrench. Separate the chipper-shredder into two halves. • 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. Allen Screws FIGURE 20. Torque Wrench FIGURE 19. Loosen the two hand knobs and cupped washers which secure the chute deflector, and raise the chute deflector. 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 (2 x 4) into the chute opening. Remove the two outside screws on the blade, using a 3/16" alien wrench and a 1/2" wrench. Remove the blade by removing the center bolt, lock washer and flat washer. 15 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 21. • When reassembling the blade, tighten to between 550 and 650 inch pounds, or lacking torque wrench, tighten securely.
