Small branches up to 1/2" diameter can also be fed into the shredder in this position. See figure 11. FIGURE 8.—Model 645 Shown T ...........[U,MUI„ FIGURE 10. No Larger Than 1/2" Diameter FIGURE 11. 3. To lower the leaf ramp, use one hand to grasp the handle at the top of the leaf ramp and lift slightly. Pull up on the release bar, and lower the leaf ramp to the ground. Release the bar. See figure 12. Bulky material, such as stalks or heavy branches, up to 3" in diameter should be fed into the chipper chute. See figure 13. A WARNING: Make certain leaf ramp is raised as shown when using the chipper chute. Also 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 Maintenance section on page 8. For best performance, it is important to keep the shredding blade and the chipper blades sharp. Refer to Maintenance section, pages 8 and 9. 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. MAINTENANCE A WARNING: Always stop engine and disconnect spark plug wire before cleaning, lubricating or performing any repairs or maintenance. LUBRICATION Lubricate the pivot points on the release bar, leaf ramp, chute deflector and chipper chute once a sea-v son using a light oil. ENGINE Refer to the separate engine manual for engine maintenance instructions. Maintain engine oil as instructed in the separate engine manual packed with your unit. Read and follow instructions carefully. Service air cleaner every 25 hours under normal conditions. Clean every few hours under extremely dusty conditions. Poor engine performance and flooding usually indicates that the air cleaner should be serviced. To service the air cleaner, refer to the separate engine manual packed with your unit. The spark plug should be cleaned and the gap reset once a season. Spark plug replacement is recom- 7 I mended at the start of each season; check engine manual for correct plug type and gap specifici tions. Clean the engine regularly with a cloth o' brush. Keep the cooling system (blower housing area) clean to permit proper air circulation which is essantial to engine performance and life. Be certain to re nove all dirt and combustible debris from muffler area. CLEANING The shredder may be cleaned by running wster from a hose through the hopper assembly and chipper chute with the engine running. Allow the shrodder to dry thoroughly. Wash the bag periodically with water. Allow to dry thoroughly in the shade. Do not use heat. REMOVING THE FLAIL SCREEN If the discharge area becomes clogged, rerrove the flail screen and clean area as follows. 1. Stop the engine, make certain the shrecder has come to a complete stop and disconnect spark plug wire from the spark plug before unclogging the chute. 2. Loosen the two hand knobs on each sids of the chute deflector. Lift the chute deflector up and tie it out of the way. 3. 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 14. 4. Clean the screen by scraping or washing with water. Reinstall the screen. NOTE: Be certain to reassemble the flail sen >en with the curved side down as shown in figure 14. Hand Knobs FIGURE 14. SHARPENING OR REPLACING CHIPPER BLADES 1. Disconnect spark plug wire and move it away from spark plug. 2. Remove the flail screen as instructed in previous section. 3. Remove the chipper chute by removing three hex nuts and washers. A 1/2" wrench is required. See figure 14. NOTE: When reassembling, the cupped washer goes on the bottom of the chipper chute with the cupped side against the chute. 4. 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 15. 5. 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 15 (sharp edge is assembled toward the slotted opening in the impeller assembly). SHARPENING OR REPLACING SHREDDING BLADE The shredding blade may be removed for sharpening or replacement as follows. 1. Disconnect spark plug wire and move it away from spark plug. 2. Lower the leaf ramp. Block up the housing. See figure 16. 3. Remove the six hex lock nuts and lock washers from the housing weld bolts using a 1/2" wrench. Separate the shredder into two halves...
