Store in a dry, weather-protected area with minimal exposure to direct sunlight, which can degrade plastics and rubber components over time. Elevate equipment off the floor on stable stands or shelves to promote air circulation and mitigate moisture exposure at the base. Inspect all lubricants and fluids, top off as needed, and label the unit with the date of service to aid in future maintenance scheduling. When possible, keep a maintenance log nearby to track recurring tasks and remind you of seasonal service intervals.
Transport precautions are essential to prevent damage to sensitive systems and to ensure safe handling during movement. Before loading, perform a quick visual check for loose fasteners, fuel containers, and accessories that could become projectiles or cause imbalance during transit. Use appropriate lifting techniques and, when feasible, mechanical aids such as dollies or ramps to reduce the risk of back injuries and equipment damage. Secure the unit with straps or ties to an anchor point in the vehicle to prevent shifting, and place a protective mat under the base to absorb vibrations and protect the finish. If transporting in a trailer, ensure there is adequate clearance and proper ventilation, especially for gasoline-powered units, to minimize fumes and heat buildup. Always follow local regulations regarding transporting hazardous materials like fuels and ensure containers are sealed to prevent spills.
Disposal and recycling guidelines are designed to minimize environmental impact and comply with waste management regulations. Remove all remaining fuel and fluids from the machine using approved containment and disposal methods, storing them in certified containers for later recycling or safe disposal. Separate recyclable metal components, batteries, and plastics according to regional guidelines, and take them to certified facilities where possible. Decommission used or irreparable parts in accordance with local environmental requirements, avoiding incineration or dumping in normal waste streams. When in doubt, consult the manufacturer’s approved recycling partners or local municipal programs to ensure proper handling of components such as batteries, capacitors, and electronic controls. Document disposal actions for service records to demonstrate compliance and to assist with future warranty and service planning.
