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. If adjustment is needed, refer to the separate engine manual packed with your shredder. Hi^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. MAINTENANCE Ac WARNING \ Disconnect spark plug wire and ground it against the engine before performing any repairs or maintenance. ENGINE Refer to the separate engine manual packed with your unit for all engine maintenance procedures. Read instructions carefully. AIR CLEANER The air cleaner prevents damaging dirt, dust, etc., from entering the carburetor and being forced into the engine and is important to engine life and performance. Never run your engine without air cleaner completely assembled. To service air cleaner; refer to the separate engine manual packed with your unit. LUBRICATION Wheels - The wheels require no lubrication. Flails and Fingers - If the unit is disassembled for any reason, lubricate the flails and fingers with a light oil (engine oil may be used). 8 II Bill CUTTING BLADE The cutting blade may be removed for grinding or replacement as follows. 1. Lower the upper guide extension. 2. Block up the housing. See figure 15. 3. Remove the four elastic lock nuts from the back of the housing using a 1/2” wrench. Refer to figure 13. Separate the shredder into two halves. 4. Remove the back-up plate. See figure 15. 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. Hold the blade retainer on the impeller assembly with an adjustable wrench to keep the blade from turning as shown in figure 15. 6. 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 protruding from the housing. At WARNING I The blade is reversible and can be assembled to the crankshaft with either side showing. 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 round shaft screwdriver or nail. Remove metal from the heavy side until it balanced evenly. See figure 16. When reassembling the blade, tighten to between 375 and 450 inch pounds, or lacking torque wrench, tighten securely. FLAILS AND FINGERS The flails and fingers may be reversed when they become dull. It is suggested that this procedure be performed by your nearest authorized service dealer. OFF-SEASON STORAGE If the shredder is to be inoperative for a period longer than 30 days, the following precautions are recommended. 1. Working outdoors, drain all fuel from the fuel tank. Run the engine until it stops from lack of fuel. AC WARNING I DO NOT DRAIN FUEL WHILE SMOKING, OR IF NEAR AN OPEN FIRE. 2. Drain all the oil from the crankcase (this should be done after the engine has been operated and is still warm) and refill crankcase with fresh oil. 3. Protect the inside of the engine for storage 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. 4. Clean the engine and the entire unit thoroughly. NOTE When storing any type of power equipment in an unventilated or metal storage shed, care should be taken to rustproof the equipment. Using a light oil or silicone, coat the equipment, especially all moving parts. 5. Store in a clean, dry area. g Model 650 10 Model 650 PARTS LIST FOR MODEL 650 SHREDDER Ref.
