Hold tree limbs and branches carefully to maintain control as they are being fed into the chipper cone, letting the self-feeding action of the unit pull the material in. 11 Operation *2572*2573 Figure 7. Proper Stance for Chipping Never wrap your fingers around tree limbs and branches so tightly that you can’t let go quickly if the tree limb or branch is suddenly pulled into the chipper block or shredder hopper area. Leaves and other lightweight organic matter can be quickly shredded in your chipper/ shredder and reduced to 1/20th of their original volume. Place material to be shredded into the shredder hopper. Avoid large amounts of wet material that can cause shredded matter to build up in the discharge chute and prevent proper discharge. Alternate the processing of dry and wet materials to help prevent clogging of the discharge chute. When time permits, let wet material dry out for a few days prior to shredding. Properly Feeding Longer Materials For Shredding When processing brush, small branches, or other long types of organic matter, feed the materials to be shredded into the shredder hopper lengthwise, butt end first, to prevent clogging of the hopper. If brush gets tangled and clogged as it’s being fed into the hopper, never reach into the hopper to clear it while the unit is running. Shut the engine off, let the rotor come to a complete stop, and disconnect the spark plug before attempting to clear the hopper. NOTE:Be sure to shut off the engine and allow the rotor to stop completely before emptying the bag. Figure 8. Feeding Materials For Shredding *2574 Figure 9. Properly Feeding Longer Materials for Shredding 12 Operation MATERIAL PROCESSING General Most materials to be processed can be handled more efficiently by observing the following chipper/shredder operating tips: Shredding 1. Don’t overload the shredder hopper by dumping large volumes of material into the hopper opening. 2. Alternate wet and dry material to prevent the discharge chute from becoming plugged. 3. Never use any object to force material into the shredder chamber. It could get caught in the shredding hammers and damage the unit, reducing shredder hammer effectiveness. Chipping 1. Prune tree limbs and large branches to limit size to the maximum diameter allowed. Pruning tree limbs and branches close to the main portion of the limb or branch will make feeding into the chipper cone easier, and will help you maintain control as the material is drawn into the chipper block. 2. Large, hard, or dried-out tree limbs that tend to resist chipping can be processed by rotating them manually as you alternately insert and retract them in the chipper cone. 3. If the material to be chipped is extremely hard and kicks back forcefully, or cannot be easily controlled while it is being fed into the unit, remove the material immediately and set it aside. You may need to sharpen the chipper blades to process the material. Consult the maintenance and service section of this manual for sharpening instructions, or take your unit to an authorized service center for prompt, reliable service. 4. If normal chipping operation begins to require additional feeding force to process material, the chipper knives may be in need of routine sharpening. See the maintenance and service section of this manual for sharpening instructions, or take your unit to an authorized service center for prompt, reliable service. 5. Always try to maintain adequate control of the tree limbs and branches being fed into the chipper cone to prevent them from whipping around and causing injury to you or damage to the cone. Larger limbs and branches may have a tendency to kick back toward the operator, so always be alert as you feed materials into the cone. 6. Cut any left-over material into 1" pieces and process them through the shredder hopper. SHUTTING DOWN DANGER Engine and surrounding parts become extremely hot during normal use, and will cause serious burn injuries if touched before the engine has cooled. Allow engine to cool completely before touching these hot surfaces. When you’re done using the chipper/ shredder, following these simple but worthwhile steps will help you shut down the unit properly so that your next use will be trouble- free. 1. When you have completed processing the materials to be chipped or shredded, shut the engine off and allow the rotor to come to a complete stop before proceeding. 2. Remove the spark plug wire from the spark plug to prevent the possibility of inadvertent starting. 3. Inspect the following areas for any remaining materials that may have built up or become caught during the final chipping and shredding operations: • SHREDDER HOPPER Visually inspect inside of shredder hopper, and remove any material remaining inside. • CHIPPER CONE Visually inspect chipper cone to ensure that there are no pieces of tree limbs, branches, or any other debris remaining inside. Remove and discard this debris. • DISCHARGE CHUTE Lift the discharge deflector, and in...
