SAFE OPERATION PRACTICES TRAINING Read this owner’s manual carefully in its entirety before attempting to assemble this machine. Read, understand, and follow all instructions on the machine before operation. Be completely familiar with the controls and the proper use of the machine before operating it. Keep this manual in a safe place for future and regular reference and for ordering replacement parts. Know how to stop the unit and disengage the controls quickly.
OPERATION Never place your hands, feet, or any part of your body in the shredder hopper, chipper chute, discharge opening, or near or under any moving part while the shredder/chipper is running. Keep clear of the discharge opening at all times. If it becomes necessary to push material into the shredder hopper or chipper chute, use a small diameter stick, NOT YOUR HANDS.
Keep area of discharge clear of people, animals, buildings, glass or anything else that will obstruct clear discharge, cause injury or damage. Wind can also change discharge direction, so be aware. Do not allow an accumulation of processed material to build up in the discharge area as this will prevent proper discharge and can result in kickback from the shredder hopper or chipper chute.
OPERATOR ZONE Only operate your shredder/chipper from the operator zone. Know how to turn your unit off. Never move your shredder/chipper or leave it unattended with the engine running. Follow engine owner’s manual for engine maintenance and repair. YOUR RESPONSIBILITY Restrict the use of this power machine to persons who read, understand, and follow the warnings and instructions in this manual and on the machine.

SECTION III - 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 CHIPPER SHREDDER 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 IV – SHREDDING & CHIPPING THIS SHREDDER/CHIPPER WAS DESIGNED FOR SHREDDING LEAFY GARDEN OR ORGANIC MATERIAL AND CHIPPING LIMBS OR BRANCHES. NEVER USE THIS MACHINE FOR ANY OTHER PURPOSE AS IT COULD CAUSE SERIOUS INJURY. CONTACT WITH INTERNAL ROTATING HAMMERS WILL CAUSE SERIOUS PERSONAL INJURY. DO NOT PUT HANDS, FACE, FEET OR CLOTHING INTO THE SHREDDER HOPPER, CHIPPER CHUTE, DISCHARGE OPENING OR NEAR THE DISCHARGE AREA AT ANY TIME.
When chipping branches, sometimes a tail will be left at the end of a branch. To avoid this, rotate the branch as it is fed into the chute. Rotating the branch as you feed it into the machine will improve chipping performance. An optional screen is available for greater reduction of the material being processed through the shredder hopper.
USING THE CHIPPER HOPPER This chipper-hopper is mounted on the side of the machine and is designed to chip the larger, heavier materials that the shredder-hopper isn’t designed to handle. Branches fed into the chute are turned into “chips” by the revolving chipper knife mounted on a flywheel. The chipper-hopper can chip branches and vines ranging in size from 1” to 4” in diameter. Cut your materials into manageable lengths before feeding them into the chipper.
SECTION V – MAINTENANCE & STORAGE IMPORTANT: The knife should be checked for sharpness and the bolts attaching them to the flywheel for tightness every 8-10 hours of operation. IMPORTANT: Every time you perform maintenance or any kind of service or check on the knife, be sure to check the gap between the knife and wear plate for proper setting. NOTE: A knife gauge has been provided with your machine. It is 1/16th” thick and should be used to set the correct gap between the knife and wear plate.
REMOVAL, SHARPENING AND RE-INSTALLATION OF CHIPPER KNIFE HOW TO REMOVE THE KNIFE Stop the engine. Remove spark plug wire(s) and keep away from spark plug(s). Disconnect battery at negative terminal. Open the access cover on the chipper basic machine. Rotate the chipper disk until the three countersunk screws attaching the knife to the flywheel are visible through the access door. Clean out the heads of the allen screws with an awl or sharp tool.
The knife should never be sharpened to the extent that more than 3/32” is taken off this measurement. Once this measurement is below 7/32” (see figure 3) the knife should be replaced. If you are unable to remove dents or gouges with these guidelines, replace the knife. Figure 3 KNIFE INSTALLATION Clean chipper disk where knife is going to be attached.
AFTER ANY BLADE OR WEAR PLATE MAINTENANCE OR ADJUSTMENT, ROTATE THE CHIPPER DISK BY HAND. WATCH AND LISTEN CAREFULLY FOR ANY UNUSUAL NOISES, CLICKING OR VIBRATION. IF ANY OF THESE ARE DETECTED, INSPECT THE MACHINE FOR DAMAGE. REPAIR OR REPLACE ANY DAMAGED PARTS AND CHECK FOR ANY LOOSE PARTS AND RETIGHTEN.
INSTRUCTIONS FOR ADJUSTING OR REPLACING BELT BELT ADJUSTMENT The belt on your chipper should deflect 3/8” under three pounds of pressure as shown in figure 1 below. If it doesn’t, adjust per the following directions. Figure 1 Remove belt guard. Loosen engine bolts. Tighten or loosen the nut on the belt tensioner until you have the correct tension as shown in figure 1. Retighten engine bolts.
CENTRIFUGAL CLUTCH TECH TIPS CLUTCH PART NO. 030-0202 THE SHOES AND SPRINGS ON THE CLUTCH ARE NORMAL WEAR ITEMS. IF YOU NOTICE DECREASED PERFORMANCE OF THE CLUTCH THEY SHOULD BE CHECKED AND REPLACED IF NECESSARY. The clutch on your machine is designed for rugged, dependable service, however, it is important to understand the limitations of a clutch. A clutch is designed to provide load free starting of the engine, and slippage under excessive overloading of the driven application.
CLUTCH MAINTENANCE The centrifugal clutch on this machine is permanently lubricated and does not require oil or grease. More lubricant can be added to the bushing. Any standard motor oil is recommended. If, after long periods of use, the drum wobbles excessively, replace the drum assembly. Always replace shoes and springs in sets. Whenever shoes are changed, replace all springs. CLUTCH REMOVAL 1. Remove clutch from shaft by removing bolt and washers. 2. Slide clutch off shaft. 3. Remove key from keyway.
030-0202 CLUTCH BREAKDOWN Item Part No.
TROUBLESHOOTING SYMPTOM Clutch overheats. PROBLEM Clutch is slipping or flywheel is jammed or stopped. Belt burns. Flywheel won’t turn. Chipping action seems too slow or flywheel stalling. Engine speed is too slow. Belts are slipping. When chipping, log seems to vibrate excessively & “hammers” hands. Knife is dull. Gap between knife & wear plate is too great. Chipper knife is hitting wear plate. The gap between the knife and wear plate is set incorrectly. Inner shoes of clutch worn.
LUBRICATION AND MAINTENANCE OPERATION TIME PROCEDURE Change engine oil and filter after first five hours. Check belt tension. Check all nuts and bolts for tightness. Check engine oil. Check chipper knife for sharpness. Check knife and wear plate gap. Clean air filter. Grease bearings on basic chipper. * Change engine oil. ** Check tire pressure. Remove and sharpen or replace chipper knife. Sharpen wear plate. Replace belt. Change engine oil.
