MATERIAL UP TO A MAXIMUM OF 3" IN DIAMETER MATERIAL MAY BE FED INTO THE CHIPPER CHUTE. DO NOT ATTEMPT TO SHRED OR CHIP ANY MATERIAL LARGER THAN 3" IN DIAMETER. PERSONAL INJURY OR DAMAGE TO THE MACHINE COULD RESULT. No Larger Than 1/2" ^Diameter Hopper Assembly FIGURE 10. Leaves and small twigs can be raked into the hopper assembly when the hopper assembly is lowered to the ground. See figure 11. Small branches up to 1/2" diameter can also be fed into the hopper assembly in this position. See figure 12. FIGURE 11. 9 To lower the hopper assembly, use one hand to grasp the handle at the top of the hopper assembly and lift slightly. Pull up on the release bar, and lower the hopper assembly to the ground. Release the bar. See figure 13. Bulky material, such as stalks or heavy branches, up to 3" in diameter, should be fed into the chipper chute. See figure 14. A WARNING: MAKE CERTAIN THE CHIPPER CHUTE DOOR IS CLOSED WHEN NOT IN USE. 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 on page 13. For best performance, 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 discharged slows down considerably, it is likely that the shredding blade and/or chipper blades are dull and need to be sharpened or replaced. Refer to Service and Adjustments section, page 13. MAINTENANCE GENERAL RECOMMENDATIONS • Periodically check all fasteners and be sure they are tight. • Follow the Service Recommendation Schedule on page 15. CHIPPER-SHREDDER LUBRICATION Lubricate the pivot points on the release bar, guide extension assembly, chute deflector and chipper chute once a season using a light oil. ENGINE LUBRICATION Check engine oil level regularly—approximately every five hours of operation and before each usage. Stop engine and wait several minutes before checking oil level. With engine level, the oil must be to FULL mark on dipstick (refer to figure 7). Change engine oil after the first five hours of operation, and every twenty-five hours thereafter. • Drain oil while engine is warm. Remove oil drain plug. Refer to figure 7. Tip the chipper-shredder, and catch oil in a suitable container. 10 When engine is drained of all oil, replace drain plug securely. • Refill with fresh oil. Above 32°, use oil labeled SAE 30W or 10W30. Below 32°, use oil labeled 5W20. Capacity is approximately 11A pints. Refer to “Gas and Oil Fill-Up” on page 8. • Replace dipstick. 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: Clean cartridge at three month intervals or every 25 hours, whichever occurs first. See figure 15. Service more often under dusty conditions. • Loosen screws and tilt cover as illustrated. • Carefully remove pre-cleaner and cartridge. • Clean cartridge by tapping gently on a flat surface. If very dirty, replace cartridge and pre-cleaner or clean as follows: Wash in a low or non-sudsing detergent and warm water solution. CAUTION: Do not use petroleum solvents such as kerosene to clean cartridge. Rinse thoroughly with flowing water from inside out until water is clear. Allow cartridge to stand and air dry thoroughly before using. DO NOT OIL CARTRIDGE OR PRECLEANER. DO NOT USE PRESSURIZED AIR TO CLEAN OR DRY CARTRIDGE. • Install cartridge and pre-cleaner. Then close cover and fasten screws securely. Screw Screw Cover FIGURE 15. 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 contaminate the fuel system. Yearly or every 25 hours, whichever occurs first, remove the blower housing and clean the areas shown in figure 16 to avoid overspeeding, overheating and engine damage. Clean more often if necessary. A WARNING: PERIODICALLY CLEAN MUFFLER AREA TO REMOVE ALL GRASS, DIRT AND COMBUSTIBLE DEBRIS. Clean Out Chaff and Dirt FIGURE 16. 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 17. 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. FIGURE 17. 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 sc...
