STEP II – ATTACHING THE HITCH ASSEMBLY • Place the base on Jack Stands so that the frame is level with the ground (Figure 2). • Position the Support Leg in the down position and secure using the Pin and Hitch Clip (Figure 3). • Attach the rear of the Tow Bar to the Rear Frame Support using a 3/8”-16 x 3” bolt and a 3/8-16 Nylon Locknut and secure loosely. • Attach the Tow Bar to the Front Frame Support using a 3/8”-16 x 3” bolt and 3/8-16 Nylon Locknut and tighten using two 9/16” wrenches.
STEP III – ATTACHING THE SHREDDER HOPPER • Place the shredder hopper (item #2) onto the basic unit (item #1) making sure the shredder hopper flange is up against the top plate allowing minimal or no gap. • Secure the front two bolts (item #6) and locknuts (item #5) towards the discharge end. • Secure the rear two bolts and locknuts which is the flat side of the shredder hopper. • Tighten the top screen bolt and locknut on the basic unit so at least 2 threads of the bolt stick out beyond the lock nut.
STEP IV – ATTACHING THE CHIPPER HOPPER • Attach the chipper hopper (item #4) to machine using four each 5/16”-18 x 3/4” carriage bolts (item #51), 5/16” flatwashers (item #47) and 5/16”-18 nylock nuts (item #10). Put head of bolt inside hopper with threads sticking out. Tighten all hardware with a ½” wrench.
SECTION III – LUBRICATION & ENGINE START UP BEFORE STARTING ENGINE, ALWAYS CHECK OIL LEVEL! Refer to the engine owner’s manual for further details regarding OPERATION AND MAINTENANCE OF the engine. NOTE: ENGINE IS SHIPPED WITHOUT OIL! FILL CRANKCASE WITH OIL BEFORE STARTING ENGINE. BE VERY CAREFUL NOT TO ALLOW DIRT TO ENTER THE ENGINE WHEN CHECKING OR ADDING OIL OR FUEL. NOTE: IF YOU START THE ENGINE WITHOUT OIL, THE ENGINE WILL BE DAMAGED BEYOND REPAIR AND WILL NOT BE COVERED UNDER WARRANTY.
CHECKING AND ADDING OIL • Check oil level before starting the engine. • Check level daily, or after every eight hours. • Keep oil level at FULL. • Do not overfill. Oil filling procedure: first add 1 quart. Start and run engine at idle for 30 seconds. Shut engine off and wait 30 seconds. Then add more oil slowly to bring level to Full mark on dipstick. Oil checking procedure: before starting engine, check oil level. • Place engine level. Clean around oil fill and dipstick.
STARTING AND STOPPING STARTING AND OPERATING TIPS • Store and fuel equipment in level position. • Use fresh fuel. • Use correct type of oil for expected starting temperature. • Remove external equipment/engine loads. • Periodically remove any debris buildup from the machine. • After engine has started, let it warm up several seconds to several minutes, depending on outside temperature. • For maximum performance and life, operate engine with choke in RUN and throttle in FAST.
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 ½” in diameter. Cut your materials into manageable lengths before feeding them into the chipper.
USE COMMON SENSE WHEN USING YOUR SHREDDER/CHIPPER. • LEARN TO RECOGNIZE THE CHANGE IN THE SOUND OF YOUR MACHINE WHEN IT IS OVERLOADED. • BECOME FAMILIAR WITH SUCCESSFUL OPERATING CONDITIONS AND AVOID THOSE THAT CAN OVERLOAD AND DAMAGE THE MACHINE. • IF THE MACHINE BECOMES JAMMED BY OVERLOADING OR ANY OTHER CAUSE, STOP THE MACHINE IMMEDIATELY. • IF YOU JAM THE MACHINE AND DO NOT STOP THE ENGINE, IT CAN DAMAGE THE MACHINE. THIS DAMAGE CAN BE COSTLY AND IT MAY NOT BE COVERED UNDER WARRANTY.
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.
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.
