The Storage preparation process for the CRAFTSMAN 247.885690 begins with ensuring the engine is cool and the machine is on a stable, level surface. Disconnect the spark plug wire or remove the battery if applicable to prevent accidental starting during storage. Clean the exterior of the equipment to remove dirt, grass clippings, and oil residues that can attract moisture and cause corrosion over time. Lubricate moving parts as recommended by the manufacturer, paying particular attention to pivot points, wheels, and the drive belt areas, then wipe away any excess lubricant to prevent attracting dust. Perform a final inspection to verify there are no loose hardware items, and store the unit in a dry, well-ventilated location to minimize rust and deterioration. Consider covering the equipment with an appropriate breathable cover to protect it from dust while allowing moisture to escape.

During long-term storage, it is important to drain or stabilize fuel according to the engine type and local regulations to prevent gum formation in the carburetor and fuel lines. If the machine uses a gasoline engine, run the fuel until the float bowl is empty or treat the fuel with a recommended stabilizer, then start and run the engine for several minutes to circulate the stabilized fuel. For units with a gasoline/oil mix, ensure the correct ratio is maintained and avoid leaving mixed fuel in the tank beyond the recommended storage period. For electric-start models, disconnect the battery and store it on a charger or in a cool, dry place where temperatures remain relatively constant to extend battery life. Always refer to the original equipment manufacturer’s guidelines for specific storage intervals and procedures.

Disposal and recycling considerations for the CRAFTSMAN 247.885690 require adherence to local, state, and federal regulations regarding hazardous materials and components. Do not dispose of oil, fuel, or battery liquids in regular trash or sewer systems; instead, take them to an approved recycling or hazardous waste facility. Remove and properly recycle or dispose of any spent batteries, batteries that are swollen or damaged, and containers that held fuel or oil, following the manufacturer’s instructions and environmental guidelines. When replacing components, choose OEM parts whenever possible to maintain safety and performance standards, and document any disposal or recycling actions for maintenance records. If the unit contains refrigerants, solvents, or other regulated substances, ensure they are recovered by licensed technicians in accordance with environmental protection regulations.

Before returning the tool to service after storage, perform a thorough pre-use inspection to verify that all safety features are functional and that no components have degraded during storage. Check the spark plug condition or ignition system, fuel system integrity, and electrical connections for corrosion or wear. Inspect the air filter, muffler, and cooling fins for blockages or damage, and replace any worn components as needed. Re-torque fasteners to the manufacturer’s specified values and perform a test run in safe conditions to confirm proper operation. Maintain a record of storage and end-of-life procedures to support warranty requirements and future maintenance planning.
