#940-0011 #930-0013 Protecting Yourself and Those Around You This is a high-powered machine, with moving parts operating with high energy. You must operate the machine safely. Unsafe operation can create a number of hazards for you, as well as anyone else in the nearby area. This machine can crush, grind, cut, and sever parts of your body if they enter the inlet or discharge area of your shredder-chipper.
General Safety Operating this shredder-chipper safely is necessary to prevent or minimize the risk of death or serious injury. Unsafe operation can create a number of hazards for you. Always take the following precautions when operating this machine: • Your shredder-chipper is a powerful tool, not a plaything. Exercise extreme caution at all times. The machine is designed to chip wood and shred most organic materials. Do not use it for any other purpose.
A Note to All Users Under California law, and the laws of some other states, you are not permitted to operate an internal combustion engine using hydrocarbon fuels without an Engine Spark Arrester. This also applies to operation on US Forest Lands. All shredder-chippers shipped to California, New Mexico, and Washington State are provided with Spark Arresters.
Section 2: Setting Up The SHREDDER-CHIPPER It may be helpful to familiarize yourself with the controls and features of your shredder-chipper as shown in Figure 1 before beginning these procedures.
Unpacking the SHREDDER-CHIPPER Tools and supplies needed: • • • • • 1/2" Wrench Hammer Pry Bar Wire Cutters or Utility Knife Safety Glasses Wear Safety Glasses to protect your eyes from flying debris and Gloves to protect your hands from sharp objects when performing these procedures. 1. Use a Hammer and Pry Bar to separate the bottom Crate Boards from the Pallet and lift the Crate off the Pallet. 2. Cut the Straps that are securing the machine to the Pallet. 3.
Section 3: LUBRICATION & ENGINE START UP FOR INFORMATION ABOUT: ❑ ❑ ❑ ❑ ❑ ❑ ❑ ❑ OIL FUEL STARTING STOPPING RECOMMENDED MAINTENANCE SERVICE STORAGE ENGINE WARRANTY INFORMATION REFER TO THE ENGINE OWNER’S MANUAL. THE ENGINE ON YOUR SHREDDER-CHIPPER HAS BEEN SHIPPED DRY. BE SURE TO SERVICE THE ENGINE ACCORDING TO THE ENGINE OWNER’S MANUAL PRIOR TO STARTING. FAILURE TO DO SO CAN RESULT IN DAMAGE NOT WARRANTIED BY THE ENGINE MANUFACTUROR.
Section 4: OPERATION DANGER: Rotating cutting blades. Keep hands and feet out of inlet and discharge opening while machine is running. This machine can CRUSH, GRIND, CUT, and SEVER parts of your body if they enter the inlet or discharge area of your shredder-chipper. Whenever you operate your shredder-chipper, wearing gloves and safety glasses is required. If necessary to push material into shredding chamber, use a wood stick, never hands or steel implements.
Before You Begin • Visually check the Chipper Knife for damage each time you use the machine. NOTE: Check for shaft movement while starting the Engine. If the shaft does not turn, STOP the Engine and clean out the Shredder-Chipper Hopper(s) as instructed on page 14. • ALWAYS operate the shredder-chipper from the Operator Zones (Figure 5). • When viewed from the Chipper Hopper side the Rotor turns in a clockwise direction. • NEVER assume you know where the Chipper Knife is. You do not know where it is.
Processing Material Read and understand the warnings listed in “Section 1 General Safety Rules” before operating this shredder-chipper. • Your shredder-chipper can process dry or green material. • Green material will process quicker and easier than dry material. • Soft wood processes easier than hard wood. • Your operator experience will teach you how different materials chip/shred and how fast you can process different materials.
If you jam the machine and do not stop the Engine, it can damage the machine. This damage can be costly and not covered under warranty. See “To Free a Jammed Flywheel” on page 14. Using the Shredder Hopper The Shredder Hopper is located on the top of the shredder-chipper and is the opening into which all materials to be shredded should be fed. You can shred most organic materials. A flex guard, or blowback shield is attached to the Hopper.
To Free a Jammed Rotor Before performing any maintenance procedure or inspection, stop the Engine, wait five (5) minutes to allow all moving parts to come to a complete stop and cool. Disconnect the Spark Plug Wire, keeping it away from the Spark Plug. 1. Remove any material left in the Chipper and Shredder Hoppers with a wooden stick. Nut 2. Check the Discharge Opening for clogs. If it is clogged, clear it with a stick. 3.
Section 4: Maintaining the SHREDDER-CHIPPER Regular maintenance is the way to ensure the best performance and long life of your machine. Please refer to this manual and the Engine Manufacturer's Owner's Manual for maintenance procedures. Service intervals listed in the checklist below supersede those listed in the Engine Manufacturer's Owner's Manual. Before performing any maintenance procedure or inspection, stop the Engine, wait five (5) minutes to allow all parts to cool.
Grease Fittings Your shredder-chipper was greased at the Factory. The operator needs to lubricate the Chipper Side and Drive Side Bearings periodically. Tools and Supplies Needed: • • • • • Flexible hose grease gun Grease Clean cloth 5/32" Allen Wrench Loctite® 243 (if set screws are loose) 1. Wipe all dirt, etc., from the Grease Fittings on both Bearings with a clean cloth (Figure 9). 2.
5. Loosen the four Engine Bolts using two 1/2" Wrenches (Figure 12). 6. Using a 1/2" Wrench, turn the Tag Nut away from the Adjust Nut. 7. Turn the Adjust Nut in against the Frame to tighten (if Belt is too loose) or out to loosen (if Belt is too tight) for the correct Belt tension. 8. When the Belt is at the proper tension tighten the Engine Hardware. 9. Screw the Tag Nut up to the Adjust Nut. 10. Replace the Baffle Plate and Belt Guard.
c) Remove the two Set Screws with a 5/32" Allen Wrench (Figure 14). d) Remove the Retaining Ring with the Retaining Ring Pliers e) Remove the Shims and Rotor Pulley from the shaft. Note: Make sure the Shaft Key stays in the slot of the Shaft when the Pulley is removed. If it does come out of the slot, slide it back in for assembly. f) Place enough Shims on the Shaft to equal the measurement you wrote down.
Replacing the Chipper Knife Shredder Tools and Supplies needed: Shredder Figure 17 • • • • Two 1/2" Wrenches 3/16" Allen Wrench Awl Gloves 1. Use two 1/2" Wrenches to remove the Shredder Hopper (Figure 17). 2. Use a 1/2" Wrench to remove the Chipper Hopper. 3. Rotate the Rotor Assembly using a stick until the three countersunk Allen Screws attaching the Knife to the Rotor are visible through the Chipper Hopper Opening (Figure 18). 4.
Maintaining the Shredder Hammers When the hard steel Hammers of the Rotor Assembly become dull or round on the cutting edge, they may be rotated or reversed. NOTE: The Hammers have four cutting edges that may be used before replacement is necessary. To reverse the Hammers, proceed as follows: Tools and Part Required • Two 1/2" Wrenches • Hammer and Punch 1. Remove the Baffle Rod and Cotter Pin to remove the Baffle Plate (Figure 21). 2.
Removing and Replacing the Clutch The design of the Clutch on your machine is for rugged, dependable service, however, it is important to understand the limitations of a Clutch. The Clutch design is to provide load free starting of the Engine, and slippage under excessive overloading of the driven application. These features help protect the Engine from damages such as broken crankshafts and starters. The Clutch on this machine is permanently lubricated and does not require oil or grease.
Section 5: Troubleshooting Most problems are easy to fix. Consult the Troubleshooting Table below for common problems and their solutions. Shut down the Engine, remove the Spark Plug Wire, and wait 5 minutes before performing any maintenance procedure or inspection on the Shredder-chipper. Troubleshooting Table SYMPTOM Recoil will not pull out or is difficult to pull. POSSIBLE CAUSE Remove any built-up debris from the Shredder/Chipper Hopper Inlet(s) and Discharge Chute.
Engine smokes. (Please refer to the Engine Owner’s Manual for engine-specific procedures.) Check the oil level and adjust as needed. You may be operating the machine on too great an incline. The machine should be level. The Air Filter may be dirty; change it following the procedure in the Engine Owner’s Manual. You may be using the wrong oil - too light for the temperature. Refer to your Engine Owner’s Manual for detailed information. Check that the Cooling Fins are clean and free of debris.
