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.

Cut plastic tie attaching tow tongue to axle and pull tow tongue forward. Lower machine back down to all 4 wheels. Your machine is ready for further assembly.
STEP IIa – Connecting the Battery Cable (Electric Start) (on 12PTE only) We ship the electric-start with the negative terminal battery cable disconnected. This prevents the battery from discharging during shipment. Before using your electric start, you must connect the battery cable. 1. Slide the Terminal of the Negative Battery Cable onto the Negative Terminal Lug of the Battery. Negative Battery Cable Negative Cable Positive Cable Battery Positive Cable STEP III – INSTALLING THE CHIPPER HOPPER 1.
SECTION IV – INSTALLING THE SHREDDER HOPPER-FIG. 1 (If not installed from factory) 1. Place bolts (item #34,35) up through the machine and start to thread vibration dampeners on them to hold in place. Set shredder hopper (item #2) in place on the vibration dampeners and secure them tightly. Place nylock nuts (item #37) on in addition for added security.

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 MANUFACTURER.
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.
USING THE SHREDDER HOPPER • • • • • The shredder hopper is located on the top of the unit and is the opening into which all materials to be shredded should be fed. Most organic materials can be shredded. A flex guard, or blowback shield is secured to the hopper. Material must be pushed past this flap by using a wooden stick in order to enter the main shredding chamber where revolving steel hammers do the shredding. The blowback shield is an important feature.
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 3” 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 1/16 th” 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 with a wooden stick 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 another small 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 WITH A STICK. 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. 030-0164 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 the drum wobbles excessively after long periods of use, 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.
030-0611 CLUTCH BREAKDOWN Item Part No.
