  • What safety tips should I follow when operating the Craftsman 247.797852?

    When operating the chipper-shredder, always wear safety glasses provided with your unit or eye shields to prevent injury from ejected material. Other important safety rules include:

    • Never allow children to operate this equipment.
    • Do not operate while intoxicated or taking medication that impairs senses.
    • Avoid operating in the vicinity of children, pets, or other persons.
    • Never run the machine in an enclosed area due to carbon monoxide.
    • Never place hands, body, or clothing inside the feeding chamber, discharge chute, or near any moving part while the machine is running.
    • If inspection or repair is needed, stop the machine, allow it to cool, disconnect the spark plug wire, and move it away from the spark plug.
    • Handle gasoline with care as it is flammable. Check fuel before starting, and do not fill the fuel tank indoors, while the engine is running, or while hot. Turn the unit off and let the engine cool before refueling. Fuel in a clean area and do not smoke. Ensure the fuel tank cap is secure.
    • Operate only on a level surface and ensure all fasteners are properly secured.
    • When feeding material, be extremely careful not to include metal, rocks, bottles, cans, or other foreign objects.
    • If the cutting mechanism strikes a foreign object or the machine makes an unusual noise or vibration, immediately stop the engine, disconnect the spark plug wire, and inspect for damage, replace/repair parts, and check for loose parts.
    • Keep the engine clean of debris.
    • Do not allow processed material to build up in the discharge area.
    • Keep all guards and deflectors in place and in good working condition.
    • Always stand clear of the discharge area.
    • Keep face and body back from the feed opening to avoid bounce back.
    • Do not over-reach; maintain proper balance and footing.
    • Do not alter, change, or tamper with the engine governor settings.
    • Do not transport the machine while the engine is running.
    • Do not operate if the air cleaner or cover directly over the carburetor air intake is removed, except for adjustment.
    • When stopped for servicing, inspection, storage, or changing accessories, make sure the spark plug wire is disconnected and moved away, and allow the machine to cool down.
    • Do not use flammable solutions to clean the air filter.
    • Store the machine out of reach of children where gasoline fumes will not reach an open flame or spark.

    For more information, see pages 2 and 7 of the manual.

  • How do I start the Craftsman 247.797852 chipper shredder?

    To start the chipper shredder, ensure no one is standing near the unit and the chute deflector has been properly installed and secured with the hand knobs. Then, follow these steps:

    1. Attach the spark plug wire and rubber boot to the spark plug if necessary.
    2. Place the throttle control lever in the FAST position.
    3. Move the choke lever to the CHOKE position.
    4. Grasp the starter handle and pull the rope out slowly until the engine reaches the start of the compression cycle (the rope will pull slightly harder at this point). Let the rope rewind slowly.
    5. Pull the rope with a rapid, continuous, full arm stroke. Keep a firm grip on the start handle and let the rope rewind slowly, not allowing it to snap back against the starter.
    6. Repeat the preceding two instructions until the engine fires. Once the engine starts, move the choke lever on the engine halfway between CHOKE and RUN.
    7. If the engine does not fire after three attempts, move the choke lever halfway between CHOKE and RUN position and try again.
    8. After the engine starts, move the throttle control to the IDLE position for a few minutes to warm up, then move the choke lever to the RUN position as the engine warms up.

  • Why does my Craftsman 247.797852 keep shutting off?

    If the engine keeps shutting off, possible causes and corrective actions include:

    • Fuel tank empty, or stale fuel: Fill the tank with clean, fresh fuel.
    • Spark plug wire disconnected: Connect the wire to the spark plug.
    • Faulty spark plug: Clean, adjust gap, or replace the spark plug.
    • Unit running on CHOKE: Move the choke lever to the OFF position.
    • Blocked fuel line or stale fuel: Clean the fuel line and fill the tank with clean, fresh gasoline.
    • Water or dirt in the fuel system: Disconnect the fuel line at the carburetor to drain the fuel tank, then refill with fresh fuel.
    • Carburetor out of adjustment: Adjust the carburetor or contact a SEARS Service Center.
    • Dirty air cleaner: Service the air cleaner.
    • Engine oil level low: Fill the crankcase with proper oil.
    • Loose parts or damaged impeller: Stop the engine immediately, disconnect the spark plug wire, tighten all bolts and nuts, and make all necessary repairs. If vibration continues, have the unit serviced by a SEARS Service Center.

    For more information, see page 16 of the manual.

  • What size branches can the Craftsman 247.797852 handle?

    The chipper shredder can handle leaves and small branches up to 1/2 inch in diameter when fed into the hopper assembly. For bulky material, such as stalks or heavy branches, up to 3 inches in diameter, it should be fed into the chipper chute.

  • Why is my Craftsman 247.797852 not chipping effectively?

    If the chipper-shredder is not chipping effectively, indicated by the composition of the material being discharged changing (becomes stringy, etc.) or if the rate at which the material is discharged slows down considerably, it is likely that the shredding blade and/or chipper blades are dull and need to be sharpened or replaced.


    For more information, see page 10 of the manual.

  • How do I clean the air filter on the Craftsman 247.797852?

    To clean the air filter, service the cartridge at three-month intervals or every 25 hours, whichever comes first, or more often under dusty conditions:

    1. Loosen the screws and tilt the cover as illustrated.
    2. Carefully remove the pre-cleaner and cartridge.
    3. Clean the cartridge by tapping gently on a flat surface. If very dirty, replace the cartridge and pre-cleaner or clean as follows:
      • Wash in a low or non-sudsing detergent and warm water solution. Do not use petroleum solvents such as kerosene.
      • Rinse thoroughly with flowing water from inside out until the water is clear.
      • Allow the cartridge to stand and air dry thoroughly before using. Do not oil the cartridge or pre-cleaner, and do not use pressurized air to clean or dry the cartridge.
    4. Install the cartridge and pre-cleaner.
    5. Close the cover and fasten the screws securely.

    For more information, see page 11 of the manual.

  • Where is the spark plug located on the Craftsman 247.797852?

  • What pre-season maintenance is recommended for the Craftsman 247.797852?

    For long periods of storage, such as pre-season, it is recommended to prepare your chipper-shredder to prevent engine damage and maintain good operating condition:

    • Fuel System: Remove gasoline by running the engine until the tank is empty and the engine stops, then disconnecting the fuel line to drain any remaining fuel. Alternatively, Sears Craftsman Fuel Stabilizer No. 33500 may be added to any gasoline left in the tank to minimize gum deposits and acids. If using stabilizer, run the engine at least 10 minutes after adding it to allow the mixture to reach the carburetor.
    • Oil Change: Change the engine oil.
    • Piston/Cylinder Lubrication: Remove the spark plug and squirt clean engine oil into the spark plug hole. Cover the spark plug hole with a rag, then rotate the engine by pulling the starter two or three times. Reinstall the spark plug and attach the spark plug wire.
    • Cleaning: Thoroughly clean the chipper-shredder.
    • Rust Prevention: If storing in an unventilated or metal storage shed, coat metal parts with a light oil or silicone to prevent rust.
    • Storage Location: Store in a clean, dry area. Do not store next to corrosive materials, such as fertilizer.

    For more information, see page 12 of the manual.
