STORAGE Prepare your chipper-shredder for storage at the end of the season or if the unit will not be used for 30 days or more. WARNING: NEVER STORE MACHINE WITH FUEL IN THE FUEL TANK INSIDE OF BUILDING WHERE FUMES MAY REACH AN OPEN FLAME OR SPARK, OR WHERE IGNITION SOURCES ARE PRESENT SUCH AS HOT WATER AND SPACE HEATERS, FURNACES, CLOTHES DRYERS, STOVES, ELECTRIC MOTORS, ETC. NOTE: A yearly check-up by your local Sears Service Center is a good way to make certain your chipper- shredder will provide maximum performance for the next season. CHIPPER-SHREDDER ⢠Clean the chipper-shredder thoroughly. ⢠Wipe unit with an oiled rag to prevent rust (use a light oil or silicone). ENGINE IMPORTANT: IT IS IMPORTANT TO PREVENT GUM DEPOSITS FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH AS CARBURETOR, FUEL FILTER, FUEL HOSE, OR TANK DURING STORAGE. ALSO, EXPERIENCE INDICATES THAT ALCOHOL BLENDED FUELS (CALLED GASOHOL OR USING ETHANOL OR METHANOL) CAN ATTRACT MOISTURE WHICH LEADS TO SEPARA- TION AND FORMATION OF ACIDS DURING STOR- AGE. ACIDIC GAS CAN DAMAGE THE FUEL SYS- TEM OF AN ENGINE WHILE IN STORAGE. ⢠Drain the fuel tank. ⢠Start the engine and let it run until the fuel lines and carburetor are empty. ⢠Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. ⢠Use fresh fuel next season. NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or stor- age 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 carbure- tor 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 table- spoon) 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 WARNING: ALWAYS STOP ENGINE AND DISCONNECT SPARK PLUG WIRE AND MOVE IT AWAY FROM SPARK PLUG BEFORE PERFORMING ANY ADJUST- MENTS 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 19. ⢠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 19. 13

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 _revious section. ⢠Remove the chipper chute by removing three hex nuts and washers. A 1/2" wrench is requi_'ed. See figure 19. 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 Lntil you locate one of the chipper blades in the chipper chute opening. Remove the blade, using a 3/16" allen wrench on the outside of the blade ._nd 1/2" wrench on the impeller assembly (inside the hous- ing). See figure 20. ⢠Remove the other blade in the same manm;r. Replace or sharpen blades. If sharpening, make cer- tain 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 19 (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 21. ⢠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 open- ing 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 Pipe Sharp Edg_ FIGURE 21. Torque Wrench 14 ⢠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" allen wrench and a 1/2" wrench. ⢠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 unbal- anced 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 22. Nail / ° Blade ! \ FIGURE 22. ⢠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 Sears Service Department. THROTTLE ADJUSTMENT To adjust throttle control lever, loosen or tighten wing nut until throttle control lever moves with some resis- tance and still remains in desired position when engine is running. See figure 23. Throttle Control. Lever Wing Nut FIGURE 23. CARBURETOR ADJUSTMENT WARNING: IF ANY ADJUSTMENTS ARE _IL MADE TO THE ENGINE WHILE THE ENGINE IS RUNNING (E.G. CARBURE- TOR), KEEP CLEAR OF ALL MOVING PARTS. BE CAREFUL OF HEATED SUR- FACES AND MUFFLER. Minor carburetor adjustment may be required to com- pensate 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 CARBURE- TOR. DO NOT MAKE UNNECESSARY ADJUST- MENTS. FACTORY SETTINGS ARE SATISFACTO- RY FOR MOST APPLICATIONS AND CONDITIONS. Never attempt to change maximum engine speed. It is pre-set at the factory and should be changed only by a qualified service technician who has the necessary equipment. The carburetor may need re-adjusting if engine lacks power or does not idle properly. If adjustments are needed, proceed as follows. ⢠Close idle mixture valve (see figure 24) clockwise ( f'_ ) finger tight only. Forcing may cause damage. Then open 1-1/2 turns counterclockwise ( ,,_ ). ⢠Start engine and allow to warm for five minutes. ⢠Move throttle control lever to IDLE position. ⢠Rotate throttle counterclockwise (,,_) and hold against idle speed adjusting screw. Turn idle speed adjusting screw until engine is running at 1750 RPM. ⢠Turn idle mixture valve clockwise (¢-_) (lean mix- ture) until engine JUST starts to slow. Then turn it counterclockwise (,,--,) (rich mixture) until engine starts to run unevenly. Set at midpoint between rich and lean mixture. ⢠Recheck idle RPM and readjust if necessary. ⢠Move throttle control lever to FAST position. Engine should accelerate without hesitation or sputtering. If it does not, carburetor should be read- justed, usually to a slightly richer mixture. Speed Screw Throttle Idle Mixture Valve FIGURE 24. ENGINE SPEED Your engine speed has been factory set. Do not attempt to increase engine speed or it may result in personal injury. If you believe the engine is running too fast or too slow, take your chipper-shredder to the nearest SEARS Service Center for repair and adjust- ment. TIRES Recommended operating tire pressure is 24 p.s.i. (sidewall of tire may give tire manufacturer's recom- mended pressure). Equal tires pressure should be maintained on both rires. When installing a tire to the rim, be certain rim is clean and free of rust. Lubricate both the tire and rim generously. 15

IMPORTANT: There is a flail screen located inside the housing in the discharge area. If the flail screen becomes clogged, remove and clean as instructed in the Service and Adjustments section. For best per- formance, it is important to keep the shredding blade and the chipper blades sharp. If the composition of the material being discharged changes (becomes stringy, etc.) or if the rate at which the material is dis- charged slows down considerably, it is likely that the shredding blade and/or chipper blades are dull and need to be replaced. Refer to Service and Adjustments section. 5W30 SAE 30 NOTE: Although multi-viscosity oils (5W30, 10W30, etc.) improve starting in cold weather, these multi- viscosity oils will result in increased oil consumption when used above 32°F. Check your oil level more fre- quently to avoid possible engine damage from running low on oil. ⢠Fill engine with oil as follows. Remove oil fill dip- stick. See figure 12. With chipper-shredder level, use a funnel to fill engine with oil to FULL mark on dipstick. Capacity is approximately 1-1/4 pints (20 oz.). Be careful not to overfill. Tilt chipper-shredder toward the left (from behind the hopper), then re- level. Check oil level. Refill to FULL mark on dip- stick if necessary. Replace dipstick and tighten. Oil Fill Dipstick Oil Drain FIGURE 12. GAS ⢠Remove fuel cap and fill fuel tank with about 1 gal- lon of clean, fresh, lead-free grade automotive gasoline. DO NOT use Ethyl or high octane gaso- line. Be certain container is clean and free from rust or foreign particles. Never use gasoline that may be stale from long periods of storage in the container. Replace fuel cap. WARNING: DO NOT FILL CLOSER THAN 1/2 INCH OF TOP OF FUEL TANK TO PREVENT SPILLS AND TO ALLOW FOR FUEL EXPANSION. IF GASOLINE IS ACCIDENTLY SPILLED, MOVE CHIPPER- SHREDDER AWAY FROM AREA OF SPILL. AVOID CREATING ANY SOURCE OF IGNITION UNTIL GASOLINE VAPORS HAVE DISAPPEARED. Check the fuel level periodically to avoid running out of gasoline while operating the chipper-shredder. If
the unit runs out of gas as it is shredding or chipping, it may be necessary to unclog the unit before it can be restarted. Refer to "Removing the Flail Sc'een" in SERVICE AND ADJUSTMENT section.

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 _ nd per- formance. Never run your engine without air cleaner com- pletely assembled. To Service Air Cleaner: Service pre-cleaner after every 25 hours of use, or at least once a season. Service cartridge every 130 hours of use, or at least once a season. Service pn;-cleaner and cartridge more often under dusty conditions. ⢠Loosen air cleaner cover screws. Remo-e cover and air cleaner assembly from base. See fi jure 15. ⢠Remove air cleaner assembly from inside cover and disassemble. ⢠To service foam pre-cleaner: Remove pre.cleaner. Wash in liquid detergent and water. Squee_,e dry in a clean cloth. Saturate in engine oil. Squeeze in a clean, absorbent cloth to remove all excess oil. If pre-cleaner is very dirty, replace it. ⢠To service cartridge: Clean by tapping gently on a flat surface. If very dirty, replace. Do not oil cartridge. NOTE: Do not use petroleum solvents (e.g. k_;rosene) or pressurized air to clean cartridge. They wll cause cartridge to deteriorate. ⢠Reassemble retainer on pre-cleaner and _:artridge (screen side of pre-cleaner toward c_lrtridge pleats). Place assembly into cover. ⢠Insert tabs on cover into slots in base and tighten cover screws securely. Retainer Pre-Cleaner Cartrid( Cover Bas e Slot FIGURE 16. CLEAN ENGINE Clean engine periodically. Remove dirt and debris with a cloth or brush. Cleaning with a forceful spray of water is not recommended as water could contami- nate the fuel system. Yearly or every 25 hours, whichever occurs first, remove the blower housing and clean the areas shown in figure 17 to avoid overspeeding, overheating and engine damage. Clean more often if necessary. ,_ WARNING: PERIODICALLY CLEAN MUF- FLER AREA TO REMOVE ALL GRASS, DIRT AND COMBUSTIBLE DEBRIS. Clean Out Chaff and Dirt FIGURE 17. SPARK PLUG The spark plug should be cleaned and the gap reset to .030" at least once a season or every 50 hours of operation. See figure 18. Spark plug replacement is recommended at the start of each season. Refer to engine parts list for correct spark plug type. NOTE: Do not sandblast spark plug. Spark plug should be cleaned by scraping or wire brushing and washing with a commercial solvent. .030" Feeler Gauge FIGURE 15. Screws FUEL FILTER Your engine is equipped with a replaceable in, line fuel filter. Replace the fuel filter every season. See figure 16. Refer to engine parts list for correct repl_Lcement filter. FIGURE 18. Spark Plug MUFFLER Do not operate the chipper-shredder without a muffler or tamper with the exhaust system. Damaged mufflers or spark arresters could create a fire hazard. Inspect periodically, and replace if necessary. If your engine is equipped with a spark arrester screen assembly, remove every 50 hours for cleaning and inspection. Replace if damaged. 12
STORAGE Prepare your chipper-shredder for storage at the end of the season or if the unit will not be used for 30 days or more. WARNING: NEVER STORE MACHINE WITH FUEL IN THE FUEL TANK INSIDE OF BUILDING WHERE FUMES MAY REACH AN OPEN FLAME OR SPARK, OR WHERE IGNITION SOURCES ARE PRESENT SUCH AS HOT WATER AND SPACE HEATERS, FURNACES, CLOTHES DRYERS, STOVES, ELECTRIC MOTORS, ETC. NOTE: A yearly check-up by your local Sears Service Center is a good way to make certain your chipper- shredder will provide maximum performance for the next season. CHIPPER-SHREDDER ⢠Clean the chipper-shredder thoroughly. ⢠Wipe unit with an oiled rag to prevent rust (use a light oil or silicone). ENGINE IMPORTANT: IT IS IMPORTANT TO PREVENT GUM DEPOSITS FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH AS CARBURETOR, FUEL FILTER, FUEL HOSE, OR TANK DURING STORAGE. ALSO, EXPERIENCE INDICATES THAT ALCOHOL BLENDED FUELS (CALLED GASOHOL OR USING ETHANOL OR METHANOL) CAN ATTRACT MOISTURE WHICH LEADS TO SEPARA- TION AND FORMATION OF ACIDS DURING STOR- AGE. ACIDIC GAS CAN DAMAGE THE FUEL SYS- TEM OF AN ENGINE WHILE IN STORAGE. ⢠Drain the fuel tank. ⢠Start the engine and let it run until the fuel lines and carburetor are empty. ⢠Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. ⢠Use fresh fuel next season. NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or stor- age 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 carbure- tor 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 table- spoon) 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 WARNING: ALWAYS STOP ENGINE AND DISCONNECT SPARK PLUG WIRE AND MOVE IT AWAY FROM SPARK PLUG BEFORE PERFORMING ANY ADJUST- MENTS 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 19. ⢠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 19. 13

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 _revious section. ⢠Remove the chipper chute by removing three hex nuts and washers. A 1/2" wrench is requi_'ed. See figure 19. 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 Lntil you locate one of the chipper blades in the chipper chute opening. Remove the blade, using a 3/16" allen wrench on the outside of the blade ._nd 1/2" wrench on the impeller assembly (inside the hous- ing). See figure 20. ⢠Remove the other blade in the same manm;r. Replace or sharpen blades. If sharpening, make cer- tain 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 19 (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 21. ⢠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 open- ing 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 Pipe Sharp Edg_ FIGURE 21. Torque Wrench 14 ⢠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" allen wrench and a 1/2" wrench. ⢠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 unbal- anced 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 22. Nail / ° Blade ! \ FIGURE 22. ⢠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 Sears Service Department. THROTTLE ADJUSTMENT To adjust throttle control lever, loosen or tighten wing nut until throttle control lever moves with some resis- tance and still remains in desired position when engine is running. See figure 23. Throttle Control. Lever Wing Nut FIGURE 23. CARBURETOR ADJUSTMENT WARNING: IF ANY ADJUSTMENTS ARE _IL MADE TO THE ENGINE WHILE THE ENGINE IS RUNNING (E.G. CARBURE- TOR), KEEP CLEAR OF ALL MOVING PARTS. BE CAREFUL OF HEATED SUR- FACES AND MUFFLER. Minor carburetor adjustment may be required to com- pensate 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 CARBURE- TOR. DO NOT MAKE UNNECESSARY ADJUST- MENTS. FACTORY SETTINGS ARE SATISFACTO- RY FOR MOST APPLICATIONS AND CONDITIONS. Never attempt to change maximum engine speed. It is pre-set at the factory and should be changed only by a qualified service technician who has the necessary equipment. The carburetor may need re-adjusting if engine lacks power or does not idle properly. If adjustments are needed, proceed as follows. ⢠Close idle mixture valve (see figure 24) clockwise ( f'_ ) finger tight only. Forcing may cause damage. Then open 1-1/2 turns counterclockwise ( ,,_ ). ⢠Start engine and allow to warm for five minutes. ⢠Move throttle control lever to IDLE position. ⢠Rotate throttle counterclockwise (,,_) and hold against idle speed adjusting screw. Turn idle speed adjusting screw until engine is running at 1750 RPM. ⢠Turn idle mixture valve clockwise (¢-_) (lean mix- ture) until engine JUST starts to slow. Then turn it counterclockwise (,,--,) (rich mixture) until engine starts to run unevenly. Set at midpoint between rich and lean mixture. ⢠Recheck idle RPM and readjust if necessary. ⢠Move throttle control lever to FAST position. Engine should accelerate without hesitation or sputtering. If it does not, carburetor should be read- justed, usually to a slightly richer mixture. Speed Screw Throttle Idle Mixture Valve FIGURE 24. ENGINE SPEED Your engine speed has been factory set. Do not attempt to increase engine speed or it may result in personal injury. If you believe the engine is running too fast or too slow, take your chipper-shredder to the nearest SEARS Service Center for repair and adjust- ment. TIRES Recommended operating tire pressure is 24 p.s.i. (sidewall of tire may give tire manufacturer's recom- mended pressure). Equal tires pressure should be maintained on both rires. When installing a tire to the rim, be certain rim is clean and free of rust. Lubricate both the tire and rim generously. 15
