Introduction MODEL IDENTIFICATION l l l Record your model number, manufacturer number and serial numberfrom the I.D. tag in the space provided t for easy reference. The Chipper Vacuum I.D. tag is located on the side of the unit as shown in the illustration below. Refer to the engine manufacturer’s owner’s manual for the location of the engine serial number. Model Mfg. No.
DESCRIPTION rocks, gravel, and other debris before use. All materials and other debris that could damage the shredding hammers should be removed and properly disposed of before starting the unit. General The shredding chamber is designed to shred materials that have been vacuumed directly into the unit through the extra-wide vacuum intake nozzle or through the flexible vacuum hose, eliminating the need to manually load or feed material into the shredder.
A The Safety Alert symbol shown to the left is used to alert you to important safety information that must be read, fully understood, and followed at all times when handling, transporting, operating, servicing, or storing your Chipper Vacuum. Each safety alert symbol is followed by a “signal word” that advises you of the relative intensity, or level, of the hazard the safety alert instructions pertain to.
l l l l l Never store the fuel container or Chipper Vacuum indoors where there is a possibility of contact with any ignition source such as a spark, open flame, pilot light, heating element, or smoking materials. A CAUTION SPARK/FIRE HAZARD GAS ENGINES MAY REQUIRE A SPARK ARRESTER FOR SAFE OPERATION Never attempt to test or operate the unit indoors or in an enclosed area. Engine exhaust contains carbon monoxide, an odorless, colorless, and tasteless gas.
Safety Rules l l l l l l l Never leave the machine running unattended. Always turn off the engine, wait ior the rotor to come to a complete stop, and disconnect the spark plug before leaving the area. Always move the unit to a safe storage area for prolonged idle periods. followina: Never allow children to operate the machine. Do not allow adults to operate it without proper instruction. b. Check for loose parts, and loose or missing hardware, and repair or replace as reauired.
Safety Rules storage preparations before storing the unit for prolonged periods. equipment can result in serious injury, damage to equipment, and voiding of your warranty. TRANSPORTING AND STORAGE l l l l l l If you must travel across rock, gravel, or other debris-covered terrain, set the engine speed control to Wow”, and close the variable suction control flap by moving the selector lever to the “closed” position. Never lift the unit using the fuel tank, vacuum intake areas, or covers for support.

CONTROLS A. Choke The choke controls the fuel to air ratio, and helps make cold starts easier by providing a rich, easily-ignited fuel mixture. B. Throttle The throttle controls engine speed, and allows you to conserve fuel by powering down during idle periods, or to achieve optimal chipping/shredding/vacuuming power by running the engine at full speed. C.
Operation 2. Inspect the chipper cone and make sure that it is firmly attached to the shredder housing. SITE LOCATION 1. Select an area that will provide stable footing for both the Chipper Vacuum and the operator. Do not operate on wet, slippery surfaces, or in areas with heavy pedestrian traffic that may distract you from alert operation of the unit. 3. Check all parts to ensure that they are properly attached and that all fasteners are properly tightened. 4.
Operation Starting The Engine - Manual Start Units 1. Move choke lever to full choke position. 2. Move throttle lever to “fast”. 3. Place foot on front wheel to hold unit firmly in place, and adopt a stable stance. 4. Pull starting rope out slowly one time and allow to return normally. Choke & throttle controls 5. Pull starting rope out with a steady pull, and allow rope to return normally. 6. When engine starts, gradually move choke lever to “no choke” position. 7.
Operation Drive Speed Selector Speed Selector Lever Forward speed is selected using the speed control lever mounted on the right side of the handle. The speed control lever has three positions: slow, medium or fast (Figure 3). The ability to select different speeds for differing types of waste material pick-up and varying surface conditions helps give you precise control over the unit, which is further enhanced by the 3-position vacuum height adjustment and 4-position vacuum intake opening adjustment.
Operation l l l Hold tree limbs and branches carefully as they are being put into the chipper cone, releasing your grip as soon as the self-feeding action of the chipper knives begin to pull the material in. Longer pieces may have a tendency to twirl around forcefully as they are being drawn into the chipping knives. Hold the material safely away from the chipper cone area until the material is properly controlled by the chipper cone.
Operation 4. lnserl the connector end of the vacuum hose into the intake opening, using care to fully seat the connector in the opening. If the connector is not fully inserted, and electrical interlock switch will keep the unit from starting or running (Figure 6). 5. Place the hand-held vacuum intake nozzle in the area to be vacuumed, using care to avoid twisting and minimize bends in the hose. 6.
Operation 2. Remove the spark plug wire from the spark plug to prevent the possibility of inadvertent starting. On electric-start models, remove the key to prevent anyone from inadvertently activating the electric start feature. Although the unit won’t start with the spark plug removed, the rotor will turn, and serious injury could result if your hands are in the area of the rotor or chipper knives. 3.
Operation A safe collection area should be located where children, pets, and bystanders will not come into contact with chipped material as it is being discharged, or be hit by deflected pieces that may ricochet away from the collection area with great force. When using direct discharge, check the discharge area frequently for accumulation of material near the discharge port, and make sure the material can be safely ejected away from the unit.
Operation slides smoothly into place in one of four slots (Figure 9). To adjust the opening of the vacuum intake nozzle flap: l 1. Grip the curved portion of the lever arm, 2. Pull the lever out of the present slot, 3. Slide the lever into the desired slot. l Vacuum Intake Nozzle Height Position The vacuum intake nozzle height adjustment is located at the rear of the frame on the left side of the unit (Figure 10). This adjustment controls the height of the vacuum intake nozzle above the ground.
If you are unsure about processing a material not covered in the guide below, contact your local authorized dealer, or call our Customer Service Department at 414-284-6786 for assistance before proceeding. WASTE MATERIALS GUIDE Your Chipper Vacuum is designed to efficiently process a wide variety of organic yard and garden waste materials.
Normal Care SCHEDULED MAINTENANCE Your Chipper Vacuum has been designed to provide you with years of reliable operation. Keeping your Chipper Vacuum 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. Please read this normal care schedule, and observe these recommended care operating intervals to extend the life of your unit.
NormalCare Clean Engine Air Intake Area The engine is air-cooled, and requires unobstructed air flow into and around the engine. The cooling fins on the engine cylinder head area must also be kept clear of chipper and shredding deposits, as well as any other build-up of debris that could prevent heat from radiating away from the engine (Figure 14). To clean the air intake area, remove any external material build-up, and then blow out the area using a stream of compressed air.
Normal Care and clean out if required. Always shut engine off and remove the spark plug wire from the spark plug before reaching into the housing to clear material. fluid levels to run down below full may result in erratic starting performance, or inability of the battery to provide adequate power to operate the starter motor. For stubborn debris, the vacuum nozzle housing can be removed from the unit following the steps in the hammer service section of this manual, and hosed out with a garden hose.
Storage TEMPORARY STORAGE l (30 Days Or Less) l Here’s a quick checklist of things to do when storing your Chipper Vacuum temporarily, or between uses: l l l l l l l l Keep the unit in an area away from where children may come into contact with it. When this equipment is stopped for service, inspection, or storage, or to change an accessory, operators shall make sure the spark plug wire is disconnected from the spark plug.
