This is a normal sound. If this sound continues after the machine obtains full speed, please contact your dealer for an inspection of your chipper/shredder. WARNING Engine exhaust from this product contains chem- icals known, in certain quantities, to cause caner, birth defects, or other reproductive harm.
Although the instructions and warnings appearing in this all times when manual cover most normal operating conditions, every- one using the chipper/shredder unit must also always fol- low safe work practices while operating, servicing, or handling the chipper/shredder unit under any conditions not specifically covered in this manual.
Never lean directly over the machine. 4. Always stand to the side of the chipper cone when feeding tree limbs and branches into the unit, as tree limbs, branches, and harder woods may whip around while being chipped.
Should any of these labels become unreadable because of being worn, faded, or otherwise damaged during the use of your chipper/shredder, please use the part num- ber information provided to order a replacement label from your local authorized dealer.
Be sure to clean all hardware threads of paint and debris before assembling. CHIPPER CONE 1. See figure 1. Position the chipper cone assembly base over the three 5/16-18 threaded studs protruding from the engine plate, and attach using (3) 5/16-18 whiz nuts.
See figures 5A & 5B for installation. ENGINE OIL Fill the engine oil sump with SAE 30 oil (5W30 for winter use). See page 16 for additional information and the location of the fill-plug, or consult the engine manufactur- er’s literature shipped with your chipper/shredder. Assembly...
• The Support Leg & Wheels • Fan/Rotor Housing Each of these major components serves a specific func- tion on the chipper/shredder. Please take a moment and familiarize yourself with the name, location, and function of these components so that you will better understand the safety and operating instructions provided in this manual.
Chipper Operation The chipper is designed to handle tree limbs and branch- es up to 3" in diameter (2-1/2" on Model 5/14). The pow- erful motor and durable chipping knives also permit the unit to process tough organic matter such as corn stalks and berry canes.
•. no fuel has spilled onto engine or surrounding components. •. all hardware and parts are properly secured. •. no foreign objects are in chipper cone or shredder hopper. •. your clothing is not excessively loose or hanging down, and you are not wearing jewelry or other articles that could get caught in the machinery.

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 shred- der 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.
You may need to sharpen the chipper blades to process the material. Consult the mainte- nance and service section of this manual for sharpen- ing instructions, or take your unit to an authorized ser- vice center for prompt, reliable service.
Operation WASTE MATERIALS GUIDE Your chipper/shredder is designed to efficiently process a wide variety of organic yard and garden waste materi- als. To obtain consistent performance, extend the life of your unit, and help ensure safe operation, do not attempt to process non-organic materials, and always follow the material requirements shown in the Waste Materials Guide below.
Your chipper/shredder has been designed and produced by the industry’s leading manufacturer of outdoor power equipment to provide you with years of reliable operation. Keeping your chipper/shredder in top running condition will prolong its life, and help you obtain optimum performance whenever you wish to chip or shred yard or garden waste.
WARNING Never drain oil immediately after running the chipper/shredder, as it will be hot and could cause burns if allowed to splash onto your hands or body. 2. Dispose of used oil by returning it to an oil recycling center or service station with a oil recycling tank.
For proper engine cooling, the cool- ing fins on the engine cylinder head area must also be kept clear of chipper/shredder deposits, as well as any other build-up of debris that could prevent heat from radi- ating away from the engine.
Contact your local authorized dealer for replacement if these parts need to be replaced. Inspect Chipper Cone & Shredder Hopper The chipper cone and shredder hopper are made of a highly durable polyethylene material that can withstand repeated abrasion and impact from normal chipper/shredder waste material processing.
(30 Days Or Less) Remember, the chipper/shredder fuel tank probably will still contain some gasoline, so never store the chipper/ shredder indoors or in any other area where fuel vapor could travel to any ignition source. Fuel vapor is also toxic if inhaled, so never store the chipper/shredder in any structure used for human or animal habitation.
Troubleshooting & Repair TROUBLESHOOTING While normal care and routine maintenance will extend the life of your chipper/shredder, prolonged or constant use may eventually require that service be performed to allow it to continue operating properly. The troubleshoot- ing guide below lists the most common problems, causes and remedies.
*2557 Figure 16. Triangular Hammer Wear Area REPAIR Engine Service Your chipper/shredder engine requires routine mainte- nance for long-life and trouble-free operation. Consult the manufacturer’s manual provided with this unit for specific recommendations and service procedures. In general, however, your engine requires only the preven- tive maintenance indicated on the Normal Care Schedule.

Troubleshooting & Repair 4. Using leather work gloves to protect your hands from sharp edges, carefully rotate the rotor counterclock- wise until the first worn hammer is at the top position. 5. Before proceeding, note the assembly sequence of the hammer, spacer, spacer tube, and hardware. Hammers and spacers must be reassembled in the same order to ensure proper rotor balance, shredding efficiency, and safety.
Rapid grinding and heating of blades will soften the edges, making repeated sharpening necessary. • Chipper knives require a 30° bevel on the cutting edge (as shown in Figure 22) for efficient chipping action. • Contact your local dealer or blade sharpening ser- vice if you prefer not to sharpen the blades your- self.
Vacuum Attachment This easy-to-add accessory allows the chipper/ shredder to be equipped with a vacuum hose and other attach- ments to help simplify pick up of lightweight materials such as leaves and grass clippings.
